Upgrading a System That Contains Two SRP Modules

In a system that contains two SRP modules, you can upgrade the software without powering off the system.

To upgrade the software in a system that contains two SRP modules:

1. Connect your antistatic wrist strap to the ESD grounding jack on your router.
2. Turn off autosynchronization.

   host1#enable

   host1#configure

   Configuring from terminal or file [terminal]?

   Enter configuration commands, one per line. End with CNTL/Z.

   host1 (config)#disable-autosync

   host1 (config)#exit
   

3. Halt the redundant SRP module.

   host1#halt standby-srp

   
   Remove the redundant SRP module from the chassis.

4. Replace the NVS card on this SRP module.

   Note: The release you are installing must be Release 5.1.2 or higher-numbered 5.x.x release.

5. Reinsert the SRP module into the chassis.
6. Force the redundant SRP module to take over from the primary SRP module.

   host1#srp switch
   

7. Turn on autosychronization.

   host1#enable

   host1#configure

   Configuring from terminal or file [terminal]?

   Enter configuration commands, one per line. End with CNTL/Z.

   host1 (config)#no disable-autosync

   host1 (config)#exit
   

   The software is updated on the other SRP module.

After the system is configured with a 5.x.x release, newer releases are supported and can be installed.
