1.
Determine whether the RE module is the master or backup using one of these methods:
• Look at the
MS
(master) LED on the RE module faceplate. If the
MS
LED is lit steady
green, the RE module is the master. If it is blinking green, the RE module is the backup.
• Issue the following CLI command:
user@switch> show chassis routing-engine
Routing Engine status:
Slot 0: Current state Master
Election priority Master (default) ...
2.
If the RE module that you want to remove is the master, make it the backup module:
user@switch>
request chassis routing-engine master switch
3.
From the master, halt the other Routing Engine:
user@switch> request system halt other-routing-engine
4.
Wait a minute or two for the Routing Engine to halt before proceeding. If you are using
a console connection, you will see a message when the system is halted. If the Routing
Engine has not yet halted, the following step returns an error.
5.
Take the backup RE module offline:
user@switch> request chassis cb offline slot slot-number
where
slot-number
is either
0
(slot SRE0) or
1
(slot SRE1).
6.
(Optional) Confirm that the RE module is offline:
user@switch> show chassis environment cb
If the state field in the command output shows that the module is offline, then it is safe
to remove the RE module.
Taking an RE Module Offline in a Switch With One RE Module
To take the RE module offline:
1.
Connect to the console port on the RE module.
2.
From the console, halt the RE module:
user@switch>
request system halt
The RE module is gracefully halted but not powered off.
When a message appears confirming that the operating system has halted, it is safe to
remove the RE module. The Routing Engine might take up to 5 minutes to gracefully halt.
