For an EX8200 switch with redundant Routing Engines, you can minimize disrupting
network operation during a Junos OS upgrade by upgrading the Routing Engines
separately, starting with the backup Routing Engine.
To upgrade the software package on an EX8200 switch with one installed Routing Engine,
see "Installing Software on an EX Series Switch with a Single Routing Engine (CLI
Procedure)" on page 78.
Install the new Junos OS Release on the backup Routing Engine while keeping the currently
running software version on the master Routing Engine. After making sure that the new
software version is running correctly on the backup Routing Engine, switch device control
to the backup Routing Engine. Finally, install the new software on the new backup Routing
Engine.
To upgrade the Junos OS on the switch, perform the following tasks:
