Features of the AlphaPC164UX Motherboard
Power Requirements
2.1 Power Requirements
The AlphaPC 164UX motherboard requires a minimum of a 300 watt power supply.
The power supply must be ATX-compliant.
Caution:
Fan sensor required.
The 21164 microprocessor cooling fan
must
have a built-in sensor that will drive a signal if the airflow stops. The
sensor is connected to the motherboard connector J35. When the signal
is generated, the speaker generates a tone..
2.2 Environmental Requirements
The 21164 microprocessor is cooled by a small fan blowing directly into the chip’s
heat sink. The AlphaPC 164UX motherboard is designed to run efficiently using
only this fan. Additional fans may be necessary depending upon cabinetry and the
requirements of add-in cards and disk drives.
The AlphaPC 164UX motherboard is specified to run within the environment listed
in Table 2–4.
