Dell PowerEdge R910 - Manual (Page 156)

156 Installing System Components
CAUTION: When connecting the power cable, secure the cable with the Velcro
strap.
NOTE: When installing, hot-swapping, or hot-adding a new power supply in a
system, allow several seconds for the system to recognize the power supply and
determine its status. The power-supply status indicator turns green to signify that
the power supply is functioning properly.
Removing the Power Supply Blank
If you are installing a power supply, remove the power supply blank by pulling
outward on the blank.
CAUTION: To ensure proper system cooling, the power supply blank must be
installed in each power supply bay that does not have a power supply. Remove the
power supply blank only if you are installing an additional power supply.
Installing the Power Supply Blank
NOTE: Install the power supply blank only in power supply bays 2, 3, or 4.
To install the power supply blank, align the blank with the power supply bay
and insert the blank into the chassis until it clicks into place.
