Fortinet fortigate-5001a Hardwarehandbuch

The FortiGate-5020 chassis is a 4U 19-inch rack mount ATCA chassis that 
includes two slots to install up to two FortiGate-5000 series modules. You can 
install the same or different FortiGate modules in each slot. If both slots contain 
FortiGate-5001SX modules, the FortiGate-5020 chassis provides a total of 16 
Gigabit ethernet FortiGate interfaces.

If you install the same FortiGate-5000 series module in both slots, you can 
configure the modules to operate as an HA cluster. HA heartbeat communications 
between the modules uses the FortiGate-5020 backplane. No extra switching or 
other connections are required.

The FortiGate-5020 chassis can only be connected to AC power. Two redundant 
FortiGate-5020/5050 power supplies are factory installed in the FortiGate-5020 
chassis.
