Maintain FPCs and PICs

The router can have up to eight Flexible PIC Concentrators (FPCs) mounted vertically in the FPC card cage at the front of the chassis (see Figure 1). To maintain FPCs and the Physical Interface Cards (PICs) housed in them, perform the following procedures on a regular basis:

• Check the LCD on the craft interface and the LEDs on the craft interface directly below each FPC slot. The green LED labeled OK lights steadily when an FPC is functioning normally. For more information, see FPC LEDs and Offline Button.
• 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 M20 and M40 Internet Routers PIC Guide. If the FPC that houses the PIC detects a PIC failure, the FPC informs the SCB, which in turn sends an alarm to the Routing Engine.
• Issue the CLI show chassis fpc command to check the status of installed FPCs. As shown in the sample output, the value Online in the column labeled State indicates that the FPC is functioning normally:

user@host> show chassis fpc

For more detailed output, add the detail option. The following example also specifies a slot number (0), which is optional:

user@host> show chassis fpc detail 0

• To check the status of a PIC, issue the CLI show chassis fpc pic-status command. The following example specifies an FPC slot number (5), which is optional. The PIC slots in an FPC are numbered from 0 (zero) through 3, top to bottom:

user@host> show chassis fpc pic-status 5

    Slot 5 Online

      PIC 0    1x OC-12 SONET, SMIR

      PIC 1    1x OC-12 ATM, MM

      PIC 2    1x OC-12 SONET, SMIR

      PIC 3    1x Tunnel
