    Replace the PCG

    The PCGs are hot-pluggable. You can remove and replace them without powering down the router, but the routing functions of the system are interrupted when the PCG is removed.

    If both PCGs are installed and functioning normally, PCG0 is the master PCG and PCG1 is the backup by default.

    Removing the backup PCG does not affect the functioning of the router. Taking the master PCG offline causes the FPCs and SFMs to power down and restart, with the other PCG selected as master. The forwarding and routing functions are interrupted during this process.

    To replace a PCG, see Return the Failed Component or the procedure to return a field-replaceable unit in the M40e or M160 router hardware guide.
