Abstract:
1. An information handling system comprising: a processor operable to process information; a power module operable to power up and power down the processor; an Input/Output (I/O) device operable to communicate information with the processor; a cable operable to transmit the information between the processor and I/O device; a first physical interface interfaced with the I/O device and the cable, the first physical interface operable to generate signals for communication of the information through the cable and to read signals through the cable; a second physical interface interfaced with the processor and the cable, the second physical interface operable to generate signals for communication of information through the cable and to read signals through the cable; and a power selector integrated with the I/O device operable to detect a power down indication; wherein the I/O device is operable to respond to the power down indication by issuing a forced power down signal with the first physical interface through the cable to the second physical interface, the second physical interface operable to receive the forced power down signal and to command a power down at the power module in response to the forced power down signal.
