Before removing the components, be sure to determine the minimum configuration for each component and
follow all guidelines in the server user guide.
Always use the recommended minimum configuration above before removing any processors. If you are
unable to isolate the issue with the configuration above, you will then remove all but one of the processors.
CAUTION: Before removing or replacing any processors, be sure to follow the guidelines
provided in "Performing processor procedures in the troubleshooting process (on page 67 )."
Failure to follow the recommended guidelines can cause damage to the system board, requiring
replacement of the system board.

Server health LEDs
Some servers have an internal health LED and an external health LED, while other servers have a single
system health LED. The system health LED provides the same functionality as the two separate internal and
external health LEDs. Depending on the model, the internal health LED and external health LED may either
appear solid or they may flash. Both conditions represent the same symptom.
