Redundant Power Supply Mode
NOTE: This feature is not available on SL and BL server models.
This feature enables the user to configure how the system manages power delivery to power supplies
in redundant power supply configurations.
Options include:
•
Balanced Mode (default)—Shares the power delivery between all installed power supplies.
NOTE: Power delivery may not be equal between all 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 semi-random distribution is
achieved, because the Auto option chooses between the odd or even power supply based
on the server's serial number.
•
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.
•
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.
