+= GW9200
+
+The GW9200 does not require a PCIe switch for the FSA sites which offers great power and thermal savings. 
+
+= GW9400
+
+The GW9400 has 4 FSA sites, and thus needs some PCIe switches / hubs to feed PCIe to all of these sites. 
+
+The architecture is that the two PCIe channels coming from the i.MX95 each recieve a 1:2 switch (Microchip PCI12000C-I/ZUX)
+
+PCIe channel 1 goes to FSA 1 and 2
+PCIe channel 2 goes to FSA 3 and 4
+
+For orders of 100 pieces or more, the PCIe switches can be unloaded if PCIe is not needed on the FSA sites.
