Why can I not install Power Manager?

● If you have selected the online updates option in OpenManage Enterprise, check for the connectivity for the online path is
successful.
● If you have selected the offline updates option in OpenManage Enterprise, ensure that the
ome_powermanager_1.0.0.tar.gz folder has all the files for extension catalog with the sign file and the extension
installer packages, including the RPMs. The installation fails if there is a mismatch between the catalog and .tar files.
Why can I not disable or uninstall Power Manager?

Resolution: Disable the active policies and EPR option and then try to disable or uninstall Power Manager.
Why are policies being disabled when too many policies are
selected for deletion or disable or enable?

disabled on the User Interface (UI) until the action is complete. After the job is complete, there are entries to the audit logs for
these actions.
Why cannot I remove some devices or groups from Power
Manager?
Cause: If you have applied Emergency Power Reduction (EPR) option on the device or a group, then you cannot remove the
device or group from Power Manager.
Resolution: Disable the EPR option on the device or group, and then remove them from Power Manager.
Why is Power Manager not listed on Console and
Extensions page?
Cause: Power Manager may not be listed due to the following reasons:
● The offline share folder is not accessible
● Power Manager extension and tar folders are not present in the offline share folder
● If the extension catalog file is edited, then the signature files get corrupted.
Resolution: Ensure that the offline share folder is reachable through OpenManage Enterprise with the following files:
● ome_powermanager_1.0.0.tar.gz
● plugins_catalog
● plugins_catalog.json.asc
Also, download the plugins_catalog file and replace it with the corrupt file.
