Cooling System and Airflow in an NFX150 Device

The NFX150 devices have front-to-back airflow. The air intake to cool the chassis is
located on the front of the chassis. Air is pulled into the chassis and pushed toward the
fans, which are built-in. Hot air exhausts from the rear of the chassis. See

Figure 16 on page 37

Power Supply in NFX150 Devices

NFX150 devices use a fixed, internal AC power supply. The power supply distributes
different output voltages to the device components according to their voltage
requirements. The power supply is fixed in the chassis and is not field-replaceable.

The power supply has a single AC appliance inlet that requires a dedicated AC power
feed. The AC power cord inlet is on the rear panel of the device.
