Powering Off the MX480 Router

Note: After powering off a power supply, wait at least 60 seconds before turning it back on.

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
2. 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 .
3. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
4. Move the AC input switch on each AC power supply or the DC circuit breaker on each DC power supply to the off (O) position.
