FortiGate–3600C
The FortiGate-3600C features three NP4 processors:
- The 10Gb interfaces, port1-port4, and the 1Gb interfaces, port13-port17, share connections to one NP4 processor.
- The 10Gb interfaces, port5-port8, and the 1Gb interfaces, port18-port22 share connections to the second NP4 processor.
- The 10Gb interfaces, port9-port12, and the 1Gb interfaces, port23-port28 share connections to the third NP4 processor.

XAUI interfaces
Each NP4 processor connects to the integrated switch fabric through two XAUI interfaces: XAUI0 and XAUI1. On each NP4 processor all of the odd numbered interfaces use XAU0 and all of the even numbered interfaces use XAUI1:
NPU1
XAUI0 = port1,port3,port13, port15, port17
XAUI1 = port2, port4, port14, port16
NPU2
XAUI0 = port5, port7, port18, port20, port22
XAUI1 = port6, port8, port19, port21
NPU3
XAUI0 = port9, port11, port23, port25, port27
XAUI1 = port10, port12, port24, port26, port28
Usually you do not have to be concerned about the XAUI interface mapping. However, if an NP4 interface is processing a very high amount of traffic you should distribute that traffic among both of the XAUI interfaces connected to it. So if you have a very high volume of traffic flowing between two networks you should connect both networks to the same NP4 processor but to different XAUI links. So between even and an odd numbered FortiGate-3600C ports. For example, you could connect one network to port5 and the other network to port6. In this configuration, the second NP4 processor would handle traffic acceleration and both XAUI interfaces would be processing traffic.
FortiGate–3950B and FortiGate-3951B
The FortiGate-3950B features one NP4 processor. The 1Gb SPF interfaces, port1, port2, port3, port4, and the 10Gb SPF+ interfaces, port5, port6, share connections to one NP4 processor. The FortiGate-3951B is similar to the FortiGate-3950B, except it trades one FMC slot for four FSM slots. The network interfaces available on each model are identical.
You can add additional FMC interface modules. The diagram below shows a FortiGate-3950B with three modules installed: an FMC-XG2, an FMC-F20, and an FMC-C20.
- The FMC-XG2 has one SP2 processor. The 10Gb SPF+ interfaces, port1 and port2, share connections to the processor.
- The FMC-F20 has one NP4 processor and the twenty 1Gb SPF interfaces, port1 through port20, share connections to the NP4 processor.
- The FMC-C20 has one NP4 processor and the twenty 10/100/1000 interfaces, port1 through port20, share connections to the NP4 processor.
