4. Troubleshooting
3) System Diagnosis
(1) System Diagnostics Card
The Diagnostics Card shows the system operations during the POST (Power On Self Test) in a
2 digit hexadecimal number by connecting the cable to the 10 pin connector below the PCMCIA slot
after separating the Top part. The card is used to evaluate the reason for the malfunction without
disassembling the system when the system malfunctions and to test if the system operates normally
after replacing a defective FRU.
(2) Debugging Code
In general, if a defect of the circuit or part is detected during the system test, the system stops at
a particular code. The error codes for each part of the system are listed in the following table.
