Quickstart Procedures for Software Upgrades
Graceful RPM-PR Runtime Software Upgrades
The RPM-PR card supports graceful upgrades when 1:n redundancy is established in the switch between
RPM-PR cards.
The following quickstart procedure describes how to gracefully upgrade redundant RPM-PR cards.
Note Redundancy must be established before you use this procedure. If redundancy has not been configured
between two RPM-PR cards, upgrade each RPM-PR card as described in “Non-Graceful RPM-PR
Runtime Software Upgrades,” which appears later in this chapter. To add redundancy to an RPM-PR
card, see the “Establishing Redundancy Between Two RPM-PR Cards” section in Chapter 5, “Preparing
RPM-PR Cards for Operation.”

Repeat Steps 4 through 9 to move the upgraded boot software into
bootflash.
Step 13
switchredcd <secondarySlot>
<primarySlot>
This step makes the upgraded primary card active and resets the
secondary RPM-PR card. When the secondary card resets, it
loads the upgraded boot software from bootflash. Both primary
and secondary cards should now be using upgraded boot
software.
Step 14
— If there are other primary RPM-PR cards that need upgrading,
repeat the part of this procedure that upgrades the primary card,
then enter the switchredcd command once to reload the primary
card. Finally, enter the switchredcd command a second time to
make the upgraded primary card active.
