FIM-7941F interface module
Fortinet Technologies Inc.
l
Interface 1-P19 has been replaced by four 25GigE CR interfaces named 1-P19/1 to 1-P19/4.
l
Interface 2-P20 has been replaced by four 25GigE CR interfaces named 2-P20/1 to 2-P20/4.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:
l
Ten 400Gbps fabric backplane channel to distribute traffic to the FPMs.
l
Ten 50Gbps base backplane channel for base backplane communication with the FPMs.
l
One 1Tbps fabric backplane channel for fabric backplane communication with the other FIM.
l
One 50Gbps base backplane channel for base backplane communication with the other FIM.
