380 ! Replacing the PCG
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.
Action To replace a PCG, see “Return the Failed Component” on page 86, or the procedure
to return a field-replaceable unit in the M40e or M160 router hardware guide.
