HP Onboard Administrator - Manual (Page 79)

First Time Setup Wizard 79
IMPORTANT: To change the power redundancy mode, you must disable EDPC. After changing
the power redundancy mode, reset EDPC based on the new ranges.
The HP BladeSystem c3000 or c7000 Enclosure power management system enables you to configure the
enclosure to meet your needs. You can choose from the different modes on the Onboard Administrator Power
Management screen. The power modes are explained in the following table.
Mode Insight Display
name Description
Redundant Redundant For DC power supplies only. In this configuration, N power
supplies are used to provide power and N are used to
provide redundancy (where N can equal 1, 2, or 3). Up to
three power supplies can fail without causing the enclosure
to fail. When correctly wired with redundant DC line feeds,
this configuration also ensures that a DC line feed failure
does not cause the enclosure to power off.
AC Redundant AC Redundant For AC power supplies only. In this configuration, N power
supplies are used to provide power, and N are used to
provide redundancy (where N can equal 1, 2, or 3). Up to
three power supplies can fail without causing the enclosure
to fail. When correctly wired with redundant AC line feeds,
this configuration also ensures that an AC line feed failure
does not cause the enclosure to power off.
Power Supply Redundant Power Supply
Up to six power supplies can be installed with one power
supply always reserved to provide redundancy. In the event
of a single power supply failure, the redundant power supply
takes over the load. A line feed failure of more than one
power supply causes the system to power off.
Not Redundant None There is no power redundancy and no power redundancy
warnings are given. If all power supplies are needed to
supply Present Power, then any power supply or line failure
may cause the enclosure to brown-out.
Dynamic Power Dynamic Power If enabled, Dynamic Power automatically places unused
power supplies in standby mode to increase enclosure
power supply efficiency, thereby minimizing enclosure
power consumption during lower power demand. Increased
power demands automatically return standby power
supplies to full performance. More information about
Dynamic Power follows this table.
Static Power Limit Power Limit An optional setting to limit power. Whenever you attempt to
power on a device, the total power demands of the new
device and of the devices already on are compared against
this Static Power Limit. If the total power demands exceed the
limit, the new device is prevented from powering on.
See the Enclosure Dynamic Power Cap description for more
information on the Static Power Limit and how it compares to
the Enclosure Dynamic Power Cap.
Dynamic Power—The default setting is Disabled. The following selections are valid:
• Enabled—Some power supplies can be automatically placed on standby to increase overall enclosure
power subsystem efficiency.
• Disabled—All power supplies share the load. The power subsystem efficiency varies based on load.
