PC Server 720 - Checkpoint codes

Applicable to: World-Wide

Checkpoint Codes (CP)
The following checkpoints can be displayed on the information panel during early portions of the Power-On Self-Test (POST) code. If the system hangs with one of these checkpoints displayed, the FRU replacement should be as listed with the first FRU being the first item and so on.

The checkpoint code information is displayed on the information panel in the following format:

CP: 1XX

1XX Checkpoint values as described below.

Notes:
1. The checkpoint code will only be displayed by the default ( lowest slot number ) processor card. Therefore, only the default processor card is being tested during this time.
2. If a 2 digit checkpoint code (CP: XX) is displayed without a beep symptom, go to 'No Beep Symptoms— and diagnose the no beep symptom.
3. If a 2 digit checkpoint code (CP: XX) is displayed with a beep symptom, go to 'Beep Symptoms— and diagnose the beep symptom.
