Check the LEDs on PIC faceplates. Most PIC faceplates have an LED labeled
STATUS . Some PICs have additional LEDs, often one per port. The meaning of
the LED states differs for various PICs. For more information, see the M10i
Internet Router PIC Guide. If the FPC that houses the PIC detects a PIC failure,
the FPC generates an alarm message to be sent to the Routing Engine.
