Removing and Installing Port Adapters
Connecting an ST Fiber-Optic Cable
On a single PA
adapter is an end station device and not a repeater; you must connect the PA-5EFL 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 PA-5EFL port adapter as follows:
Step 1
Attach the RX multimode fiber-optic cable directly to the RX port on the PA-5EFL. (See
Note
Step 2
Attach the TX multimode fiber-optic cable directly to the TX port on the PA-5EFL port adapter. (See

Step 3
Connect a PA-5EFLport adapter RX port to the appropriate TX port of the repeater, hub, DTE, or other
external 10Base-FL equipment.
Step 4
Connect a PA-5EFL port adapter 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 PA-5EFL interface connection you require.
This completes the procedure for attaching a multimode fiber-optic cable to the PA-5EFL port adapter.
