MX104 3D Universal Edge Router Overview

The Juniper Networks MX104 3D Universal Edge Router is optimized for aggregating
mobile, enterprise WAN, business, and residential access services. The MX104 router is
designed for high-density access and pre-aggregation and is environmentally hardened
to allow outside deployments in cabinets and remote terminals. The router is a
high-performance router functioning as a universal aggregation platform for mobile
broadband and metro Ethernet applications. It also acts as a universal edge platform
supporting all types of private WAN, data center interconnect, Internet edge, business
edge, and residential edge services.

The router is powered by the Junos Trio chipset and runs the Junos operating system
(Junos OS) for high-performance routing and switching. For a list of related Junos OS
documentation, see http://www.juniper.net/techpubs/software/junos/.
The chassis is a rigid sheet metal structure that houses all the other router components
(see Figure 1 on page 4 and Figure 2 on page 4). The hardware system provides resiliency
and redundancy, including power supplies and Routing Engines. The chassis also has
four built-in 10-Gigabit Ethernet SFP+ ports and four slots that accept Modular Interface
Cards (MICs). For a list of the supported MICs, see the MX Series Interface Module Reference.
The router is environmentally hardened and is 3.5 rack units (U; that is, 6.125 in., or 15.55
cm) tall. Several routers can be stacked in a single floor-to-ceiling rack, for increased
port density per unit of floor space. The chassis is installed in standard 11.81 in. (30
cm)-deep (or larger) enclosed cabinets, 19-in. equipment racks, or telco open-frame
racks.

Chapter 1: System Overview

MX104 Component Redundancy

The MX104 chassis provides redundancy and resiliency. The hardware system is fully
redundant, including power supplies, Routing Engines, and cooling system.
A fully configured router is designed so that no single point of failure can cause the entire
system to fail. Only a fully configured router provides complete redundancy. All other
configurations provide partial redundancy. The following major hardware components
are redundant:

Related
Documentation

Power suppliesIn a redundant configuration, the router contains either two AC or DC

power supplies that install into the front of the chassis. The slots are labeled PS 0 and
PS 1 (left to right). Each power supply provides power to all components in the router.
When two power supplies are present, they share power almost equally within a fully
populated system. If one power supply in a redundant configuration fails or is removed,
the remaining power supplies assume the entire electrical load without interruption.
Two power supplies provide the maximum configuration with full power for as long as
the router is operational.

Routing EngineIf two Routing Engines are installed, one functions as the master and
the other functions as the backup. If the master Routing Engine fails, the backup can
take over as the master.

Cooling systemThe cooling system has redundant components, which are controlled
by the host subsystem. If one of the fans fails, the host subsystem increases the speed
of the remaining fans to provide sufficient cooling for the router indefinitely.

MX104 Alarm Contact Port Overview

The MX104 router has four external alarm contacts (also known as potential free contacts)
for connecting the router to external alarm devices. The port labeled ALARM uses a 15-pin
D-type connector. The external alarm contact has 15 pins that accept a single core wire
from external alarm devices. A DE-15 alarm cable is required to connect the MX104 router
to external alarm devices. Use the gauge wire appropriate for the external device that
you are connecting.
Whenever a system condition triggers an alarm, the alarm relay contacts are activated,
which in turn activates the external alarm devices. The alarm setting is open or closed.
You can connect and configure two output alarms and four input alarms. Two additional
output alarms are reserved and are used to indicate major and minor system alarms.
Each output and input alarm has two contacts for connecting the router to external alarm
devices. Contact 1 of each alarm can be configured as Normally Open [NO] or Normally
Closed [NC] through the CLI. Contact 2 of each alarm functions as a reference [REF] or
negative potential terminal for Contact 1 of the corresponding alarm and provides a
current path for external alarm devices. Table 4 on page 10 describes the functions of
the alarm contacts.

MX104 Clocking and Timing Ports Overview

Four Subminiature B (SMB) connectors (for 10-MHz and 1-PPS), one RJ-48 port (for
BITS), and one RS-232 port (for TOD) on the front panel of the router connect to external
clock signal sources. The clocking ports provide the synchronized output clocks from any
one of the reference clock inputs based on the clocks priority.
The reference clock inputs can be Ethernet-recovered clocks, T1 or E1 line clocks, IEEE
1588v2-recovered clocks, BITS timing, 10-MHz timing, and 1-PPS timing. The T1 or E1 line
clock also supports loop timing. These clocking ports distribute a synchronized clock
signal throughout the chassis by locking onto the selected clock source. In the absence
of these configured ports, the local oscillator present in the system provides the chassis
synchronization.
Clock sources within the MX104 router include:

External clock timing port

10-MHz timing connectors (one input and one output)

1-pulse-per-second (PPS) connectors (one input and one output)

Time-of-day (TOD) RS-232 port

Synchronous Ethernet support on SFP ports as timing input or output

Packet (IEEE 1588-2008) v2 timing includes:

Timing input when configured as Ordinary Clock (OC) or Boundary Clock (BC)

Timing output when configured as BC

MX104 Cooling System and Airflow Overview

The cooling system in an MX104 router consists of the following components (see
Figure 9 on page 19):

Fan tray

Air filter

g007621

Figure 9: MX104 Fan Tray and Air Filter

The router has one hot-swappable fan tray that contains five fans. The air filter installs
into the side of the fan tray. The air intake to cool the chassis is located on the right side
of the chassis next to the air filter. Air is pulled through the air filter toward the fan tray,

MX104 3D Universal Edge Router Hardware Guide

where it is exhausted out the left side of the system (see Figure 10 on page 20). The
exhaust for the power supplies is located on the left side of the chassis.

Figure 10: Cooling System and Airflow in an MX104 Router

The cooling system components work together to keep all router components within the
acceptable temperature range. The chassis monitors the temperature of the router
components. When the router is operating normally, the fans function at lower than full
speed. If a fan fails or the ambient temperature rises above a threshold, the speed of the
remaining fans is automatically adjusted to keep the temperature within the acceptable
range. If the ambient maximum temperature specification is exceeded and the system
cannot be adequately cooled, the Routing Engine shuts down the system by disabling
output power from each power supply.

MX104 Routing Engine Overview

The Routing Engine is a Freescale-based PC platform that runs Junos OS. Software
processes that run on the Routing Engine maintain the routing tables, manage the routing
protocols used on the router, control the router interfaces, control some chassis
components, and provide the interface for system management and user access to the
router.
You can install one or two Routing Engines in the router. The Routing Engines install into
the front of the chassis. Two USB ports on the Routing Engine accepts a USB memory
card that allow you to load Junos OS.
If two Routing Engines are installed, one functions as the master and the other acts as
the backup. If the master Routing Engine fails or is removed and the backup is configured
appropriately, the backup takes over as the master. The backup Routing Engine is
hot-insertable and hot-removable.
The MX104 router supports the Routing Engine with model number RE-MX104.

MX104 Routing Engine Components

Five ports, located on the right side of the Routing Engine, connect the Routing Engine
to one or more external devices on which system administrators can issue Junos OS
command-line interface (CLI) commands to manage the router.
The Routing Engine consists of the following components:

1.8-GHz CPURuns Junos OS to maintain the router's routing tables and routing
protocols.

4-GB DDR3 RAM (mini DIMM)Provides storage for the routing and forwarding tables
and for other Routing Engine processes.

8-GB on-board NAND FlashProvides primary storage for software images,

configuration files, and microcode. The NAND flash is fixed and is inaccessible from
outside the router.

Interface portsProvides access to management devices.

AUXNot supported.

CONSOLEConnects the Routing Engine to a system console through a serial cable

with an RJ-45 connector.

ETHERNETConnects the Routing Engine through an Ethernet connection to a

management LAN (or any other device that plugs into an Ethernet connection) for
out-of-band management. The port uses an autosensing RJ-45 connector to support
10-Mbps, 100-Mbps, or 1000-Mbps connections. Two small LEDs on the right of the
port indicate the connection in use: see MX104 Routing Engine LEDs on page 23.

Two USB portsProvides a removable media interface through which you can install
the Junos OS manually. Junos OS supports USB version 1.0.

MX104 Routing Engine Buttons on page 22).

Reset buttonReboots the Routing Engine when pressed (see MX104 Routing Engine
Buttons on page 22).

MX104 Routing Engine Buttons

Each Routing Engine has two push-button controls. The buttons, labeled ONLINE OFFLINE,
and RESET, are located directly on the faceplate of the Routing Engine. Table 11 on page 23
describes the functions of the buttons.

MX104 Boot Sequence

The MX104 router ships with Junos OS preinstalled and ready to be configured when the
router is powered on. One eight-GB internal NAND Flash memory (da0) acts as the hard
drive. Two USB ports on the front panel accept USB storage devices (usb0 and usb1)
that can also function as alternative boot devices.
When the router boots, it first attempts to start the image on the USB 0 flash memory
device, if present, then attempts to start the image on the USB 1 flash memory device, if
present. If a USB flash memory device is not inserted into either of the two slots on the
Routing Engine, or the attempt otherwise fails, the router next tries the active partition
on the NAND Flash device.

MX104 Modular Interface Card (MIC) Overview on page 56

MX104 Modular Interface Card (MIC) Overview

MICs receive incoming packets from the network and transmit outgoing packets to the
network. During this process, each MIC performs framing and high-speed signaling for
its media type. Before transmitting outgoing data packets through the MIC interfaces,
the Packet Forwarding Engine encapsulates the packets received.
The MX104 routers support the following types of MICs:

Front-Pluggable MICs on page 45

Built-in 10-Gigabit Ethernet MIC on page 45

MIC LEDs on page 47

Front-Pluggable MICs
Modular Interface Cards (MICs) install into four slots in the front of the MX104 router and
provide the physical connections to various network media types. MICs are hot-removable
and hot-insertable. The slots are labeled 0/0, 0/1, 1/0, and 1/1. You can install MICs of
different media types on the same router as long as the router supports those MICs. For
complete specifications, see MICs Supported by MX Series Routers on page 47 in the
MX Series Interface Module Reference.

Built-in 10-Gigabit Ethernet MIC

The built-in 10-Gigabit Ethernet MIC is fixed on the MX104 router. The MIC is labeled XE
and is located on the front panel.

NOTE: If you ordered a license for the built-in 10-Gigabit Ethernet ports on
the MX104 and you do not receive a paper license with your shipment, open
a case with customer support. See Contacting Customer Support on page 201
for more information.

Identifying Interface Numbers on the Hardware

Each MX104 router has three built-in MPCs, which are represented in the CLI as FPC 0
through FPC 2. The numbering of the MPCs is from bottom to top (see
Figure 14 on page 52).

NOTE: The port numbers on MICs correspond to the port numbers on the
interface. The port numbering on the MIC-3D-20GE-SFP-EH MIC depicted
in Figure 14 on page 52 is only one example of the port numbering for MICs.
Each MIC might number ports differentlyhorizontally or vertically, for
exampleand it is important to review the port numbering for your particular
MIC in the MX Series Interface Module Reference.

MPC 0 and MPC 1 have two slots each that accept MICs. The MICs are represented as
MIC 0 and MIC 1 in the CLI and are logically divided into PICs depending on their type. A
MIC installed in the left-most MIC slot (0/0 or 1/0) is represented in the CLI as PIC 0 and

MX104 3D Universal Edge Router Hardware Guide

PIC 1. A MIC installed in the right-most MIC slot (0/1 or 1/1) is represented as PIC 2 and
PIC 3.

MPC 2 houses a 4-port 10-Gigabit Ethernet MIC. Both the MPC and the MIC are considered
fixed and are built into the front panel of the chassis. The MPC is represented as FPC 2
in the CLI. The MIC is represented as MIC 0 in the CLI and is logically divided into a single
PIC, which is represented as PIC 0.

MX104 Modular Interface Card (MIC) Overview

MICs receive incoming packets from the network and transmit outgoing packets to the
network. During this process, each MIC performs framing and high-speed signaling for
its media type. Before transmitting outgoing data packets through the MIC interfaces,
the Packet Forwarding Engine encapsulates the packets received.
The MX104 routers support the following types of MICs:

Front-Pluggable MICs on page 56

Built-in 10-Gigabit Ethernet MIC on page 56

MIC LEDs on page 57

Front-Pluggable MICs
Modular Interface Cards (MICs) install into four slots in the front of the MX104 router and
provide the physical connections to various network media types. MICs are hot-removable
and hot-insertable. The slots are labeled 0/0, 0/1, 1/0, and 1/1. You can install MICs of
different media types on the same router as long as the router supports those MICs. For
complete specifications, see MICs Supported by MX Series Routers on page 47 in the
MX Series Interface Module Reference.

Built-in 10-Gigabit Ethernet MIC

The built-in 10-Gigabit Ethernet MIC is fixed on the MX104 router. The MIC is labeled XE
and is located on the front panel.

NOTE: If you ordered a license for the built-in 10-Gigabit Ethernet ports on
the MX104 and you do not receive a paper license with your shipment, open
a case with customer support. See Contacting Customer Support on page 201
for more information.

1+1 redundancy. Each power supply has a handle, an ejection tab, and a status LED.

CAUTION: The router cannot be powered from AC and DC power supplies

simultaneously.

When two power supplies are present, they share power almost equally within a fully
populated system. If one power supply in a redundant configuration fails or is removed,
the remaining power supply assumes the entire electrical load without interruption. A
single power supply provides the maximum configuration with full power for as long as
the router is operational. A second power supply can be installed for redundancy. Each
power supply is cooled by its own internal cooling system.
Redundant power supplies are hot-removable and hot-insertable. When you remove a
power supply from a router that uses only one power supply, the router might shut down
depending on your configuration.

MX104 Router Environmental Specifications on page 68

MX104 Router Environmental Specifications

The router must be installed in a rack or cabinet housed in a dry, clean, well-ventilated,
and temperature-controlled environment.
Ensure that these environmental guidelines are followed:

The site must be as dust-free as possible, because dust can clog air intake vents and
filters, reducing the efficiency of the router cooling system.

Maintain ambient airflow for normal router operation. If the airflow is blocked or
restricted, or if the intake air is too warm, the router might overheat, leading to the
router temperature monitor shutting down the router to protect the hardware
components.

NOTE: Depending on the ambient temperature, it may take up to 5 minutes

for the router to heat up to the operating temperature.

Table 50 on page 68 provides the required environmental conditions for normal router
operation.

Rack type

Use a two-post rack or a four-post rack. You can mount the router on any two-post or four-post
rack that provides bracket holes or hole patterns spaced at 1 U (1.75 in., or 4.45 cm) increments and
that meets the size and strength requirements to support the weight.
A U is the standard rack unit defined in Cabinets, Racks, Panels, and Associated Equipment (document
number EIA-310D) published by the Electronics Industry Association (http://www.eia.org).
The rack must meet the strength requirements to support the weight of the chassis.

Mounting bracket hole

spacing

The holes in the mounting brackets are spaced at 1 U (1.75 in., or 4.45 cm) so that the router can be
mounted in any rack that provides holes spaced at that distance.

Rack size and strength

Ensure that the rack complies with this standard:

Cabinet Requirement

Guidelines

Cabinet airflow requirements

When you mount the router in a cabinet, ensure that ventilation

through the cabinet is sufficient to prevent overheating.

Related
Documentation

Ensure an adequate cool air supply to dissipate the thermal

output of the router or routers.

Ensure that the cabinet allows the hot exhaust air from the
chassis to exit the cabinet without recirculating into the
router. An open cabinet (without a top or doors) that
employs hot air exhaust extraction from the top allows the
best airflow through the chassis. If the cabinet contains a
top or doors, perforations in these elements assist with
removing the hot air exhaust.

Install the router in the cabinet in a way that maximizes the

open space on the side of the chassis that has the hot air
exhaust. This space maximizes the clearance for critical
airflow.

Route and dress all cables to minimize the blockage of

airflow to and from the chassis.

Ensure that the spacing of rails and adjacent cabinets allows

for proper clearance around the router and cabinet.

A cabinet larger than the minimum required provides better

airflow and reduces the chance of overheating.

Clearance Requirements for Airflow and Hardware Maintenance on MX104 Routers

When planning the installation site, allow sufficient clearance around the rack (see
Figure 19 on page 73):

72

For the cooling system to function properly, the airflow around the chassis must be
unrestricted. Allow at least 6 in. (15.2 cm) of clearance between side-cooled routers.
Allow 2.8 in. (7 cm) between the side of the chassis and any non-heat-producing
surface such as a wall.

For service personnel to remove and install hardware components, there must be
adequate space at the front and back of the router. At least 24 in. (61 cm) is required
both in front of and behind the router. NEBS GR-63 recommends that you allow at
least 30 in. (72.6 cm) in front of the rack and 24 in. (61.0 cm) behind the router.

Grounding Cable Specifications on page 75

Grounding Points Specifications

To meet safety and electromagnetic interference (EMI) requirements and to ensure
proper operation, the router must be adequately grounded before power is connected.
To ground AC-powered and DC-powered routers, you must connect a grounding cable
to earth ground and then attach it to the chassis grounding points using two washers
and two screws (see Figure 20 on page 74).
Two threaded holes are provided on the front the router chassis for connecting the router
to earth ground. The grounding points fit SAE 10-32 screws (American). The grounding
points are spaced at 0.625-in. (15.86-mm) centers.

73

MX104 3D Universal Edge Router Hardware Guide

Figure 20: Grounding Points on the MX104 Routers

NOTE: All bare grounding connection points to the router must be cleaned
and coated with an antioxidant solution before grounding the router.

NOTE: All surfaces on the router that are unplated must be brought to a
bright finish and treated with an antioxidant solution before connecting the
router.

NOTE: All nonconductive surfaces on the router must be removed from all
threads and connection points to ensure electrical continuity.

Grounding Cable Lug Specifications

The grounding cable lug is used to secure the grounding cable to the grounding points
on the chassis. The grounding cable lug attaches to the grounding cable (see
Figure 21 on page 75) and is secured to the router by two SAE 10-32 screws. We
recommend using washers between the grounding lug and the screws. The grounding
cable lug, screws, and washers are supplied with the router.

74

Chapter 7: Preparation Overview

Figure 21: Grounding Cable Lug

CAUTION: Before router installation begins, a licensed electrician must attach

a cable lug to the grounding and power cables that you supply. A cable with
an incorrectly attached lug can damage the router.

CAUTION: The maximum torque rating of the grounding screws on the router
is 4.34 lb-in. (0.49 Nm). The grounding screws may be damaged if excessive
torque is applied. Use only a torque-controlled driver to tighten screws. Use
an appropriately sized driver, with a maximum torque capacity of 5 lb-in. or
less. Ensure that the driver is undamaged and properly calibrated and that
you have been trained in its use. You may wish to use a driver that is designed
to prevent overtorque when the preset torque level is achieved.

Grounding Cable Specifications

You must provide one grounding cable that meets the following specifications: 14-AWG
2
(1.63 mm ), minimum 90C wire, or as required by the local code.

CAUTION: If you are having a problem running a Juniper Networks device

that is using a third-party optic or cable, the Juniper Networks Technical
Assistance Center (JTAC) can help you diagnose the source of the problem.
Your JTAC engineer might recommend that you check the third-party optic
or cable and potentially replace it with an equivalent Juniper Networks optic
or cable that is qualified for the device.

NOTE: For XFP transceivers that can support either the 10-Gigabit Ethernet
or SONET OC192/STM64 specifications, check the standard supported for
the device into which the transceiver is installed. For example, the
XFP-10G-E-OC192-IR2 transceiver installed in a 10-Gigabit Ethernet PIC
supports the 10GBASE-E standard. However, the XFP-10G-E-OC192-IR2
transceiver installed in a SONET OC192/STM64 PIC supports the SONET
OC192/STM64 IR2 standard.

Understanding Fiber-Optic Cable Signal Loss, Attenuation, and Dispersion

This topic describes signal loss, attenuation, and dispersion in fiber-optic cable. For
information about calculating power budget and power margin for fiber-optic cable, see
Calculating Power Budget and Power Margin for Fiber-Optic Cables on page 86 and
Supported Network Interface Standards by Transceiver for ACX, M, MX, and T Series
Routers on page 78 or Supported Network Interface Standards by Transceiver for PTX
Series Routers.

Signal Loss in Multimode and Single-Mode Fiber-Optic Cable on page 85

Attenuation and Dispersion in Fiber-Optic Cable on page 85

Signal Loss in Multimode and Single-Mode Fiber-Optic Cable

Multimode fiber is large enough in diameter to allow rays of light to reflect internally
(bounce off the walls of the fiber). Interfaces with multimode optics typically use LEDs
as light sources. However, LEDs are not coherent sources. They spray varying wavelengths
of light into the multimode fiber, which reflects the light at different angles. Light rays
travel in jagged lines through a multimode fiber, causing signal dispersion. When light
traveling in the fiber core radiates into the fiber cladding, higher-order mode loss (HOL)
results. Together these factors limit the transmission distance of multimode fiber
compared with single-mode fiber.
Single-mode fiber is so small in diameter that rays of light can reflect internally through
one layer only. Interfaces with single-mode optics use lasers as light sources. Lasers
generate a single wavelength of light, which travels in a straight line through the
single-mode fiber. Compared with multimode fiber, single-mode fiber has higher
bandwidth and can carry signals for longer distances.
Exceeding the maximum transmission distances can result in significant signal loss, which
causes unreliable transmission.

Attenuation and Dispersion in Fiber-Optic Cable

Correct functioning of an optical data link depends on modulated light reaching the
receiver with enough power to be demodulated correctly. Attenuation is the reduction in
power of the light signal as it is transmitted. Attenuation is caused by passive media
components, such as cables, cable splices, and connectors. Although attenuation is

Copyright 2015, Juniper Networks, Inc.

85

MX104 3D Universal Edge Router Hardware Guide

significantly lower for optical fiber than for other media, it still occurs in both multimode
and single-mode transmission. An efficient optical data link must have enough light
available to overcome attenuation.
Dispersion is the spreading of the signal in time. The following two types of dispersion
can affect an optical data link:

Chromatic dispersionSpreading of the signal in time resulting from the different

speeds of light rays.

Modal dispersionSpreading of the signal in time resulting from the different

propagation modes in the fiber.

For multimode transmission, modal dispersion, rather than chromatic dispersion or

attenuation, usually limits the maximum bit rate and link length. For single-mode
transmission, modal dispersion is not a factor. However, at higher bit rates and over longer
distances, chromatic dispersion rather than modal dispersion limits maximum link length.
An efficient optical data link must have enough light to exceed the minimum power that
the receiver requires to operate within its specifications. In addition, the total dispersion
must be less than the limits specified for the type of link in Telcordia Technologies
document GR-253-CORE (Section 4.3) and International Telecommunications Union
(ITU) document G.957.
When chromatic dispersion is at the maximum allowed, its effect can be considered as
a power penalty in the power budget. The optical power budget must allow for the sum
of component attenuation, power penalties (including those from dispersion), and a
safety margin for unexpected losses.

Calculating Power Budget and Power Margin for Fiber-Optic Cables

Use the information in this topic and the information in Supported Network Interface
Standards by Transceiver for ACX, M, MX, and T Series Routers on page 78 or Supported
Network Interface Standards by Transceiver for PTX Series Routers to calculate the power
budget and power margin for fiber-optic cables.
To calculate the power budget and power margin, perform the following tasks:
1.

Calculating Power Budget for Fiber-Optic Cable on page 86

2. Calculating Power Margin for Fiber-Optic Cable on page 87

Calculating Power Budget for Fiber-Optic Cable

To ensure that fiber-optic connections have sufficient power for correct operation, you
need to calculate the link's power budget, which is the maximum amount of power it
can transmit. When you calculate the power budget, you use a worst-case analysis to
provide a margin of error, even though all the parts of an actual system do not operate
at the worst-case levels. To calculate the worst-case estimate of power budget (P ),
B

you assume minimum transmitter power (P ) and minimum receiver sensitivity (P ):

T

Chapter 8: Transceiver and Cable Specifications

P =P P

The following hypothetical power budget equation uses values measured in decibels
(dB) and decibels referred to one milliwatt (dBm):
P =P P
B

P = 15 dBm (28 dBm)

B

P = 13 dB
B

Calculating Power Margin for Fiber-Optic Cable

After calculating a link's power budget, you can calculate the power margin (P ), which
M

represents the amount of power available after subtracting attenuation or link loss (LL)
from the power budget (P ). A worst-case estimate of P assumes maximum LL:
B

P = P LL
M

A P greater than zero indicates that the power budget is sufficient to operate the receiver.
M

Factors that can cause link loss include higher-order mode losses (HOL), modal and
chromatic dispersion, connectors, splices, and fiber attenuation. Table 55 on page 87
lists an estimated amount of loss for the factors used in the following sample calculations.
For information about the actual amount of signal loss caused by equipment and other
factors, refer to vendor documentation.

The following example uses the estimated values in Table 55 on page 87 to calculate
link loss (LL) for a 2-km-long multimode link with a power budget (P ) of 13 dB:
B

Fiber attenuation for 2 km @ 1.0 dB/km = 2 dB

Loss for five connectors @ 0.5 dB per connector = 5(0.5 dB) = 2.5 dB

Copyright 2015, Juniper Networks, Inc.

87

MX104 3D Universal Edge Router Hardware Guide

Loss for two splices @ 0.5 dB per splice = 2(0.5 dB) = 1 dB

Higher-order mode loss = 0.5 dB

Clock recovery module = 1 dB

The power margin (P ) is calculated as follows:

M

P = P LL
M

P = 13 dB 2 km (1.0 dB/km) 5 (0.5 dB) 2 (0.5 dB) 0.5 dB [HOL] 1 dB [CRM]

M

P = 13 dB 2 dB 2.5 dB 1 dB 0.5 dB 1 dB
M

P = 6 dB
M

The following sample calculation for an 8-km-long single-mode link with a power budget
(P ) of 13 dB uses the estimated values from Table 55 on page 87 to calculate link loss
B

(LL) as the sum of fiber attenuation (8 km @ 0.5 dB/km, or 4 dB) and loss for seven
connectors (0.5 dB per connector, or 3.5 dB). The power margin (P ) is calculated as
M

follows:
P = P LL
M

P = 13 dB 8 km (0.5 dB/km) 7(0.5 dB)

M

P = 13 dB 4 dB 3.5 dB
M

P = 5.5 dB
M

In both examples, the calculated power margin is greater than zero, indicating that the
link has sufficient power for transmission and does not exceed the maximum receiver
input power.

MX104 Clocking and Timing Ports Overview

Four Subminiature B (SMB) connectors (for 10-MHz and 1-PPS), one RJ-48 port (for
BITS), and one RS-232 port (for TOD) on the front panel of the router connect to external
clock signal sources. The clocking ports provide the synchronized output clocks from any
one of the reference clock inputs based on the clocks priority.
The reference clock inputs can be Ethernet-recovered clocks, T1 or E1 line clocks, IEEE
1588v2-recovered clocks, BITS timing, 10-MHz timing, and 1-PPS timing. The T1 or E1 line
clock also supports loop timing. These clocking ports distribute a synchronized clock
signal throughout the chassis by locking onto the selected clock source. In the absence
of these configured ports, the local oscillator present in the system provides the chassis
synchronization.
Clock sources within the MX104 router include:

External clock timing port

10-MHz timing connectors (one input and one output)

1-pulse-per-second (PPS) connectors (one input and one output)

Time-of-day (TOD) RS-232 port

MX104 AC Power Cord Specifications

Each AC power supply has a single AC appliance inlet that requires a dedicated AC power
feed. Most sites distribute power through a main conduit that leads to frame-mounted
power distribution panels, one of which can be located at the top of the rack that houses
the router. An AC power cord connects each power supply to the power distribution panel.
You can order detachable AC power cords, each approximately 8 ft (2.5 m) long that
supply AC power to the router. The C15 appliance coupler at the female end of the cord,
as described by International Electrotechnical Commission (IEC) standard 60320, inserts
into the AC appliance inlet coupler. The plug at the male end of the power cord fits into
the power source receptacle that is standard for your geographic location.

Installing the MX104 Router in the Rack

NOTE: The router can be installed horizontally in a rack or cabinet.

To install the router in the rack (see Figure 24 on page 117):

CAUTION: Before front mounting the router in a rack, have a qualified

technician verify that the rack is strong enough to support the router's weight
and is adequately supported at the installation site.

NOTE: One person must be available to lift the router while another secures
it to the rack.

CAUTION: If you are mounting multiple units on a rack, mount the heaviest
unit at the bottom of the rack and mount the other units from the bottom of
the rack to the top in decreasing order of the weight of the units.

1.

Ensure that the rack is in its permanent location and is secured to the building. Ensure
that the installation site allows adequate clearance for both airflow and maintenance.

2. Position the router in front of the rack or cabinet.

3. Hold onto the bottom of the chassis and carefully lift it so that the mounting brackets

contact the rack rails.

WARNING: To prevent injury, keep your back straight and lift with your
legs, not your back. Avoid twisting your body as you lift. Balance the load
evenly and be sure that your footing is solid.

4. Align the mounting brackets with the holes in the rack rails.
5. Install a mounting screw into each of the open mounting holes aligned with the rack,

starting from the bottom.

6. Visually inspect the alignment of the router. If the router is installed properly in the

rack, all the mounting screws on one side of the rack should be aligned with the
mounting screws on the opposite side and the router should be level.

overtighten the screw. (Use a number 2 Phillips screwdriver.)

CAUTION: Ensure that each grounding cable lug seats flush against the
surface of the grounding points as you are tightening the screws. Ensure
that each screw is properly threaded into the grounding points. Applying
installation torque to the screw when it is improperly threaded may
damage the terminal.

CAUTION: The maximum torque rating of the grounding screws on the

router is 4.34 lb-in. (0.49 Nm). The grounding screws may be damaged if
excessive torque is applied. Use only a torque-controlled driver to tighten
screws. Use an appropriately sized driver, with a maximum torque capacity
of 5 lb-in. or less. Ensure that the driver is undamaged and properly
calibrated and that you have been trained in its use. You may wish to use
a driver that is designed to prevent overtorque when the preset torque
level is achieved.

9. Dress the grounding cable, and verify that it does not touch or block access to router

components, and that it does not drape where people could trip on it.

3. Remove the plastic cover protecting the terminal on the faceplate.

4. Verify that the DC power cables are correctly labeled before making connections to

the power supply. In a typical power distribution scheme where the return is connected
to chassis ground at the battery plant, you can use a multimeter to verify the resistance
of the 48V and return DC cables to chassis ground:
For 48V and 60V:
a. The cable with very high resistance (indicating an open circuit) to chassis ground
is the DC input cable ().
b. The cable with very low resistance (indicating a closed circuit) to chassis ground
is the return cable (+).
For +24V:
a. The cable with very low resistance (indicating a closed circuit) to chassis ground
is the DC input cable ().
b. The cable with very high resistance (indicating an open circuit) to chassis ground
is the return cable (+).

MX104 3D Universal Edge Router Hardware Guide

NOTE: The XFP cages and optics on the components are industry standard
parts that have limited tactile feedback for insertion of optics and fiber.
You need to insert the optics and fiber firmly until the latch is securely in
place.

4. Arrange the cable to prevent it from dislodging or developing stress points. Secure

the cable so that it is not supporting its own weight as it hangs to the floor. Place
excess cable out of the way in a neatly coiled loop.

CAUTION: Avoid bending fiber-optic cable beyond its minimum bend

radius. An arc smaller than a few inches in diameter can damage the cable

Initially Configuring the MX104 Router

The MX104 router ships with Junos OS preinstalled and ready to be configured when the
router is powered on. One 8-GB internal NAND Flash memory (da0) acts as the hard
drive. Two USB ports on the front panel accept USB storage devices (usb0 and usb1)
that can also function as alternative boot devices.
When the router boots, it first attempts to start the image on the USB 0 flash memory
device, if present, then attempts to start the image on the USB 1 flash memory device, if
present. If a USB flash memory device is not inserted into either of the two slots on the
Routing Engine, or the attempt otherwise fails, the router next tries the active partition
on the NAND Flash device.
You configure the router by issuing Junos OS command-line interface (CLI) commands,
either on a console device attached to the CONSOLE port on the front panel, or over a
telnet connection to a network connected to the Routing Engine ETHERNET port on the
front panel.
Gather the following information before configuring the router:

Name that the router will use on the network

Domain name that the router will use

IP address and prefix length information for the Ethernet interface

IP address of a default router

IP address of a DNS server

Password for the root user

MX104 Field-Replaceable Units (FRUs)

Field-replaceable units (FRUs) are router components that can be replaced at the
customer site. Replacing most FRUs requires minimal router downtime. The router uses
the following types of FRUs:

Hot-removable and hot-insertable FRUsYou can remove and replace these

components without powering off the router or disrupting the routing functions.

Hot-pluggable FRUsYou can remove and replace these components without powering
off the router, but the routing functions of the system are interrupted when the
component is removed.

Table 73 on page 139 lists the FRUs for the MX104 router. Before you replace a Routing
Engine, you must take the Routing Engine offline.

MX104 3D Universal Edge Router Hardware Guide

Before you begin connecting a fiber-optic cable to an optical transceiver installed in a

router, ensure that you have taken the necessary precautions for safe handling of lasers
(see General Laser Safety Guidelines for Juniper Networks Devices on page 229).
To connect a fiber-optic cable to an optical transceiver installed in a router:

WARNING: Do not look directly into a fiber-optic transceiver or into the ends
of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected
to transceivers emit laser light that can damage your eyes.

1.

If the fiber-optic cable connector is covered by a rubber safety cap, remove the cap.
Save the cap.

2. Remove the rubber safety cap from the optical transceiver. Save the cap.
3. Insert the cable connector into the optical transceiver (see Figure 36 on page 144).

4. Secure the cables so that they are not supporting their own weight. Place excess cable

out of the way in a neatly coiled loop. Placing fasteners on a loop helps cables maintain
their shape.

CAUTION: Do not bend fiber-optic cables beyond their minimum bend

radius. An arc smaller than a few inches in diameter can damage the cables
and cause problems that are difficult to diagnose.
Do not let fiber-optic cables hang free from the connector. Do not allow
fastened loops of cables to dangle, which stresses the cables at the
fastening point.

Effect of Taking the MX104 Routing Engine Offline

Before you replace a Routing Engine, you must take the Routing Engine offline. The
Routing Engine is hot-pluggable.
Normally, if two Routing Engines are installed in the router, RE 0 functions as the master
and RE 1 functions as the backup. You can remove the backup Routing Engine (or either
of its components) without interrupting the functioning of the router. If you take the
master Routing Engine offline, the backup Routing Engine becomes the master (the
router might reboot, depending on your configuration). If the router has only one Routing
Engine, taking the Routing Engine offline causes the router to shut down. The effect of

154

Chapter 21: Replacing Host Subsystem Components

taking the master Routing Engine offline varies depending on your configuration of high
availability features.
Table 74 on page 155 explains the effect of taking the Routing Engine offline.

Table 74: Effect of Taking the Routing Engine Offline

Type of Routing Engine

Effect of Taking the Routing Engine Offline

Nonredundant Routing
Engine

The router shuts down.

Backup Routing Engine

The functioning of the router is not interrupted. The backup Routing Engine is hot-removable and
hot-insertable.

Master Routing Engine

The backup Routing Engine becomes the master. The backup Routing Engine assumes Routing
Engine functions. The master Routing Engine is hot-pluggable. Removal or failure of the master
Routing Engine affects forwarding and routing based on the high availability configuration:

Dual Routing Engines without any high availability features enabledTraffic is interrupted
while the Packet Forwarding Engine is reinitialized. All kernel and forwarding processes are
restarted. When the switchover to the new master Routing Engine is complete, routing
convergence takes place and traffic is resumed.

Graceful Routing Engine switchover (GRES) is enabledGraceful Routing Engine switchover

preserves interface and kernel information. Traffic is not interrupted. However, graceful Routing
Engine switchover does not preserve the control plane. Neighboring routers detect that the
router has restarted and react to the event in a manner prescribed by individual routing protocol
specifications. To preserve routing without interruption during a switchover, graceful Routing
Engine switchover must be combined with nonstop active routing.

Nonstop active routing is enabled (graceful Routing Engine switchover must be configured for
nonstop active routing to be enabled)Nonstop active routing supports Routing Engine
switchover without alerting peer nodes that a change has occurred. Nonstop active routing
uses the same infrastructure as graceful Routing Engine switchover to preserve interface and
kernel information. However, nonstop active routing also preserves routing information and
protocol sessions by running the routing protocol process (rpd) on both Routing Engines. In
addition, nonstop active routing preserves TCP connections maintained in the kernel.

Graceful restart is configuredGraceful restart provides extensions to routing protocols so

that neighboring helper routers restore routing information to a restarting router. These
extensions signal neighboring routers about the graceful restart and prevent the neighbors
from reacting to the router restart and from propagating the change in state to the network
during the graceful restart period. Neighbors provide the routing information that enables the
restarting router to stop and restart routing protocols without causing network reconvergence.
Neighbors are required to support graceful restart. The routing protocol process (rpd) restarts.
A graceful restart interval is required. For certain protocols, a significant change in the network
can cause graceful restart to stop.

NOTE: Router performance might change if the backup Routing Engine's

configuration differs from the former master's configuration. For the most
predictable performance, configure the two Routing Engines identically,
except for parameters unique to each Routing Engine.
To configure Routing Engine-specific parameters and still use the same
configuration on both Routing Engines, include the appropriate configuration
statements under the re0 and re1 statements at the [edit groups] hierarchy
level and use the apply-groups statement. For instructions, see the Junos OS
Administration Library for Routing Devices.

Before you take a Routing Engine offline, see Effect of Taking the MX104 Routing Engine
Offline on page 154.
To take the Routing Engine offline:
1.

Determine whether the Routing Engine is functioning as the master or as the backup,
using one of the two following methods:

If the MASTER LED on the Routing Engine is lit, that Routing Engine is functioning
as the master.

Issue the show chassis routing-engine command.

user@host> show chassis routing-engine
Routing Engine status:
Slot 0:
Current state
Master
Election priority
Master (default)

The master Routing Engine is designated Master in the current state field.

Chapter 21: Replacing Host Subsystem Components

2. If the Routing Engine is functioning as the master, switch it to backup using the request

chassis routing-engine master switch command:

user@host> request chassis routing-engine master switch
3. On the console or other management device connected to the Routing Engine you

are removing, enter CLI operational mode and issue the request system halt command.
The command shuts down the Routing Engine cleanly, so its state information is
preserved:
user@host> request system halt

Wait until a message appears on the console confirming that the operating system
has halted.
For more information about the command, see the CLI Explorer.

NOTE: The SCB might continue forwarding traffic for approximately five
minutes after the request system halt command has been issued.

Removing an MX104 Routing Engine

Before you remove a Routing Engine, remove the cables that connect to it.

CAUTION: Before you replace a Routing Engine, you must take the Routing
Engine offline. If there is only one Routing Engine, taking the Routing Engine
offline shuts down the router.

CAUTION: If the Routing Engine to be replaced is currently functioning as the

master Routing engine, switch it to be the backup before removing it.

To remove a Routing Engine from (see Figure 44 on page 158):

1.

Take the Routing Engine offline gracefully.

2. Place an electrostatic bag or antistatic mat on a flat, stable surface.

3. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the

ESD points on the chassis.

4. Verify that the Routing Engine LEDs are off.
5. Loosen the captive screws on both sides of the Routing Engine.
6. Grasp the Routing Engine by the captive screws, and slide it about halfway out of the

chassis.
7. Place one hand underneath the Routing Engine to support it, and slide it completely

out of the chassis.

8. Place the Routing Engine on the antistatic mat.

MICs are hot-insertable and hot-removable. When you remove a MIC, the router continues
to function, although the MIC interfaces being removed no longer function.
In the MX104 router, the MICs can be installed in four slots in the front of the router. A
MIC weighs less than 2 lb (0.9 kg).
To remove a MIC (see Figure 47 on page 164):
1.

Place an electrostatic bag or antistatic mat on a flat, stable surface to receive the
MIC. If the MIC connects to fiber-optic cable, have ready a rubber safety cap for each
transceiver and cable.

2. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the

ESD points on the chassis.

3. Use one of the following methods to take the MIC offline:

Press its online/offline button. Use a narrow-ended tool that fits inside the opening
that leads to the button. Press and hold the button until the MIC OK/FAIL LED goes
off (about five seconds).

Issue the following CLI command:

user@host> request chassis mic fpc-slot slot-number mic-slot slot-number offline

4. Label the cables connected to the MIC so that you can later reconnect each cable to

the correct MIC.

5. Disconnect the cables from the MIC. If the MIC uses a fiber-optic cable, immediately

cover each transceiver and the end of each cable with a rubber safety cap.

WARNING: Do not look directly into a fiber-optic transceiver or into the

ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable

Chapter 23: Replacing Power System Components

To install a DC power supply in the router, you need the following tools:

Phillips (+) screwdriver, number 2

ESD grounding wrist strap

Grounding ring lug with hole sized for an M5 screw

M5 nut and washer (one per DC power supply, attached)

DC power source cables, minimum 14 AWG or as required by local code (not provided)

DC power ring lugs, Panduit PV12-14HDRB-2k

M6 screws and washers (two per DC power supply, attached)

Grounding cable, minimum 14 AWG or as required by local code (not provided)

To install a DC power supply (see Figure 55 on page 175):

1.

Ensure that the voltage across the DC power source cable leads is 0 V and that there
is no chance that the cable leads might become active during installation.

2. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the

ESD points on the chassis.

3. Using both hands, slide the power supply straight into the chassis until the power

supply is fully seated in the chassis slot. The power supply faceplate should be flush
with any adjacent power supply faceplate or blank installed in the power supply slot.
4. Remove the clear plastic cover protecting the terminal on the faceplate.
5. Ground the DC power supply (see Figure 54 on page 173):

Remove the nut and washer from the grounding point on the power supply.

Secure each grounding cable lug to the grounding point with the washer and nut.

MX104 3D Universal Edge Router Hardware Guide

7. Verify that the DC power cables are correctly labeled before making connections to

the power supply. In a typical power distribution scheme where the return is connected
to chassis ground at the battery plant, you can use a multimeter to verify the resistance
of the DC cables to chassis ground:
For 48V and 60V:
a. The cable with very high resistance (indicating an open circuit) to chassis ground
is the DC input cable ().
b. The cable with very low resistance (indicating a closed circuit) to chassis ground
is the return cable (+).
For +24V:
a. The cable with very low resistance (indicating a closed circuit) to chassis ground
is the DC input cable ().
b. The cable with very high resistance (indicating an open circuit) to chassis ground
is the return cable (+).
8. Secure each power cable lug to the terminal with the flat washers and screw (see

Figure 56 on page 175). Apply up to 27.4 lb-in. (3.1 Nm) of torque to each screw. Do not
overtighten the screw. (Use a number 2 Phillips screwdriver.)
a. Secure the positive DC source power cable lug to the return (+) terminal.
b. Secure the negative DC source power cable lug to the input () terminal.

CAUTION: Ensure that each power cable lug seats flush against the surface
of the terminal block as you are tightening the screws. Ensure that each
screw is properly threaded into the terminal. Applying installation torque
to the screw when improperly threaded may result in damage to the
terminal.

CAUTION: The maximum torque rating of the terminal screws on the DC

power supply is 27.4 lb-in. (3.1 Nm). The terminal screws may be damaged
if excessive torque is applied. Use only a torque-controlled driver to tighten
screws on the DC power supply terminals. Use an appropriately sized
driver, with a maximum torque capacity of 27.4 lb-in. or less. Ensure that
the driver is undamaged and properly calibrated and that you have been
trained in its use. You may wish to use a driver that is designed to prevent
overtorque when the preset torque level is achieved.

9. Replace the clear plastic cover over the terminals on the faceplate.
10. Connect each DC power cable to the appropriate external DC power source.

174

Maintaining the MX104 Air Filter

Purpose
Action

For optimum cooling, verify the condition of the air filter.

Regularly inspect the air filter. A dirty air filter restricts airflow in the unit, producing a
negative effect on the ventilation of the chassis. The filter degrades over time. You
must replace the filter every 6 months.

CAUTION: Always keep the air filter in place while the router is operating.
Because the fans are very powerful, they could pull small bits of wire or
other materials into the router through the unfiltered air intake. This could
damage the router components.

Related
Documentation

Use spare filters within 1 year of manufacture. Check the date of manufacture printed
on the filter. Store spare air filters in a dark, cool, and dry place. Storing air filters at
higher temperatures, or where they can be exposed to ultraviolet (UV) radiation,
hydrocarbon emissions, or vapors from solvents, can significantly reduce their life.

Maintaining Cables That Connect to MX104 Network Ports

Purpose

188

For optimum router performance, verify the condition of the cables that connect to the
network ports.

Copyright 2015, Juniper Networks, Inc.

Chapter 25: Maintaining Components

Action

On a regular basis:

Use the cable management bracket to support cables and prevent cables from
dislodging or developing stress points.

Place excess cable out of the way in the cable management bracket. Do not allow
fastened loops of cable to dangle from the connector or cable management bracket,
because this stresses the cable at the fastening point. Putting fasteners on the loops
helps to maintain their shape.

Keep the cable connections clean and free of dust and other particles, which can cause
drops in the received power level. Always inspect cables, and clean them if necessary
before connecting an interface.

Label both ends of the cables to identify them.

The following guidelines apply specifically to fiber-optic cables:

When you unplug a fiber-optic cable, always place a rubber safety plug over the
transceiver on the faceplate and on the end of the cable.

Anchor fiber-optic cables to avoid stress on the connectors. Be sure to secure fiber-optic
cables so that they do not support their own weight as they hang to the floor. Never
let fiber-optic cable hang free from the connector.

Avoid bending fiber-optic cable beyond its bend radius. An arc smaller than a few
inches can damage the cable and cause problems that are difficult to diagnose.

Frequent plugging and unplugging of fiber-optic cable into and out of optical
instruments can cause damage to the instruments that is expensive to repair. Instead,
attach a short fiber extension to the optical equipment. Any wear and tear due to
frequent plugging and unplugging is then absorbed by the short fiber extension, which
is easy and inexpensive to replace.

Keep fiber-optic cable connections clean. Small microdeposits of oil and dust in the
canal of the transceiver or cable connector could cause loss of light, reducing signal
power and possibly causing intermittent problems with the optical connection.
To clean the transceivers, use an appropriate fiber-cleaning device, such as RIFOCS
Fiber Optic Adaptor Cleaning Wands (part number 946). Follow the directions for the
cleaning kit you use.

After you clean an optical transceiver, make sure that the connector tip of the fiber-optic
cable is clean. Use only an approved alcohol-free fiber-optic cable cleaning kit, such as
the Opptex Cletop-S Fiber Cleaner. Follow the directions for the cleaning kit you use.

The Junos OS command-line interface (CLI) is the primary tool for controlling and
troubleshooting router hardware, the Junos OS, routing protocols, and network
connectivity. CLI commands display information from routing tables, information specific
to routing protocols, and information about network connectivity derived from the ping
and traceroute utilities.
You enter CLI commands on one or more external management devices connected to
ports on the front panel.
For information about using the CLI to troubleshoot the Junos OS, see the appropriate
Junos OS configuration guide.

Front Panel LEDs

The front panel on the router contains LEDs that allow you to troubleshoot the router.
LEDs on the front panel include the following:

System LEDOne LED labeled SYS OK on the front panel indicates the status of the
router.

Alarm LEDsOne yellow and one red LED on the front panel indicate major and minor
alarms.

Preventing Electrostatic Discharge Damage to an MX104 Router

Many router hardware components are sensitive to damage from static electricity. Some
components can be impaired by voltages as low as 30 V. You can easily generate
potentially damaging static voltages whenever you handle plastic or foam packing
material or if you move components across plastic or carpets. Observe the following
guidelines to minimize the potential for electrostatic discharge (ESD) damage, which
can cause intermittent or complete component failures:

Always use an ESD wrist strap or ankle strap, and make sure that it is in direct contact
with your skin.

CAUTION: For safety, periodically check the resistance value of the ESD
strap. The measurement should be in the range of 1 to 10 Mohms.

When handling any component that is removed from the chassis, make sure the
equipment end of your ESD strap is attached to the electrostatic discharge point on
the chassis (see Figure 69 on page 218).

Avoid contact between the component and your clothing. ESD voltages emitted from
clothing can still damage components.

When removing or installing a component, always place it component side up on an

antistatic surface, in an antistatic card rack, or in an electrostatic bag (see
Figure 70 on page 219). If you are returning a component, place it in an electrostatic bag
before packing it.

Fire Suppression Equipment on page 221

General Fire Safety Requirements

In the event of a fire emergency involving network devices, the safety of people is the
primary concern. Establish procedures for protecting people in a fire emergency, provide
safety training, and properly provision fire-control equipment and fire extinguishers.
In addition, establish procedures to protect your equipment in a fire emergency. Juniper
Networks products should be installed in an environment suitable for electronic
equipment. We recommend that fire suppression equipment be available in the event
of a fire in the vicinity of the equipment, and that you observe all local fire, safety, and
electrical codes and ordinances when installing and operating your equipment.

Fire Suppression
In the event of an electrical hazard or an electrical fire, first turn power off to the equipment
at the source. Then use a Type C fire extinguisher, which uses noncorrosive fire retardants,
to extinguish the fire.

Fire Suppression Equipment

Type C fire extinguishers, which use noncorrosive fire retardants such as carbon dioxide
(CO ) and Halotron, are most effective for suppressing electrical fires. Type C fire
2

extinguishers displace the oxygen from the point of combustion to eliminate the fire. For
extinguishing fire on or around equipment that draws air from the environment for cooling,
use this type of inert oxygen displacement extinguisher instead of an extinguisher that
leave residues on equipment.
Do not use multipurpose Type ABC chemical fire extinguishers (dry chemical fire
extinguishers) near Juniper Networks devices. The primary ingredient in these fire
extinguishers is monoammonium phosphate, which is very sticky and difficult to clean.

Copyright 2015, Juniper Networks, Inc.

221

MX104 3D Universal Edge Router Hardware Guide

In addition, in minute amounts of moisture, monoammonium phosphate can become

highly corrosive and corrodes most metals.
Any equipment in a room in which a chemical fire extinguisher has been discharged is
subject to premature failure and unreliable operation. The equipment is considered to
be irreparably damaged.

NOTE: To keep warranties effective, do not use a dry chemical fire extinguisher
to control a fire at or near a Juniper Networks device. If a dry chemical fire
extinguisher is used, the unit is no longer eligible for coverage under a service
agreement.

We recommend that you dispose of any irreparably damaged equipment in an

environmentally responsible manner.

MX104 AC Power Electrical Safety Guidelines and Warnings

The following electrical safety guidelines apply to an AC-powered router:

You can order three-wire electrical cords with a grounding-type plug that fits only a
grounding-type power outlet. Do not circumvent this safety feature. Equipment
grounding should comply with local and national electrical codes.

Each AC power supply has one AC appliance inlet. Each inlet requires a dedicated AC
power feed and a dedicated customer-site circuit breaker. For the recommended circuit
breaker rating, see MX104 AC Power Specifications on page 101.

WARNING: The router is pluggable type A equipment installed in a

restricted-access location.

The power cord serves as the main disconnecting device for the AC-powered device.
The socket outlet must be near the AC-powered device and be easily accessible.

The cores in the main lead are colored in accordance with the following code:

Green and yellowEarth

BlueNeutral

BrownLive

When a router is equipped with two AC power supplies, you must unplug both power
cords (one for each power supply) to completely disconnect power to the router.

WARNING: The attached power cable is only for this product. Do not use the
cable for another product.

MX104 DC Power Electrical Safety Guidelines

The following electrical safety guidelines apply to a DC-powered router:

A DC-powered router is equipped with a DC terminal block that is rated for the power
requirements of a maximally configured router. To supply sufficient power, terminate
the DC input wiring on a facility DC source capable of supplying the rating specified in
MX104 DC Power Specifications on page 105 per input for each power supply.
Incorporate an easily accessible disconnect device into the facility wiring. In the United
States and Canada, the 48-VDC facility should be equipped with a circuit breaker rated
a minimum of 125 percent of the power provisioned for the input in accordance with
the National Electrical Code in the US and the Canadian Electrical Code in Canada.

Run two wires from the circuit breaker box to a source of 24, 60, or 48 VDC. Use
appropriate gauge wire as specified in MX104 DC Power Cable and Lug Specifications
on page 106.

Be sure to connect the ground wire or conduit to a solid office (earth) ground. We
recommend a closed loop ring for terminating the ground conductor at the ground
stud.

A DC-powered router that is equipped with a DC terminal block is intended only for
installation in a restricted access location. In the United States, a restricted access
area is one in accordance with Articles 110-16, 110-17, and 110-18 of the National Electrical
Code ANSI/NFPA 70.

NOTE: Primary overcurrent protection is provided by the building circuit

breaker. This breaker should protect against excess currents, short circuits,
and earth faults in accordance with NEC ANSI/NFPA70.

Related
Documentation

Ensure that the polarity of the DC input wiring is correct. Under certain conditions,
connections with reversed polarity might trip the primary circuit breaker or damage
the equipment.

For personal safety, connect the green and yellow wire to safety (earth) ground at both
the router and the supply side of the DC wiring.

The marked input voltage for a DC-powered router is the nominal voltage associated
with the battery circuit, and any higher voltages are only to be associated with float
voltages for the charging function.

Because the router is a positive ground system, you must connect the positive lead to
the terminal labeled +, the negative lead to the terminal labeled , and the earth ground
to the chassis grounding points.

Varoitus Jos sikeellinen johdin on tarpeen, kyt hyvksytty johdinliitnt,
esimerkiksi suljettua silmukkaa tai kourumaista liitnt, jossa on ylspin
knnetyt kiinnityskorvat. Tllaisten liitntjen tulee olla kooltaan johtimiin
sopivia ja niiden tulee puristaa yhteen sek eristeen ett johdinosan.
Attention Quand des fils torsads sont ncessaires, utiliser des douilles
terminales homologues telles que celles circuit ferm ou du type plage
ouverte avec cosses rebrousses. Ces douilles terminales doivent tre de la
taille qui convient aux fils et doivent tre refermes sur la gaine isolante et
sur le conducteur.
Warnung Wenn Litzenverdrahtung erforderlich ist, sind zugelassene
Verdrahtungsabschlsse, z.B. Ringoesen oder gabelfrmige Kabelschuhe
mit nach oben gerichteten Enden zu verwenden. Diese Abschlsse sollten
die angemessene Gre fr die Drhte haben und sowohl die Isolierung als
auch den Leiter festklemmen.
Avvertenza Quando occorre usare trecce, usare connettori omologati, come
quelli a occhiello o a forcella con linguette rivolte verso l'alto. I connettori
devono avere la misura adatta per il cablaggio e devono serrare sia l'isolante
che il conduttore.
Advarsel Hvis det er ndvendig med flertrdede ledninger, brukes godkjente
ledningsavslutninger, som for eksempel lukket slyfe eller spadetype med
oppoverbyde kabelsko. Disse avslutningene skal ha riktig strrelse i forhold
til ledningene, og skal klemme sammen bde isolasjonen og lederen.
Aviso Quando forem requeridas montagens de instalao elctrica de cabo
torcido, use terminaes de cabo aprovadas, tais como, terminaes de cabo
em circuito fechado e planas com terminais de orelha voltados para cima.
Estas terminaes de cabo devero ser do tamanho apropriado para os
respectivos cabos, e devero prender simultaneamente o isolamento e o fio
condutor.
Atencin! Cuando se necesite hilo trenzado, utilizar terminales para cables
homologados, tales como las de tipo "bucle cerrado" o "espada", con las

Distance Limitations for Signaling

Improperly installed wires can emit radio interference. In addition, the potential for damage
from lightning strikes increases if wires exceed recommended distances or if wires pass
between buildings. The electromagnetic pulse (EMP) caused by lightning can damage
unshielded conductors and destroy electronic devices. If your site has previously
experienced such problems, you might want to consult experts in electrical surge
suppression and shielding.

Radio Frequency Interference

You can reduce or eliminate the emission of radio frequency interference (RFI) from your
site wiring by using twisted-pair cable with a good distribution of grounding conductors.
If you must exceed the recommended distances, use a high-quality twisted-pair cable
with one ground conductor for each data signal when applicable.

Electromagnetic Compatibility
If your site is susceptible to problems with electromagnetic compatibility (EMC),
particularly from lightning or radio transmitters, you might want to seek expert advice.
Strong sources of electromagnetic interference (EMI) can destroy the signal drivers and
receivers in the router and conduct power surges over the lines into the equipment,
resulting in an electrical hazard. It is particularly important to provide a properly grounded
and shielded environment and to use electrical surge-suppression devices.

WARNING: The intrabuilding port(s) of the equipment or subassembly is

suitable for connection to intrabuilding or unexposed wiring or cabling only.
The intrabuilding port(s) of the equipment or subassembly MUST NOT be

metallically connected to interfaces that connect to the OSP or its wiring.

These interfaces are designed for use as intrabuilding interfaces only (Type
2 or Type 4 ports as described in GR-1089-CORE, Issue 4) and require isolation
from the exposed OSP cabling. The addition of primary protectors is not
sufficient protection to connect these interfaces metallically to OSP wiring.

CAUTION: To comply with intrabuilding lightning and surge requirements,

intrabuilding wiring must be shielded, and the shield for the wiring must be
grounded at both ends.
