TheApplication Guide for the switch module provides more details abouttroubleshooting the switch module.If you cannot locate and correct a problem by using the information in this section,see Appendix A, “Getting help and technical assistance,” on page 33.Running POSTTo ensure that it is fully operational, the switch module processes a series of testsduring power-up or a restart (power-on self-test, or POST). These tests takeapproximately 1 minute to complete. The management module reads the testresults and displays them for you. During normal operation, these tests arecompleted without error, and the green OK LED is lit. However, if the switchmodule fails POST, the amber switch-module error LED and the system-error LEDon the BladeCenter unit are lit. An event is stored in the event log in the systemstatus panel of the management module. The specific failure is displayed on thesystem status I/O module panel of the management module.Note: For the locations and descriptions of the switch module LEDs, see Chapter 6,“Information panels, LEDs, and external ports,” on page 25.POST errorsThere are two types of errors: noncritical and critical.
