Troubleshooting
If you are experiencing problems with the RocketPort Universal PCI, review the
troubleshooting procedures for your system before calling Technical Support.
Before Calling Technical Support
Review the following information before calling Technical Support because they
will request that you perform many of the procedures or verifications before they
will be able to help you diagnose a problem.
• Verify the cabling using Connecting Serial Devices on Page 11.
Note: Most customer problems reported to Comtrol Technical Support are
eventually traced to cabling or network problems.
• If you have not done so, run the diagnostics ( RocketPort Universal PCI
Diagnostics on Page 21).
• Verify that you have installed the latest RocketPort Universal PCI device
driver, see
Locating the Latest Drivers and Documentation on Page 6.
If necessary, remove or update the existing driver using the procedures in the
RocketPort Universal PCI Device Driver Installation Guide for Windows or
README file packaged with the FreeBSD, Linux, QNX, or SCO OpenServer
driver.
If none of the above work, you can refer to one of these subsections:
• Troubleshooting Windows Systems on Page 23
• Troubleshooting Linux Systems on Page 31
RocketPort Universal PCI Diagnostics
This subsection describes how to create and run the bootable diagnostic to verify
that the RocketPort Universal PCI hardware is functioning properly. The
RocketPort Universal PCI is shipped with a bootable diagnostic on the Software
and Documentation CD that executes hardware diagnostics.
You can use the diagnostic to:
• Confirm that the hardware is functioning
• Determine resolutions to conflicts during installation
• Perform a stress test on all RocketPort Universal PCI ports in the system
The diagnostic requires a loopback plug to test a port or ports. A single loopback
plug is shipped with the RocketPort Universal PCI. You can build additional
loopback plugs or move the loopback plug to the port you want to test. See
Connecting Serial Devices on Page 11 if you want to build loopback plugs.
