Abstract
An information handling system comprising at least one power supply unit (PSU), at least one blade server module (BSM) and at least one module monitor board (MMB). The at least one PSU, at least one BSM and the at least one MMB may be removable from the information handling system. The at least one PSU may store in a memory device, e.g., I2C device, the most recent power control command and will thereby maintain that most recent power control command when all of the at least one MMBs are removed from or operationally fail in the information handling system.
Claims32
An information handing system having a power supply with operating command memory, said system comprising:
- at least one power supply unit having operating command memory for storing a most recent operating command;
- at least one server module;
- a power distribution board;
- and
- at least one module monitor board,
- wherein the at least one power supply unit, the at least one server module and the at least one module monitor board are coupled together through the power distribution board, and
- whereby the at least one power supply unit continues to function at the most recent operating command when the at least one module monitor board fails or is decoupled from the power distribution board.
An information handing system having a power supply with operating command memory, said system comprising:
- a plurality of power supply units, each one of the plurality of power supply units having an operating command memory for storing a most recent operating command;
- a plurality of blade server modules;
- a power distribution board;
- and
- at least two module monitor boards,
- wherein the plurality of power supply units, the plurality of blade server modules and the at least two module monitor boards are coupled together through the power distribution board, and
- whereby the plurality of power supply units continue to function at the most recent operating commands stored in the operating command memories when the at least two module monitor boards both fail or are both decoupled from the power distribution board.
A power supply, comprising:
- a power circuit adapted for supplying operating power to a server module;
- on/off control logic for controlling the power circuit;
- and
- a control device having memory storage,
- wherein the on/off control logic has a first control input adapted for coupling to a first control output of a module monitor board and a second control input coupled to the control device having memory storage, whereby the control device having memory storage retains a most recent operating command from the module monitor board.
