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.
