7.3.1 Before You Begin

You can view POST diagnostic and error messages locally on an attached terminal.

To view POST diagnostic and error messages on the local system, you need to connect an alphanumeric terminal or establish a tip connection to another Sun system. For more information, see "2.10 About Communicating With the Server" or if you already have a console setup, see "7.4 How to Set Up a tip Connection".

You must verify baud rates between a system and a monitor or a system and a terminal. See "7.4.1 How to Verify the Baud Rate".

You can choose to run an abbreviated POST with concise error and status reporting or run an extensive POST with more detailed messages. For more information, see "7.7 How to Set the Diagnostic Level for POST and OBDiag".

If a console or a monitor is not connected to serial port A (default port) of a system to be tested, the keyboard LEDs are used to determine error conditions. See "7.12.1 Error Indications".
