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. Take another shrink tube and pass the RF cable through.

6. Connect the other end of the RF cables to the external antenna.

7. Push the cold shrink tube to the antenna connector, and pull out the strip.

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

2. Lay the Ethernet cable along the wire groove and stretch out the wiring cavity from Ethernet (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 3-12.
