Description
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
might cause the enclosure to brown out.
Dynamic Power
Mode Insight Display
name
Description
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. This mode is not supported for
low voltage on the c7000 enclosure.
The default setting is Enabled. 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.
Power Limit
Do not set a Static Power Limit or Enclosure Dynamic Power Cap on an empty enclosure.

Enclosure Dynamic
Power Cap
Description
None An optional feature that enables you to cap the servers in an
enclosure as a group. As the servers run, the demand for
power varies for each server. A power cap for each server is
automatically adjusted to provide the server with enough
power to meet workload demands while still conforming to
the Enclosure Dynamic Power Cap.
The feature is enabled with three configuration parameters:
• Dynamic Power Cap—Total enclosure average power
will not exceed Dynamic Power Cap.
• Derated Circuit Capacity—Average power on a single
circuit will not exceed Derated Circuit Capacity.
• Rated Circuit Capacity—Peak power on a single circuit
