PowerEdge R210 II Technical Guide
5 Power, Thermal, Acoustic 5.1 Power Supplies
The base system includes a single 250W power supply. This unit provides power to the planar, the
internal hard drive bays, and one slim optical disk drive bay. Power is 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. The power supply is equipped with automatic input voltage detection.
