CHAPTER 2 –Hardware Installations

CPU Installation:

The SPI-6941-LV Industrial CPU Card supports a single Intel
®
or Pentium III processor (FC-PGA or FC-PGA2). The CPU core voltage is automatically
adjusted by the voltage regulator on the CPU card, which is connected to the VID pin of the
processor. The processor's VID pins automatically program the voltage regulator on the CPU
card to the required processor voltage. The host bus speed is automatically selected. The
processor connects to the CPU card through the 370-pins ZIF PPGA socket.
Please change the setting of JP12 in case that you use the CPU other than Tualatine
CPU (PC686-1260). See page 37.
The CPU card supports the processors listed in table below:
Processor Speed
566 MHz to 850MHz
Processor Speed
1.0GHz to 1.2GHz
Processor Speed
500 MHz to 866MHz
Processor Speed
1.13GHz to 1.26GHz
The ZIF PPGA socket comes with a lever to secure the processor. Make sure the notch
on the corner of the CPU corresponds with the notch on the inside of the socket.
After you have installed the processor into the socket 370, check if the configuration
setup for the CPU type and speed are correct. The CPU should always have a Heat Sink and a
cooling fan attached to prevent overheating.
Note: Ensure that the CPU heat sink and the CPU top surface are in total contact to avoid CPU
overheating problem that would cause your system to hang or be unstable.
