Viewing error logs from the diagnostic programs Start the diagnostic programs; select Hardware Info from the top of the diagnostic programs screen; select System Error Log from the list that appears; then, follow the instructions on the screen. See "Starting the diagnostic programs" on page 23 for more information. Light path diagnostics Many errors are first indicated by the illumination of the information LED or system-error LED in the operator information panel on the front of the server. If one or both of these lights are lit, one or more lights elsewhere in the server might also be lit and can direct you to the source of the error. This light path diagnostics feature provides a path that you can follow in three phases to help identify the source of an error. The lights are designed to be followed in an orderly progression, depending on the error. Note: Read "Safety information" on page 147 and "Handling static-sensitive devices" on page 30. The lights are viewed in the following order: 1. Begin on the front panel by checking the operator information panel. v The information LED indicates that information concerning a sub-optimal condition in the server is available in the system-error log. v The system-error LED indicates that an error has occurred. If the system-error LED on this panel is lit, go to step 2.

This label gives an overview of internal components that correspond to the LEDs on the light path diagnostics panel. This information, combined with the information in the table "Light path LED errors" on page 93, can often provide enough information to correct the indicated error. 18 IBM xSeries 365 Types 8861, 8862: Hardware Maintenance Manual and Troubleshooting Guide
