Claim:
A power rail status indication system, comprising: a chassis including a chassis access member that allows access to a chassis housing; an auxiliary power rail that is located in the chassis and that couples to a power supply; an indicator that is located in the chassis and that is coupled to the auxiliary power rail; a switch that is located on the chassis and that provides a signal indicating a status of the chassis access member; and a signal conditioning circuit coupled to the indicator and the switch, wherein the signal conditioning circuit: allows power from the auxiliary power rail to activate the indicator to indicate that the auxiliary power rail is receiving power from the power supply in response to determining that the signal from the switch indicates that the status of the chassis access member is allowing access to the chassis housing; and prevents power from the auxiliary power rail from activating the indicator such that the indicator does not indicate that the auxiliary power rail is receiving power from the power supply in response to determining that the signal from the switch indicates that the status of the chassis access member is not allowing access to the chassis housing.
