Dell PowerConnect J-Series J-EX8208 Ethernet Switch Hardware Guide 1. Determine whether the SRE module is the master or backup using one of these methods: • Look at the MS (master) LED on the SRE module faceplate. If the MS LED is lit 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) ... 2. If the SRE 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 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. Taking an SRE Module Offline in a Switch With One SRE Module To take the SRE module offline: 1. Connect to the console port on the SRE module. 2. From the console, halt the SRE 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 SRE module. The Routing Engine might take up to 5 minutes to gracefully halt.
