4-3. System Diagnosis
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.
Chipset POST Codes Table
In general, when circuit problems or inferior parts are found, the system in a specific code stops. The followings are error codes in each
part of the system.
