SCSI Termination
The VXIpc 870 Series uses active termination on the SCSI-3 bus. Because
the VXIpc 870 Series is always an end device, you should not need to
disable the termination; however, for informational purposes Figure 3-5
shows the jumper settings for both enabled and disabled termination.
Figure 3-5.
SCSI Termination
System CMOS
The VXIpc 870 Series contains a backed-up memory used to store BIOS
defaults and configuration information:
To clear the CMOS contents:
1.
Place the jumper as shown in Figure 3-6b to short the pins of W6.
Caution
Do
not
keep these two pins shorted because the CMOS memory cannot be
sustained when the power is turned off in this state.
2.
Power-on the VXIpc 870 Series. The screen should briefly appear,
and then go black.
3.
Power-off the VXIpc 870 Series.
