30 PA-5EFL Ethernet 10BASE-FL Port Adapter Installation and Conﬁguration

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.
