When working with Fortinet Support to troubleshoot problems with FortiGate-5001B
boards with part number P10633-01 and up 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
board reboots. While the board is rebooting, traffic is temporarily blocked. The board
should restart normally and traffic can resume once its up and running.
The FortiGate-5001B base backplane 1-gigabit interfaces (base1 and base2) are typically
used for HA heartbeat or other management communication between FortiGate-5001B
boards installed in the same or in different FortiGate-5000 series chassis. You can also
configure FortiGate-5001B boards to use the base backplane interfaces for data
communication between FortiGate boards. To support base backplane communications
your FortiGate-series chassis must include one or more FortiSwitch-5000 series or other
1-gigabit base backplane switches installed in the chassis in base slots 1 and 2.
For information about base backplane communication in FortiGate-5000 series chassis,
see the FortiSwitch Backplane Communication
FortiSwitch-5000 series boards, see the FortiSwitch-5000 Series documents on the
FortiSwitch page of the Fortinet Technical Documentation website.
The FortiGate-5001B fabric backplane interfaces (fabric1 and fabric2) are typically used
for data communication between FortiGate-5001B boards installed in the same or in
different FortiGate-5000 series chassis. To support 10-gigabit fabric backplane
communications your FortiGate-5000 series chassis must include one or more
FortiSwitch-5003A or FortiSwitch-5003B boards or other 10-gigabit fabric backplane
switching boards installed in the chassis in fabric slots 1 and 2.

The FortiGate-5001B board includes two NP4 processors that provide accelerated
packet forwarding and policy enforcement for all FortiGate-5001B front panel and
backplane interfaces. Accelerated packet forwarding and policy enforcement results in
accelerated small packet performance required for voice, video, and other multimedia
streaming applications.
The following traffic scenarios are recommended for the accelerated interfaces:
• Small packet applications, such as voice over IP (VoIP).
The FortiGate-5001B accelerated interfaces provide wire speed performance for small
packet applications.
