Prerequisite

Place a foam pad or cardboard on the ground to protect the housing of the RRU from damage before the binding. Do not stand the RRU upright because the load-bearing capacity of the RF ports at the RRU bottom is low.

CAUTION

Procedure

Step 1 Bind the RRU and mounting kits properly using a lifting sling, as shown in Figure 6-39.

When installed on a tower, only one RRU can be installed in standard mode or reverse mode, and two RRUs can be installed on a pole in back-to-back mode. RRUs cannot be installed on the side, and the brackets for more than two RRUs cannot be combined.

Figure 6-39 Binding mounting kits for the RRU

If a cable listed below is not required, skip the routing requirements of the cable.

General Cabling Requirements

The bending radius of the cables must meet the following specifications:

l The bending radius of the 7/8'' feeder must be more than 250 mm (9.84 in.), and the bending

radius of the 5/4'' feeder must be more than 380 mm (14.96 in.).

l The bending radius of the 1/4'' jumper must be more than 35 mm (1.38 in.). The bending

radius of the super-flexible 1/2'' jumper must be more than 50 mm (1.97 in.), and the bending radius of the ordinary 1/2'' jumper must be more than 127 mm (5 in.).

cable.

l The bending radius of the E1/T1 cable must be at least five times the diameter of the cable.

l The bending radius of the signal cable must be at least five times the diameter of the cable.

The cables must be bound as follows:

l Different types of cables must be separately routed and cannot be entangled.

l The cables must be bound tightly and neatly. The sheaths of the cables must not be damaged.

l The cable ties must face the same direction, and those at the same horizontal line must be

in a straight line. Extra length of cable ties must be cut.

l Labels or nameplates must be attached to the cables after they are installed.

The cables must be routed as follows:

in.) between every two cables.

l Different types of cables must be installed in an untangled and orderly fashion.

l Different types of cables must be routed in parallel or separated by special objects.

Special Cabling Requirements

Cabling requirements for power cables are as follows:

l -48 V power cables must be bound together.

l +24 V power cables must be bound together.

l Power cables, transmission cables, and signal cables are routed separately.

l Multiple power cables must be bound when routed.

Issue 05 (2011-10-20) Huawei Proprietary and Confidential

RRU3232 Installation Guide 7 Installing RRU Cables

l If the length of power cables is insufficient, replace the cables rather than adding connectors

or soldering joints to lengthen the cables.

Cabling requirements for PGND cables are as follows:

l PGND cables for the base station must be connected to the same ground bar.

l PGND cables must be buried in the ground or routed indoors. They should not be routed

overhead before they are led into the equipment room.

l The exterior of the coaxial wire and the shield layer of the shielded cable must have proper

electrical contact with the metal surface of the equipment to which they are connected.

l PGND cables and signal cables must be installed in an untangled and orderly fashion. A

certain distance must be reserved between them to prevent interference from each other.

l Other devices must not be used for electrical connections of the PGND cables.

l All the metal parts in the housing of the equipment must be reliably connected to the ground

terminal.

Cabling requirements for E1 cables are as follows:

l E1 cables must not cross power cables, PGND cables, or RF cables when routed. If

transmission cables are routed with power cables, PGND cables, or RF cables in parallel, the spacing between them must be greater than 30 mm (1.18 in.).

l E1 cables are routed straightly and bound neatly with cable ties.

l Sufficient slack is provided in E1 cables at turns.

Cabling requirements for fiber optic cables are as follows:

l Do not stretch, step on, or place heavy objects on fiber optic cables. Keep the cables away

from sharp objects.

l When fiber optic cables are routed, the extra length of the cables must be coiled around

special devices, such as a fiber coiler.

l When coiling fiber optic cables, apply even strength. Do not bend the cables with force.

l Vacant optical connectors must be covered with dustproof caps.
