: Official documentation from Hewlett Packard Enterprise (HPE) on how to programmatically apply license keys using the Redfish API . Important Considerations
If you're running newer servers (Gen10 and Gen10+), note that iLO 5 and iLO 6 use a different licensing model. They offer more features in the Standard tier (including HTML5 KVM for 30 minutes per boot), and Advanced licenses are sold as subscriptions or perpetual. The same principles apply: avoid GitHub keys, use trials, or purchase legitimately.
Once you have a valid 25-digit key, follow these steps to activate it: to your iLO 4 web interface. Navigate to Administration in the left-hand sidebar. Select the Enter your Activation Key into the text boxes.
