I have serious trouble with a x3690. After moving it to a new server rack it won't startup.
After connecting the server to power supply the Light Path Diagnostic LEDs turn wheels. The normal behaviour would be that the power button blinks fast (4 times per second) and then goes into a slow blink, when you can start it.
I double checked every loose part (cables) and also checked RAM and powersupplies and power bridge.
I also tried to remove CMOS battery, as well as setting the jumpers to reset CMOS
I think that it is probaly the mainboard which is defect? Any ideas ?
