FortiGate-5140 chassis

Cooling fan trays

Cooling fan trays

The FortiGate-5140 chassis contains three interchangeable hot-swappable cooling fan trays installed at the front bottom of the chassis.

You can remove any fan tray by lifting the front cable tray, pressing the hot swap button on the tray front panel, fully loosening the mounting knots, and then pulling the fan tray out using the extraction handle.

Each cooling fan tray contains two radial fans for cooling the modules installed in the FortiGate-5140 chassis. Fan speeds are monitored by a tachometer signal sent from the cooling fan trays to the shelf manager. The shelf manager regulates the fan speed by adjusting the DC voltage supplied to the fan trays.
