Safety Information This product has not been evaluated for connection to an "IT" power system (an AC distribution system with no direct connection to earth, according to IEC 60950). WARNING: Please read "Safety Information" in your Warranty and Support Guide before installing and connecting your system to the electrical power system. The Upgrading and Servicing Guide provides instructions on how to remove and replace hardware components of your PC. To open the lid of your PC, gently push down on the lid before sliding it back. Opening and Closing the PC Preparing the PC Before you upgrade any component in your PC, you need to prepare the PC so that you can safely handle it and the components. Read the following items before attempting to upgrade or service the PC: • These procedures assume familiarity with the general terminology associated with personal computers and with the safety practices and regulatory compliance required for using and modifying electronic equipment. • Write down and save the system model and serial numbers, all installed options, and other information about the system. It's easier to consult this information than to open up and examine the PC. • It is recommended that you use an antistatic wrist strap and a conductive foam pad when working on the system. WARNING: Always disconnect the modem cord from the telephone system, and then disconnect the PC from the power source before removing the front and side panels of the PC. Failure to do so before you open the PC or do any procedures can result in personal injury or equipment damage. Upgrading and Servicing Guide 1
