NOTE:
When installing, hot-swapping, or hot-adding a new power supply, 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 (see Figure 1-5).
Removing the Power Supply Blank
If you are installing a second power supply, remove the power supply blank in
the bay by pulling outward on the blank.
CAUTION:
To ensure proper system cooling, the power supply blank must be
installed in the second power supply bay in a non-redundant configuration.
Remove the power supply blank only if you are installing a second power supply.
Installing the Power Supply Blank
NOTE:
Install the power supply blank only in the second power supply bay.
To install the power supply blank, align the blank with the power supply bay
and insert it into the chassis until it clicks into place.
