Upgrade Procedures for RPM-PR Cards
Tip To simplify runtime software updates, copy the runtime file in the E:RPM 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 IOS on each card to recognize the new
filename.
Upgrading RPM-PR 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-PR card using the “Upgrading RPM-PR Runtime Software for
Non-Redundant Cards” procedure in the next section.
To upgrade the RPM-PR runtime software for 1:N redundancy, use the following procedure.
Step 1 Copy the new runtime software file for the RPM-PR card to the switch (E:RPM) as described in the
“Copying Software Files to the Switch” section, which appears earlier in this appendix.
Step 2 If you are using a generic filename for your runtime images, copy the file on the PXM45 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-PR 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-PR card to update.
pop20two.7.PXM.a > cc 9

Router>
The switch displays the 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, 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 6 Enter Enable mode for the router.
