For optimum performance, verify the condition of the PICs and PIC cables.
Check the LEDs on PIC faceplates. The meaning of the LED states differs for various
PICs. For more information, see the M10i Multiservice Edge 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.

Use the cable management system (shown in Figure 1 on page 6) to support cables
and prevent cables from dislodging or developing stress points. Place excess cable
out of the way in the cable management system. Do not allow fastened loops of cable
to dangle from the connector or cable management system, because this stresses the
cable at the fastening point. Putting fasteners on the loops helps to maintain their
shape.
