29 Emergency Power Reduction (EPR) feature with OpenManage Enterprise Power Manager
Can I rearrange devices in a Rack physical group with active EPR applied from Power Manager?
Description:
You can modify the rack slot(s) of selected device(s) (Manage Rack > Rearrange Rack > Update Rack
Slots) even if there is an active EPR applied on the Rack physical group.
Can I edit the attributes of a Static or Physical Group with active EPR?
Description:
You can monitor attributes of a Power Manager static or physical group even if there is an active EPR applied
at a group level.
Can I move device from a Rack physical group with active EPR to another Rack group in same or
different physical hierarchy?
Description:
There are two use cases to be considered in this scenario:
• Movement of device(s) from a physical group (Rack1) with or without EPR to another group (Rack2)
with active EPR.
- Movement of devices from a physical group (Rack1) with or without EPR, to another physical
group (Rack2) with EPR is restricted with a message as Unable to add the device to the rack
because the Emergency Power Reduction (EPR) feature is currently enabled on the rack <Group
Name of Rack 2>.
Recommendation:
Disable EPR applied on the physical group (Rack2) and retry the operation.
• Movement of device(s) from a physical group (Rack1) with EPR to another group (Rack2) without
EPR.
- Movement of device(s) is successful from a group (Rack1) with active EPR, if the target group
(Rack2) does not have any EPR in active state. While movement of device to Rack2 without
EPR, the EPR applied by virtue of Rack1 is removed automatically by Power Manager.
Corresponding audit log entries are available in Monitor > Audit Logs tab as follows.

Can I remove devices from a Rack physical group with active EPR?
Description:
You can remove devices from a Rack physical group with an active EPR. After you remove the devices, the
EPR applied by virtue of Rack1 is removed automatically by Power Manager. The listed EPR is removed from
Power Management > Emergency Power Reduction tab when all devices are removed from the physical
group with active EPR.
