Feature
Description
Active power management
(redundant PSU 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.
Dell Fresh Air cooling
(Dual PSUs are required)
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.
Rack infrastructure
Dell offers some of the industry’s highest-efficiency power infrastructure
solutions, including:
Power distribution units (PDUs)
Uninterruptible power supplies (UPS)
Energy Smart containment rack enclosures

Power supply units
Energy Smart power supplies (redundant 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 R520 supports a power supply subsystem consisting of either a single (non-redundant) power
supply or up to two AC-DC/DC-DC, hot-plug, redundant 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. A redundant system, which is managed through a PMBus
interface, consists of two power supplies with 1 + 1 redundancy, auto-sensing and auto-switching
capability.
The following power supply options are available for the R520:
495W AC, hot-plug redundant
550W AC, non-redundant
750W AC, hot-plug redundant
1100W AC, hot-plug redundant
1100W DC, hot-plug redundant
