Powering Off the T640 Router

 

To power off a T640 router:

  1. On the external management device connected to the Routing Engine, issue the request system halt operational mode command. The command shuts down both 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

    For more information about these commands, see request system halt.

  2. Wait until a message appears on the console confirming that the operating system has halted.
  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. Switch the circuit breakers on each two-input 160-A DC power supply, three-input 240-A DC power supply, or four-input 240-A DC power supply faceplate to the off position (O) or switch the power switch on each AC power supply or six-input DC power supply faceplate to the standby position.
