Symptom Check point
No Power
(FAN is not spinning)
* Make sure that no short circuit exists between the mainboard and chassis
* Check that all jumpers are set to their default positions.
* Check that the 115V/230V switch on the power supply is properly set.
* Check that the CPU is properly inserted in the CPU socket.
* Check that the power connector of the CPU fan is plugged in the correct position.
* Turn the power switch ON and OFF to test the system.
* Check the power of the battery on the mainboard.
(In general, the battery voltage is around 3VDC)
Able to power ON
the system (FAN is
spinning), but NO
screen display.
* Disconnect and remove all components from the mainboard except for the CPU,
memory modules, and the CPU fans.
* Check that the memory is Registered ECC DIMM. Refer to Appendix A:
Recommended Memory Modules or contact your authorized dealer for a list of
qualified memory vendors and models.
* Check that all jumpers are set to their default positions.
* Clear the CMOS through the Clear CMOS header.
* Check that the onboard VGA port and the monitor are properly connected.
* Check that you are using a 400 FSB CPU and PC2100/PC2700 (DDR266/DDR333)
Memory modules in the ServerBoard. If not, change the CPU to 400 FSB or memory to
PC2100/PC2700 (DDR266/DDR333) and try to power ON the system again.
* Use the onboard speaker to aide in determining the problem.
Memory Error(s) * Check that the memory DIMM modules are inserted properly into the DIMM sockets.
* Check to see if different speed memory modules are mixed in and used in the
ServerBoard memory banks. Verify that the BIOS setup is configured for the fastest
speed of RAM used. Arima recommends that you always install the same speed DDR
RAM in your system.
* Make sure all your memory modules in the ServerBoard are compliant with the
PC2100/PC2700 (DDR266/DDR333) Specifications and that they appear either in
Appendix A: Recommended Memory Modules or on your authorized dealer's Qualified
Vendor's List of Memory Modules.
