Example: Upgrading A Rommon - Cisco ASR 1001-X Hardware Installation Manual

Upgrading the ROMMON and CPLD
DETAILED STEPS
Step 1 (Optional) Run the show platform command or the show rom-monitor slot command to see the current release number
of ROMMON on the hardware.
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-location destination-location
command. For example, if you are upgrading to Release 15.4(2r)S, copy the asr1000-rommon.154-2r.S.pkg file.
Step 3 Run the dir file-system command 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.
Do not remove hardware, turn off power, or interrupt the router in any way during the ROMMON upgrade.
Caution
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.
If you change the configuration register setting through Cisco IOS after initiating a ROMMON upgrade, but
Note
before reloading the router, the configuration register setting will not be applied. Reload the router and allow
the ROMMON upgrade to be applied prior to changing the configuration register in Cisco IOS.
Step 6 If autoboot has not been enabled by using the config-register 0x2102 command, run the boot filesystem:/file-location
command at the ROMMON prompt to boot the Cisco IOS XE image, where filesystem:/file-location is 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.
If you enter the reset command twice when booting from the ROMMON prompt, the ROMMON upgrade will
Note
automatically fall back to the previous ROMMON image. The following message appears after you enter the
reset command the second time, and the earlier version of the ROMMON image is installed: Rommon upgrade
requestedMaximum upgrade attempts exceeded, continuing with old Rommon...
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-monitor slot command to verify whether the ROMMON has been
upgraded.
