Integrated Lights-Out, or iLO, is a proprietary embedded server management technology by Hewlett-Packard which provides out-of-band management facilities. The physical connection is an Ethernet port that can be found on most Proliant servers and microservers[1] of the 300 and above series.
iLO has similar functionality to the lights out management (LOM) technology offered by other vendors, for example Sun/Oracle's LOM port, Dell DRAC, the IBM Remote Supervisor Adapter and Cisco CIMC.
HP iLO licensing iLO standard features are included with every server to simplify server setup, perform health monitoring, monitor power and thermal control, and facilitate remote administration. ILO licenses activate functionality such as graphical Remote Console with multiuser collaboration, video record/playback, and many more features. Both HP Integrated Lights-Out (iLO) and HP Integrated Lights-Out 2 (iLO 2) consist of an intelligent. Renamed Remote Serial Console in iLO 2; however, the.

iLO makes it possible to perform activities on an 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:
iLO provides some other utilities like virtual media (CD, floppy), virtual power and a remote console. iLO is either embedded on the system board, or available as a PCI card.
iLO is embedded or available on some HP ProLiant and Integrity servers.
Prior to iLO, Compaq created several other lights out management products. The original was the Remote Insight Board (RIB), which was available as an EISA or PCIexpansion card. RIB was replaced with RILOE (Remote Insight Light-Out Edition), which was only available for PCI. The original RILOE was replaced with RILOE II. HP stopped manufacturing RILOE II in 2006. The final firmware version for RILOE is 2.53(A) dated 9 Mar 2004 and for RILOE II is 1.21 dated 5 July 2006.
For some ProLiant 100 series servers there is a 'Lights Out 100' option, which has more limited functionality. The LO100 is a traditional IPMIBMC, and does not share hardware or firmware with iLO.
There is also a version of iLO for HP Moonshot systems referred to as iLO Chassis Management which is often abbreviated as iLO CM. The Chassis Management version of iLO was derived from iLO 4.[2] As of June 2018 the most recent Chassis Manager Firmware available is version 1.56 which was released as part of the Moonshot Component Pack 2018.02.0.[3]
There have been multiple generations of iLO, each generation noted by a single digit number ('iLO 2'). Some generations of iLO are segmented into different editions, based on what features are licensed.[4] iLO includes updatable firmware, for which HP periodically releases new versions.
