Powering Off the AC-Powered MX2008 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 RCB, issue the request vmhost power-off operational mode command individually on both the RCBs. The command shuts down the RCB cleanly, so the state information is preserved.
    user@host> request vmhost power-off
  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. Flip the AC power switch on the AC PSM faceplate for each AC PSM to the off (O) position.
