Hardware requirements
Power supply:
Power supply fan must be controllable by mainboard (22Khz PWM signal with 3.3V) and needs a
sense-pin for rpm-measurement.
Fan sense:
2 ripples per rotation
Ripple pulse
width:
T low and T high > 0.6 ms
Number of
revolutions
at 100% PWM: maximum 14000 Rpm
at 50% PWM: minimum 800 Rpm
e.g.:
Siemens S26113-E425 or. E427
Fan:
The fan speed must be controllable from 6 - 12 V (start voltage: 12 V). Therefore the fan must have
a mechanical suitability as well as a 3-pole-plug with a sense-pin for rpm-measurement.
Fan sense:
2 ripples per rotation
Ripple pulse
width:
T low and T high > 0.6 ms
Current:
blocking fan at 12 V: 1.6 A
rotating fan at 6V / 12V: 0.3A / 0.6 A
number of
revolutions
at 12V: maximum 14000 Rpm
at 6V: minimum 800 Rpm
e.g.:
Papst type 412 F/2H as processor fan
Sensor for internal temperature:
Housing temperature is read by an onboard sensor.
CPU temperature is read by an onboard sensor but only with processors which have an integrated
temperature diode.
Sensor for external temperature:
Use only a Siemens Sensor: e.g. T26139-Y3718-V1
Intrusion logic:
Push-button (type: opener, if housing is open pins 1 and 2 are connected).
BIOS options
Please refer to BIOS description on the including CD-ROM (menu
Advanced System Management
).
