Cooling fan trays

The FortiGate 6000F contains three hot swappable cooling fan trays installed in the back of the appliance. When the fan LED is green the fan tray is operating normally. If a fan tray LED turns red or goes off the fan tray should be replaced.

Cooling Fan Tray

Fan trays are hot swappable. You can replace a failed fan tray while the FortiGate 6000F is operating. To replace a fan tray, unscrew the four retention screws and use the handle to pull the fan tray out of the chassis. Install the new fan tray by sliding it into place. As you slide the new fan into place it will power up. Tighten the retention screws.

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 appliance so do not delay installing the replacement fan tray.

The FortiGate 6000F monitors the internal temperature of the appliance and adjusts the operating speed of the cooling fans as required. When the device is first powered on all cooling fans run at full speed. Once the system is up and running, the fan speeds are reduced to maintain an optimum temperature in the appliance.

During normal operation, all fan trays are active. If cooling requirements increase, the fan speed will increase.
