Integrated Lights-Out, or iLo, is an embedded server management technology exclusive to Hewlett-Packard but similar in functionality to the Lights out management (LOM) technology of other vendors.

iLO makes it possible to perform activities on a HP server from a remote location. The iLO card has a separate network connection (and its own IP address) to which one can connect via HTTPS. Possible options are:

* reset the server (in case the server doesn’t respond anymore via the normal network card)
* power-up the server (possible to do this from a remote location, even if the server is shut down)
* take over the screen
* mount remote physical CD/DVD drive or image.
* access the server’s IML (Integrated Management Log)
* remote console (in some cases however an ‘Advanced license’ maybe required for some of the utilities to work)
