Cooling Air Flow And Required Minimum Air Flow Clearance - Fortinet FortiGate-7060E System Manual

FortiGate-7060E Chassis
During normal chassis operation, all three fan trays are active and the fan speed is controlled by the active
management module. Fan trays are hot swappable. You can replace a failed fan tray while the chassis is
operating. To replace a fan tray, unscrew the four retention screws and use the handles to pull the fan tray out of
the chassis.
Install a replacement fan tray by sliding it into place in the empty slot and tightening the retention screws. As you
slide the new fan into place it will power up and the fan tray LED will light.
The other fan trays will continue to operate and cool the chassis as a fan tray is being removed and replaced.
However an open fan tray slot will result in less air flow through the chassis so do not delay installing the
replacement fan tray.

Cooling air flow and required minimum air flow clearance

When installing the chassis, make sure there is enough clearance for effective cooling air flow
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.

Most cool air enters the chassis through the chassis 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 and 50 mm of clearance at the
sides. Under these conditions 80% of cooling air comes from the front panel air intake and 20% from the left and
right side panels and 100% exits out the back. Side clearance is optional and chassis cooling will be sufficient if
no side clearance is available.
