Powering Off the M120 Router

To power off the router:

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 OS System Basics

and Services Command Reference

Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
the strap to one of the ESD points on the chassis.

Switch the circuit breaker on each DC power supply faceplate to the off position (

For the AC power supply, move the power switch to the standby position.
