Powering Off the PTX1000

 

Before you power off a PTX1000:

  • 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 PTX1000.

  • Ensure that you have the following parts and tools available to power off the PTX1000:

    • 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

To power off a PTX1000:

  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.
    user@host> request vmhost halt
    Halt the system ? [yes,no] (no) yes

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

    Caution

    Although traffic and the operating system have stopped, the PTX1000 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 PTX1000.

  3. To prevent damage to the equipment caused by static discharge, 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. Disconnect power to the PTX1000:

    • 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 male 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.

  5. Remove the power source cable from the power supply faceplate:

    • AC power supply—Gently pull out the female 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 female end of the power plug connected to the power supply faceplate.
