Managing and Monitoring Power
The PowerEdge VRTX chassis is the most power-ecient modular 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.
The Power Management features of the PowerEdge VRTX help administrators congure the enclosure to reduce power consumption and
to adjust the power as required specic to the environment.
The PowerEdge VRTX modular enclosure consumes AC power and distributes the load across all active internal power supply units (PSUs).
The system can deliver up to 4800 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 VRTX enclosure can be congured for any of the two 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
• Dynamic power supply engagement (DPSE)
OMPC then manages:
• Server power
• Server priority
• System Input Power Capacity
• Maximum Power Conservation Mode
NOTE
: Actual power delivery is based on conguration and workload.
You can use the CMC web interface or RACADM to manage and congure power controls on CMC:
• View power allocations, consumption, and 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
• Dynamic Power Supply Engagement
• Default Redundancy Conguration
• Power Budgeting For Hardware Modules
• Server Slot Power Priority Settings
