ILOM Overview
The Integrated Lights Out Manager (ILOM) firmware runs on the service processor
in the server, enabling you to remotely manage and administer your server.
ILOM enables you to remotely run diagnostics such as power-on self-test (POST),
that would otherwise require physical proximity to the server’s serial port. You can
also configure ILOM to send email alerts of hardware failures, hardware warnings,
and other events related to the server or to ILOM.
The service processor runs independently of the server, using the server’s standby
power. Therefore, ILOM firmware and software continue to function when the server
OS goes offline or when the server is powered off.
Note – Refer to the Integrated Lights Out Manager 3.0 Concepts Guide for
comprehensive ILOM information.
Faults detected by ILOM, POST, the Predictive Self-Healing (PSH) technology, and
the External IO Expansion Unit (if attached) are forwarded to ILOM for fault
handling (FIGURE: ILOM Fault Management on page19).
In the event of a system fault, ILOM ensures that the Service Required LED is lit,
FRUID PROMs are updated, the fault is logged, and alerts are displayed. Faulty
FRUs are identified in fault messages using the FRU name.
