5 Installing the iRU4438 iRRH
This section provides the procedure for installing the iRU4438 iRRH in remote
locations such as on towers, poles, masts, walls, roofs, or other structures utilizing a
universal mounting assembly.
Instructions for making connections to ext
ernal interfaces, cabling, grounding and
power are also provided.
5.1 Assembling cables
5.1.1 Verify Operator supplied 110/220 V ac power cable
The Operator supplies and pre-assembles the 110/220 V ac power connection cable.
We recommend using a 14 AWG, round, 2-wire with ground, shielded cable rated at
300 V minimum. The female plug (manufacturer's part no. BD-03BFFA-LL7001) for
connection at the iRU4438 iRRH end is also provided by the Operator. The connection
configuration for the supply side of the power cable is determined by site specific
requirements.
5.1.2 Verify Operator supplied fronthaul Ethernet cable
The CAT-5 Ethernet cable is supplied and pre-assembled by the Operator. A cable
gland may be pre-installed on the Ethernet cable, or may be installed on a CAT-5
cable, in the order shown in Figure 5-2. If the cable gland has a lock nut installed on
it, it must be removed before installing the cabl
e gland to the fronthaul entry port.
The cable gland screws directly into the fronthaul port on the bottom of the iRU4438.
A gasket seals the cable gland at the fronthaul port. The sealing nut is then hand-
tightened to complete the weatherproof seal.

5.1.3 Verify Operator supplied grounding cable
The operator pre-assembles the grounding cable prior to routing to the iRU4438 iRRH.
The grounding cable and ground bonding hardware is supplied by the Operator.
However, the grounding terminal lug is supplied with the iRU4438 iRRH.
