# 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 a 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.

# SEE ALSO

# HISTORY

The `ipmi` driver first appeared in OpenBSD 3.9 and was then ported to NetBSD 4.0.

# AUTHORS

The `ipmi` driver was originally written by Jordan Hargrave and was ported to NetBSD by Manuel Bouyer ⟨bouyer@NetBSD.org⟩.
