Removing The Power Supply Unit Blank - Dell PowerEdge R630 Owner's Manual

If having both power supplies active is more efficient than having one power supply in a sleep state, the
active power supply can also activate a sleeping power supply.
The default power supply settings are as follows:
• If the load on the active power supply is more than 50%, then the redundant power supply is switched
to the active state.
• If the load on the active power supply falls below 20%, then the redundant power supply is switched
to the sleep state
You can configure the Hot Spare feature using the iDRAC settings. For more information on iDRAC
settings, see the Integrated Dell Remote Access Controller User's Guide at dell.com/support/manuals.

Removing the power supply unit blank

If you are installing a second power supply unit, remove the power supply unit blank in the bay by
pulling the blank outward.
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.
