Power Supplies; Removing A Power Supply - Dell PowerEdge R610 Hardware Owner's Manual

Power Supplies

Your system supports the following power supply modules:
• 717-W High Output power supply
• 502-W Energy Smart power supply (the default power supply option for
this system)
NOTE:
The system does not support a mixed installation of High Output and Energy
Smart power supplies.
If only one power supply is installed, it must be installed in the PS1 power
supply bay.

Removing a Power Supply

CAUTION:
To ensure proper system cooling, the power supply blank must be
installed in power supply bay PS2 in a non-redundant configuration. See
"Removing the Power Supply Blank."
CAUTION:
If troubleshooting a PSU mismatch error, replace only the power
supply with the flashing indicator. Swapping the opposite power supply to create
a matched pair can result in an error condition and unexpected system shutdown.
To change from a High Output configuration to an Energy Smart configuration or
vice versa, you must power down the system.
1 Disconnect the power cable from the power source and the power supply
you intend to remove and remove the cables from the Velcro strap.
2 Press the lever release latch and slide the power supply out of the chassis.
See Figure 3-7.
