HPE recommends using the Maintenance Window functionality within the HPE InfoSight portal to inform HPE Support of
upcoming maintenance windows.
Refer to https://infosight.hpe.com/dashboards/nimble/wellness/maintenance-windows for more information.
You can disable automated support case generation during planned maintenance from the Manage Maintenance Windows
page. After a maintenance window is set, no further communication with HPE Support is required.
Note:
Before you attempt to replace a power supply:
