Removing a Routing Engine

To remove a Routing Engine, follow this procedure (see

Removing a Routing Engine
Installing a Routing Engine
Place an electrostatic bag or antistatic mat on a flat, stable surface.
If two Routing Engines are installed, use one of the following two methods to
determine which is functioning as master:
Note which of the blue
Issue the following CLI command. The master Routing Engine is designated
in the
Master Current state
user@host> show chassis routing-engine
Routing Engine status:
Slot 0:
Current state
...
If you are removing the master Routing Engine and a second Routing Engine is
installed, issue the following CLI command to switch mastership to the standby
host module:
user@host> request chassis routing-engine master switch
If the Routing Engines are configured for graceful switchover and are running a
JUNOS release that supports graceful switchover, the standby Routing Engine
immediately assumes Routing Engine functions and there is no interruption to
packet forwarding. Otherwise, packet forwarding halts while the standby Routing
Engine becomes the master and the Packet Forwarding Engine components
reset and connect to the new master Routing Engine. For information about
configuring graceful switchover, see the section about Routing Engine redundancy
in the JUNOS System Basics Configuration Guide.
