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 cable 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.
