8642 Corollary Error Codes

Corollary error codes can be displayed on the information panel during early portions of the POST code. If the system hangs with one of these checkpoints displayed, a Halt code may also be displayed, see FRU replacement is listed with the first FRU being the first item replaced and so on.

The types of Corollary Error Codes are:


Checkpoint Codes (CP) 1XX CP Codes

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 is displayed on the information panel:

   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

Test Point Codes (TP)

The following test points can be displayed on the information panel during early portions of the POST code. If the system hangs with one of these test points displayed, replace the FRU(s) in the order listed.

Test point information is displayed on the information panel like:

  TP: 1XXS      1XX Test point value, S Slot of card/board issuing error.

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" on page 385 and diagnose the beep symptom.

Test Error Indication (EP)

In some cases, the early POST code will detect errors during the running of the test cases and display corresponding test errors to the information panel. The information is displayed in the
following format:

   EP: 1XXS      1XX Error values as described below, S Slot number of the card/board issuing error.

EP Code FRU
1043 (104X) Memory Error
(First reseat memory adapter)
1. Memory Adapter
106s Processor Card Error 1. Processor Card


Multiprocessor Error Indication (IP and FP Codes)

During the early POST code, various multiprocessor bus errors might occur; if they do, the early POST code will display error information to the information panel in one of the following formats:

   IP: 1xx D S xx    OR    FP: 1xx D S xx

D Board/card issuing error : C-Processor, M-Memory, and B-Bridge.
  S Slot number of the board/card issuing the error.

If you receive an IP or FP error, do the following:

  1. Replace the board/card issuing the error.
  2. If replacing a FRU does not correct the problem, reinstall the FRU you removed from the computer; then, continue with the next step.
  3. Remove all cards/boards of the same type identified by the error code one at a time until you locate the failing card/board. (Example, if the error code identified a memory card and replacing the memory card in the slot identified by the error code does not correct the problem, remove all memory cards one at a time until you locate the failing board)

If the problem remains, replace the FRUs in the following order:

  1. Memory Card
  2. Processor Card
  3. Bridge Card
  4. System Board


Halt Indications (HALT)

If during the early POST code, a fatal error is detected, the system will display a "halting" message with a corresponding error code to indicate the reason for the halt condition. The message will be displayed on the information panel in the following format:

   HALT: XXXxxx

Where "XXX" is the following code number, replace the FRU(s) in the order listed. If present, ignore the last three digits (xxx).

Note: The exceptions to the above three or six digit error code format are:
   HALT: 02
   HALT: 107C
