Reset HP iLO 2 of your HP Proliant or Blade Server

Integrated Lights-Out 2, or iLO2 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 2  can remotely perform most functions that otherwise require a visit to servers at thedata center, computer room or remote location.

HP Integrated Lights-Out 2 (iLO) is a hardware component on the HP server. This is a card/chip  which is usually integrated to the system board. You do not need an Operating System for iLO2 to work. It is on Hardware level. iLO2 has it’s own network connection and IP, and through it you can take remote of the server and use it.
