Maintaining MX2020 Packet Forwarding Engine Components
Maintaining MX2020 MPCs
Purpose
The router can have up to 20 Modular Port Concentrators (MPCs) mounted vertically in the MPC card cage at the front of the chassis. For optimum router performance, verify the condition of the MPCs.
Action
On a regular basis:
Check the LEDs on the craft interface directly above each MPC slot. The green LED labeled OK lights steadily when a MPC is functioning normally.
Check the OK/FAIL LED on the MPC. For more information, see MX Series Interface Module Reference. If the MPC detects a failure, the MPC sends an alarm message to the Routing Engine.
Check the status of installed MPCs by issuing the CLI
show chassis fpc
command to check the status of installed MPCs. As shown in the sample output, the value Online in the column labeled State indicates that the MPC is functioning normally:user@host> show chassis fpc Temp CPU Utilization (%) Memory Utilization (%) Slot State (C) Total Interrupt DRAM (MB) Heap Buffer 0 Empty 1 Empty 2 Empty 3 Empty 4 Online 28 11 0 2048 15 14 5 Empty 6 Empty 7 Online 30 8 0 2048 14 13 8 Online 29 10 0 2048 11 13 9 Online 31 12 0 2048 16 14 10 Present 28 11 Online 38 16 2 2048 16 14 12 Empty 13 Empty 14 Empty 15 Online 36 11 0 2048 15 14 16 Empty 17 Empty 18 Online 31 10 0 2048 18 13 19 Empty

Action
On a regular basis:

Maintaining Cables That Connect to MX2020 MPCs or MICs
Purpose
For optimum router performance, verify the condition of the cables that connect to the MPCs or MICs.
Action
On a regular basis:
Use an upper cable manager and a lower cable manager (shown in Figure 1) to support cables and prevent cables from dislodging or developing stress points.
Figure 1: Upper and Lower Cable Manager Cable RoutingNote:The MX2020 supports both standard and extended upper and lower cable management.
Place excess cable out of the way in the upper and lower cable managers. Do not allow fastened loops of cable to dangle from the connector or cable manager 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.
The following guidelines apply specifically to fiber-optic cables:
When you unplug a fiber-optic cable, always place a rubber safety plug over the transceiver on the faceplate and on the end of the cable.
Anchor fiber-optic cables to avoid stress on the connectors. Be sure to secure fiber-optic cables so that they do not support their own weight as they hang to the floor. Never let fiber-optic cable hang free from the connector.
Avoid bending fiber-optic cable beyond its bend radius. An arc smaller than a few inches can damage the cable and cause problems that are difficult to diagnose.
Frequent plugging and unplugging of fiber-optic cable into and out of optical instruments can cause damage to the instruments that is expensive to repair. Instead, attach a short fiber extension to the optical equipment. Any wear and tear due to frequent plugging and unplugging is then absorbed by the short fiber extension, which is easy and inexpensive to replace.
Keep fiber-optic cable connections clean. Small microdeposits of oil and dust in the canal of the transceiver or cable connector could cause loss of light, reducing signal power and possibly causing intermittent problems with the optical connection.
To clean the transceivers, use an appropriate fiber-cleaning device, such as RIFOCS Fiber Optic Adaptor Cleaning Wands (part number 946). Follow the directions for the cleaning kit you use.
After you clean an optical transceiver, make sure that the connector tip of the fiber-optic cable is clean. Use only an approved alcohol-free fiber-optic cable cleaning kit, such as the Opptex Cletop-S Fiber Cleaner. Follow the directions for the cleaning kit you use.
