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.
Note The handles for the 12E/2FE port adapter are not shown in Figure 5-1 to allow a
full view of the port adapter’s faceplate.
