  2. Turn the power switch on the rear of the workstation to the On (|) position.

  3. Press and release the power switch on the front panel.

  4. After several seconds, verify that the Platform Power LED next to the power switch is lit.

    The Platform Power LED lights after the workstation begins the internal booting process.

ProcedureTo Power Off the Workstation

  1. Save your data and close any open applications.

  2. Read the following power-off options and use one of the options to turn off the workstation.

    In most cases, this initiates an orderly shutdown of the operating system and shuts off the workstation power.

    • Power off the workstation by using the operating system shutdown command or menu option.

    • If the first option does not shut off the workstation power, press and hold the power button for approximately four seconds.

      This option shuts down the power to the workstation but does not initiate an orderly shutdown of the operating system. This option might result in data loss.

    • If the preceding options do not power off the workstation, turn the power switch on the back panel to the off (0) position.

    Potential data loss if the power is turned off using the back-panel power switch. Ensure that you have saved your data and closed any open applications before powering off the system using the back-panel power switch.

    After powering off the workstation, wait at least 10 seconds before powering on the workstation again.
