5.1 Power Supplies

The base system includes a single 250W power supply. This unit provides power to the planar and the two internal hard drive bays. Power will be “soft-switched” allowing power cycling using a switch on the front of the system enclosure or through software control (server management functions). The power system is compatible with industry standards, such as ACPI and Server 2000.

Standard VRD (Voltage Regulator Down) modules that conform to VRD11.1 specification are used. This reduces the board layout complexity while offering design modularity. As processor speeds increase, a newer VRD can be used to accommodate the power increase with no need to re-spin the board. The VRD is integrated onto the planar and is not field upgradeable.

5.2 Power Supply Connectors on the Planar

There are 2 separate power supply connectors on the planar. One connector is an ATX connector (2x12) and the other one is a 2x2 connector to provide an additional two pins for +12V. The connector Pin definition (2 x 12 power connector) is not ATX standard.

The 2x12 connector provides 3.3V, 5V, 12V, and 12V standby to the system. (3.3V standby to system is generated from 12V standby).
