Connect Ethernet Cables

The router interface modules support RJ-45 and Ethernet SFP ports.

The RJ-45 port supports standard straight-through and crossover Category 5 unshielded twisted-pair (UTP)

cables. Cisco does not supply Category 5 UTP cables; these cables are available commercially.

To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,

Warning

connect the Gigabit Ethernet ports only to intra-building or unexposed wiring or cable. The intrabuilding

cable must be shielded and the shield must be grounded at both ends. The intra-building port(s) of the

equipment or subassembly must not be metallically connected to interfaces that connect to the OSP or its

wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as

described in GR-1089-CORE) and require isolation from the exposed OSP cabling. The addition of Primary

Protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring.

Follow these steps to connect a cable to a copper Gigabit Ethernet port:

SUMMARY STEPS

1. Confirm that the router is powered off.

2. Connect one end of the cable to the Gigabit Ethernet port on the router.

3. Connect the other end to the BTS patch or demarcation panel at your site.
