Cooling air flow and required minimum air flow clearance

When installing the chassis, make sure there is enough clearance for effective cooling air flow. The following diagram shows the cooling air flow through the chassis and the locations 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.

Cool air enters the chassis through the chassis front panel and warm air exhausts out the back. For optimal cooling, allow 100 mm of clearance at the front and back of the chassis.
