FIM-7941F 6.4.8 Interface Module Guide 4
Fortinet Technologies Inc.

FIM-7941F interface module
The FIM-7941F 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-7941F 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-7941F 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-7941F also includes two 4 TByte SSD log disks in a RAID-1
configuration. The SSDs are accessible from the FIM-7941F front panel but should not be removed.
The FIM-7941F interface module is an update of the FIM-7921F interface module with the
same architecture but a newer switch fabric that has a greater capacity and supports more
advanced features. You cannot include a FIM-7941F and FIM-7921F in the same FortiGate-
7000F chassis. In an HA configuration, both chassis in the HA cluster must have the same
FIMs.
The FIM-7941F can be installed in any FortiGate-7000F series chassis in chassis hub/switch slots 1 or 2. The FIM-
7941F 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. You can also split interfaces 1 to 20, M1 and
M2.
The FIM-7941F 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. You can also split the
M1 and M2 interfaces.
The FIM-7941F includes a console port to provide console access to the FIM-7941F CLI.

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.
FIM-7941F 6.4.8 Interface Module Guide 6

FIM-7941F interface module Fortinet Technologies Inc.
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-7941F to your 100Gbps data networks using the 1 to 18 front panel QSFP28 interfaces. You can
also connect the FIM-7941F to your 400Gbps data networks using the 19 and 20 front panel QSFP-DD interfaces. You
can create link aggregation groups that can include data interfaces from multiple FIMs and FPMs in the same chassis.
The front panel also includes M1 and M2 QSFP28, M3 and M4 SFP28 interfaces that connect to the base channel, two
Ethernet management interfaces (MGMT1 and MGMT2), and a USB port. The USB port can be used with any USB key
for backing up and restoring configuration files and installing and restoring firmware.

FIM-7941F 6.4.8 Interface Module Guide 9

FIM-7941F interface module Fortinet Technologies Inc.
Changing the FIM-7941F 1 to 18, M1, and M2 interfaces
By default, the FIM-7941F 1 to 18 (P1 to P18) , M1, and M2 interfaces are configured as 100GigE QSFP28 interfaces.
You can make the following changes to these interfaces:
lChange the interface speed to 40G using the config system interface command.
lSplit one or more of the interfaces into four 25GigE interfaces.
lChange the interface speed of one or more of the split interfaces to 10Gig.
You should configure split interfaces on both FortiGate-7000Fs before forming an FGCP HA
cluster. If you decide to change the split interface configuration after forming a cluster, you
need to remove the backup FortiGate-7000F from the cluster and change the split interface
configuration on both FortiGate-7000Fs separately. After the FortiGate-7000Fs restart, you
can re-form the cluster. This process will cause traffic interruptions.
You can use the following command to split the P3 interface of the FIM-7941F in slot 1 and the P16 and M1 interfaces of
the FIM-7941F in slot 2:
config system global
set split-port 1-P3 2-P16 2-M1
end
The FortiGate-7000F reboots and when it starts up:
lInterface 1-P3 has been replaced by four 25GigE CR2 interfaces named 1-P3/1 to 1-P3/4.
lInterface 2-P16 has been replaced by four 25GigE CR2 interfaces named 2-P16/1 to 2-P16/4.
lInterface 2-M1 has been replaced by four 25GigE CR2 interfaces named 2-M1/1 to 2-M1/4.
You can use the config system interface command to change the speeds of each of the split interfaces. You can
change the speed of some or all of the individual split interfaces depending on whether the transceiver installed in the
interface slot supports different speeds for the split interfaces.
For example, to change the speed of the 2-P16/3 interface to 10Gig:
config system interface
edit 2-P16/3
set speed 10000full
end
Changing the FIM-7941F 19 and 20 interfaces
By default, the FIM-7941F 19 and 20 (P19 and P20) interfaces are configured as 400GigE QSFP-DD interfaces. You can
make the following changes to one or both of interfaces:
lChange the interface speed to 400G, 100G, or 40G using the config system interface command.
lChange the interface type to 100GigE QSFP28.
lSplit the interface into four 100GigE CR2 interfaces.
lSplit the interface into four 25GigE CR or 10GigE SR interfaces.
FIM-7941F 6.4.8 Interface Module Guide 10

FIM-7941F interface module Fortinet Technologies Inc.
All of these operations, except changing the interface speed using the config system interface command,
require a system restart. Fortinet recommends that you perform these operations during a maintenance window and
plan the changes to avoid traffic disruption. For example, you can change interface types and split interfaces as a single
operation.
You should change interface types or split interfaces on both FortiGate-7000Fs before forming
an FGCP HA cluster. If you decide to change interface type or split interfaces after forming a
cluster, you need to remove the backup FortiGate-7000F from the cluster and change
interfaces as required on both FortiGate-7000Fs separately. After the FortiGate-7000Fs
restart, you can re-form the cluster. This process will cause traffic interruptions.
Changing the P19 or P20 interface type to 100GigE QSFP28
You can use the following command to convert the P19 or P20 interface to a 100GigE QSFP28 interface. To change the
interface type of P19 of the FIM-7941F in slot 1 (1-P19) and P20 of the FIM-7941F in slot 2 (2-P20) enter the following
command:
config system global
set qsfpdd-100g-port 1-P19 2-P20
end
The FortiGate-7000F reboots and when it starts up interface 1-P19 and 2-P20 are operating as 100GigE QSFP28
interfaces.
Splitting the P19 or P20 interfaces into four 100GigE CR2 interfaces
You can use the following command to split the P19 or P20 interfaces into four 100GigE CR2 interfaces. To split P19 of
the FIM-7941F in slot 1 (1-P19) and P20 of the FIM-7941F in slot 2 (2-P20) enter the following command:
config system global
set split-port 1-P19 2-P20
end
The FortiGate-7000F reboots and when it starts up:
lInterface 1-P19 has been replaced by four 100GigE CR2 interfaces named 1-P19/1 to 1-P19/4.
lInterface 2-P20 has been replaced by four 100GigE CR2 interfaces named 2-P20/1 to 2-P20/4.
Splitting the P19 or P20 interfaces into four 25GigE CR or 10GigE SR interfaces
You can use the following command to split the P19 or P20 interfaces into four 25GigE CR interfaces. The following
command converts the interface into a 100GigE QSFP28 interface then splits this interface into four 25 GigE CR
interfaces. To change P19 of the FIM-7941F in slot 1 (1-P19) and P20 of the FIM-7941F in slot 2 (2-P20) enter the
following command:
config system global
set qsfpdd-100g-port 1-P19 2-P20
set split-port 1-P19 2-P20
end
The FortiGate-7000F reboots and when it starts up:

lInterface 1-P19 has been replaced by four 25GigE CR interfaces named 1-P19/1 to 1-P19/4.
lInterface 2-P20 has been replaced by four 25GigE CR interfaces named 2-P20/1 to 2-P20/4.
If you want some or all of these interfaces to operate as 10GigE SR interfaces you can use the config system
interface command to change the interface speed. You can change the speed of some or all of the individual split
interfaces depending on whether the transceiver installed in the interface slot supports different speeds for the split
interfaces.
Turning the FIM-7941F on and off
You can use the front panel power button to turn the FIM-7941F power on or off. If the FIM-7941F is powered on, press
the power switch to turn it off. If the FIM-7941F 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-7941F 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-7941F reboots. While the FIM-7941F is rebooting,
traffic is temporarily blocked. The FIM-7941F should restart normally and traffic can resume once the it is up and
running.
FIM-7941F hardware architecture
The FIM-7941F includes an integrated switch fabric (ISF) that connects the front panel interfaces and the chassis fabric
backplane to the NP7 processors. The NP7 processors receive sessions from the FIM front panel data interfaces and
the FPM front panel data interfaces over the fabric backplane. The NP7 processors use SLBC to distribute sessions to
FPMs over the fabric backplane.
The FIM-7941F also includes the following backplane communication channels:
lTen 400Gbps fabric backplane channel to distribute traffic to the FPMs.
lTen 50Gbps base backplane channel for base backplane communication with the FPMs.
lOne 1Tbps fabric backplane channel for fabric backplane communication with the other FIM.
lOne 50Gbps base backplane channel for base backplane communication with the other FIM.

Hardware installation
This chapter describes installing a FIM-7941F interface module into a FortiGate-7000 chassis.
Installing QSFP-DD, QSFP28, QSFP+, SFP+, and SFP transceivers
You must install QSFP-DD, QSFP28, or QSFP+ transceivers into the FIM-7941F front panel 19 and 20 fabric channel
interfaces before connecting them to 400Gbps, 100Gpbs, or 40Gbps networks. You can install the transceivers before or
after inserting the FIM-7941F module into a chassis.
You must install QSFP28 or QSFP+ transceivers into the FIM-7941F front panel 1 to 18 fabric channel interfaces and the
M1 and M2 base channel interfaces before connecting them to 100Gbps or 40Gbps networks. You can install the
transceivers before or after inserting the FIM-7941F module into a chassis.
You must install SFP28 or SPF+ transceivers into the FIM-7941F M3 and M4 interfaces before connecting them to
25Gbps or 10Gbps networks.
To install transceivers
To complete this procedure, you need:
lA FIM-7941F
lTransceivers to install
lAn electrostatic discharge (ESD) preventive wrist strap with connection cord
FIM-7941Fs must be protected from static discharge and physical shock. Only handle or work
with FIM-7941Fs at a static-free workstation. Always wear a grounded electrostatic discharge
(ESD) preventive wrist strap when handling FIM-7941Fs.
Handling the transceivers by holding the release latch can damage the connector. Do not force
transceivers into their cage slots. If the transceiver does not easily slide in and click into place,
it may not be aligned correctly. If this happens, remove the transceiver, realign it and slide it in
again.
1. Attach the ESD wrist strap to your wrist and to an available ESD socket or wrist strap terminal.
2. Remove the caps from the cage sockets on the FIM-7941F front panel.
3. Hold the sides of the transceiver and slide it into the cage socket until it clicks into place.
FortiGate-7121F cable bracket kit
The FortiGate-7121F chassis includes an optional cable bracket kit that you can install to help manage the network
cables connected to FIMs and FPMs installed in the chassis.
FIM-7941F 6.4.8 Interface Module Guide 14

Hardware installation Fortinet Technologies Inc.
FIM-7941F mounting hardware
To install a FIM-7941F you slide the module into a hub/switch slot in the front of an FortiGate-7000 series chassis (either
slot 1 or 2) and then use the mounting hardware, described in Mounting hardware on page 6, to lock the module into
place in the slot. When locked into place and positioned correctly, the module front panel is flush with the chassis front
panel and connected to the chassis backplane.
To position the module correctly you must use the mounting hardware shown below for the right of the FIM-7941F front
panel. The mounting hardware on the left of the front panel is the same but reversed. The FIM-7941F mounting
hardware aligns the module in the chassis slot and is used to insert and eject the module from the slot.
On some FIM modules there may be very little clearance between the front panel interfaces
and the module lever on the right side of the FIM-7941F. In fact, you may have to remove
network connectors from some front panel interfaces to open the module lever. In most cases
you should remove all network connectors from the front panel before opening the module
levers to remove an FIM module from a chassis slot.

The FIM-7941F module levers align the module in the chassis slot and insert and eject the module from the slot. The
power sliders activate micro switches that turn on or turn off power to the module. When both sliders are raised, the
module cannot receive power. When the sliders are fully closed, the module can receive power if it is fully inserted into a
chassis slot.

Inserting a FIM-7941F module into a chassis
This procedure describes how to insert a FIM-7941F module into slot 1 or 2 of a FortiGate-7000 chassis. The procedure
includes photographs to illustrate the procedure steps. The photos were taken in one of Fortinet's hardware labs using a
generic module and FortiGate-7000 chassis.
FIM and FPM backplane connectors are shipped with a backplane connector protection label
and plastic cover. Before inserting the FIM or FPM module into the chassis slot, remove the
label and plastic cover and check the backplane connectors to make sure they are clean and
undamaged.
To install an FIMor FPM into a chassis, carefully slide the module all the way into the chassis
slot, close the module levers to seat the module into the slot, and tighten the secure screws to
make sure the module is fully engaged with the backplane and secured. You must also make
sure that the power sliders are fully closed by gently pushing them down.
Installation Highlights:
1. Remove backplane connector protection label.
2. Module levers must be closed.
3. Secure screws must be tightened.
4. Power sliders must be fully closed for the module to get power and start up.
If the module is not receiving power all LEDs remain off.
FIM-7941F modules are hot swappable. This procedure is the same whether or not the chassis is powered on.
Do not carry the FIM-7941F module by holding the module levers or secure screws. When
inserting or removing the FIM-7941F from a chassis slot, handle the module by the front panel.
The levers are not designed for carrying the module. If the levers become bent or damaged,
the FIM-7941F may not align correctly in the chassis slot.
To complete this procedure, you need the following equipment and tools:
la FIM-7941F
la FortiGate-7000 chassis with an empty slot
lan electrostatic discharge (ESD) preventive wrist strap with connection cord
la Phillips screwdriver
FIM-7941Fs must be protected from static discharge and physical shock. Only handle or work
with FIM-7941Fs at a static-free workstation. Always wear a grounded electrostatic discharge
(ESD) preventive wrist strap when handling FIM-7941Fs. Attach the ESD wrist strap to your
wrist and to an ESD socket or to a bare metal surface on the chassis or frame. (An ESD wrist
strap is not visible in the photographs below because they were taken in an ESD safe lab
environment.)
1. Remove the FIM-7941F module from its packaging.
The module levers are closed when you first remove a new module from its packaging.
FIM-7941F 6.4.8 Interface Module Guide 16

Hardware installation Fortinet Technologies Inc.
Module backplane connectors may be covered by a backplane connector protection label and plastic cover. Before
inserting the module into the chassis slot, remove the label and cover and check the backplane connectors to make sure
they are clean and undamaged.
2. Align the module with the chassis slot, slowly slide the module into the slot, stop at
about 1-2 inches from fully inserting it.

3. Unlock the left and right module levers by pushing the power sliders up until the
levers pop open.
Before sliding the final portion of the module into the chassis fully open both levers by pushing the power sliders up. Fully
open both levers to avoid damaging the lever mechanism. Damaging the levers can prevent the module from connecting
to power.

4. Continue pushing the module into the slot until the levers engage with the sides of
the chassis slot.
Insert the module by applying moderate force to the front faceplate (not the levers) to slide the module into the slot. The
module should glide smoothly. If you encounter any resistance, the module could be aligned incorrectly. Pull the module
back out and try inserting it again.

5. Close both levers by pushing them into contact with the module front panel.
Closing the levers draws the module into the chassis slot and connects the module rear connectors to the chassis
backplane. The design of the levers leaves gaps to compensate for tolerances. So even when the levers are fully closed,
the module may not be fully into position and in contact with the chassis backplane.

6. Tighten both secure screws to close the gap between the module and the chassis.
Begin by engaging the secure screws into the chassis tapped hole by hand and roughly tighten them. Then use a Phillips
screwdriver to fully tighten the two secure screws. Do not use a power screwdriver, because the high torque and speed
can damage the chassis or screw thread. After tightening both secure screws, the module is fully seated in the chassis
slot and the module connectors are fully in contact with the chassis backplane.
After tightening both secure
screws, the module is fully
engaged with the chassis.

7. Push down both power sliders to make sure the module power switch is on.
When the module is fully in position, the power sliders should drop down, lock the levers, and turn module power on.
Gently push both power sliders down to their bottom position to make sure they are fully closed.

Shutting down and removing a FIM-7941F module from a chassis
This procedure describes how to shut down and remove a FIM-7941F module from FortiGate-7000 chassis. The
procedure includes photographs to illustrate the procedure steps. The photos were taken in one of Fortinet's hardware
labs using a generic module and FortiGate-7000 chassis.
FIM-7941Fs are hot swappable. This procedure is the same whether or not the chassis is powered on.
