Before You Begin

You can choose to view POST diagnostic and error messages locally on an attached terminal or remotely on an RSC console.

To view POST diagnostic 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 "About Setting Up a Console".

To view POST diagnostic messages remotely on an RSC console, you need to configure the RSC software before starting POST. For information about using the RSC software, see the Remote System Control (RSC) User's Guide.

By default, POST output is displayed locally on an attached terminal or through a tip connection. If your server has been reconfigured to display POST output on an RSC console, POST results will not display locally. To redirect POST output to the local system, you must issue the OpenBoot PROM command diag-output-to ttya from the RSC console. See the Remote System Control (RSC) User's Guide for additional details.

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 "How to Set the Diagnostic Level for POST and OBDiag".
