Splitting the FIM-7904E B1 to B8 interfaces

Each 40GE interface (B1 to B8) on the FIM-7904Es in slot 1 and slot 2 of a FortiGate-7000 system can be split
into 4x10GBE interfaces. You split these interfaces after the FIM-7904Es are installed in your FortiGate-7000
system and the system us up and running. You can split the interfaces of the FIM-7904Es in slot 1 and slot 2 at
the same time by entering a single CLI command. Splitting the interfaces requires a system reboot so Fortinet
recommends that you split multiple interfaces at the same time according to your requirements to avoid traffic
disruption.
For example, to split the B1 interface of the FIM-7904E in slot 1 (this interface is named 1-B1) and the B1 and B4
interfaces of the FIM-7904E in slot 2 (these interfaces are named 2-B1 and 2-B4) connect to the CLI of your
FortiGate-7000 system using the management IP and enter the following command:
config system global
set split-port 1-B1 2-B1 2-B4
end
After you enter the command, the FortiGate-7000 reboots and when it comes up:
The 1-B1 interface will no longer be available. Instead the 1-B1/1, 1-B1/2, 1-B1/3, and 1-B1/4 interfaces will be
l
available.
The 2-B1 interface will no longer be available. Instead the 2-B1/1, 2-B1/2, 2-B1/3, and 2-B1/4 interfaces will be
l
available.
The 2-B4 interface will no longer be available. Instead the 2-B4/1, 2-B4/2, 2-B4/3, and 2-B4/4 interfaces will be
l
available.
You can now connect breakout cables to these interfaces and configure traffic between them just like any other
FortiGate interface.
FIM-7904E hardware schematic
The FIM-7904E includes an integrated switch fabric (ISF) that connects the front panel interfaces to the DP2
session-aware load balancers and to the chassis backplanes. The ISF also allows the DP2 processors to
distribute sessions amoung all NP6 processors on the FPM modules in the same chassis.
