SECTION 4. POWER, THERMAL, ACOUSTIC
A. Power Eciencies
One of the main features of the 11th generation of PowerEdge servers is enhanced power eciency. The
R610 achieves higher power eciency by implementing the following features:

B. Power Supplies
I. Main Power Supply

configuration. A 717W high-output power supply is also available. The power supplies connect directly
to the planar. There is a power cable to connect between the planar and the backplane. The R610 power
supplies do not have embedded cooling fans; the PSUs are cooled only by the system cooling fans. The
three status LEDs on the PSU have been replaced with a single bi-color LED starting with the PT build.
Starting with the 11th generation of PowerEdge servers (R710, R610, T610, M610, and M710), the
power supplies no longer have a FRU EEPROM. FRU data is now stored in the memory of the PSU
Microcontroller. Additionally, the PSU Firmware can now be updated by the BMC over the PMBus.
Power is “soft-switched,” allowing power cycling via a switch on the front of the system enclosure, or
via software control (through server
management functions).
If using only one power supply, the single PSU should be installed in the PS1 bay and a PSU Close Out
(metal cover) will be installed in the PS2 bay. The use of the PS1 bay for the single PSU configuration is
done for consistency only – there is nothing that prevents the use of the PS2 bay in a single PSU
configuration.
