A keying mechanism within a device bay allows a device connector of a device to make electrical connection with the device bay connector when a key slot of the device is located in one of a plurality of predetermined locations on the device. The keying mechanism prevents the device connector from making electrical connection with the device bay connector when the device does not have a key slot in any of the predetermined locations.

Keying mechanism for device bay

A reversible air flow fan system is described. A fan tray assembly is coupled with a chassis and a removable fan and bracket assembly that is oriented in a first direction. This removable fan and bracket assembly is configured to be removable from the fan tray assembly and being recoupled with the fan tray assembly in a second direction opposite the first direction. An air duct is coupled with and enables the exchange of air between the removable fan and bracket assembly and a first surface of the chassis. A sensor coupled with the fan tray assembly is configured for coupling with at least one bracket of the removable fan and bracket assembly when the removable fan and bracket assembly is oriented in the first direction.

A power distribution system includes a plurality of loads and a plurality of power sources. The power distribution system also includes an interconnect arrangement including a plurality of interconnects. The interconnects connect each load to a given number of different ones of the sources so that each load is fully powered notwithstanding failure of any one of the sources.

Power distribution system utilizing redundant AC sources or DC sources

Embodiments of the present invention present an apparatus coupled to an internal bus for monitoring environmental factors in a computer system including: an embedded controller having a processor; an environmental sensor that provides data related to environmental conditions; a reset generator; and a power source. A LAN interface may be configured to remotely access and control the embedded controller. Further, the internal bus may be selected from any of the following: a PCI bus, an ISA bus, a DIMM slot, a SIMM slot, a PCMCIA slot, or a server blade slot. Still further, the environmental sensor may be selected from any of the following: a DC electrical sensor; an AC electrical sensor; a temperature sensor; a humidity sensor; a force monitor sensor; a signal monitor sensor; an electrostatic discharge sensor; an activity sensor; an optical particulate sensor; a Hall Effect sensor; a global positioning sensor; or a whisker detection sensor.

Apparatus and system for monitoring environmental factors in a computer system

One embodiment disclosed relates to a system for power management of a group of computers. The system includes server side infrastructure (SSI) circuitry at each computer in the group and a centralized power management module (CPMM). The SSI circuitry includes local monitoring circuitry coupled to a central processing unit (CPU) of the computer. The CPMM has a management link to the SSI circuitry at each computer in the group. The local circuitry at each computer monitors power consumption at the CPU of that computer and transmits power consumption data to the CPMM. The CPMM applies a set of rules to the power consumption data to determine when and at which computers to enable and disable a CPU power throttling mode.

Rack-level power management of computer systems

One aspect of the present invention provides a server card that is removably insertable into a server chassis. An electronic power switching mechanism is disposed on the server card and is configured to cause three power states of the server card including a fully operational state, a standby state, and a fully shutdown state. In the fully operational state, a system power of the server card is enabled and a standby power of the server card is enabled. In the standby state, a system power of the server card is disabled and the standby power of the server card is enabled. In a shutdown state, the system power of the server card is disabled and the standby power of the server card is disabled.

Server card power switch

A power distribution system provides power source redundancy. The system includes a bank of loads and first and second groups of power sources. An interconnect arrangement includes a plurality of interconnects that connect each load to one or more sources of both the first and second groups of sources so as to be fully powered by sources of both the first and second groups of sources and such that if any one source or all sources of one of the groups of sources fails, all of the loads remain fully powered.

Power distribution system having redundant mixed sources and method

Embodiments of the invention provide a method and an apparatus for utilizing a microcontroller to provide an automatic order and timing power and reset sequencer. A first inter-integrated circuit (I2C) register table containing a modifiable system power-up sequence is accessed. An automatic system power-up operation is then performed in the order of the power-up sequence defined by the first I2C register table.

One embodiment disclosed relates to an apparatus for supplying redundant power to a plurality of computer systems. The apparatus includes at least one bus bar, a plurality of power supplies each supplying power at a same voltage level, a plurality of power switches, and a power supply management controller. Power inputs of the computer systems are connected to the at least one bus bar. The power supplies are selectively connected to the at least one bus bar using the power switches. The power supply management controller controls the power switches such that the power is supplied redundantly to the computer systems.
