Installing the 12E/2FE Interface Cables

This chapter provides information for installing the 12E/2FE interface cables. The instructions that follow apply to all supported platforms.

Attaching 12E/2FE Port Adapter Interface Cables

On a single 12E/2FE port adapter, you can use up to 14 RJ-45 connections. (Category 3 and Category 5 UTP cables are not available from Cisco Systems; they are available from commercial cable vendors.)

Connect RJ-45 cables to the 12E/2FE port adapter as follows:

Note Use Category 3 unshielded twisted-pair (UTP) crossover cables when connecting 10-Mbps 12E/2FE interfaces (port 2 through port 13) to a hub. Use Category 3 UTP straight-through cables when connecting 10-Mbps 12E/2FE interfaces to an end station.

Use Category 5 UTP crossover cables when connecting 10/100-Mbps 12E/2FE interfaces (port 0 and port 1) to a hub. Use Category 5 UTP straight-through cables when connecting 10/100-Mbps 12E/2FE interfaces to an end station.

12E/2FE interfaces do not support VLAN trunking.

Step 1 Attach the cable directly to the RJ-45 port on the 12E/2FE port adapter. (See Figure 5-1.)

The 12E/2FE port adapter functions as a repeater or hub, and its interfaces connect to an end station or DTE.

Step 2 Attach the network end of your RJ-45 cable to your end station or DTE.

This completes the process for attaching 12E/2FE port adapter interface cables. Proceed to
