Fan Control Documentation, Buffalo LinkStation Live

The cooling fan of the Linkstation can be controlled in speed in 4 steps. Also the rotating speed could be read out. In case you have a failure, in the #Hardware section, technical details and supplier links are documented.

Software Control

An extensive description of the /usr/local/bin/miconapl commands are in the file:
http://buffalo.nas-central.org/download/Uploads/OldUploads/LS_Pro_temporary/LSPro_Softw.rtf

With the function fan_set_speed [stop|slow|fast|full] the speed setting can be either set or read out:

root@NAS-100:~# /usr/local/sbin/miconapl -a fan_set_speed fast
or
root@NAS-100:~# /usr/local/sbin/miconapl -a fan_set_speed
#[miconapl.fan_set_speed]
fan_speed=slow

With the function fan_get_speed the rotations per minute could be read out:

root@NAS-100:~# /usr/local/sbin/miconapl -a fan_get_speed
#[miconapl.fan_get_speed]
fan_rpm=1800

Values:
stop = 0 rpm
slow = 1800 rpm
fast = 2500 rpm
full = 3500 rpm

With the function temp_get the temperature in degree celsius could be read out:

root@NAS-100:~# /usr/local/sbin/miconapl -a temp_get
#[miconapl.temp_get]
temp=33

As decribed in http://www.mztn.org/kpro_memo/kpro_micon.html the temperature (degree celsius) control looks like:

stop -  20
slow 20 25 
fast 25 35
full 35

2007-04-15 danmiles, Replacing Linkstation Fan Just finished changing out the fan in my Linkstation 250. A couple of notes on the instructions given elsewhere...

07-Jun-2008, 09:12 AM #19 rradarr Try some oil! Hi - I've had the same problem with my Linkstation, but I've managed to return it to it's original as-new silent running with a clean and a small drop of sewing machine light engine oil. I still took the unit apart first, used an air spray to remove the dust, and then carefully applied the oil into the hub. Saved me a fiver on the fan with p&p. By the way - don't use WD40; it's not suitable for this task.
