    Note -

    The system may take anywhere from 30 seconds to two minutes before video is displayed on the system monitor or the ok prompt appears on an attached terminal. This time depends on the level of power-on self-test (POST) diagnostics being performed.


  5. Turn the keyswitch to the Locked position.


    Note -

    The Locked position prevents accidentally powering-off the system. See "2.9.1 Keyswitch Settings" for information about each keyswitch setting.
