### NAME

ipmi - Intelligent Platform Management Interface driver

### SYNOPSIS

ipmi0 at mainbus?

### DESCRIPTION

The ipmi device driver supports motherboards implementing the Intelligent Platform Management Interface version 1.5 or 2.0, and exports sensors and the watchdog through the envsys(4) interface.

### EVENTS

The ipmi driver is able to send events to powerd(8) when sensor's state has changed. Intrusion sensors will send a critical event when state is not ok. Power Supply sensors will send a critical event when the Power Supply unit is not installed and warning-over when the Power Supply unit is installed but not powered on. Fan, temperature and voltage sensors will send critical-over or critical-under when the value is very critical, or warning-over or warning-under if it's in a warning alert.
