Replacing fans

To replace the cooling fans, follow the procedure below:
1. Turn off the unit's power and unplug the power supply from its power source.
WARNING: Wait for 15 seconds after switching off the power. This is important as the
fans have no protective cover and the user can insert the fingers in the fans by
accident, you must wait until the fans have stopped completely.
