4. Click Update to update the device location with the iDRAC/CMC location.
NOTE: The location can be updated only for chassis, rack, and tower (only Dell servers).
NOTE: If the iDRAC/CMC path and the device path are not synchronized, a warning message is
displayed in Details → Device Details section. You may have to update the device path to
ensure that it is synchronized with the iDRAC/CMC path.
A table is displayed providing information about the successful location update. If the update is not
successful, you can view the application logs for details about the failure.

Chained PDU Support
In a data center, you can use any number of PDUs for power distribution, depending on the
infrastructural requirements. The PDUs can be connected in a daisy chain manner to further enhance and
improve the power distribution in the data center. In the daisy chain arrangement of PDUs, a master PDU
discovers and monitors the subordinate PDUs. Currently, only the master PDUs are discovered, but the
subordinate PDUs connected are not discovered, hence monitoring the power aspects of those PDUs are
not possible.
Starting OMPC 3.2, you can also discover, monitor, and perform all operations on the subordinate PDUs
as it is done on a master PDU. The daisy chained PDUs are discovered using the IP address, irrespective of
whether the same SNMP port is used (for both master and the subordinate) or not. Adding a daisy
chained PDU to a rack automatically associates the subordinate PDUs to that particular rack. However,
you can also associate or disassociate a subordinate PDU from the master PDU individually.
NOTE: If you disassociate a subordinate PDU from the master PDU, it is removed only from that
particular daisy chain arrangement.
NOTE: Deleting a master PDU does not delete the associated subordinate PDUs.
Viewing chained PDUs
1. In the left pane, click Devices → All Devices.
2. From the list of devices, select a PDU device.
3. If the selected PDU is a Master PDU, Associate Subordinate PDU option is displayed.

The sequence of the associated PDUs, PDU name, PDU model, Service tag, and the time of discovery
is displayed.
5. If the selected PDU is a subordinate PDU, Associate Master PDU option is displayed.
6. Click on the Associate Master PDU option to view the associated master PDU.
The PDU name, PDU model, Service tag, and the time of discovery is displayed.
Managing groups
OpenManage Power Center enables you to create groups for organizing devices, so that you can
manage them more efficiently. The groups can be of the following types:
