Power supply units
The PowerEdge R340 power supply subsystem consists of one or two AC power supplies (1+1 redundant conguration only supports
a 51.3mm PSU). The power supply provides +12V and +12Vaux for non-redundant and redundant design. There are several voltage
regulators in the system to supply dierent voltage levels needed by dierent logic devices. The redundant power supplies are
managed through a PMBus interface.
The following table shows the power eciency of the power supply units:

Thermal
The thermal design of the PowerEdge R340 reects the following:
Feature
Description
Optimized thermal design
• The system layout is architected for optimum thermal
design i.e. system component placement and layout are
designed to provide maximum airow coverage to critical
components with minimum expense of fan power.
• Custom heat sink designs for CPU, chipset for optimum
component cooling.
Comprehensive thermal
management
The power required to cool a server can contribute a
signicant amount to the overall system power. Thermal
control is the active management of system cooling through
fan speed and system power management to make sure that
the system is reliable while minimizing system fan power
consumption, airow, and system acoustic output.
