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 providing 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.
•
Failed Redundant
—On servers that support four power supplies, this status indicates that the
number of power supplies providing power to the server is less than the number required for
server operation. The server might continue to operate, but there is a higher risk of power issues in
this state. Verify that your power supply redundancy setting is correct in the ROM-based system
utilities.
•
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.
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.
