Chapter 5 Troubleshooting
Diagnostic Testing
If you suspect that you are having hardware problems with your 4600 series, you
can use the Pro-face diagnostic utility to check out the PC’s various ports and
subsystems. The diagnostic utility is on the Documentation and Support Library
CD included with your unit.
Create Diagnostic Disk
The first task is to create a diagnostic diskette. The following steps can be done on
any computer with a CD-ROM drive and a floppy drive:
1. Create a DOS-bootable diskette.
2. Create a temporary folder on the computer hard drive.
3. There is a self-extracting zip file on the Documentation and Support Library CD
located in:
DRIVERS\Computer Diagnostics 99290-001\DOS\xydiag
Run that program and extract the files to the temporary folder you just created.
4. Copy the extracted files onto the DOS-bootable diskette. This diskette will be
inserted directly into the 4600 unit’s floppy drive.
Prepare the System
Before
starting the system tests, perform the following steps:
1. Place the CPU board jumpers and switches to the factory set positions. Refer to
Appendix D for these settings.
2. Plug the female end of the AC power cable into the side of the unit and the male
end into a properly grounded outlet.
3. Connect the serial loopback connector(s) and the printer cable to the appropriate
connectors, and connect a PC/AT or PS/2 keyboard. Figure 5-1 illustrates the
wiring necessary for the loopback connection.
4. Default the CMOS setup to the factory settings.
After completing all of the preceding steps, the 4600 unit is ready for diagnostic
testing. Follow the directions in the
Running the Tests
section of this chapter.
