POST Error Codes: A POST error code can occur in three ways:
1. Under the System Memory count at the upper-left corner of the screen.
Note: A memory error can appear without the memory count as a 203
address error.
2. After two beeps, followed by an error code and/or explanatory message.
3. As a sequence of beeps with no other messages or error codes
displayed.
Note: It may take a minute or more for the system to respond with
error messages or beeps.
If you have an XX62 error with no other error codes, run the Setup Utility
(see “Starting the Setup Utility” on page 1-16) and note any flagged options.
Note the XX62 error or flagged option and try to add it from the
Configuration Utility screen. If the option cannot be added, go to “Index of
Symptoms, Messages, Error Codes, or Beeps” on page 2-10 for additional
help.
If you want to print a copy of a Setup Utility screen on an attached printer,
press Print Screen while the screen is displayed.
How to Use Error Messages: Use the messages, error codes, and beep
combinations that occur to diagnose failures. If more than one failure
occurs, diagnose the first failure first. The cause of the first failure can result
in false messages, error codes, or beeps. If you did not receive any
messages, error codes, or beeps, see if the symptom is listed in “Index of
Symptoms, Messages, Error Codes, or Beeps” on page 2-10.
