Turning The Module On And Off; Nmi Switch; Fim-7901E Hardware Architecture - Fortinet FortiGate-7000E Series Manual

FIM-7901E interface module

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.
l
One 1Gbps base backplane channel for base backplane communication with the FPMs.
l
One 40Gbps fabric backplane channel for fabric backplane communication with the other FIM.
l
One 1Gbps base backplane channel for base backplane communication with the other FIM.
