Upgrading Systems That Are Operating With Two Srp Modules - Juniper E Series Hardware Manual

Upgrading Systems That Are Operating with Two SRP Modules

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:
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.
2. Copy the new release of the software to NVS of the primary SRP module. Be
3. Save the current configuration. For example:
Be sure to specify the correct software release (.rel) filename for the router you
are using, as described in
host1#copy boston:/outgoing/releases/erx_x-y-z.rel erx_x-y-z.rel
You must upgrade the software on the redundant SRP module when you
host1(config)#disable-autosync
sure to specify the correct software release (.rel) filename for the router you are
using, as described in Identifying the Software Release
! 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
For example:
host1#copy /incoming/releases/erx_x-y-z.rel erx_x-y-z.rel
! If no firewall separates the E-series router from the network host, copy the
files to the E-series router (see
Exist). 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 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
to Another). For example:
host1#copy boston:/outgoing/releases/erx_x-y-z.rel erx_x-y-z.rel
host1#copy running-configuration system2.cnf
