.Dd January 15, 2012 .Dt SATMGR 4 sandpoint .Os .Sh NAME .Nm satmgr .Nd driver for satellite processor, controlling power, front panel LEDs, and buttons .Sh SYNOPSIS .Cd "satmgr0 at eumb? unit 0" .Cd "satmgr0 at eumb? unit 1" .Sh DESCRIPTION This driver provides an interface to the .Tn NAS builtin satellite microprocessor which controls the power, front panel LEDs, and push buttons. Communication is performed through character sequences, whose definition and usage depend on the .Tn NAS product models.
p The device file
a /dev/satmgr can be written to control the satellite processor and the LEDs. Reading it will return single characters for button press events. This facility was designed to implement a .Tn NAS control .Tn CGI program.
p .Nm detects a soft power-off condition, which is triggered by holding the front panel power button pressed for several seconds. This driver can optionally invoke .Xr powerd 8 to get a finer control over the system shutdown procedure. It is capable of reporting a power-button-pressed event. Refer to the .Xr powerd 8 manual section for more details.
p .Tn NAS products supported by .Nm : l -bullet -compact t Buffalo LinkStation t Conceptronic CH3WNAS t D-Link DSM-G600 (Rev. B) t Iomega StorCenter t KuroBox t LevelOne FNS-5000B t QNAP TurboStation t Synology DiskStation .El .Sh SYSCTL VARIABLES The following .Xr sysctl 3 variables are available for .Tn "Kurobox/Linkstation" .Tn NAS products: l -tag -width indent t machdep.satmgr.hwwdog_enable Toggle the system watchdog on (1) or off (0). .El
p For the .Tn "Iomega StorCenter" the following variables have been defined: l -tag -width indent t machdep.satmgr.fan_low_temp Set the temperature below which the fan is turned off. t machdep.satmgr.fan_high_temp Set the temperature above which the fan is turned on. .El .Sh FILES l -tag -width /dev/satmgrX -compact t Pa /dev/satmgr communication interface to .Nm . t Pa /dev/power event notify channel to .Xr powerd 8 . .El .Sh SEE ALSO .Xr powerd 8 , .Xr sysctl 8 .Sh HISTORY The .Nm driver first appeared in .Nx 6.0 .
