FortiGate-7081F chassis
processors to load balance millions of data sessions over the FortiGate-7000F 400Gbps fabric backplane channel to
FPM processor modules. The FIM-7941F also includes a 50Gbps base backplane channel for base backplane
management communication with each FPM in the chassis, one 1Tbps fabric backplane channel for fabric backplane
communication with the other FIM in the chassis, and a second 50Gbps base backplane channel for base backplane
communication with the other FIM in the chassis. The FIM-7941F also includes two 4TByte SSD log disks in a RAID-1
configuration. The SSDs are accessible from the FIM-7941F front panel but should not be removed.
The FIM-7941F can be installed in any FortiGate-7000F series chassis in chassis hub/switch slots 1 or 2. The FIM-
7941F includes eighteen front panel 100GigE QSFP28 fabric channel data network interfaces (1 to 18) and two 400GigE
QSFP-DD fabric channel data network interfaces (19 and 20). Interfaces 1 to 18 can be connected to 100Gbps data
networks. Interfaces 19 and 20 can be connected to 400Gbps data networks. You can also change the interface type of
interfaces 19 and 20 and change the speeds of all of the data interfaces. You can split interfaces 1 to 20, M1, and M2.
The FIM-7941F also includes two 100 GigE QSFP28 base channel management interfaces (M1 and M2) and two 25
GigE SPF28 base channel management interfaces (M3 and M4). The management interfaces can be used for HA
heartbeat communication and session synchronization between two chassis in HA mode or for other management
functions such as remote logging. You can also change the speeds of the management interfaces. You can also split the
M1 and M2 interfaces.
The FIM-7941F includes a console port to provide console access to the FIM-7941F CLI.

The FIM-7941F interface module is an update of the FIM-7921F interface module with the
same architecture but a newer switch fabric that has a greater capacity and supports more
advanced features. You cannot include a FIM-7941F and FIM-7921F in the same chassis. In
an HA configuration, both chassis in the HA cluster must have the same FIMs.
