2.10 Temperature Sensors
There are two temperature sensors inside the chassis. They are located at the rear section, attached to
the left and right upper corner of the chassis backplate. Refer to figure 2-10.
When the temperature rises, the sensors send a signal to the alarm board, and a continuous alarm is
sounded. To stop the alarm, press the alarm reset switch at the front panel.
Figure 2-10
Adjusting the temperature sensors
The temperature sensors can only be adjusted during installation of the CPU cards and add-on cards. If
you encounter difficulties when installing the cards because of the location of the temperature sensors,
you should do the following:
1. Remove the screw which secures the temperature sensor to the chassis.
2. Move the sensor away from its location. See figure 2-11.
3. Insert the card into the slot.
4. Return the temperature sensor back to its original location.
5. Re-attach the screw.
