ROM Monitor Overview
Manually Halting the Initialization Process During System Reload
To force the RSP card 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
TYPE 'Send Break'to abort
This message usually appears during the first 20 seconds of system startup. Press the Ctrl-C key combination
immediately. It may be necessary to press the Ctrl-C keys repeatedly during this time to ensure that the
initialization process stops and the system enters ROM Monitor mode. This ends your Telnet session to the
console or auxiliary port.
This operation can be performed only from a terminal directly connected to the RSP card console port. For
more information, see the "Connecting and Communicating with the Router" section in Cisco ASR 9000 Series
Aggregation Services Router Getting Started Guide.
When the RSP card is placed in ROMMON, it switches over to the standby RSP card, which can then
Note
also be placed in ROMMON. Repeat this process for both RSP cards.
