FIM-7941F interface module

The FIM-7941F interface module is a hot swappable module that provides data, management, and session sync/heartbeat interfaces, base backplane switching, hardware acceleration, and fabric backplane session-aware load balancing for a FortiGate-7000F series chassis. The FIM-7941F includes an integrated switch fabric, five NP7 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 4 TByte SSD log disks in a RAID-1 configuration. The SSDs are accessible from the FIM-7941F front panel but should not be removed.

Note

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.

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.
