Viewing a rack utilization graph
Dell OpenManage Power Center allows you to view a graphical representation of different aspects of rack
utilization for custom and physical entitles within the Power Center system. This information can help
you determine the availability of space and power within specific racks to add new devices.
1. In the left pane, click Devices → Managed Group.
2. From the list of device groups, select a group that contains a rack device.
The details of the device are displayed in the Details section.
3. Click Power & Thermal → View Rack Utilization.
Alternately, you can also click Summary → View Rack Utilization.
The Utilization window is displayed.
NOTE: The Rack Utilization option is available only for groups of the types — datacenter, room,
and aisle.
4. Click the Power Utilization or Space Utilization, and Actual or Percentage options to change the
data viewed.
5. Click X in the upper-right corner to return to the Managed Groups tab.
A rack may not be displayed in the rack utilization graph if:
• the actual power of a device or devices in the rack exceeds the specified power capacity.
• the estimated maximum power for a device in the rack is not set.

Emergency Power Reduction
When there is an emergency situation—for example, a power failure and your devices are running on
UPS, you can initiate Emergency Power Reduction to reduce the power consumption of your managed
devices.
CAUTION:
Applying emergency power reduction will throttle power on the devices down to an extremely low
level, which will impact performance. All devices with Monitor & Capping power capability are
impacted. Use this only in an emergency situation.
All of the devices with the Monitor & Capping power capability within this group are set to the minimal
power consumption state. The Emergency Power Reduction button appears in the upper-right corner of
all pages. The devices impacted by emergency power reduction are marked with EPR in the Devices
screen.
