The Integrated Lights Out Manager (ILOM) is system management firmware that allows you to manage your server when the host system is powered down. This is possible because the ILOM runs on a separate service processor (SP) that is powered by the host system’s standby power.
The ILOM also supports remote access to the host’s system console through a network remote keyboard, video and mouse (RKVM). The host’s I/O to optical and floppy drives can be redirected to real and virtual drives on the network. This allows a remote user to perform most maintenance operations, including installing an operating system.
For more information on ILOM, refer to the following documentation:
