Powering Off the M120 Router

To power off the router:

1. On the external management device connected to the Routing Engine, issue the request system halt both-routing-engines operational mode command. The command shuts down the Routing Engines cleanly, so their state information is preserved. (If the router contains only one Routing Engine, issue the request system halt command.)
   
   

   user@host> request system halt both-routing-engines

   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. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
3. Switch the circuit breaker on each DC power supply faceplate to the off position (O). For the AC power supply, move the power switch to the standby position.
