Abstract:
1. A system comprising: a power supply configured to convert an alternating current (AC) power signal to a direct current (DC) power signal, and the power supply comprising a first power port and a second power port, the second power port different than the first power port; a first computer system coupled to the first power port, the power supply configured to provide DC operational power to the first computer system through the first power port as a pulse train with a varying duty cycle, and the first computer system the only computer system receiving operational power through the first power port; a second computer system different than the first computer system, the second computer system coupled to the second power port, the power supply configured to provide DC operational power to the second computer system through the second power port as a pulse train with a varying duty cycle, and the second computer system the only computer system receiving operational power from the second power port; a first cable coupling the first computer system to the first power port, wherein the first cable comprises a first sense signal line, and wherein the power supply is configured to adjust the duty cycle based on a signal carried by the first sense signal line; and a second cable coupling the second computer system to the second power port, wherein the second cable comprises a second sense signal line, and wherein the power supply is configured to adjust the duty cycle based on a signal carried by the second sense signal line.
