Viewing the test log The test log will not contain any information until after the diagnostic program has run. Note: If you already are running the diagnostic programs, begin with step 3. To view the test log: 1. Turn on the server and watch the screen. If the server is on, shut down the operating system and restart the server. 2. When the message F2 for Diagnostics appears, press F2. If a power-on password or administrator password is set, the server prompts you for it. Type in the appropriate password; then, press Enter. 3. When the Diagnostic Programs screen appears, select Utility from the top of the screen. 4. Select View Test Log from the list that appears; then, follow the instructions on the screen. The system maintains the test-log data while the server is powered on. When you turn off the power to the server, the test log is cleared. Diagnostic error message tables For descriptions of the error messages that might appear when you run the diagnostic programs, see "Diagnostic error codes" on page 125. If diagnostic error messages appear that are not listed in those tables, make sure that the server has the latest levels of BIOS, Advanced System Management Processor, ServeRAID, and diagnostics microcode installed. Light path diagnostics The server has LEDs to help you identify problems with some server components. These LEDs are part of the light path diagnostics built into the server. By following the path of lights you can quickly identify the type of system error that occurred. Power supply LEDs The AC and DC power LEDs on the power supply provide status information about the power supply. See "Installing a hot-swap power supply" on page 60 for Diagnostics 15
