If no firewall separates the router from the network host, copy the files to the router
(See "Installing Software When a Firewall Does Not Exist" on page 124 .) For example:
host1#copy hostname:/cdrom/x-y-z/erx_x-y-z.rel erx_x-y-z.rel
If you are transferring the files from one router to another, copy the file to the system
space of the second router from the user space of the first router (See "Copying
Release Files from One Router to Another" on page 130.) For example:
host1#copy boston:/outgoing/releases/erx_x-y-z.rel erx_x-y-z.rel
Save the current configuration. For example:

host1#copy running-configuration system2.cnf
Specify that the router should use the new software release when it reboots. For

example:
host1(config)#boot system erx_x-y-z.rel

module.
host1#synchronize
The redundant SRP module automatically reboots because the software release that
it is configured to run differs from the software release it is running.
CAUTION: The secondary SRP module does not run the new software
until it reboots. If you issue the srp switch command or the primary SRP
module fails before the redundant SRP module reboots, then the
secondary SRP module runs with the old release when it takes control.
Wait for the redundant SRP module to boot, initialize, and reach the standby state.
6.
When the module is in standby state, the REDUNDANT LED is on and the ONLINE LED
is off. The State field in the show version display indicates the module is in standby.
After any type of reboot, the primary and redundant SRP module NVS file systems
are unsynchronized again.
Synchronize the NVS file system of the redundant module with that of the primary

module.
host1#synchronize
Switch from the primary SRP module to the redundant SRP module.
8.
host1#srp switch
The redundant SRP module becomes the primary. The former primary SRP module
reboots and becomes the redundant.
Reenable autosynchronization.
9.
host1(config)#no disable-autosync
