Abstract
A backplane system for reconfigurable backplane power distribution includes circuit board slots, power entry modules, power distribution circuitry, and switching circuitry. The power distribution circuitry includes a first power configuration and a second power configuration and distributes the power from the power entry modules to at least one circuit board plugged into one of the circuit board slots. The switching circuitry switches between the first power configuration and the second power configuration to provide extended power capabilities.
Claims28
A backplane system comprising:
- circuit board slots;
- power entry modules configured to receive power from power sources;
- power distribution circuitry having a first power configuration and a second power configuration and configured to distribute the power from the power entry modules to at least one circuit board plugged into one of the circuit board slots;
- and
- switching circuitry configured to switch between the first power configuration and the second power configuration.
A method for distributing power in a backplane system, the method comprising:
- receiving power in power entry modules from power sources;
- distributing the power through power distribution circuitry in a first power configuration to at least one circuit board plugged into one of a plurality of circuit board slots;
- switching from the first power configuration to a second power configuration;
- and
- distributing the power through the power distribution circuitry in the second power configuration to the at least one circuit board plugged into the one of the plurality of circuit board slots.
A backplane system comprising:
- means for receiving power;
- means for distributing the power in a first power configuration and a second power configuration to at least one circuit board plugged into one of a plurality of circuit board slots;
- and
- means for switching between the first power configuration and the second power configuration.
