IBM Type 8720 Server User Manual


 
Chapter 6. Symptom-to-FRU index
This index supports the Eserver BladeCenter T Type 8720 and 8730 systems.
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.
