Do not touch the bottom of the processor. Touch only the side edges of the processor. Installing A Processor 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: If you are installing a single processor, it must be installed in socket CPU1. NOTE: If you install a second processor, you must remove the dummy fan from the FAN 6 slot, install a cooling fan in the FAN 6 slot, and upgrade both the riser cards (riser1 and riser 2). For more information, see Expansion Card Installation Guidelines. NOTE: When installing a second processor in your system with a 350 W redundant power supply, it is highly recommended that you upgrade to 550 W redundant power supply, to avoid potential degraded performance. 76
