Performing a Fast Software Upgrade
The fast software upgrade (FSU) procedure supported by RPR allows you to upgrade the Cisco IOS
image on the supervisor engines without reloading the system.
Note If you are performing a first-time upgrade to RPR from EHSA, you must reload both supervisor engines.
FSU from EHSA is not supported.
To perform an FSU, perform this task:
Command Purpose
Step 1
Router# copy source_device : source_filename {disk0
| disk1}:
target_filename
Copies the new Cisco IOS image to the disk0: device or
the disk1: device on the active supervisor engine.
Or:
Router# copy source_device : source_filename
sup-bootflash:
target_filename
Copies the new Cisco IOS image to the bootflash:
device on the active supervisor engine.
Or:
Router# copy source_device : source_filename
{slavedisk0 | slavedisk1}:
target_filename
Copies the new Cisco IOS image to the disk0: device or
the disk1: device on the redundant supervisor engine.
Or:
Router# copy source_device : source_filename
slavesup-bootflash:
target_filename
Copies the new Cisco IOS image to the bootflash:
device on the redundant supervisor engine.
Step 2
Router# config terminal
Router(config)# config-register 0x2102
Router(config)# boot system flash
