Hi there,
From the error code that you are getting, it seems that the power supplies that you are using are not supported by this motherboard and the error indicates a 'Power fault: DC Power unexpectedly lost (power good drop out)'
Please make sure that all the components you are using are compatible and are on the tested hardware list for this motherboard. More information on tested hardware can be found on the following link: http://www.intel.com/support/motherboards/server/s5500bc/compat.htm
For testing purpose, please can you connect only basic components on the board (only power supply connectors, memory and processors and fans). Do not connect any hard disks, dvd drive or any other PCIe por PCIx cards yet. See if the system boots now.
Also as part of a good integration check that you have populate the memory slot properly corresponding to the cpu socket. Please refer to the motherboard manual for more information on memory population: http://download.intel.com/support/motherboards/server/s5500bc/sb/e42249006_s5500bc_tps_14.pdf
Hope this will be helpful to you.
Cheers.
Hi
Many thanks for your reply. We've tried all things to startup the mainboard, but all of them were
Hi
I am having the same problem. The machine is an S5500BC with a single 5520 processor and 4 x 2 GB of Kingston 1066 MHz ECC memory. In my case I have the SC5650D chassis with 600w PSU with the required 3.5A standby voltage.
The machine will start with freshly plugged in power but if it is shutdown either by the OS or the power switch I get the 1,5,4,2 beep code, an amber LED on the front of the box and no restart upon power up. It argues to me that there is a standby voltage switching problem either with the PSU or the motherboard.
Has anyone had any furtgher ideas on this?
TIA
Has anyone found the solution to this? I am having the same problem with a brand new system.
