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.
Downgrading JUNOSe Software
Downgrading JUNOSe software requires factory defaults installed on the router, and
can cause NVS and configuration script incompatibilities.
