Managing and monitoring power

The PowerEdge FX2/FX2s chassis is the most power-ecient server enclosure. It is designed to include highly ecient power

supplies and fans, has an optimized layout for the air to ow more easily through the system, and contains power-optimized

components throughout the enclosure. The optimized hardware design is coupled with sophisticated power management capabilities

that are built into the Chassis Management Controller (CMC), power supplies, and iDRAC to allow you to further enhance power-

ecient server environment.

Power management in PowerEdge FX2/FX2s is relatively dierent from PowerEdge VRTX. One major change in the power

management technique is the use of a Closed Loop System Throttle (CLST) to maintain the desired chassis power cap. The purpose

of using this technique is that, it has a better control, also allows the chassis to make full use of the available PSU.

The Power Management features of PowerEdge FX2/FX2s help administrators congure the enclosure to reduce power

consumption and to adjust the power as required specic to the environment.

The PowerEdge FX2/FX2s enclosure consumes AC power and distributes the load across the active power supply unit (PSU). The

system can deliver up to 3371 Watts of AC power that is allocated to server modules and the associated enclosure infrastructure.

However, this capacity varies based on the power redundancy policy that you select.

The PowerEdge FX2/FX2s enclosure can be congured for any of the three redundancy policies that aect PSU behavior and

determine how chassis Redundancy state is reported to administrators.

You can also control Power management through OpenManage Power Center (OMPC). When OMPC controls power externally,

CMC continues to maintain:

• Redundancy policy

• Remote power logging

OMPC then manages:

• Server power

• System Input Power Capacity

NOTE: Actual power delivery is based on the conguration and workload.

You can use the CMC web interface or RACADM to manage and congure power controls on CMC:

• View the status for the chassis, servers, and PSUs.

• Congure power budget and redundancy policy for the chassis.

• Execute power control operations (turn on, turn o, system reset, power-cycle) for the chassis.

Redundancy policies

Redundancy policy is a congurable set of properties that determine how CMC manages power to the chassis. The following

redundancy policies are congurable:

• Grid Redundancy

• No Redundancy

• Redundancy Alerting Only
