System CMOS
The NI 8171 series contains a backed-up memory used to store BIOS
configuration information.
To clear the CMOS contents:
1. Turn off power.
2. Remove the controller from the chassis.
3. Move the jumper on J1 from pins 1-2 to pins 2-3 as shown in
Figure 2-2.
4. Wait 1 second. Move the jumper back to pins 1-2.
5. Reinstall the controller in the chassis.
Caution
Do not leave the jumper on pins 2-3. Doing so decreases battery life.
