on page 101 for the location of the Processor Error LED.)
POST error codes and messages
The following table shows the error messages that can appear on the screen during
the power-on self-test (POST).
Notes:
1. In addition to the actions given for the messages, see “Troubleshooting” on
page 148 for general troubleshooting activities.
2. The actions for some of the messages require you to run the
Configuration/Setup Utility program. For information on using the
Configuration/Setup Utility program, see “Using the Configuration/Setup Utility
main menu” on page 21.
