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.
Topics:
• Redundancy policies
• Default Redundancy configuration
• 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
• Redundancy status and overall power health
Redundancy policies
Redundancy policy is a configurable set of properties that determine how CMC manages power to the chassis. The following redundancy
policies are configurable:
• Grid Redundancy
• No Redundancy
• Redundancy Alerting Only
