If you are unable to correct the problem using this index, go to "Undetermined problems" on page 75. Notes: v If you have both an error message and an incorrect audio response, diagnose the error message first. v If you cannot run the diagnostic tests or you get a diagnostic error code when running a test, but did receive a POST error message, diagnose the POST error message first. v If you did not receive any error message, look for a description of your error symptoms in the first part of this index. v Check all power supply voltages before you replace the system board (see "Power supply" on page 33). v Check the hard disk drive jumper settings before you replace a hard disk drive (see "Hard disk drive jumper settings" on page 21). Important: Some errors are indicated with a series of beep codes (see "Beep symptoms" on page 57). Type 2271/6840/6841 computers default to come up quiet (no beep and no memory count and checkpoint code display) when no errors are detected by POST. To enable beep and memory count and checkpoint code display when a successful POST occurs, do the following: 1. Select Start Options in the Configuration/Setup Utility program (see "Setup Utility program" on page 7). 2. Set Power-On Self-Test to Enhanced. The processor is a separate FRU from the system board; the processor is not included with the system board FRU. SIMM/DIMM/RIMM memory errors The following SIMM/DIMM/RIMM error messages are issued by the diagnostic programs. Error 2xx-1y A memory error was detected in SIMM socket Y. FRU/Action Replace the SIMM in the socket identified by the last digit of the error code. Re-run the test. If the same error code occurs again, replace the system board. © Copyright IBM Corp. 2000 37

The Symptom-to-FRU index lists error symptoms and possible causes. The most
likely cause is listed first. Always begin with Chapter 1, “General Checkout,” on
page 1. This index can also be used to help you decide which FRUs to have
available when servicing a computer. If you are unable to correct the problem
using this index, go to “Undetermined problems” on page 75.
Notes:
v
If you have both an error message and an incorrect audio response, diagnose the error
message first.
v
If you cannot run the diagnostic tests or you get a diagnostic error code when running a
test, but did receive a POST error message, diagnose the POST error message first.
v
If you did not receive any error message, look for a description of your error symptoms
in the first part of this index.
v
Check all power supply voltages before you replace the system board (see “Power
supply” on page 33).
v
Check the hard disk drive jumper settings before you replace a hard disk drive (see
“Hard disk drive jumper settings” on page 21).
Important:
Some errors are indicated with a series of beep codes (see “Beep symptoms” on page 57).
Type 2271/6840/6841 computers default to come up quiet (no beep and no memory count
and checkpoint code display) when no errors are detected by POST. To enable beep and
memory count and checkpoint code display when a successful POST occurs, do the
following:
1.
Select
Start Options
in the Configuration/Setup Utility program (see “Setup Utility
program” on page 7).
2.
Set
Power-On Self-Test
to
Enhanced
.
The processor is a separate FRU from the system board; the processor is not included with
the system board FRU.
SIMM/DIMM/RIMM memory errors
The following SIMM/DIMM/RIMM error messages are issued by the diagnostic
programs.
Error
FRU/Action
2xx-1y
A memory error was detected in SIMM
socket Y.
Replace the SIMM in the socket identified by
the last digit of the error code.
Re-run the test.
If the same error code occurs again, replace
the system board.
