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.
Topics:
• Redundancy policies
• Default Redundancy conguration
• Multi-node sled adaptation
• Chassis power limit monitoring
• Viewing power consumption status
• Viewing power budget status using CMC web interface
• Viewing power budget status using RACADM
