Conﬁguring the 5EFL Interfaces

Attaching 5EFL Port Adapter Interface Cables

On a single 5EFL port adapter, you can use up to ﬁve pairs of ST ﬁber-optic connections. The 5EFL port adapter is an end station device and not a repeater. You must connect the 5EFL port adapter to a 10BASE-FL repeater or hub. ST-type ﬁber-optic cables are not available from Cisco Systems; they are available from outside commercial cable vendors.

Use the following procedure to connect ST ﬁber-optic cables to the 5EFL port adapter:

Step 1 Attach the RX multimode ﬁber-optic cable directly to the RX port on the 5EFL port adapter. (See Figure 13.)

Note Port adapters have a handle attached, but this handle is not shown to allow a full view of detail on each port adapter’s faceplate.

Step 2 Attach the TX multimode ﬁber-optic cable directly to the TX port on the 5EFL port adapter. (See Figure 13.)

To the appropriate TX and RX ports of the repeater, hub, DTE or other external 10BASE-FL equipment

Step 3 Connect a 5EFL RX port to the appropriate TX port of the repeater, hub, DTE or other external 10BASE-FL equipment.

Step 4 Connect a 5EFL TX port to the appropriate RX port of the repeater, hub, DTE or other external 10BASE-FL equipment.

Step 5 Repeat Steps 1 and 4 for each additional 5EFL interface connection you require.

This completes cable connection to the 5EFL port adapter.

If you installed a new 5EFL port adapter or if you want to change the conﬁguration of an existing interface, you must enter conﬁguration mode using the conﬁgure command. If you replaced a 5EFL port adapter that was previously conﬁgured, the system will recognize the new 5EFL interfaces and bring them up in their existing conﬁguration.
