Taking An Sre Module Offline In A Switch With One Sre Module - Juniper EX8208 Hardware Manual

1. Determine whether the SRE module is the primary or backup using one of these methods:
Look at the MS (primary) LED on the SRE module faceplate. If the MS LED is lit steady green, the
SRE module is the primary. 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) ...
2. If the SRE module that you want to remove is the primary, make it the backup module:
user@switch> request chassis routing-engine master switch
3. From the primary, 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 SRE 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 SRE 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 SRE
module.
