v No: Go to step 2. v Yes: Shut down all failing servers that are related to the cluster. Go to step 2. 2. Complete the following steps: a. Check the power supply LEDs, see "Power-supply LEDs" on page 142 b. Turn off the server and all external devices. c. Check all internal and external devices for compatibility at http://www.ibm.com/servers/eserver/serverproven/compat/us/. d. Check all cables and power cords. e. Set all monitor controls to the middle positions. f. Turn on all external devices. g. Turn on the server. If the server does not start, see "Troubleshooting tables" on page 126. h. Check the system-error LED on the operator information panel. If it is flashing, check the light path diagnostic LEDs on the system board (see "System-board LEDs" on page 15). i. Check for the following results: v Successful completion of POST, which is indicated by a single beep (see "POST" on page 107 for more information) v Successful completion of startup, which is indicated by a readable display of the operating-system desktop 3. Did a single beep sound and are there readable instructions on the main menu? Note: A single beep indicates successful completion of POST and is not an error. v No: Find the failure symptom in "Troubleshooting tables", if necessary, see "Solving undetermined problems" on page 177. v Yes: Run the diagnostic programs (see "Running the diagnostic programs" on page 144). - If you receive an error, see "Diagnostic error codes" on page 145). - If the diagnostic programs were completed successfully and you still suspect a problem, see "Solving undetermined problems" on page 177. Important: Clear the BMC system event log and system event/error log after you correct all conditions. This will turn off the system event/error LED if all conditions are corrected. Chapter 5.
