Temperature-Triggered EPR (Throttle)
17 Emergency Power Reduction (EPR) feature with OpenManage Enterprise Power Manager
5 Temperature-Triggered EPR (Throttle)
Use Temperature-Triggered policy to prevent damage to devices due to overheating in the event of cooling
infrastructure failure. It limits the processing capability of the devices in the group, hence reducing the
possibility of any damage to device due to overheating. The policy helps in maintaining data center
temperature to align to the standards defined by American Society of Heating, Refrigerating and Air-
Conditioning Engineers (ASHRAE).
Create Temperature-Triggered policy on a group (static or physical) monitored by Power Manager, by
defining a temperature threshold value. After defining the threshold value and enabling the policy, if the
average inlet temperature of the group crosses the temperature threshold value, Power Manager enforces an
EPR (Throttle) on the group. On the EPR tab (Power Management > Emergency Power Reduction), the
source of EPR (Throttle) is displayed as Temperature-Triggered.
