Configuring the PC
This section describes how to configure the following options on the PC:
•
SCSI termination
•
System CMOS
•
Ethernet power-on defaults
SCSI Termination
The VXI/VMEpc 600 Series uses active termination on the UW-SCSI bus.
Because the VXI/VMEpc 600 Series is always an end device, you should
not need to disable the termination; however, for informational purposes
Figure 3-12 shows the jumper settings for both enabled and disabled
termination.
Figure 3-12.
SCSI Termination
System CMOS
The VXI/VMEpc-650 contains a backed-up memory used to store BIOS
defaults and configuration information:
Follow this procedure to clear the CMOS contents:
1.
Place the jumper as shown in Figure 3-13b to short the pins of W20,
which is located on the CPU module.
Caution
Do not keep these two pins shorted because the CMOS memory cannot be
sustained when the power is turned off in this state.
