The FortiGate 7030E is a 6U 19 inch rackmount 3-slot chassis with a 80Gbps fabric and 1Gbps base backplane designed by Fortinet. The fabric backplane provides network data communication and the base backplane provides management and synch communication among the chassis slots.

The FortiGate 7030E chassis is managed by a single management module that includes an Ethernet connection as well as two switchable console ports that provide console connections to the modules in the chassis slots. The management module controls chassis cooling and power management and provides an interface for managing the modules installed in the chassis. The standard configuration of the FortiGate-7030E includes one FIM (interface) module in chassis slot 1 and two FPM (processing) modules in chassis slots 3 and 4. The front panel also includes a sealed blank panel. Breaking the seal or removing the panel voids your FortiGate 7030E warranty.
FortiGate 7030E schematic
The FortiGate 7030E chassis schematic below shows the communication channels between chassis components including the management module (MGMT), the FIM (called FIM1) and the FPMs (FPM3 and FPM4).
The management module (MGMT, with Intelligent Platform Management Bus (IPMB) address 0x20) communicates with all modules in the chassis over the base backplane. Each module, including the management module includes a Shelf Management Controller (SMC). These SMCs support IPMB communication between the management module and the FIM and FPMs for storing and sharing sensor data that the management module uses to control chassis cooling and power distribution. The base backplane also supports serial communications to allow console access from the management module to all modules, and 1Gbps Ethernet communication for management and heartbeat communication between modules.
FIM1 (IPMB address 0x82) is the FIM in slot 1. The interfaces of this module connect the chassis to data networks and can be used for Ethernet management access to chassis components. The FIM includes DP2 processors that distribute sessions over the Integrated Switch Fabric (ISF) to the NP6 processors in the FPMs. Data sessions are communicated to the FPMs over the 80Gbps chassis fabric backplane.
FPM3 and FPM4 (IPMB addresses 0x86 and 0x88) are the FPM processor modules in slots 3 and 4. These worker modules process sessions distributed to them by the FIM. FPMs include NP6 processors to offload sessions from the FPM CPU and CP9 processors that accelerate content processing.
