Plus, which are henceforth referred to as FlexiHopper 4E1, FlexiHopper and FlexiHop-
per Plus, respectively.
When the presented information refers to FlexiHopper 4E1, FlexiHopper and FlexiHop-
per Plus, the marking FlexiHopper (Plus) is used.

1.1.1.1 Precautions
The radiation emitted by the antenna is low-power radiation and does not exceed the
safety regulations. If the radio is operated without the antenna, the safety limit is
exceeded near the waveguide openings.

WARNING:
!
Do not look into an open waveguide while the equipment is operating. Damage to the
eye may result.

WARNING:
!
Do not connect or disconnect the Flexbus cable when the power is on. Switch off the
power using the manager software.

Before starting the installation, verify that you have the correct equipment (correct
outdoor unit frequency and subband, correct antenna) and that the equipment has not
been damaged during transport.

3.5 Installing a dual polarised antenna

Before you start
Check the coarse alignment before installing the antenna. See Coarse aligning an inte-
grated antenna.

Summary
A dual polarised antenna has two waveguide flanges, one for vertical and one for hori-
zontal polarisation. Dual polarised antenna is supplied with the blanking plate fitted to
the horizontal port. The blanking plate must be removed if horizontal polarisation port is
used. To remove the blanking plate, use a 2.5 mm Allen key on four M3 x 12 screws.
Radios cannot be integrated directly on dual polarised antenna.
Both radios are connected with flexible waveguides to the antenna. Dual polarised
antennas are installed in the same way as a single polarised antenna in a separate
installation.
Both radios may have their own alignment units. With clamps for dual alignment, a snap-
on-adapter can be installed on the alignment unit, in which case only one alignment unit
is needed for pole installation. This option is shown in Figure 10.

aligned to this station and must be sending a signal on the correct frequency.
The antenna is aligned on the basis of the monitoring voltage (AGC). The best signal is
achieved using the minimum value of AGC.

Grounding Installing Hardware

6 Grounding

6.1 Grounding FlexiHopper (Plus)

Before you start
g Follow local requirements for earthing (grounding). The principles and requirements
vary in different countries.

CAUTION:
!
Electrostatic discharge (ESD) may damage components in the plug-in units or other
units.
Wear an ESD wrist strap or use a corresponding method when handling the units, and
avoid touching the contacts and connector surfaces.

A 16 mm2 grounding cable is used in grounding the outdoor unit.

Summary
To ensure safe installation conditions for both personnel and equipment, the equipment
station must be grounded before installing the equipment. The purpose of protective
grounding is to keep the potential of the equipment at the same level as the potential of
the surrounding ground. This prevents generation of dangerous voltages between the
equipment and the ground. Because of the high locations of the radio and base station
equipment, equipment stations are particularly susceptible to lightning strokes.
Ground the equipment according to rules and regulations issued by the local authorities.
g For further information on protection against interference, see ITU-T K.27 (Bonding
configurations and earthing inside a telecommunication building) or corresponding
recommendations.

CAUTION:
!
To avoid damage to the equipment, ensure that all the equipment of an equipment
station is connected to the same earth (ground) potential.

The indoor unit does not require specific grounding arrangements.

Steps

1 Peel 15 mm of insulation from the tip of the grounding cable.

2 Connect the grounding cable to the grounding clamp of the outdoor unit and
tighten with a 13 mm spanner. The torque is 4 Nm.

8.5 Grounding FIU 19(E)

Before you start
Individual equipment components such as FIU 19(E) are grounded to equipment racks.
FIU 19(E) does not have separate grounding conductors between the indoor unit's
equipment cartridge and the rack body. The indoor unit is grounded to the rack body
through the mounting screws of the equipment cartridge.
The rack should be connected separately to the station's grounding conductor.
In FIU 19(E), positive supply voltage is normally grounded (externally). In Flexbus plug-
in unit, negative supply voltage is always grounded internally. Make sure the Flexbus
plug-in unit supply voltage is galvanically isolated from the FIU 19(E) supply voltage.

Aux Jumper Cable to the Alarm 2 connector.
Connect the FIU power cable to the FIU connector on the fan controller board. If only
one-battery input source is used for the outdoor case, the second FIU is connected to
the adjacent connector (see Figure 59). If two-battery input sources are used at site, the
other FIU 19E power cable is connected to either of the FIU B2 connectors on the fan
controller board (see Figure 59).
Connect the outdoor power cable coming from the DC source or Flexi BTS modules'
external output to the B1 connector. Remove the Molex connector from the fan controller
board and install it to the cable with two screws. There are + and - markings next to the
connectors on the fan controller board to guide how to install the connector of a cable.
In case two-battery input source is used, connect other outdoor power cable to the B2
connector on the fan controller board.
FIU 19E outdoor case requires a power supply input of -40.5 to -57 VDC instead of -40.5
to -72 VDC allowed for FIU 19E. Incorrect supply voltage may cause a failure in the fan
units of the outdoor case.
Two-battery input source configuration provides protection for DC source, thus it is rec-
ommended on sites where high availability is required.

Figure 93 Ethernet plug-in unit
The 2IU protected radio hop configurations are used to provide a reliable connection for
traditional E1 traffic. If EPIU is used in this configuration, both FIU 19Es have to be
equipped with EPIU. Additionally, a commercial 10/100 Base-T Ethernet switch/hub with
at least three Ethernet ports is needed to forward Ethernet traffic to EPIU on an active
FIU 19E. An IP router can be used as well.
g The Ethernet plug-in unit is not compatible with equipment providing power over the
Ethernet. Pins 4, 5, 7, and 8 on the Ethernet plug-in unit interfaces (ETH-1/ETH2)
are terminated to improve noise margin.

Steps

1 Plan the work in advance.

• Check which FB interface(s) are used for transmitting Ethernet traffic.
• Check which operating mode EPIU will be used in (channel separation, full switch of
capacity sharing mode).
• Check if 2OU protected mode is used, and if you are using Flexbus plug-in unit for
additional radios.
The three items listed above determine which interface (ETH-1 or ETH-2) needs to be
connected.

2 Connect CAT-5 Ethernet cables with RJ-45 connectors to the selected interfaces.
