FWA-6171 NMC PCIe bus assignment

Purpose

The FWA-6171 series features 8 NMC (Network Mezzanine Card) slots, accommodating a variety of GbE, 10GbE, 40GbE, and 100GbE NMCs, with or without Advanced LAN bypass. In certain scenarios, manual adjustment of PCIe settings in the BIOS may be necessary. The following PCIe port (NMC Bay) assignments can assist customers in identifying which IOU settings need modification.

Target Audience

All users who are using Advantech ICVG(CIoT) platforms, including FWA-6171 series
