System and method for providing redundant power to a device
First Claim
1. A system for providing redundant power to a device, the system comprising:
- a first power supply unit, the first power supply unit including a first power module that provides power and a first communication module including first and second first power supply unit transmitters and first and second first power supply unit receivers, wherein the first power module is selectively connectable to input lines; and
a second power supply unit, the second power supply unit including a second power module selectively connectable to the input lines and that provides power and a second communication module coupled to the first communication module and including first and second second power supply unit transmitters and first and second second power supply unit receivers coupled, respectively, to the first and second first power supply unit transmitters;
wherein the first power supply unit transmits on both the first and second first transmitters and the second power supply is configured to provide power to the device in the event that signals are not received from both the first and second first power supply unit transmitters by the first and second second power supply unit receivers.

Abstract
A system for providing redundant power to a device includes a first power supply unit that includes a first communication module including first and second first power supply unit transmitters and first and second first power supply unit receivers and a second power supply unit that includes a second communication module coupled to the first communication module and including first and second second power supply unit transmitters and first and second second power supply unit receivers coupled, respectively, to the first and second first power supply unit transmitters. The first power supply unit transmits on both the first and second first transmitters and the second power supply is configured to provide power to the device in the event that signals are not received from both the first and second first power supply unit transmitters by the first and second second power supply unit receivers.
