Rebooting or Powering Off a QFX10002

Rebooting a QFX10002

If you need to restart your QFX10002, use the appropriate CLI operational command for your model. For models QFX10002-36Q and QFX10002-72Q, use the request system reboot command. The request system reboot is not supported on the QFX10002-60C platform. Starting from Junos OS Release 19.1R1 and later, the request system reboot command is deprecated from the QFX10002-60C switch platform. Instead, use the request vmhost reboot command to reboot the QFX10002-60C device.

Powering Off a QFX10002

Before you power off a QFX10002:

Note:

Use the following procedure to turn off power on a QFX10002.

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

  • 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 QFX10002:

  1. Connect to the switch using one of the following methods:
  2. Shut down Junos OS from the external management device by issuing the request system halt operational mode CLI command. This command shuts down the switch 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, depending on the hardware being shut down) after entering the command:

    CAUTION:

    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 QFX10002 power module LEDs are still lit and a fan continues to run. Wait at least 60 seconds after first seeing this message before following the instructions in Step 4 and Step 5 to remove power from the switch.

  3. Attach the grounding strap to your bare wrist and to a site ESD point.
  4. Disconnect power to the switch by performing one of the following tasks:

    • 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 coupler for the power cord from the faceplate.

    • 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—Remove the power cord from the power supply faceplate by detaching the power cord retainer and gently pulling out the plug end of the power cord connected to the power supply faceplate.

    • DC power supply—Loosen and the thumbscrews securing the DC power connector on the power source cables. Remove the power source cables from the power supply.

  6. Uncable the switch before removing it from the rack or cabinet.
