Powering Off the PTX10002-60C

  • Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage. See Prevention of Electrostatic Discharge Damage.

  • Ensure that you do not need to route traffic through the PTX10002-60C.

  • Ensure that you have the following parts and tools available to power off the PTX10002-60C:

    • An ESD grounding strap

    • An external management device such as a PC

    • An RJ-45 to DB-9 rollover cable to connect the external management device to the console port

Use the following procedure to power off a PTX10002-60C.

To power off a PTX10002-60C:

  1. Connect to the router by using one of the following methods:
  2. Shut down Junos OS from the external management device by issuing the request vmhost halt operational mode CLI command. This command shuts down Junos OS gracefully and preserves system state information. A message appears on the console, confirming that the operating system has halted.

    You see the following output (or something similar) after entering the command:


    The final output of any version of the request system halt command is the “The operating system has halted.” Although traffic and the operating system have stopped, the PTX10002-60C PSM LEDs remain lit and a fan module continues to run. Wait at least 60 seconds after first seeing this message before following the instructions in Step 4 and Step 5 to power off the PTX10002-60C.

  3. Disconnect power to the PTX10002-60C:
    • AC power supply—If the AC power source outlet has a power switch, set it to the off (O) position. If the AC power source outlet does not have a power switch, gently pull out the plug end of the power cord connected to the power source outlet.

    • DC power supply—Switch the circuit breaker on the panel board that services the DC circuit to the off position.

  4. Remove the power source cable from the power supply faceplate:
    • AC power supply—Gently pull out the socket end of the power plug connected to the power supply faceplate.

    • DC power supply—Loosen the thumb screws for the power cable. Gently pull out the socket end of the power plug connected to the power supply faceplate.

  5. Uncable the switch before removing it from the rack.
