196 Installing System Components

Power Sled

NOTE: This section applies to PowerEdge C8000 server enclosure with internal

power source.

Enclosure Power Guidelines

Observe the following guidelines when connecting power to the enclosure:

• Always connect the enclosure’s AC power sockets to a single power source,

switch, or PDU.

• Make sure to install the power sleds and connect power to the enclosure

before you install any other sled.

Power Sled Installation Guidelines

Follow these guidelines when installing power sleds.

• If a power supply is removed from the enclosure and the power supply

number in the enclosure is less than the required number of power

supplies, all sleds in the enclosure will be throttled until the failed PSU

module is replaced. For example, in a 2+2 PSU configuration, if three PSU

modules fail, it would trigger the sleds in the enclosure to throttle. When

the failed PSU modules are replaced the enclosure exits power throttling

mode and resume operating normally.

NOTE: Throttling reduces power consumption of the sled modules by changing the

processor duty cycle, thereby reducing sled performance. When a throttling event

occurs the event is logged in the System Event Log (SEL). See the Using the

Baseboard Management Controller Guide at dell.com/support/manuals for more

information.

• The following table lists the supported configuration where power supply

redundancy is guaranteed.

NOTE: Configurations higher than indicated in the table may change the power

supply mode to non-redundant. In non-redundant mode, if the power requirement

exceeds the installed system power capacity, BIOS will throttle the processors. If

CPU power capping is enabled, throttling can occur on processors that exceed the

cap value. See "Power Management" on page 78 for more information.
