IPMI Sensor Reference

A P P E N D I X A

Your server module includes a number of IPMI-compliant sensors and indicators. Sensors measure environmental values, such as voltages and temperature ranges, and detect when components are installed and removed. Indicators, such as Light-Emitting Diodes (LEDs), notify you of important server conditions, such as when service is required.

The IPMI interface limits sensor names to 16 characters. Sensor names must sometimes be shortened to fit this character limit. For example, /SYS is sometimes removed from the beginning of the path, or CMP0 might be abbreviated to P0.

This appendix contains two tables:

TABLE A-1 shows the sensors on your server module.

TABLE A-2 shows the indicators on your server module.
