This example shows how to perform a software upgrade:
Switch# config terminal
Switch(config)# config-register 0x2
Switch(config)# boot system flash
bootflash0:cat4500e-universalk9.SSA.03.01.00.150.1.XO.bin
Switch(config)# redundancy
Switch(config-red)# main-cpu
Switch(config-r-mc)# auto-syn standard
Switch(config-r-mc)# end
Switch# copy running-config start-config
Switch# redundancy reload peer
Switch# redundancy force-switchover

Purpose
Copies the new Cisco IOS-XE software image to
bootflash on the supervisor engine.
Copies the new image to a device on the standby
supervisor engine (such as slavebootflash and slaveslot0).
Configures the supervisor engines to boot the new image.
If your system was configured to autoboot an earlier
image, issue the following command string to boot the
new image instead:
no boot system flash device:old_file_name
Enters redundancy configuration mode.
Enters main-cpu configuration submode.
Synchronizes the configuration elements.
Returns to privileged EXEC mode.
Saves the configuration.
Reloads the standby supervisor engine and brings it back
online (using the new release of the Cisco IOS-XE
software).
Conducts a manual switchover to the standby supervisor
engine. The standby supervisor engine becomes the new
active supervisor engine using the new Cisco IOS-XE
software image.
The old active supervisor engine reboots with the new
image and becomes the standby supervisor engine.
