Upgrade Procedures for RPM-PR Cards
Step 14 Switch to the secondary card using the softswitch command as follows:
8850_LA.8.PXM.a > softswitch <fromSlot> <toSlot>
Replace <fromSlot> with the slot number of the primary card. Replace <toSlot> with the slot number of
the secondary card.
This step makes the secondary card active and resets the primary RPM-PR card. When the Primary card
resets, it loads the upgraded software.
Step 15 Switch back to the primary card using the softswitch command as follows:
8850_LA.8.PXM.a > softswitch <fromSlot> <toSlot>
Replace <fromSlot> with the slot number of the secondary card. Replace <toSlot> with the slot
number of the primary card.
This step makes the primary card active and resets the secondary RPM-PR card. When the reset is
complete, the secondary card is ready to run the upgraded software.
Step 16 To verify that the router reboot is complete, enter the dspcds or dspcd <slot> commands. The reboot is
complete when the card state displays as Active. Another way to verify router operation is to use the cc
slot command. If you can access the router from the switch prompt, the router reboot is complete.
Step 17 If there are other primary cards with redundant (secondary) cards, repeat this procedure for each primary
card.
Upgrading RPM-PR Runtime Software for Non-Redundant Cards
To upgrade the RPM-PR runtime software for non- redundant cards, 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 Use the cc command to select the RPM-PR card to update.
pop20two.7.PXM.a > cc 9
(session redirected)
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.
