IMPORTANT: In installations configured with the HP BladeSystem 1U
Power Enclosures and Power Supplies, the power zones are calculated
dynamically using the topology information from all the connected
enclosures. Disregard the power zone switch and LEDs on the
HP BladeSystem 1U Power Enclosure.
For more information on configuring the power zones, refer to the HP ProLiant
BL System Best Practices Guide.
Configuring the Dynamic Power Saver
NOTE: The Dynamic Power Saver is a feature of the HP BladeSystem
p-Class 1U Power Supply Enclosure.
NOTE: The Dynamic Power Saver configures the available power
supplies to operate at maximum efficiency.
When the Dynamic Power Saver feature is enabled, the total enclosure power
consumption is monitored in real time. Power supplies are placed in a standby
condition when the power demand from the server enclosure is low. When power
demand increases, the standby power supplies instantaneously deliver the
required power. This enables the enclosure to operate at optimum efficiency.
