POWER SUPPLY DETECTION AND INDICATION

1. A power detection and indication circuit device comprising:

a processor;

a signal conditioning circuit coupled to the processor; and

an indicator coupled to the processor through the conditioning circuit, wherein the power detection and indication circuit performs a test to determine the presence of a switch coupled to the processor through the conditioning circuit, determining that the switch is coupled to the processor through the conditioning circuit, the power detection and indication circuit performs a test to determine a status of the switch and provides an indication of the status of the switch using the indicator.

2. The device of claim 1, wherein the status of the switch indicates an opening status of a chassis in which the device is located.

3. The device of claim 2, wherein the indicator is on when the chassis is open.

4. The device of claim 2, wherein the indicator is off when the chassis is closed.

5. The device of claim 1, wherein the indicator is a light emitting diode (LED).

6. The device of claim 1, including determining that the switch is not coupled to the processor through the conditioning circuit, the conditioning circuit turns on the indicator.

7. The device of claim 1, wherein the signal conditioning circuit and the indicator are at least partially electrically powered using an auxiliary power source.

8. An information handling system (IHS) comprising:

a processor,

a memory coupled to the processor; and

a power detection and indication circuit device including:

a signal conditioning circuit coupled to the processor; and

an indicator coupled to the processor through the conditioning circuit, wherein the power detection and indication circuit performs a test to determine the presence of a switch coupled to the processor through the conditioning circuit, determining that the switch is coupled to the processor through the conditioning circuit, the power detection and indication circuit performs a test to determine a status of the switch and provides an indication of the status of the switch using the indicator.

9. The IHS of claim 8, wherein the status of the switch indicates an opening status of a chassis in which the device is located.

10. The IHS of claim 9, wherein the indicator is on when the chassis is open.

11. The IHS of claim 9, wherein the indicator is off when the chassis is closed.

12. The IHS of claim 8, wherein the indicator is a light emitting diode (LED).

13. The IHS of claim 8, including determining that the switch is not coupled to the processor through the conditioning circuit, the conditioning circuit turns on the indicator.

14. The IHS of claim 8, wherein the signal conditioning circuit and the indicator are at least partially electrically powered using an auxiliary power source.

15. A method comprising:

initiating a test to determine the presence of a switch coupled to the processor;

in response to determining that the switch is not coupled to the processor, turning on an indicator; and

in response to determining that the switch is coupled to the processor;

initiating a test to determine a status of the switch; and

providing an indication of the status of the switch using the indicator.

16. The method of claim 15, wherein the status of the switch is indicating an opening status of a chassis in which the processor is located.

17. The method of claim 16, including turning on the indicator when the chassis is open.

18. The method of claim 16, including turning off the indicator when the chassis is closed.

19. The method of claim 15, using a light emitting diode (LED) as the indicator.

20. The method of claim 19, including powering the LED using an auxiliary power source within an information handling system (IHS).
