Hi everybody,
I have an issue with a Xeon Phi 3120A Coprocessor installed in a Dell Precision T5820 tower (Xeon W-2102 cpu). I plugged the coprocessor in a PCIe slot (16x), and I powered it with the 8-pin and 6-pin cables required. When I start up the system the coprocessor blue LED blinks (very fast, may be 8Hz), and the coprocessor fan runs continuously. However, the system does not get to boot, and apparently gets stuck before POST: the screen is black, and the keyboard is off.
I have double checked that 4G is enabled in the BIOS. I also tried to power the system without the graphic card (Nvidia NVS 315), but still the system won't start up. When the coprocessor is not plugged in, the system works fine.
Surely I am missing something. Any help is really appreciated.
Alessio
