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.
Claims19
A system for a redundant power extender, comprising:
- a first power distribution unit comprising multiple out-ports;
- a second power distribution unit comprising multiple out-ports;
- a first automatic transfer switch comprising an in-port coupled to one of the out-ports of the first power distribution unit, an in-port coupled to one of the out-ports of the second power distribution unit, and an out-port coupled to one of a number of in-ports of a device;
- and
- a second automatic transfer switch comprising an in-port coupled to one of the out-ports of the first power distribution unit, an in-port coupled to one of the out-ports of the second power distribution unit, and an out-port coupled to one of the in-ports of the device;
- wherein at least one of the out-ports of the first power distribution unit and at least one of the out ports of the second power distribution unit are coupled, respectively, to ones of the in-ports of the device without passing through any automatic transfer switch.
A system for a redundant power extender, comprising:
- a first automatic transfer switch comprising a number of in-ports coupled to a first power feed and a second power feed and comprising an out-port coupled to a first in-port of a device;
- a second automatic transfer switch comprising a number of in-ports coupled to the first power feed and the second power feed and comprising an out-port coupled to a second in-port of the device;
- a first power distribution unit;
- and
- a second power distribution unit;
- wherein the first power distribution unit and the second power distribution unit each comprise at least two out-ports;
- and
- wherein the at least two out-ports of the first power distribution unit are coupled to a third in-port and a fourth in-port of the device, bypassing the first and second automatic transfer switches.
A method for a redundant power extender, comprising:
- receiving power and communication at a server power distribution unit from a first out-port of a first power distribution unit and a first automatic transfer switch, wherein the first automatic transfer switch is coupled to the first power distribution unit and a second power distribution unit;
- receiving power and communications at the server power distribution unit from a second out-port of the first power distribution unit;
- receiving power and communication at the server power distribution unit from a first out-port of the second power distribution unit and a second automatic transfer switch, wherein the second automatic transfer switch is coupled to the first power distribution unit and the second power distribution unit;
- receiving power and communications at the server power distribution unit from a second out-port of the second power distribution unit;
- wherein the second out-port of the first and second power distribution units are coupled to the server power distribution unit by bypassing the first automatic transfer switch and the second automatic transfer switch;
- and
- determining a power distribution topology coupled to the server power distribution unit based on the received power and communication.
