Description
Active power management
(hot- plug only)
Intel Node Manager
is an embedded technology that provides individual
server-level power reporting and power limiting functionality. Dell offers a
complete power management solution comprised of Intel Node Manager
accessed through Dell iDRAC Enterprise and OpenManage Power Center
that allows policy- based management of power and thermals at the
individual server, rack and data center level.
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.
Fresh Air cooling
(hot- plug PSU only)
With the thermal design and reliability of Dell products, you can have the
capability to operate at excursion- based temperatures beyond the industry
standard of 35°C (95°F) without impacting your availability model. This
solution takes into account servers, networking, storage, and other
infrastructure. Find additional information at

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 R420 power supply subsystem consists of one non-redundant or up to two hot-plug AC-DC
power supplies. The power supply provides +3.3V/5V/12V and +12Vaux for
non-redundant design and provides 12V and 12Vaux for redundant design. There are several voltage
regulators in the system to supply different voltage levels needed by different logic devices. The
redundant power supplies are managed through a PMBus interface.
The following power supply options are available for the R420:
•
550W AC, non-redundant
•
350W AC, hot-plug redundant
•
550W AC, hot-plug redundant
