7 Replacing the BTS3702E Cables
Contact the local Huawei office to handle the faulty signal cables.
7.3 Replacing the Transmission Cables of the BTS3702E
The transmission cables of the BTS3702E are optical fibers and Ethernet cables.
7.3.1 Replacing the Ethernet Cables
The Ethernet cables are used to transmit the electric signals between the BTS3702E and the
ASN-GW, or transmit the electric signals between two cascading BTS3702Es. When the
Ethernet cables of the BTS3702C are faulty, you need to replace them.
7.3.2 Replacing the Optical Fibers
The optical fibers are used to transmit the optical signals between the BTS3702E and the ASN-
GW, or transmit the optical signals between two cascading BTS3702Es. When the optical fibers
of the BTS3702E are faulty, you need to replace them.

Context
Replacing the Ethernet cables between the BTS3702E and the ASN-GW interrupts all the
services carried by the BTS3702E. Replacing the cascading Ethernet cable between two
BTS3702Es interrupts all the BTS3702E services except the BTS3702E services between this
Ethernet cable and the ASN-GW.
Replacing the Ethernet cables involves removing the faulty cables and installing the new cables.
This operation takes about five minutes.
Take proper ESD prevention measures, for example, wear ESD wrist straps or gloves to prevent
boards, modules, and electronic components from being destroyed by static discharge from the
human body.
7-4
The quantity and types of the faulty Ethernet cables are confirmed, and new Ethernet cables
are ready.
The new cables are in good condition.
The installation position of the Ethernet cable is recorded.
The required tools and materials are ready. The tools and materials are the ESD wrist strap
or ESD gloves, and ESD box or bag.
