Installing the Air Duct

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: The air duct configuration differs with the number of processors installed on the system board. For two-processor configuration, only the air duct 3 is installed between the processors 1 and 2; for four-processor configuration, the air ducts 1, 2 and 3 should all be installed. The Figure 3-7shows the four-processor configuration.
