Hot-plug power supply units

The BX900 S1 system unit has 6 bays for hot-plug power supply units
(PSU 1-6).
All bays for power supply units are fitted with flaps which close automatically.
This ensures sufficient cooling of the system components when you replace a
power supply unit or fan module during operation and when there are empty
bays.
