Ethernet Port LEDs
Note – The NET MGT port operates only in 100-Mbps or 10-Mbps so the speed
indicator LED can be green or off (never amber).
1.4 Using the Service Processor Firmware for
Diagnosis and Repair Verification
The Sun Integrated Lights Out Manager (ILOM) firmware is a service processor in
the server that enables 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.
