9.5 How to View Temperature, Voltage, and
Fan Sensor Readings
This section explains how to view the Sun Fire X4100 or Sun Fire X4200 server
temperature, voltage, and fan sensor readings.
There are a total of six temperature sensors that are monitored. They all generate
IPMI events that will be logged in to the system event log (SEL) when an upper
threshold is exceeded. Three of these sensor readings are used to adjust the fan
speeds and perform other actions, such as illuminating LEDs and powering off the
chassis. These sensors and their respective thresholds are as follows:
■ Front panel ambient temperature (fp.t_amb)
■ Upper non-critical – 30 degrees C
