Appendix A Downloading and Installing Software Upgrades
Upgrade Procedures for RPM-PR Cards
When managing the bootflash, consider the following facts:
If the BOOTLDR variable is set and the RPM-PR card is reset, the RPM-PR card attempts to load
the boot software specified.
If the BOOTLDR variable is not set and the RPM-PR card is reset, the RPM-PR card tries to load
the first bootable image in bootflash. The first bootable image is the image that appears first in the
show flash: command display, and this is usually the oldest file in bootflash. Therefore, if you do
not use the BOOTLDR variable, the bootflash contents must be reorganized each time you upgrade
boot software.
The RPM-PR card will not attempt to boot from automatic configuration files, which are named
using the format auto_config_slotnn, where nn represents a slot in which an RPM-PR card is
installed.
If the image that RPM-PR tries to load does not load, you can reset the RPM-PR from the active
PXM45 card using the resetcd <slot> command.
Files are not removed from bootflash until the squeeze flash: command is entered. If you delete a
file and do not enter squeeze flash:, the RPM-PR card will still attempt to boot from the first image
it finds, whether it is marked for deletion or not.
Caution If all bootable images are deleted from bootflash, the card must be returned to the factory to be
reprogrammed.
If you do need to upgrade the boot software, you can copy the new boot file to the PXM45 disk, and then
copy it to the bootflash. The following procedure describes how to upgrade the boot software.
Step 1 Copy the new boot software file for the RPM-PR card to the switch (E:RPM) as described in the
Copying Software Files to the Switch” section earlier in this appendix.
Step 2 Establish a configuration session using any valid user name.
Step 3 Enter the cc command to select the RPM-PR card to update.

Router>
The switch displays the Cisco IOS prompt for the router on the RPM-PR card. From this point on, all
commands are Cisco IOS commands.
Note This procedure assumes that you are familiar with Cisco IOS commands (which is a topic that
is beyond the scope of this book). This procedure details only those commands that are unique
to setting up RPM-PR on the switch. For general Cisco IOS commands, examples are given to
show how to complete the task.
Step 4 Enter Enable mode for the router.
