Taking the Host Subsystem Offline
To take the host subsystem offline perform the following steps:
1. On the external management device connected to the CB-RE, issue the request system halt
other-routing-engine operational mode command to offline the backup CB-RE. The command shuts
down the CB-RE cleanly by preserving the state information.
user@host> request system halt other-routing-engine
Wait until a message appears on the console confirming that the operating system has halted.
2. Take the Control board offline by using the request chassis cb slot 0/1 offline operational mode
command. The command shuts down the CB-RE completely.
user@host> request chassis cb slot 1 offline
