Cisco 7200 Series and the 5EFL Port Adapter

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.

Connect ST fiber-optic cables to the 5EFL port adapter as follows:

Step 1 Attach the RX multimode fiber-optic cable directly to the RX port on the 5EFL port adapter. (See Figure 20.)

Note Port adapters have a handle attached, but it is not shown in Figure 20 to allow a full view of the 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 20.)

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.
