Maintaining the PTX5000 PICs
Purpose For optimum performance, verify the condition of the PICs.
Action On a regular basis:
• Check the LEDs on PIC faceplates. The meaning of the LED states differs for various
PICs. For more information, see the PTX5000 Packet Transport Switch 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.
A PIC LED lit green indicates that the PIC is functioning normally.
• Issue the CLI show chassis fpc pic-status command. The PIC slots in an FPC are
numbered from 0 through 1, top to bottom.

Maintaining the PTX5000 PIC Cables
Purpose For optimum performance, verify the condition of the cables.
Action • Use the cable management system (shown in “PTX5000 Cable Management System”
on page 15) 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 the cables to identify them.
• When you unplug a fiber-optic cable from a transceiver, always place a rubber safety
plug over the transceiver on the faceplate and on the end of the cable.
• Anchor fiber-optic cable to avoid stress on the connectors. When attaching fiber to a
transceiver, be sure to secure the fiber so it is not supporting its own weight as it hangs
to the floor. Never let fiber-optic cable hang free from the connector.
