FIM-7904E interface module

The FIM-7904E 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-7904E includes an integrated switch fabric and DP2 processors to load

balance millions of data sessions over the chassis fabric backplane to FPM processor modules.

The FIM-7904E can be installed in any FortiGate-7000 series chassis in hub/switch slots 1 and 2. The FIM-7904E

provides four Quad Small Form-factor Pluggable plus (QSFP+) interfaces for a FortiGate-7000 chassis. Using a

40GBASE-SR10 multimode QSFP+ transceiver, each QSFP+ interface can also be split into four 10GBASE-SR

interfaces.

You can also install FIM-7904Es in a second chassis and operate the chassis in HA mode with another set of

processor modules to provide chassis failover protection.

FIM-7904E front panel

The FIM-7904E includes the following hardware features:

Eight front panel 40GigE QSFP+ fabric channel interfaces (B1 to B8). These interfaces are connected to 40Gbps

networks to distribute sessions to the FPM processor modules installed in chassis slots 3 and up. Using 40GBASE-

SR10 multimode QSFP+ transceivers, each QSFP+ interface can also be split into four 10GBASE-SR interfaces.

These interfaces also support creating link aggregation groups (LAGs) that can include interfaces from both FIM-

7904Es.

Two front panel 10GigE SFP+ interfaces (M1 and M2) that connect to the base backplane channel. These

interfaces are used for heartbeat, session sync, and management communication between FIM-7904Es in different

chassis. These interfaces can also be configured to operate as Gigabit Ethernet interfaces using SFP transceivers,

but should not normally be changed. If you use switches to connect these interfaces, the switch ports should be

able to accept packets with a maximum frame size of at least 1526. The M1 and M2 interfaces need to be on

different broadcast domains. If M1 and M2 are connected to the same switch, Q-in-Q must be enabled on the

switch.

Four 10/100/10000BASE-T out of band management Ethernet interfaces (MGMT1 to MGMT4).

One 80Gbps fabric backplane channel for traffic distribution with each FPM module installed in the same chassis as

the FIM-7904E.
