Appendix A. Troubleshooting
A.1 Using the Serial Utilities CD-ROM
A serial utility CD-ROM is supplied with the adapter and will be used in the
troubleshooting procedures. By using this CD-ROM and following these simple
steps, most common problems can be eliminated without having to call Technical
Support.
1. Make sure the adapter is securely installed in a PCI slot.
2. Use the supplied CD-ROM (including the PDF file for this user manual) to
verify that the adapter is configured correctly.
3. Please refer to the CD-ROM for any manual updates and application-specific
information.
4. Always use the diagnostic software when troubleshooting a problem. This will
eliminate the software issue from the equation.
