FWA-6171 NMC PCIe bus assignment

Purpose

FWA-6171 series has 8 x NMC (Network Mezzanine Card) slots for a wide range of GbE, 10GbE, 40GbE and 100GbE NMCs with or without Advanced LAN bypass.  Sometime manually set PCIe settings in BIOS would be required for some scenarios, the following PCIe port (NMC Bay) assignment may help customer understand which IOU settings should be touched.

Target Audience

All users which is using Advantech ICVG(CIoT) platforms, including FWA-6171 series
