The information in this chapter applies to the Cisco AS5350XM and Cisco AS5400XM universal

run when the gateway is powered-up or reset. The ROM monitor can help you isolate or rule out
hardware problems encountered when installing your gateway. This appendix describes the following:

Entering the ROM Monitor Program

The ROM monitor diagnostics help initialize the processor hardware and boot the main operating system
software. If you set the software configuration register (bits 3, 2, 1, and 0) to zero, you can start the
gateway in the standalone ROM monitor. An example of the ROM monitor prompt follows:
rommon 1 >
To enable the Break key, and to default to booting at the ROM monitor while running the system
software, reset the configuration register to 0x0 by entering configuration mode, and enter the following
configuration command:
confreg 0x0
The new configuration register value, 0x0, takes effect after the gateway is rebooted with the reload
command. If you set the configuration to 0x0, you will have to manually boot the system from the
console each time you reload the gateway.
Break (system interrupt) is always enabled for 60 seconds after rebooting the system, regardless of
Timesaver
whether break is configured to be off by setting the configuration register. During the 60-second window,
you can break to the ROM monitor prompt.
