Abstract
Abstract The present invention provides a low cost, low complexity, redundant power supply for an electronic data system. The low complexity of the system minimizes system failure rate while the redundancy improves system availability. The redundant power supply interconnect system is comprised of: a first electronic device including a first power supply; a second electronic device including a control means, a second power supply and a third power supply, wherein the first power supply means of the first electronic device is electrically coupled to the control means of the second electronic device; a first dedicated bus electrically coupling the first electronic device to the second electronic device; and a first serial management bus, the first serial management bus electrically coupling the first electronic device to the control means of the second electronic device.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
130 words
A redundant power supply interconnect system comprising: a first electronic device including a first power supply; a second electronic device including a first control means, a second power supply and a third power supply, wherein the second power supply means and the third power supply means are connected to the first control means and provide redundant power supply to the second electronic device and the control means thereof; and a first management bus, the first management bus electrically coupling the first electronic device to the control means of the second electronic device, wherein the first power supply of the first electronic device is electrically coupled to the control means of the second electronic device via a power bus to provide an additional redundant power supply for the second electronic device.
Claim 2
Dependent Claim
130 words
A redundant power supply interconnect system comprising: a first electronic device including a first power supply; a second electronic device including a first control means, a second power supply and a third power supply, wherein the second power supply means and the third power supply means are connected to the first control means and provide redundant power supply to the second electronic device and the control means thereof; and a first management bus, the first management bus electrically coupling the first electronic device to the control means of the second electronic device, wherein the first power supply of the first electronic device is electrically coupled to the control means of the second electronic device via a power bus to provide an additional redundant power supply for the second electronic device.
Claim 3
Dependent Claim
23 words
The system recited in claim 1, further including a first dedicated bus electrically coupling the first electronic device to the second electronic device.
Claim 4
Dependent Claim
20 words
The system recited in claim 1 wherein the first electronic device and the second electronic device are storage system devices.
Claim 5
Dependent Claim
37 words
The system recited in claim 1 wherein the first electronic device is a server and wherein further the first control means of the second electronic device includes a controller, a bus transceiver and a power supply bus.
Claim 6
Dependent Claim
21 words
The system recited in claim 4 wherein the controller may be accessed remotely from the server via the first management bus.
Claim 7
Dependent Claim
26 words
The system recited in claim 4 further including a memory means for logging system information, said memory means being electrically coupled to said first control means.
Claim 8
Dependent Claim
103 words
The system recited in claim 1 further including a third electronic device, the third electronic device including a second control means, a fourth power supply and a fifth power supply, wherein the fourth power supply means and the fifth power supply means are connected to the second control means and provide redundant power supply to the third electronic device and the control means thereof; and wherein the first power supply of the first electronic device is electrically coupled to the control means of the third electronic device via a power bus to provide an additional redundant power supply for the third electronic device.
Claim 9
Dependent Claim
27 words
The system recited in claim 7 further including a second management bus, the second management bus electrically coupling the first electronic device to the third electronic device.
Claim 10
Dependent Claim
29 words
The system recited in claim 7 wherein the first control means of the second electronic device is electrically coupled to the second control means of the third electronic device.
Claim 11
Dependent Claim
42 words
The system recited in claim 7 further including a further including a first dedicated bus electrically coupling the first electronic device to the second electronic device, and a second dedicated bus electrically coupling the first electronic device to the third electronic device.
Claim 12
Dependent Claim
22 words
The system recited in claim 1 further including a UPS electrically coupled between the second power supply and a first power outlet.
Claim 13
Dependent Claim
52 words
