The default setting of these switches instructs the Switch to run the diagnostics one time at startup. If no fatal errors are encountered, the Switch places itself in normal operating mode. The diagnostics run at startup are the Power-On-Self- Test (POST) diagnostics.

These POST diagnostics check the entire Switch except for the GBICs. During the POST the Switch logs any errors encountered. Some of the POST errors are fatal (meaning that the Switch must not try to operate with that particular error) and some POST errors are non-fatal (meaning that the Switch can operate in a degraded mode until the problem can be corrected).
