8-2 Troubleshooting
This section provides information to help isolate and repair system malfunctions
at the field level. The system has a built-in program that automatically checks its
components when the system is powered on. If there is a problem, the system
displays an error message. If this happens, follow any instructions on the screen.
If screen messages do not help or an error message does not appear, refer to the
information in this section to help determine and correct the problem. For the
more common problems, refer to “Checklist” for assistance. If the information
in the checklist does not help, refer to “Diagnostics” for more detailed problem
solving.
If disassembly is required, see Section 3, “Disassembly and Reassembly.”
Connector pin assignments and jumper settings are given in Section 4, “System
Board” and in Section 5, “Riser Board.”
