2. Shut down Junos OS from the external management device by issuing the request system halt
operational mode CLI command. This command shuts down the switch gracefully and preserves
system state information. A message appears on the console, confirming that the operating system
has halted.
You see the following output (or something similar, depending on the hardware being shut down)
after entering the command:
Shutdown NOW!
