iLO comes preconfigured with proLiant servers of the 300 series and above. A default iLO user account and password is included. iLO can be configured through several ways including:

• Browser-based configuration.
• iLO RBSU accessed using the F8 key during power-on self-test (POST).
• Remote scripted configuration.
• Local on-line and local scripted setup.

The iLO management tool allows a user to perform the following actions on the server remotely:

• Power on and power off the server.
• Restart the server.
• Monitor the server, regardless of the state of the server’s operating system.
• Measure power usage.
• Apply patches, firmware updates, and critical virus updates through virtual media and virtual folders.
• Access system event logs and the HP Integrated Management Log.

HP 100 series servers include the Lights-Out 100 Remote Management Option with limited features. HP iLO has now been replaced by Integrated Lights-Out Advanced (known as iLO2 and iLO3). The latest releases of HP Integrated Lights-Out 2 (iLO2) and Lights-Out 3 (iLO3) have simplified the server setup process and enabled remote power and thermal optimization. As of Aug 2011, the current firmware versions of iLO 2 and iLO 3 are 2.07 and 1.26, respectively.
