Chapter 6. Symptom-to-FRU index This index supports the BladeCenter T Type 8720 and 8730 systems. Eserver Notes: 1. Check the configuration before you replace a FRU. Configuration problems can cause false errors and symptoms. 2. For IBM devices not supported by this index, refer to the manual for that device. 3. A removed hot-swap module or drive must be replaced within one minute of removal. 4. A removed hot-swap blade must be replaced within 20 minutes of removal. The symptom-to-FRU index lists symptoms, errors, and the possible causes. The most likely cause is listed first. Use this symptom-to-FRU index to help you decide which FRUs to have available when servicing the system. The left-hand column of the tables in this index lists error codes or messages, and the right-hand column lists one or more suggested actions or FRUs to replace. Note: In tables with more than two columns, multiple columns are required to describe the error symptoms. Take the action or replace the FRU suggested first in the list of the right-hand column, then try the server again to see if the problem has been corrected before taking further action. Note: Try reseating a suspected component or reconnecting a cable before replacing the component. Error symptoms You can use the following information to find solutions to problems that have definite symptoms. Attention: If diagnostic error messages appear that are not listed in the following tables, make sure that your BladeCenter T unit has the latest level of firmware code installed. If you have just added a new option and your system is not working, complete the following procedure before using the troubleshooting charts: 1. Remove the option that you just added. 2. Run the diagnostic tests to determine if your system is running correctly. 3. Reinstall the new device. © Copyright IBM Corp. 2004 89
