For optimum router performance, verify the condition of the PICs and PIC cables.
On a regular basis:
Check the LEDs on PIC faceplates. A PIC LED lit green indicates the PIC is functioning
normally. The meaning of the LED states differs for various PICs. For more information,
see the interface module reference for your device. 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 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.
Keep the cable connections clean and free of dust and other particles, which can cause
drops in the received power level. Always inspect cables and clean them if necessary
before connecting an interface.
Label both ends of PIC cables to identify them.
