User’s Manual
2.6.1 Clear CMOS (JP9)
If you encounter an abnormal condition that causes PXI-3920/
3910 to halt or fail to boot, clear the CMOS and restore the
controller BIOS to its default settings. To clear the CMOS,
locate the JP9 jumper on the board and shorten pin#2 and
pin#3. After you have cleared the COMS, restore the jumper by
returning to normal mode (shorten pin#1 and pin#2).
