Upgrading the ROMmon for a Router

Use this procedure to upgrade the ROMmon on a router:

Step 1 (Optional) Run the show platform command or the show rom-monitorslot command fon the router to see the current release numbers of ROMmon on the hardware. See the “Checking the Current ROMmon Version” section on page 5-2for information about interpreting the output of the command that you run.

Step 2 If the ROMmon image has not been copied onto the router, copy the PKG file that is made available as part of this ROMmon release onto the bootflash: or usb[0-1]: file system using the copy source-locationdestination-locationcommand. For example, if you are upgrading to Release 15.2(1r)S, copy the asr1000-rommon.152-1r.S.pkg file.

Step 3 Run the dir file-systemcommand to verify that the ROMmon file is copied into the specified directory.

Step 4 Run the upgrade rom-monitor filename location all command to begin the ROMmon image upgrade, where location is the path to the ROMmon file.

Caution Do not remove hardware, turn off power, or interrupt the router in any way during the ROMmon upgrade. Although the router should be able to recover from most interruptions during the ROMmon upgrade, certain scenarios may cause unpredictable problems.

Step 5 Messages pertaining to the upgrade are displayed on the console. After the display of these messages stops and the router prompt is available, run the reload command to reload the router.

Step 6 If autoboot has not been enabled by using the config-register 0x2102 command, run the boot filesystem:/file-locationcommand at the ROMmon prompt to boot the Cisco IOS XE image, where filesystem:/file-locationis the path to the consolidated package file. The ROMmon upgrade is not permanent for any piece of hardware until the Cisco IOS XE image is booted.

Step 7 Run the enable command at the user prompt to enter the privileged EXEC mode after the boot is complete.

Step 8 Run the show platform command or the show rom-monitorslot command to verify whether the ROMmon has been upgraded.
