The FIM-7920E interface module is a hot swappable module that provides data, management, and session sync/heartbeat interfaces, base backplane switching, and fabric backplane session-aware load balancing for a FortiGate-7000 series chassis. The FIM-7920E includes an integrated switch fabric and DP2 processors to load balance millions of data sessions over the 80Gbps fabric backplane channel to FPM processor modules. The FIM-7920E also includes a 1Gbps base backplane channel for base backplane management communication with each FPM module in the chassis, one 40Gbps fabric backplane channel for fabric backplane communication with the FIM module(s) in the chassis, and a second 1Gbps base backplane channel for base backplane communication with the FIM module(s) in the chassis.
The FIM-7920E can be installed in any FortiGate-7000 series chassis in chassis hub/switch slots 1 or 2. The FIM-7920E provides four Quad Small Form-factor Pluggable 28 (QSFP28) 100GigE interfaces for a FortiGate-7000 chassis. Using a 100GBASE-SR4 QSFP28 or 40GBASE-SR4 QSFP+ transceiver, each QSFP28 interface can also be split into four 10GBASE-SR SFP+ interfaces.
