Safety First—For You and Your Computer Use the following safety guidelines to help protect your computer system from potential damage and to ensure your own personal safety. When Working Inside Your Computer Before you open the computer cover, perform the following steps in the sequence indicated. NOTICE: Do not attempt to service the computer yourself, except as explained in your online Dell documentation or otherwise provided to you. Always follow installation and service instructions closely.
w w w. d e l l . c o m | s u p p o r t . d e l l . c o m Also, disconnect any telephone or telecommunication lines from the computer. Doing so reduces the potential for personal injury or shock. In addition, take note of these safety guidelines when appropriate: • When you disconnect a cable, pull on its connector or on its strainrelief loop, not on the cable itself.
Protecting Against Electrostatic Discharge Static electricity can harm delicate components inside your computer. To prevent static damage, discharge static electricity from your body before you touch any of your computer’s electronic components, such as the microprocessor. You can do so by touching an unpainted metal surface on the computer chassis. As you continue to work inside the computer, periodically touch an unpainted metal surface to remove any static charge your body may have accumulated.

Microprocessor • Installation guidelines • Upgrading the microprocessor(s) Installation Guidelines • A VRM must be installed for each microprocessor installed. To locate the VRM and microprocessor sockets, see "System Board Components." • For single-processor operations, the processor must be installed in socket 0 and the VRM must be installed in connector 0. Processor socket 1 and VRM connector 1 must be empty. To locate these components, see "System Board Components.
