Error Codes 200 - 299

Important: Go HERE to learn how to decode the last two digits of the 200-range error codes to determine which memory module is at fault. (Applies to Models 56/57, 76/77, 85, and 90/95.)

Symptom / ErrorFRU / Action

Reseat System Board Memory
1. System Board Memory
2. System Board
0002 0XXY / 0002 17XY
Memory Failure
If the 'Y' digit is in the range 'G' to 'V', suspect the model 90/95 processor board first.

See HERE how to decode the last two digits.
