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 CIoT platforms, including FWA-6171 series

Checks:

CPU number	CPU2		CPU1
Chassis NMC sequence	NMC8	NMC7	NMC6	NMC5
PCIe port ID	IOU0 A/B	IOU0 C/D	IOU1 A/B	IOU1 C/D
CPU number	CPU2		CPU1
NMC sequence	NMC4	NMC3	NMC2	NMC1
PCIe port ID	IOU3 A/B	IOU3 C/D	IOU3 A/B	IOU3 C/D

In addition , for device connected to PCIe riser board inside chassis, it's assigned to CPU2 IOU3 

For some specific bandwidth settings, please go to BIOS Menu > Hardware > PCI Express Ports Configuration for each port control

*Socket 0 = CPU1

*Socket 1 = CPU2
