Purpose
Configure the BOOTLDR variable to specify the new boot
software.
Reorganize files in bootflash. The switch always attempts to load
the first bootable file in bootflash. If the BOOTLDR variable is
not set, the new boot software must be the first file listed in the
show flash: display. Copy files you want to save to the x:
directory and delete all files that appear before the new boot
software. Files are marked with the del command and actually
deleted with the squeeze flash: command.
Caution
Display the current runtime software filename.
Enter the router global configuration mode.
Remove the entire boot list. To remove a single file from the boot
list, include a filename. For example:
Router(config)# no boot system x:rpm-js-mz_122-4.T
Add the new router runtime image to the boot list. For example:
Router(config)# boot system x:rpm-js-mz_122-4.T
Configure the RPM card to store its configuration on the PXM
RPM-PR_ hard disk.
slot#
Note
Exit global configuration mode.
Save the new configuration.
Note
Verify the change in the runtime software filename.
This step makes the secondary card active and resets the primary
RPM card. When the primary card resets, it loads the upgraded
boot and runtime software.
Select the slot in which the secondary RPM card is installed.
Appendix A Downloading and Installing Software Upgrades
Verify that at least one valid boot or runtime image will
not be deleted. If all boot and runtime images are
deleted from bootflash, the RPM card must be returned
to the factory for repair.
This step only needs to be performed once. If this
command is already in the startup configuration file, you
do not need to enter it again.
If you omit this step, the RPM card will continue to use
the previous version of software.
