Appendix A Downloading and Installing Software Upgrades
Upgrade Procedures for RPM-PR and RPM-XF Cards
When managing the bootflash, consider the following facts:
•
If the BOOTLDR variable is set and the RPM card is reset, the RPM card attempts to load the boot
software specified.
•
If the BOOTLDR variable is not set and the RPM card is reset, the RPM 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 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 card is installed.
•
If the image that RPM tries to load does not load, you can reset the RPM from the active PXM 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 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 PXM 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 card to the switch (C:FW) as described in the “
” section earlier in this appendix.
Tip
In the past, this guide recommended transferring files to the E:RPM directory. You can still do this
and reference the E:RPM directory by entering e: while in enable mode. However, storing boot and
runtime software in the E:RPM directory significantly increases the size of configuration files
created with the saveallcnf command. E:RPM is still used to store configuration files that should be
backed up.
Step 2
Establish a configuration session using any valid user name.
Step 3
Enter the cc command to select the RPM card to update.
pop20two.7.PXM.a >
cc 9
(session redirected)
Router>
The switch displays the Cisco IOS prompt for the router on the RPM 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 on the switch. For general Cisco IOS commands, examples are given to show
how to complete the task.
