RE: POST failed when plug in PCI-E 8X network adapter
Hi, many thanks for your answer.
I understand that PCI-E gen 2 has different line code and bus frequency than Gen 3. However, I also installed a NI PCIe8375 (sine.ni.com/.../207823) that use PCI-E Gen 1 (same 8b/10b code line and even lower bus frequency). This card works fine in both slots of 7050 which means PCI-E 3.0 actually has downward compatibility for previous generation PCI-E.
The interesting thing is that Qlogic adapter actually works fine in a 7040 SFF without any further configuration.
I also tried to upgrade the BIOS to latest version, it doesn't help.
