System CMOS
The PXI-8150 contains a backed-up memory used to store BIOS
defaults and configuration information.
To clear the CMOS contents, short the pins of W1 as shown in
Figure 3-3b. Plug the unit back into the mainframe and apply power
momentarily. Turn the power back off and remove the unit. Place the
jumper back in the default state.
Caution:
Do not keep these two pins short-circuited. The computer cannot sustain
the CMOS memory when the power is turned off if you leave these two pins
shorted.

Ethernet Power-on Defaults
The PXI-8150 Ethernet circuitry loads its power-on settings from an
EEPROM. Do not change switch W1 from its default setting as shown
in Figure 3-4a. Figure 3-4b shows the alternate position only for
informational purposes.
