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 sections describes the following sensors:

Power Supply Sensors

Temperature Sensors

Voltage Sensors

Fan Sensors

Disk Drive (HDD) Sensors

Fault LEDs

Power Supply Sensors

TABLE 1 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.

For example, /SYS/PS0/PRSNT is the power supply 0 presence indicator.

Fan Sensors

TABLE 4 lists the temperature sensors.

Fan sensors report the conditions of the system fans. For all fan sensors:

FBn is fan board 0 or 1.

FMn is fan module 0 or 1 on FB0.

Fn is a fan 0 or 1 on the fan module.
