Inside The System
CAUTION: Many repairs may only be done by a certified service technician. You should only perform
troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or
telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your
warranty. Read and follow the safety instructions that came with the product.
NOTE: Components that are hot-swappable are marked orange and touch-points on the components are marked
blue.
NOTE: Your system supports two or four processor configurations. A cooling shroud is present only in a two-
processor system. In a four-processor system, the cooling shroud is replaced by a processor expansion module
(PEM).
