Cooling
The NTDK91 Main Chassis and the NTDK92 Chassis Expander have forced
air cooling. As a result, you can install the chassis in a horizontal or vertical
position. The fan inside the chassis is controlled by heat. It runs at a reduced
speed at room temperature.
The Option 11C Mini universal power supply uses AC input. The power
supply is factory installed in the chassis. The power supply is not customer
replaceable. The Option 11C Mini system does not support DC input.
