Step 8 Upgrade the ROM monitor image in RP1 using the upgrade rom-monitor slot

Upgrading the RP ROM Monitor Prior to Cisco IOS Release 12.0(24)S
If your RPs are running a software image prior to Cisco IOS Release 12.0(24)S,
you must use the following procedure to upgrade the RP ROM monitor, which
requires a reboot of the router.
In the following procedure, RP1 is initially the active RP and RP2 is the standby
RP.
Step 1 After you enter the configuration to load the new Cisco IOS software image,
reload the standby PRP (RP2) using the hw-module standby reload command.
Step 2 Switch over from the active PRP (RP1) to the standby PRP (RP2) using the
redundancy force-switchover command. Once RP2 becomes active, the line
cards will be reloaded.
