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." Jumper setting
information is given in Section 2, "System Configuration" and in Section 4, "System Board."
