5 Power, Thermal, Acoustic
5.1 Power Supplies
The Dell™ PowerEdge™ R410 is powered by a non-redundant 480W power supply and redundant 500W
power supply. The power supply has automatic input voltage detection. An auxiliary power-out
receptacle is not provided.
The power supply in the chassis has been rated as 82%, efficient at 20%, and 100% load, and 85%
efficient at 50% load under 115V AC input line. Redundant power efficiency is 88% at 20% load, 100%
load, 92% efficiency at 50% load under 230V AC input line.
The base system includes a single 480W power supply. This unit provides power to the PowerEdge
R410 planar, the four internal hard drive bays, and one slim optical disk drive bay. Power is soft-
switched allowing power cycling via a switch on the front of the system enclosure or via software
control (through server management functions). The power system is compatible with industry
standards, such as ACPI and Server 2000.
There are two separate power supply connectors on the planar: an ATX connector (2x12) and a 2x4
connector to provide an additional two pins for +12V. (The ATX connector pin definition is not
standard, and it defined by power rating calculation).
The 2x12 ATX connector provides 3.3V, 5V, 12V, and 12V standby to the system. The 5V standby is
provided to the system via a charge pump from 3.3V standby.
5.2 Power Supply Indicators
The PowerEdge R410 redundant power supplies have one status bi-color LED: green for AC power
present and amber for a fault as detailed in Table 3.
