Troubleshooting Procedures
The following table provides troubleshooting procedures for some common problems.
For problems not addressed in the table, use the following guidelines.
Š Computer components are all interrelated. That is, a “video” problem may be
caused by the disk controller. The simplest diagnostic technique involves
replacing the suspect component with a new one.
Š Was the system working prior to a change? The change may need a different
configuration or may be faulty.
Š Check for loose connections in drive cables, power cables to fans, and disk-drive
cables.
Š Occasionally, Flash BIOS can be corrupted by hardware or software. Check the
Kontron Web site for the latest version of BIOS and follow the steps for reflashing.
Š When upgrading or adding hardware to an existing system, note board positions
and cables. Putting hardware in different slots and making connections in a
different order can change the functionality of a system.
Š Confirm jumpers and switch settings for all boards in the system are correct.
Verify with the individual product manuals the functions and settings of all
switches.
If these quick and simple steps fail to resolve the problem, contact Kontron Technical
Support for further advanced troubleshooting or reference the “Support” pages of the
Kontron Web site.
