Quickstart Procedures for Software Upgrades

Graceful RPM Boot 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 redundant RPM cards.

Step 21

enable

password

dir x:

show flash:

copy filename bootflash:

dir bootflash:

config terminal

boot bootldr bootflash:filename

show bootvar

copy bootflash:filename

x:filename

del bootflash:filename

show flash:

squeeze flash:

Repeat Steps 5 through 10 to move the upgraded boot software

into bootflash.

Step 22

switchredcd <secondarySlot>

This step makes the upgraded primary card active and resets the

secondary RPM 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.

Note You do not need to upgrade runtime software on a

secondary card. When a secondary card goes active, it

loads the runtime software and configuration defined for

the primary card.

Step 23

— If there are other primary RPM 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.
