Abstract
An improved power supply subsystem, which is automatically updatable, includes a first power supply having a first power circuit, a first controller adapted to control operation of the first power circuit, a first interface adapted to connect the first controller to an external device, and a first bi-directional peer-to-peer port. The power supply subsystem further includes a second power supply having a second power circuit, a second controller adapted to control operation of the second power circuit, a second interface adapted to connect the second controller to the external device, and a second bi-directional peer-to-peer port. The power supply subsystem further includes a bi-directional peer-to-peer communications channel interconnecting the first bi-directional peer-to-peer port of the first power supply and the second bi-directional peer-to-peer port of the second power supply to form, between the first and second power supplies, a communications link that is separated from the first and second interfaces.
