FIM-7901E interface module

The FIM-7901E 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-7901E 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-7901E 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-7901E can be installed in any FortiGate-7000 series chassis in chassis hub/switch slots 1 or 2. The FIM-7901E provides thirty-two 10GigE small form-factor pluggable plus (SPF+) interfaces for a FortiGate-7000 chassis.

You can also install FIM-7901Es in a second chassis and operate the chassis in HA mode to provide chassis failover protection.

Mounting hardware

Use the module levers, power sliders, and secure screws to insert, secure and remove the module from the chassis.

Module levers

Carefully slide the module all of the way into the chassis slot and fully close the module levers to seat the module into the chassis slot and to connect the module to the chassis backplane connectors. When both module levers are fully closed, the power sliders can be lowered to their bottom position, locking the module levers and turning on power to the module.

Raise the power sliders to unlock the module levers and turn off module power. Then open the module levers to eject the module from the backplane connectors; allowing the module to be removed from the chassis.

The module lever mechanism helps reduce the engagement force required to insert or eject the module from the backplane connectors.

The module levers do not fully secure the module in the chassis. The secure screws must be tightened to reliably secure the module in the chassis and to make sure the module remains securely connected to the backplane for power and network connectivity.

Power sliders

Close the module levers and move the power sliders to their bottom position to lock the module levers and turn the module power switch on.

Move the power sliders to the top position to unlock the module levers and turn the module power switch off.

Gently push the power sliders down to make sure they are in their bottom position. If the module LEDs do not light the module is not receiving power. If this happens check the power sliders to make sure they are in their bottom position.

Secure screws

Fully tighten the secure screws to lock the module in the chassis providing a secure and reliable connection with the backplane.

Loosen the secure screws before ejecting the module from the chassis.

Front panel interfaces

You connect the FIM-7901E to your 10Gbps networks using the A1 to A32 front panel SFP+ 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.

Connector	Type	Speed	Protocol	Description
A1 to A32	SPF+	10Gbps/1Gpbs	Ethernet	Thirty-two front panel 10GigE SFP+ fabric channel interfaces. These interfaces are connected to 10Gbps networks to distribute sessions to the FPM processor modules installed in chassis slots 3 and up. These interfaces can also be configured to operate as Gigabit Ethernet interfaces using SFP transceivers. These interfaces also support creating link aggregation groups (LAGs) that can include interfaces from both FIM-7901Es.
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-7901Es 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.

Turning the module on and off

You can use the front panel power button to turn the FIM-7901E power on or off. If the FIM-7901E is powered on, press the power switch to turn it off. If the FIM-7901E is turned off and installed in a chassis slot, press the power button to turn it on.

NMI switch

When working with Fortinet Support to troubleshoot problems with the FIM-7901E you can use the front panel non-maskable interrupt (NMI) switch to assist with troubleshooting. Pressing this switch causes the software to dump registers/backtraces to the console. After the data is dumped the FIM-7901E reboots. While the FIM-7901E is rebooting, traffic is temporarily blocked. The FIM-7901E should restart normally and traffic can resume once the it is up and running.

FIM-7901E hardware architecture

The FIM-7901E 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-7901E 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.
