    Checklist for Monitoring FPCs

    Purpose

    You monitor and maintain Flexible PIC Concentrators (FPCs) to connect PICs to the rest of the router so that incoming packets are forwarded across the midplane to the appropriate destination ports. (See Table 1.)

    Action

    Monitor FPC Tasks

    Command or Action

    Checking the FPC Status

    1. Check FPC Status and Utilization

    show chassis fpc

    1. Check FPC Status and Uptime

    show chassis fpc detail fpc-slot

    1. (M40e, M160, M320, and T320 routers and T640 router only) Checking FPC Status and Temperature

    show chassis environment fpc fpc-slot

    1. Checking the FPC LED States

    Or, physically check the FPC LEDs on the Front Panel Module (FPM).

    Checking for FPC Alarms
    1. Replacing an FPC

    show chassis alarms

    1. Displaying FPC Error Messages in the System Log File

    show log messages | match “fpc| kernel | tnp”

    1. Displaying FPC Error Messages in the Chassis Daemon Log File

    show log chassisd | match fpc

    FPC Failure
    1. Document Events Prior to the FPC Failure

    Document a software upgrade, hardware upgrade, or reset.

    1. Checking the FPC Installation

    Check that the FPC is seated in the slot.

    Try to bring the FPC online.

    1. Checking the FPC Fuses

    The fuses for the and FPCs are located in the rear of the midplane behind the power supply in slot PEM0.

    1. Take the FPC Offline

    Press the offline button for approximately 3 seconds.

    1. Perform an FPC Swap Test

    Replace the FPC with one that you know works.

    1. Displaying the FPC Software Version Information

    show version brief

    1. Display the FPC Hardware Information

    show chassis hardware

    1. Locating the FPC Serial Number ID Label
    • M20 Internet router—With the FPC in horizontal position, look on the top back right of the FPC.
    • M40 Internet router—With the FPC in vertical position, look on the back left side of the FPC.
    • M40e and M160 routers—With the FPC in vertical position, look on the center right side of the FPC.
    • For M320 routers—On an FPC3, the serial number ID label is located on the center of the right side. On an FPC2, the serial number label is located on the top PIC slot.
    • For T320 routers—On an FPC3, the serial number ID label is located on the center of the right side. On an FPC1 and FPC2, the serial number ID label is located near the top PIC slot.
    • For T640 routers—On an FPC3, the serial number label is located on the center of the right side. On an FPC2, the serial number label is located near the top PIC slot.
    Replace the FPC

    See Return the Failed Component. Follow the procedure in the appropriate router hardware guide.
