Dell PowerEdge 4600

Power

The PowerEdge 4600 is available in either non-redundant or redundant power configurations. Three 300-watt power supplies are required as the minimum for proper system function. A fourth 300-watt power supply must be present for the system to meet the 3+1 configuration required for redundancy.
At its peak load, the PowerEdge 4600 requires no more than 783 watts of power. In the non-redundant configuration, this load is shared by three 300-watt power supplies. When a fourth power supply is present, each of the four power supplies shares the power load, each providing approximately 196 watts of power. If the system is in a redundant configuration and a power supply fails, the remaining three power supplies will pick up the load and power the system. Once the failed power supply is hot-swapped, the system will again spread the load back over the four power supplies.

With either power supply option installed, system power will be "soft-switched." This allows power cycling with the switch on the front of the system enclosure, or via software control. The power system is compatible with industry standards, such as ACPI 1.0 and Microsoft NT Server H/W Design Guide v2.0.

PSDB- Power Supply Distribution Board

The Power Supply Distribution Board is located below the system chassis and provides the following system functions:

• AC switching
• Hot plug logic
• Power distribution
• Functional control of the power supply system.

Integrated Transfer Switch

The PowerEdge 4600 is equipped with an AC transfer switch. If connected to two different AC lines, this allows the system to automatically switch to a different AC source as needed.

The AC inputs on the PowerEdge 4600 are designated as either Primary, or Secondary. If AC is good on the Primary input, then the system will utilize it for powering the system exclusively. The system will draw power from the Secondary input only if the Primary input's AC fails. This function is intended to allow administrators to designate servers to a particular AC power circuit in a multi-circuit data center environment. AC power status information is communicated to the administrator via ESM3.
