Appendix A Downloading and Installing Software Upgrades
Upgrade Procedures for RPM-PR and RPM-XF Cards
To configure the RPM to load upgraded runtime software from the PXM hard disk, you need to do the
following:
• Copy the upgraded file to the PXM hard disk
• Update the boot system variable in the router startup-config file to load the new file.
• Reset the RPM card so that it loads the new file.
RPM cards can be configured for 1:N redundancy as well as for non-redundant configurations. The
procedures for both types of configuration are in the sections that follow.
Tip To simplify runtime software updates, copy the runtime file in the C:FW directory and rename it to
a generic name such as rpm-js-mz. The production runtime filenames have version numbers
appended to them, but you can change this. This approach allows you to perform future upgrades by
copying the file to the hard disk, renaming a copy of the file to your generic name, and resetting each
card. The approach eliminates the need to reconfigure Cisco IOS commands on each card to
recognize the new filename.
Upgrading RPM Runtime Software for 1:N Redundancy
Redundancy must be established before you use the procedure in this section. If redundancy has not been
established, upgrade each RPM card using the procedure in the next section, “Upgrading Without
Redundancy”.
Note In this document, the general term “RPM” refers for both the RPM-PR and RPM-XF cards. If a step or
procedure is specific to only one of the RPM cards, it will be called out in the text.
To upgrade the RPM runtime software for 1:N redundancy, use the following procedure.
Step 1 Copy the new runtime software file for the RPM card to the switch (C:FW) as described in the “Copying
Software Files to the Switch” section earlier in this appendix.
Step 2 If you are using a generic filename for your runtime images, copy the file on the PXM hard disk and
rename the copy. For example:
8850_LA.8.PXM.a > copy rpm-js-mz_122-4.T rpm-js-mz
Step 3 Establish a configuration session using any valid user name.
Step 4 If your RPM is already configured to use a file with a generic name, skip to Step 13.
Step 5 Enter the cc command to select the RPM card to update.
pop20two.7.PXM.a > cc 9

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.
