Disconnect AC Power from the Router

To disconnect AC power from the router, follow this procedure:

On the console or other management device connected to the Routing Engine, enter CLI operational mode and issue the following command to shut down the router software cleanly and preserve Routing Engine state information.
user@host> request system halt
Wait until a message appears on the console confirming that the operating system has halted.

For more information about the command, see the JUNOS Internet Software Operational Mode Command Reference: Protocols, Class of Service, Chassis, and Management.
Press the power switch on each power supply faceplate to the OFF (O) position.
Unplug the power cord from each power supply.

When multiple AC power supplies are installed in the chassis, each power cord (one for each power supply) must be unplugged to disconnect power completely.
