Sensors Reference Information

The server includes a number of sensors that generate entries in the system event log (SEL) when they cross a threshold. Many of the sensor readings are used to adjust the fan speeds and perform other actions, such as illuminating LEDs and powering off the server.

This section describes the following sensors:

Power Supply Sensors

lists the power supply sensors.

The system normally has two power supply modules, PS0 and PS1. All sensors are located under /SYS/PSn except for /SYS/VPS.
