Cooling air flow and required minimum air flow clearance
When installing the FortiGate-6000F, make sure there is enough clearance for effective cooling air flow. The following diagram shows the cooling air flow through the FortiGate-6000F and the location of fan trays. Make sure the cooling air intake and warm air exhaust openings are not blocked by cables or rack construction because this could result in cooling performance reduction and possible overheating and component damage.
FortiGate-6000F cooling air flow and minimum air flow clearance (appliance side view)
All cool air enters the appliance through the front panel and all warm air exhausts out the back. For optimal cooling allow 100 mm of clearance at the front and back of the chassis. This results in a total footprint of 850 mm from front to back. Side clearance is not required.
