Before removing a Routing Engine (RE) module from an EX8216 switch, take the module
offline.
The RE module performs switching and system management functions in an EX8216
switch. Your switch can have either one or two RE modules.
This topic describes:

To take an RE module offline:
Determine whether the RE module is the master or backup using one of these methods:
1.
Look at the (master) LED on the RE module faceplate. If the
MS
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) ...
If the RE 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
LED is lit steady
