methods:
Look at the (master) LED on the SRE module faceplate. If the

steady green, the SRE module is the master. If it is blinking green, the SRE 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) ...
If the SRE module that you want to remove is the master, make it the backup module:
2.
user@switch> request chassis routing-engine master switch
From the master, halt the other Routing Engine:
3.
user@switch> request system halt other-routing-engine

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.
Take the SRE module offline:
5.
user@switch> request chassis cb offline slot slot-number
where is either
slot-number
(Optional) Confirm that the SRE module is offline:
6.
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 SRE module.
To take the SRE module offline:
Connect to the console port on the SRE module.
1.
From the console, halt the SRE module:
2.
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 SRE module. The Routing Engine might take up to 5 minutes to gracefully
halt.
