PC Server 325 POST beep and no beep error code listing
Resolving The Problem
Always start with 'General Checkout'
The Symptom-to-FRU Index lists beeps, errors, symptoms, and the possible causes. The most likely cause is listed first. Use this Symptom-to-FRU Index and the Symptom-to-FRU Index (QAPlus/PRO) in the PS/2 Hardware Maintenance Manual to help you decide which FRUs to have available when servicing the computer.
NOTE:
For IBM devices not supported by the QAPlus/PRO diagnostics code, refer to the manual for that device.

| Possible software and hardware mismatch problems. (Not repairable by replacing FRUs) | "Software/Hardware Mismatch Problems". |
| Memory Configuration Problems | "Memory". |
| Replacing the system board does not correct the problem. | See "System/Processor Board Replacement". |
