Emergency Power Reduction
8 Emergency Power Reduction (EPR) feature with OpenManage Enterprise Power Manager
2 Emergency Power Reduction
In case of an emergency event such as a power failure forcing the datacenter to run on a backup power
supply or a failure of the datacenter cooling mechanism, an administrator can initiate EPR to reduce the
overall power consumption of the managed devices.
Based on the priority of managed devices, use different EPR actions for different devices. Throttle and
Graceful Shutdown are the two different EPR actions supported by Power Manager.
2.1 EPR Throttle
EPR Throttle is supported for PowerEdge servers and chassis. Applying this EPR action throttles power on
the devices down to an extremely low level. Configuring devices to a minimal power consumption state
impacts the overall system performance.
2.2 EPR Shutdown
EPR Shutdown is supported only for PowerEdge servers. All the selected devices or devices part of a group
are gracefully shutdown.
2.3 Prerequisites for EPR Actions
This section provides an overview about the list of prerequisites required for performing EPR actions on
Power Manager monitored devices.
2.3.1 License Requirements
You can apply EPR Throttle on servers (iDRAC) and chassis managed by Dell EMC OpenManage Enterprise
Power Manager with OpenManage Enterprise Advanced and corresponding iDRAC Enterprise, CMC
Enterprise or iDRAC Datacenter license.
EPR Shutdown is supported only for servers with OpenManage Enterprise Advanced license and iDRAC
Express, Enterprise or Datacenter license installed.
