Upgrading Systems That Are Operating with Two SRP Modules

The procedures for transferring release files from a source E-series router
to a destination E-series router are almost identical to transferring release
files from a network host to an E-series router on the same side of the
firewall.
Note: You must enable the FTP server on the source E-series router.
To transfer release files from a source E-series router to a destination
E-series router, follow the instructions in
Firewall Does Not Exist,
• Substitute the source E-series router for the network host.
• Omit the step about mounting the CD.
• Copy the file to the system space of the second E-series router from the
user space of the first E-series router.
host1#copy boston:/outgoing/releases/x-y-z.rel x-y-z.rel
Use this procedure if the system contains two SRP modules and is already
operating with an earlier software release. Each SRP module will keep
the system operational while you upgrade the software on the other, so
that you can avoid interrupting service.
Caution: You must upgrade the software on the redundant SRP module when you
upgrade the software on the primary SRP module. This action prevents the
redundant SRP module from overwriting the new software on the primary SRP
module if the primary SRP module fails and the redundant SRP module assumes
control.
To upgrade the software on a system that is operational and contains two
SRP modules:
1
Turn off autosynchronization.
host1(config)#disable-autosync
2
Copy the new release of the software to NVS of the primary SRP
module.
• If a firewall separates the E-series router from the network host,
transfer files to the user space with the FTP client on the network
host, and install files on the system space (see
When a Firewall
