The switch uses several configurable sensors and indicators to monitor switch power, voltage, and temperature.
The switch includes a sensor for each replaceable component. These sensors generate entries in the SEL when sensor thresholds are exceeded. Many of these readings are used to adjust the fan speeds and perform other actions, such as illuminating LEDs and powering off the switch.
You can also configure these sensors to generate IPMI PET and SNMP traps, as described in the Sun Integrated Lights Out Manager (ILOM) CLI Procedures Guide.
Caution - Do not use any interface other than the Oracle ILOM CLI or web interface to alter the state or configuration of any sensor or LED. Doing so could void your warranty.
You can view the system monitoring sensors and indicator parameters from the Oracle ILOM CLI or web interface.
