Installation Manual

Possible Power Status values follow:
• Redundant—Indicates that the power supplies are in a redundant state. If Power Discovery
Services is integrated into the infrastructure, this value indicates whether the externally
supplied power to the internal power supplies is redundant.
• Not Redundant—Indicates that at least one of the power supplies or iPDUs (if Power
Discovery Services is used) is not supplying power to the server. The most common reason
for this status is a loss of input power to the power supply. Another reason for this status is
a configuration with multiple power supplies connected to the same iPDU. In this case, the
individual power supply status is Good, In Use, but the Power Status value is Not
Redundant because the loss of input power to the iPDU would lead to a total loss of power
to the server.
• OK—A Common Slot Power Supply is not installed. The installed power supply is working
correctly.
• N/A—Only one power supply is installed. Redundancy is not applicable in this configuration.
HPE Power Discovery Services Status
The possible values follow:
• Redundant—The server is configured for a redundant iPDU configuration.
• Not Redundant—There are not sufficient iPDUs to support redundancy, or the server power
supplies are connected to the same iPDU.
• N/A—No iPDUs were discovered.
When the iLO processor or the server is reset, the iPDU discovery process might take a few
minutes to complete.
High Efficiency Mode
The redundant power supply mode that will be used when redundant power supplies are
configured.
The possible values follow:
• N/A—Not applicable.
• Balanced Mode—Delivers power equally across all installed power supplies.
• High Efficiency Mode (Auto)—Delivers full power to one of the power supplies, and places
the other power supplies on standby at a lower power-usage level. A semirandom distribution
is achieved because the Auto option chooses between the odd or even power supply based
on the server serial number.
• High Efficiency Mode (Even Supply Standby)—Delivers full power to the odd-numbered
power supplies, and places the even-numbered power supplies on standby at a lower
power-usage level.
• High Efficiency Mode (Odd Supply Standby)—Delivers full power to the even-numbered
power supplies, and places the odd-numbered power supplies on standby at a lower
power-usage level.
• Not Supported—The installed power supplies do not support High Efficiency Mode.
