Oracle Integrated Lights Out Manager (ILOM) is a low-level system management tool used to monitor and manage system components, diagnose problems, and manage the service processor. The service processor card acts independently of the host system, and is available when the main system power is shut down.
By default, the service processor is the gateway to the system, through its two ports: network management (NET MGT) and serial management (SER MGT). After initial installation, typically you connect an Ethernet cable from the network management port to your management network. This setup enables remote access to ILOM, which you can manage from either the command-line interface or the web interface.
For more information about ILOM, see the Oracle Integrated Lights Out Management Supplement for the SPARC Enterprise T5440 Server and the Integrated Lights Out Manager 3.0 Getting Started Guide.
