The FIM-7921F 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-7921F 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-7921F 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-7921F also includes two 4 TByte SSD log disks in a RAID-1 configuration. The SSDs are accessible from the FIM-7921F front panel but should not be removed.
The FIM-7921F can be installed in any FortiGate-7000F series chassis in chassis hub/switch slots 1 or 2. The FIM-7921F 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.
The FIM-7921F 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.
The FIM-7921F includes a console port to provide console access to the FIM-7921F CLI.
