Viewing power details

In the left pane, click Devices → All Devices or Devices → Managed Groups. Click the icon for a device

or group, then refer to the lower detail portion of the screen. While Dell OpenManage Power Center does

provide power information for PDU and other devices and groups, Power Center does not provide power

details for UPS devices.

For devices and groups (excluding PDU and UPS), by default, the Power graph displays the power details

for the previous hour. Refer to Viewing Power History Graph for details on accessing a device or group

graph.

NOTE: CMC infrastructure power adjustments are not considered when OMPC reports the Dell

modular server power reading. It is recommended to view the total power from a chassis level.

Power details for the current time window

You can view power details for the current time window by clicking a time window tab. The following

table describes the time windows and their associated intervals:

Changing the sample interval results in interval changes for the 15Min and 1H time windows. If you

change the sampling interval to 6 minutes, the interval of the 15Min time window is 3 minutes and
