Installing the iRM4451
6-2 iRM4451 RRH Product Description and Installation Guide
To install ground terminal lug:
1. Cut a 6 AWG (4.11 mm) stranded grounding cable the appropriate length for the
iRM4451 installation.
2. Strip away insulation from one end to exp
ose 3/4 in (19 mm) of bare wire.
3. Crimp the dual-lug grounding terminal (supplied) to the cable using the special-
purpose cri
mp tool specified in Required tools on page 4-1 (or equivalent) as
directed by tool manufacturer instruction manual. Figure 6-12 shows an
assembled cable/lug assembly.

6.2 Routing pre-assembled power/GigE optical fronthaul/grounding
cables
This procedures provides instructions for routing the pre-assembled –48 V dc power
cable, the GigE optical fronthaul cable, and the grounding cable to the iRM4451
mounting location before assembling components.
To route cables:
1. Route the cables from the iRM4451 installation location to cable sources as shown
in
Figure 6-13.
