Switch Cooling Requirements

Switch Cooling Requirements

Wherever the switch is located, be sure to pay close attention to switch cooling
requirements. The location should be well ventilated and provide unrestricted air
flow at the front, back, and sides of the switch. If the air flow is insufficient, it may
cause the switch to overheat and possibly fail.

The ECS4210-12T is designed to be fanless and relies on convective cooling. The

following figure shows the convective cool air intake and hot air exhaust airflow
into and out from the ECS4210-12T switch side panel vents.

Figure 12: ECS4210-12T Switch Cooling

Rack Cooling When mounting the switch in an enclosed rack or cabinet, be sure to check the
following guidelines to prevent overheating:

◆ Make sure that enough cool air can flow into the enclosure for the equipment it
contains.

◆ Check that the rack or cabinet allows the hot air to exit the enclosure (normally
from the top) without circulating back into equipment.

◆ If the enclosure has sides or doors with ventilation holes, make sure they are
not blocked by cables or other obstructions.

◆ Route cables within the rack or cabinet to maximize the air flow.

◆ When possible, do not completely fill the rack or cabinet with equipment, allow
some unused space within the enclosure for better air flow.

Cable Labeling and Connection Records

Cable Labeling and Connection Records

When planning a network installation, it is essential to label the opposing ends of
cables and to record where each cable is connected. Doing so will enable you to
easily locate inter-connected devices, isolate faults and change your topology
without need for unnecessary time consumption.

To best manage the physical implementations of your network, follow these

guidelines:

◆ Clearly label the opposing ends of each cable.

◆ Using your building’s floor plans, draw a map of the location of all network-
connected equipment. For each piece of equipment, identify the devices to
which it is connected.

◆ Note the length of each cable and the maximum cable length supported by the
switch ports.

◆ For ease of understanding, use a location-based key when assigning prefixes to

your cable labeling.

◆ Use sequential numbers for cables that originate from the same equipment.

◆ Differentiate between racks by naming accordingly.

◆ Label each separate piece of equipment.

◆ Display a copy of your equipment map, including meanings of all abbreviations

at each equipment rack.

1000BASE-T Cable Requirements

All Category 5 UTP cables that are used for 100BASE-TX connections should also
work for 1000BASE-T, providing that all four wire pairs are connected. However, it is
recommended that for all critical connections, or any new cable installations,
Category 5e (enhanced Category 5) or Category 6 cable should be used. The
Category 5e and 6 specifications include test parameters that are only
recommendations for Category 5. Therefore, the first step in preparing existing
Category 5 cabling for running 1000BASE-T is a simple test of the cable installation
to be sure that it complies with the IEEE 802.3-2008 standards.

Connection Procedure Follow these steps to connect cables to 1000BASE-T RJ-45 twisted-pair copper
ports.

1. Attach one end of a twisted-pair cable segment to the device’s RJ-45 connector.

Figure 19: Making Twisted-Pair Connections

1 1000BASE-T RJ-45 Port 2 Category 5,5e or 6 Cable

2. Attach the other end to an available port on the switch.

Make sure each twisted pair cable does not exceed 100 meters (328 ft) in
length.

3. As each connection is made, the Link LED (on the switch) corresponding to
each port will turn on green to indicate that the connection is valid.

How to Connect to SFP Fiber Optic Ports

The switch provides four slots for SFP-compliant fiber-optic transceivers.

Note that all 1000BASE fiber optic ports operate at 1 Gbps full duplex.

Note: The length of fiber optic cable for a single switched link should not exceed
the relevant standards specified in this section. However, power budget constraints
should also be considered when calculating the maximum fiber optic cable length
for a particular link.
Note: Maximum distances may vary for different SFP vendors.

Connection Procedure Follow these steps to connect cables to SFP transceiver ports.

Warning: This switch uses lasers to transmit signals over fiber optic cable. The
lasers are compliant with the requirements of a Class 1 Laser Product and are
inherently eye safe in normal operation. However, you should never look directly at
a transmit port when it is powered on.
Warning: When selecting a fiber SFP device, considering safety, please make sure
that it can function at a temperature that is not less than the recommended
maximum operational temperature of the product. You must also use an approved
Laser Class 1 SFP transceiver.

How to Connect to SFP Fiber Optic Ports

1. Remove and keep the fiber port’s rubber plug. When not connected to a fiber
cable, the rubber plug should be replaced to protect the optics.

2. Check that the fiber terminators are clean. You can clean the cable plugs by
wiping them gently with a clean tissue or cotton ball moistened with a little
ethanol. Dirty fiber terminators on fiber optic cables will impair the quality of
the light transmitted through the cable and lead to degraded performance on
the port.

3. Connect one end of the cable to the SFP port on the switch and the other end
to the SFP port on the other device. Since SFP connectors are keyed, the cable
can be attached in only one orientation.

Figure 20: Making a Connection to an SFP Port

1 SFP Transceiver Port 2 SFP Fiber Optic Cable

4. As a connection is made, check the Link LED on the switch to be sure that the
connection is valid.

Note: Be sure to secure cables properly and route them away from the switch
without exceeding the minimum bending radius for fiber cables (typically a few
inches). Use cable ties to bundle cables together and secure coiled loops of excess
cable. Do not let cables hang free supporting their own weight or pull in any way
that puts stress on the connectors.

 A Troubleshooting

Diagnosing LED Indicators

Table 10: Troubleshooting Chart
Symptom Action

Pwr LED is Off ◆ Check connections between the switch, the power cord, and the AC
power outlet.
◆ Check the AC power outlet is supplying 110-240 VAC.
◆ Contact your dealer for assistance.

Diag LED is blinking ◆ Power cycle the switch to try and clear the condition.
Amber ◆ If the condition does not clear, contact your dealer for assistance.

Link/Act LED is Off ◆ Verify that the switch and attached device are powered on.
◆ Check the cable connectors are firmly plugged into both the switch
and corresponding device.
◆ If the switch is installed in a rack, check the connections to the
punch-down block and patch panel.
◆ Verify that the proper cable type is used and its length does not
exceed specified limits.
◆ Check the attached device and cable connections for possible
defects. Replace the defective cable if necessary.

System Self-Diagnostic Test Failure

If the Diag LED indicates a failure of the system power-on-self-test (POST), you can
use a console connection to view the POST results. The POST results may indicate a
failed component or help troubleshoot the problem. For more information on
connecting to the console port and using the CLI, refer to the CLI Reference Guide.

Note a POST failure normally indicates a serious hardware fault that cannot be

 Chapter A | Troubleshooting
Power and Cooling Problems

Power and Cooling Problems

If a power indicator does not turn on when the power cord is plugged in, you may
have a problem with the power outlet, power cord, or internal power supply.
However, if the switch shuts down after operating for a continuous period, check
for loose power connections, power losses or surges at the power outlet. If you still
cannot isolate the problem, the internal power supply may be defective.

Installation
Verify that all system components have been properly installed. If one or more
components appear to be malfunctioning (such as the power cord or network
cabling), test them in an alternate environment where you are sure that all the
other components are functioning properly.

In-Band Access
You can access the management agent in the switch through a connection to any
port using Telnet, a web browser, or other network management software tools.
However, you must first configure the switch with a valid IP address, subnet mask,
and default gateway. If you have trouble establishing a link to the management
agent, check to see if you have a valid network connection. Then verify that you
entered the correct IP address. Also, be sure the switch port has not been disabled.
If it has not been disabled, then check the network cabling that connects your
remote location to the switch.
