100Base-FX Line Cards (Multimode Fiber-optic Cable)
The 100Base-FX line cards provide the same features as the 10/100Base-TX line card but
use multimode fiber-optic cable (MMF) to connect to the network. The MMF line cards are
available in 4 MB and 16 MB versions.

Description
When lit, this amber LED on the left side of the line card
indicates that the line card is offline (powered off) and is ready
for hot swap.
The Offline LED also is lit briefly during a reboot or reset of the
SSR and goes out as soon as the Control Module discovers and
properly initializes the line card.
When lit, this green LED indicates that the line card is online
and is ready to receive, process, and send packets if configured
to do so.
Each port has two LEDs on its connector. The green LED on
the left side of the connector indicates the link status. When
this LED is lit, the port hardware is detecting that a cable is
plugged into the port and the port has established
communication with the device at the other end.
The amber LED on the right side of each port connector flashes
each time the port's transceiver sends or receives packets.
