Disconnecting AC Power from the Router

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

1. On the console or other management device connected to the master Routing Engine, enter CLI operational mode and issue the following command to shut down the router software. (If two Routing Engines are installed, also issue the command on the backup Routing Engine.)
   user@host> request system halt

   Note: Wait until a message appears on the console confirming that the operating system has halted.

   For more information about the command, see the JUNOS System Basics and Services Command Reference.

2. Press the power switch on each power supply faceplate to the OFF (O) position.
3. Unplug the power cord from each power supply.

   Note: 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.
