Managing and Monitoring Power
The PowerEdge FX2/FX2s chassis is the most power-efficient server enclosure. It is designed to include
highly efficient power supplies and fans, has an optimized layout for the air to flow 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-efficient server environment.
Power management in PowerEdge FX2/FX2s is relatively different 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 configure the enclosure to
reduce power consumption and to adjust the power as required specific 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 configured for any of the three redundancy policies that
affect 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 configuration and workload.
You can use the CMC web interface or RACADM to manage and configure power controls on CMC:
• View the status for the chassis, servers, and PSUs.
• Configure power budget and redundancy policy for the chassis.
• Execute power control operations (turn on, turn off, system reset, power-cycle) for the chassis.
