Power supply units

Energy Smart power supplies (hot-plug PSUs only) have intelligent features, such as the ability to
dynamically optimize efficiency while maintaining availability and redundancy. Also featured are
enhanced power-consumption reduction technologies, such as high-efficiency power conversion
and advanced thermal-management techniques and embedded power-management features,
including high-accuracy power monitoring.
The R220 power supply subsystem consists of one non-redundant AC-DC 250W power supply AC-
DC power supply. Power cycling is enabled by a switch on the front of the chassis or controlled via
iDRAC7 with Lifecycle Controller.
The following power supply options are available for the R220:

250W AC, cabled, non-redundant

Description

Intel Node Manager: Dell offers a complete power management
solution comprised of Intel Node Manager accessed through Dell
iDRAC7 Enterprise and OpenManage Power Center that allows policy-
based management of power and thermals at the individual server, rack,
and data center level. Intel Node Manager is an embedded technology
that provides individual server-level power reporting and power limiting
functionality.

Hot spare reduces power consumption of redundant power supplies.

Thermal control of fan speed optimizes the thermal settings for your
environment to reduce fan consumption and lower system power
consumption.

Idle power enables Dell servers to run as efficiently when idle as when at
full workload.
With the thermal design and reliability of Dell products, certain
configurations have the capability to operate at excursion-based
temperatures beyond the industry standard of 35°C (95°F) up to 45°C (113°F)
for excursionary periods of time and up to a 26°C dew point at 90% relative
humidity without impacting your availability model. Find additional
information at Dell.com/FreshAir.
Dell offers some of the industry's highest-efficiency power infrastructure
solutions, including:

Power distribution units

Uninterruptible power supplies

