5.1 Power Supplies

The 4-HDD configuration includes a 480W power supply. The 8- and 12-HDD configurations have a hot-plug redundant 1100W power supply. A hot-plug redundant 750W option is available for the 8- and 12-HDD configurations. Power is soft-switched, allowing power cycling using a switch on the front of the system enclosure or using software control (through server management functions). The power system is compatible with industry standards, such as ACPI and Server 2000.

For the 8 and 12 HDD configuration 750W hot plug redundant PSUs, Dell offers two options:

∙n+0, hot-plug non-redundant

∙n+1, hot-plug redundant

In order to supply power to the processors, standard Voltage Regulator Down (VRD) modules conform to VRD (Performance 2005 FMB) specification. This approach 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. The VRD follows Intel’s VRD11 specification.

There are 2 separate power supply connectors on the planar—one connector is an ATX connector (2x12) and the other one is a 2x4 connector to provide an additional two pins for +12V. (The ATX connector Pin definition is not standard; it is defined by power rating calculation.)

The 2x12 ATX connector provides 3.3V, 5V, 12V, and 12V standby to the system. 3.3V standby is provided to the system through a buck converter from 12V standby.
