I bought a X5SSE-GM board and SC811 IDE chassis and built them as your 1U server 5013S-i. When I power on the server, I get no display but only beeping noise.
The motherboard inside 5013S-I is X5SSE-GM+ which is different from X5SSE-GM. We suggest customers to buy our complete server instead of building by themselves. However, if you have already bought a X5SSE-GM board, please contact our RMA department, we will upgrade the board to X5SSE-GM+ for you.
