Document revision history Revision Date A00 April 2025 Description Initial release version 3.5 Product description OpenManage Enterprise Power Manager is a plug-in to OpenManage Enterprise. It uses fine-grained instrumentation to provide increased visibility to power consumption, carbon emissions, system anomalies, and resource utilization on servers. With Power Manager, you can efficiently: Monitor devices, static groups, physical groups, system profile, workload profile, virtual machines, and virtual machine groups. Receive alerts and generate reports about thermal events in servers, chassis, and custom groups consisting of servers and chassis. This reporting enables increased control, faster response times, greater accuracy, and broader decision-making intelligence than is otherwise possible. Monitor device metrics using parallel coordinate visualization. For more information about the user documentation, see the OpenManage Enterprise Power Manager product support page on Dell support site. 1 New features The following table describes the features and enhancements that are introduced with OpenManage Enterprise Power Manager 3.5.

Issues resolved in OpenManage Enterprise Power Manager 3.5 Issue ID Description N/A When you add a device in a Rack physical group, the minimum size you can allocate for a device is 1U. In a PowerEdge C-Series platform, you can accommodate two servers in 1U space. Hence, the space capacity calculations are not accurate when C-Series platform servers are added to a Rack physical group. Known issues The following high severity issues remain unresolved in this release: Table 4. Known issues in OpenManage Enterprise Power Manager 3.5 Issue ID Description Workaround Not available When you are trying to apply EPR on a device, the EPR operation may fail, and there is an entry in the Audit Logs. Ensure that all the following conditions are met: There is at least one device in the group that is eligible for applying EPR. Throttle option is applicable for the following devices: Server with iDRAC Enterprise license PowerEdge M1000e or PowerEdge MX7000 chassis Shutdown option is applicable only for servers. Not available After you reboot the OpenManage Enterprise appliance, if you try to perform any plug-in life cycle-related actions for Power Manager, the job is initiated in the backend but you still see the Console and Plugins page. And, the following message is displayed after some time: This page isn't working Wait for some time, and view the status. The plug-in life cycle-related action is completed successfully. Not available For an MX7000 chassis, the power cap limit is displayed as same as the upper bound value. When you manually change the power cap percentage, the value is not updated and even if you change the value, the percentage is not updated. Provide the power cap limit, and save the policy. The policy imposes the specified power cap limit on the selected devices or groups. 2 Table 4. Known issues in OpenManage Enterprise Power Manager 3.5 (continued) Issue ID Description Workaround Not available Events are not generated for the following combination of temperature threshold violations: Lower Warning to Upper Warning Lower Critical to Upper Critical Upper Warning to Lower Warning Upper Critical to Lower Critical Provide realistic warning and critical values so that there are no immediate alert generating temperature changes. Not available When you try to remove a device that is part of multiple groups using the REST API, then an error message is displayed. To remove a device that is part of multiple groups, remove the device from the group in OpenManage Enterprise. The changes are automatically reflected in Power Manager. Not available When devices are simultaneously added to and removed from a static group through OpenManage Enterprise, there are multiple entries of this update in the Audit Logs and Alert Log. Not available Not available When you change the power and temperature units To view the updates on the UI after changing the in Power Manager through REST APIs and check power and temperature units through REST APIs, for the unit change updates in the UI, the updates refresh the browser. are not reflected on the UI. Not available When you rediscover a device or an inventory job is in progress in OpenManage Enterprise, the following error message is displayed: Value entered for id is invalid Add the devices in Power Manager after the discovery or inventory job is completed. Not available After creating a physical group, you may not see Create New Physical Group, Edit Group, Manage Rack, Delete Group, or Attributes options when you right-click any group. Wait for some time or refresh the page, and then right-click the group. All the relevant options are displayed. 14527 The search results are not displayed in online help Not available for the Japanese language. Not available After you upgrade to OpenManage Enterprise version 3.6, discovery and inventory jobs run automatically, and if Redfish protocol is available for a device, the Redfish protocol takes precedence over WS-Man protocol and all operations for that device happen through Redfish protocol. And, Power Manager-specific capabilities are not supported for Redfish capable devices until Power Manager is upgraded to 2.0. Hence, devices that are Redfish capable are removed from Power Manager groups. To view the devices that are Redfish-capable after upgrading to Power Manager version 2.0: 1. Run Inventory in OpenManage Enterprise. 2. Click the Refresh Power Manager capabilities option on the Power Manager Devices page in Power Manager. Not available If you search for a PDU device in the global search Not available of OpenManage Enterprise when Power Manager is disabled, you can still view the PDU link in the search. However, if Power Manager is disabled, the PDU devices are not visible . Hence, after clicking the PDU link, you are redirected to the Devices page. 209489 Appliance upgrade time might be between 110 hours depending on the number of devices being monitored using Power Manager.
