ABSTRACT:
Through a menu driven selection procedure, a user is given options for how a server should respond to an actuation of a power switch. In one option, the power switch is disabled to prevent accidental shut down of the power supply in response to power switch actuation. In another option, the shut down of the power supply follows soon after the expiration of a count down timer which is triggered by power switch actuation. A subsequent actuation of the power switch in this option aborts the count down. In yet another option, the shut down of the power supply follows soon after the completion of a graceful shut down of the server operating system which is triggered by power switch actuation. A subsequent actuation of the power switch in this option causes an immediate shut down of the power supply.
