Powering Off the AC-Powered or Universal HVAC/HVDC-Powered MX2000 Router


After powering off a power supply module (PSM), wait at least 60 seconds before turning it back on.

To power off the router:

  1. On the external management device connected to the CB-RE, issue the request system halt both-routing-engines operational mode command. The command shuts down the Routing Engine cleanly, so the state information is preserved. If the router contains only one CB-RE, issue the request system halt command.
  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 power switch on the AC or HVAC/HVDC PSM faceplate for each AC or HVAC/HVDC PSM to the off (O) position.
