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.

Eighteen front panel 100GigE QSFP28 fabric
channel data interfaces that can be connected to
100Gbps data networks to distribute sessions to
the FPMs in chassis slots 3 and up. The speed of
these interfaces can be changed to 40Gbps.
These interfaces can be split into four interfaces.
Each split interface can operate at 25Gbps or
10Gbps.
