AOC-SIMPLP-3+ The “+” indicate KVM function, but when you check the mainboards compatibility, the “+” IPMI card is not listed (validated). This is because X7DWA-N, has a “A” in the model name. The “A” stands for desktop/workstation board. These boards have no onboard vga. Compatible onboard vga chip is necessary for KVM function. That is why it is not validated and will not work.
