Figure 5-14 Connecting fronthaul Ethernet cable to iRU4438 iRRH
To connect fronthaul Ethernet cables:
1. Disconnect the ANT 3 RF
cable N-type connector from the OMNI 3 omni-
directional antenna to allow access to the front access panel.
2. Open the front access panel by unscrewing the four (4) M3 × 0.5 captive panel
sc
rews.
3. Remove the dust plug in the FR
ONTHAUL 1 Ethernet cable entry port and place
in spare parts inventory.
4. Access the cable clamp by removing cable clamp screw.
5. Route the Ethernet cable through the FR
ONTHAUL 1 Ethernet cable entry port.
6. Install the cable clamp onto the Ethernet cable di
rectly behind the RJ45 connector
plug.
7. Plug the RJ45 connector into the FRO
NTHAUL 1 port.
8. Secure the cable clamp and Ethernet cable assembly inside the iRU4438 iRRH
using t
he screw with washers removed in step 7
9. Tighten the cable clamp screw 28.3 in-lb (3.2 Nm) using a torque screwdriver.
