.Dd July 30, 2026 .Dt ENVMON 4 .Os .Sh NAME .Nm envmon .Nd Sun Ultra and Fire environmental monitor .Sh SYNOPSIS .Cd "envmon* at ebus?" .Sh DESCRIPTION The .Nm driver provides support for the .Ql env-monitor sensor found on Sun Ultra 25/45 and Fire V215/V245 machines. On the Ultra machines, the sensor reports the front panel temperature. On the Fire machines, the sensor reports the front fan tray fan speeds, the fan fault indicator, the front panel temperature, the keyswitch indicators, and controls the front and rear status LED's.

On the Fire machines, the sensor reports the front fan tray fan speeds, the fan fault indicator, the front panel temperature, the keyswitch indicators, and controls the front and rear status LED's.
p Temperature, fan speeds, and indicators are reported via the .Xr envsys 4 framework, whilst LED's are exposed via the .Xr led 4 framework. The fan fault indicator has a value of .Em 0 in normal operation. If a fault is detected, the fan fault value will represent the numbers of the failed fan trays, .Em 1 for fan tray 0, .Em 10 for fan tray 1, and so on, to .Em 100000 for fan tray 5. .Sh SEE ALSO .Xr envsys 4 , .Xr intro 4 .Xr led 4 , .Xr envstat 8 , .Sh HISTORY The .Nm driver first appeared in .Nx 11.1 . .Sh AUTHORS The .Nm driver was written by .An Julian Coleman Aq Mt jcoleman (at] NetBSD.org .
