    Powering Off the DC-Powered MX2020 Router

    Note: After powering off a 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 their state information is preserved. If the router contains only one CB-RE, 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 PDF Document.
    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 DC power switch on the DC PSM faceplate for each DC PSM to the off (O) position, and move the DC circuit breaker from the power source input for each DC PDM to the (OFF) position.
