4.2.2 Switch settings

The alarm board is designed to connect with up to 7 fans. User can set the

fan number by adjusting the switch, SW1, on the alarm board.

4.3 Thermal Sensor

There is a thermal sensor mounted on the right-wall plate, close to the

rear side of the chassis. The thermal sensor monitors the in-chassis tem-

perature. When the side temperature is overheated, the thermal sensor

sends a signal to the alarm board and a continuous alarm will be acti-

vated. To stop the alarm beep, press the Alarm Reset button on the front

panel. Figure 4.2 shows the layout of the thermal sensor module. The

default sensor I.D. number is 1. Users can refer to Section 4.4.1 Thermal

sensor number setting (see next page) to adjust the switch.
