Placing the System in ROM Monitor Mode: Example
The following example shows how to place the primary RP in ROM monitor mode:

RP/0/RP0/CPU0:router(config)# config-register 0x0
RP/0/RP0/CPU0:router(config)# commit
RP/0/RP0/CPU0:router(config)# no config-register 0x0
RP/0/RP0/CPU0:router(config)# commit
RP/0/RP0/CPU0:router(config)# end
RP/0/RP0/CPU0:router# reload

Manually Halting the Initialization Process During System Reload
To force the router to stop loading and enter ROM monitor mode, press Ctrl-C when you see the
following message:
MBI validation sending request.
HIT CTRL-C to abort
This message usually appears during the first 20 seconds of system startup. It may be necessary to press
the Ctrl-C keys repeatedly during this time to ensure the initialization process stops and the system enters
ROMMON.
This operation can be performed only from a terminal directly connected to the router console port. See
the "Connecting and Communicating with the Router" section on page 2-1 for more information.
If a standby RP is installed in the system, repeat this process for both RPs. When the primary RP is
Note
placed in ROMMON, it fails over to the standby RP, which can then also be placed in ROMMON.
