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:
