3.4.2 Connect RF Cables

WARNING:

Ensure the antenna is connected before powering up the eNB. The wireless

signal transmission power can cause bodily injury and damage to the eNB and RF power

amplifier devices.

1. Open the dust caps of the ANT0, ANT1, ANT2, and ANT3 interfaces.

2. Insert the RF cables into cold shrink tubes.

3. Connect RF cables to the ANT0, ANT1, ANT2, and ANT3 interfaces on the eNB, and tighten

them with a wrench to 12–15 in-lb or 1.4–1.7 NM torque.

NOTE: Antenna ports ANT0 and ANT1 connect to the primary cell (Pcell), or Cell 1.

Antenna ports ANT2 and ANT3 connect to the secondary cell (Scell), or Cell 2.

4. Push the cold shrink tube to the top joint, and pull out the strip.

5. Connect the other end of the RF cables to the external antennas, which also need

weatherproof protection.

1. Connect the Ethernet cable to the ETH interface in the wiring cavity.

2. Lay the Ethernet cable along the wire groove, and stretch out the wiring cavity from ETH

hole.

3. The Ethernet cable connects to the PoE interface of the PoE adapter.

4. The LAN interface of the PoE adaptor connects to a LAN switch or a router for maintenance

and backhaul.

NOTE: The PoE adaptor must be placed in the distribution box for waterproofing.

3.4.4.1 Pole Grounding

The purpose of pole grounding is to protect the equipment as much as possible from potential

damage of lightning overvoltage. However, the interfaces between the eNB and the outside world

mainly include power system, grounding system, antenna feeder and lightning receiving device,

and signal line. Therefore, any damage caused by lightning primarily comes from the voltage

difference between the equipment in the eNB and one or more of the four interfaces. The pole

grounding is shown in Figure 3-11.
