CHAPTER 2
2.2CPU Installation:
The SYS7180VE Industrial CPU Card supports a single Intel® P4 CeleronTM or Celeron DTM processor and Pentium 4TM 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
The CPU card supports the processors listed in table below:

After you have installed the processor into the socket 478, 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.
