Power supply units

The M1000e chassis enclosure provides power and cooling for the M420 blade server. For
information on the M1000e power supply units, see the
Dell.com/PowerEdge.

Thermal and acoustics

High density and high performance of the PowerEdge M420 requires an aggressive thermal
management solution to address the high heat density in the small form factor blades. Optimized
thermal management keeps fan speeds in the PowerEdge M420 as low as possible, contributing to
quiet operation and ensuring proper component cooling.
Thermal design
The thermal design of the PowerEdge M420 reflects the following:
Comprehensive thermal management: The PowerEdge M420 dynamically controls system
cooling fan speed, based on responses from critical sensors that monitor the temperature of
several components, including:
Processors

Description
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 iDRAC7 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.
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
Energy Smart containment rack enclosures
