Graceful RPM Boot and Runtime Software Upgrades

The RPM cards support graceful boot software upgrades when 1:N redundancy is established in the
switch between RPM cards. Boot software is generally upgraded less often than runtime software, so be
sure to compare the recommended boot software version with the boot software running on your RPM
cards before starting an upgrade. The correct boot software might already be installed.
Note In this document, the general term "RPM" refers to 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.
The following quickstart procedure describes how to upgrade boot and runtime software in one operation
on redundant RPM cards.
Note Redundancy must be established before you use this procedure. If redundancy has not been configured
between two RPM cards, upgrade each RPM card using the procedure in the
Software
"Establishing Redundancy Between RPM
Operation."

Purpose
Copy the boot and runtime files you want to use to the switch
(C:FW).
See the "Copying Software Files to the
this appendix.
Optional: Copy and rename the runtime file to a generic name for
easy updates.
See the "Upgrading RPM Runtime
chapter.
Note If you have already configured the RPM to use a generic
name and you perform this step, you can skip Steps 11
through 18.
Establish a CLI session with the active PXM card using a user
name at any access level.
Select the slot in which the primary RPM card is installed.
Enter Enable mode for the router.
Verify router access to the PXM hard disk and the boot upgrade
software.
Display current contents of bootflash.
Copy the upgrade boot software to flash. For example:
copy x:rpm-boot-mz_002.001.060.000 bootflash:
