Juniper E-Series Installation And User Manual page 229

Upgrading Systems That Are Operating with Two SRP Modules
• If no firewall separates the E-series router from the network host,
copy the files to the E-series router (see
a Firewall Does Not
host1#copy hostname:/cdrom/x-y-z/x-y-z.rel x-y-z.rel
• If you are transferring the files from one E-series router to
another, copy the file to the system space of the second E-series
router from the user space of the first E-series router (see
Release Files from One E-Series Router to
appendix).
host1#copy boston:/outgoing/releases/x-y-z.rel x-y-z.rel
3
Save the current configuration.
host1#copy running-configuration system2.cnf
4
Specify that the E-series router should use the new software release
when it reboots.
host1(config)#boot system x-y-z.rel
5
Synchronize the NVS file system of the redundant module with that
of the primary module.
host1#synchronize
The redundant SRP module will automatically reboot, because the
software release that it is configured to run differs from the software
release it is running.
6
Wait for the redundant SRP module to boot, initialize, and reach the
standby state.
When the module is in standby state, the REDUNDANT LED is on
and the ONLINE LED is off. If you issue the show version
command, the state field for the module should be "standby".
After any type of reboot, the primary and redundant SRP module
NVS file systems will be unsynchronized again.
7
Synchronize the NVS file system of the redundant module with that
of the primary module.
host1#synchronize
8
Switch from the primary SRP module to the redundant SRP
module.
host1#srp switch
The redundant SRP module assumes the primary role. The former
primary SRP module reboots and assumes the redundant role.
