Intra-Building Lightning Protection

Shielded cables which are grounded at both ends are required to be used on the 10/100 Ethernet port in order to be in compliance with requirement R4-11 in GR-1089-Core for a Central Office environment. This is not a requirement for customer premise installations.

Warning

To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage

 

(TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports

 

both use RJ-45 connectors. Use caution when connecting cables.

 

 

To identify the RJ-45 cable type, hold the two ends of the cable next to each other so you can see the colored wires inside the ends. The straight-through wire type has colored wires in the same sequence at both ends. In the crossover wire type, the first colored wire at the far left is the third colored wire at the other end. The second colored wire at the far left is the sixth colored wire at the other end.

Attach RJ-45 Ethernet cables to the appropriate connector.
