Abstract: In one implementation, a system for a redundant power extender includes a first automatic transfer switch comprising a number of in-ports coupled to a first power distribution unit and a second power distribution unit, wherein the first automatic transfer switch comprises an out-port coupled to a first side of a device and a second automatic transfer switch comprising a number of in-ports coupled to the first distribution unit and the second power distribution unit, wherein the second automatic transfer switch comprises an out-port coupled to a second side of the device with intelligence to allow 4+4 power redundancy from a system otherwise limited to 3+3 power redundancy.
