The FIM-7910E 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-7910E 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-7910E 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-7910E can be installed in any FortiGate-7000 series chassis in chassis hub/switch slots 1 or 2. The FIM-7910E provides four C form-factor pluggable 2 (CFP2) interfaces for a FortiGate-7000 chassis. Using a 100GBASE-SR10 multimode CFP2 transceiver, each CFP2 interface can also be split into ten 10GBASE-SR SFP+ interfaces.
You can also install FIM-7910Es in a second chassis and operate the chassis in HA mode to provide chassis failover protection.
You connect the FIM-7910E to your 100Gbps networks using the C1 to C4 front panel CFP2 interfaces. The front panel also includes M1 and M2 SFP+ interfaces for the base channel, four Ethernet management interfaces (MGMT1 to MGMT4), and a USB port. The USB port can be used with any USB key for backing up and restoring configuration files.
|C1 to C4||CFP2||100Gbps/10Gbps||Ethernet||Four front panel 100GigE CFP2 fabric channel interfaces (C1 to C4). These interfaces are connected to 100Gbps networks to distribute sessions to the FPM processor modules installed in chassis slots 3 and up. Using 100GBASE-SR10 multimode CFP2 transceivers, each CFP2 interface can also be split into ten 10GBASE-SR SFP+ interfaces. These interfaces also support creating link aggregation groups (LAGs) that can include interfaces from both FIM-7910Es.|
|M1 and M2||SFP+||10Gbps/1Gbps||Ethernet||Two front panel 10GigE SFP+ interfaces that connect to the base backplane channel. These interfaces are used for heartbeat, session sync, and management communication between FIM-7910Es 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|
|MGMT1 to MGMT4||RJ-45||10/100/1000Mbps||Ethernet||Four 10/100/1000BASE-T copper out of band management Ethernet interfaces.|
|USB||USB 3.0 Type A||USB 3.0 USB 2.0||Standard USB connector.|
Each 100GE interface (C1 to C4) on the FIM-7910Es in slot 1 and slot 2 of a FortiGate-7000 system can be split into 10 x 10GBE SFP+ interfaces. You split these interfaces after the FIM-7910Es are installed in your FortiGate-7000 system and the system us up and running. You can split the interfaces of the FIM-7910Es in slot 1 and slot 2 at the same time by entering a single CLI command. Enabling, disabling, or changing the split interfaces configuration requires a system reboot. Fortinet recommends that you split multiple interfaces at the same time according to your requirements to avoid traffic disruption.
For example, to split the C1 interface of the FIM-7910E in slot 1 (this interface is named 1-C1) and the C1 and C4 interfaces of the FIM-7910E in slot 2 (these interfaces are named 2-C1 and 2-C4) connect to the CLI of your FortiGate-7000 system using the management IP and enter the following command:
config system global
set split-port 1-C1 2-C1 2-C4
After you enter the command, the FortiGate-7000 reboots and when it comes up:
- The 1-C1 interface will no longer be available. Instead the 1-C1/1, 1-C1/2, ..., and 1-C1/10 interfaces will be available.
- The 2-C1 interface will no longer be available. Instead the 2-C1/1, 2-C1/2, ..., and 2-C1/10 interfaces will be available.
- The 2-C4 interface will no longer be available. Instead the 2-C4/1, 2-C4/2, ..., and 2-C4/10 interfaces will be available.
You can now connect breakout cables to these interfaces and configure traffic between them just like any other FortiGate interface.
The FIM-7910E includes an integrated switch fabric (ISF) that connects the front panel interfaces to the DP2 session-aware load balancers and to the chassis backplanes. The ISF also allows the DP2 processors to distribute sessions among all NP6 processors on the FPM modules in the same chassis.
The FIM-7910E also includes the following backplane communication channels:
- One 80Gbps fabric backplane channel to distribute traffic to the FPMs.
- One 1Gbps base backplane channel for base backplane communication with the FPMs.
- One 40Gbps fabric backplane channel for fabric backplane communication with the other FIM.
- One 1Gbps base backplane channel for base backplane communication with the other FIM.
