This product has not been evaluated for connection to an "IT" power system (an AC distribution system with no direct connection to the earth, according to IEC 60950). WARNING: Before you install and connect your system to the electrical power system, please read "Safety Information" in the Limited Warranty and Support Guide. This Upgrading and Servicing Guide provides instructions for removing and replacing the hardware components of your computer. Opening and Closing the Computer Upgrading and Servicing Guide 1 Preparing the computer Before you upgrade any component in your computer, you must prepare it so that you can safely handle it and the components. Read the following items before attempting to upgrade or service the computer: 1 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. 2 Write down and save the system model and serial numbers, all installed options, and other information about the system. It is easier to consult this information than to open and examine the computer. [. . . ] See "Opening and Closing the Computer" on page 1. 14 Upgrading and Servicing Guide Removing the memory card reader 1 Prepare the computer to be opened, and then remove the side and front panels. See "Opening and Closing the Computer" on page 1. 2 Release the drive by removing the screw on the top of the memory card reader, sliding the memory card reader to the left to loosen it, and then pulling it partway out of the front of the chassis. 3 Disconnect the cables from the back of the memory card reader. 4 Pull the memory card reader out of the front of the chassis. Upgrading and Servicing Guide 15 Adding or replacing the memory card reader 1 Complete the procedures to remove the memory card reader, if necessary. See "Removing the memory card reader" on page 15. 2 Slide the memory card reader partway into the front of the chassis. 3 Attach the cables to the back of the memory card reader. 4 Push the memory card reader into the chassis until the screw hole on the chassis is aligned with the screw hole on the top of the memory card reader, and then insert the short screw to secure the memory card reader to the chassis. 5 Replace the front and side panels, and close the computer. See "Opening and Closing the Computer" on page 1. 16 Upgrading and Servicing Guide Removing the hard disk drive 1 Prepare the computer to be opened, and then remove the side and front panels. See "Opening and Closing the Computer" on page 1. 3 Remove the two screws that secure the hard disk drive cage to the chassis. 4 Use a screwdriver to push down the latch on the side of the hard disk drive cage, and then slide the hard disk drive cage away from the bottom of the chassis. Upgrading and Servicing Guide 17 5 Lift the hard disk drive cage out of the chassis, and then remove the hard disk drive cables. For most drive cables, use a gentle rocking motion to remove the plug. For Serial ATA hard disk drive cables, press the latch (A) (select models only) in the center of each plug (B), and then pull the plug out of the drive connector. B A MA ST ER SLA VE To C PU 6 Remove the four screws that secure the hard disk drive to the hard disk drive cage, and then slide the hard disk drive out of the hard disk drive cage. 18 Upgrading and Servicing Guide Adding or replacing a hard disk drive 1 If you are replacing an existing hard disk drive, remove it. See "Removing the hard disk drive" on page 17. 2 Slide the new hard disk drive into the hard disk drive cage, making sure that the hard disk drive cables are facing the top of the drive cage. NOTE: The hard disk drive cage may have slots for two (2) or three (3) hard disk drives. If you are replacing more than one drive or adding drives, place the primary drive in the lowest slot of the cage. 3 Align the hard disk drive with the four screw holes on the hard disk drive cage, and then install the four screws that secure the drive to the cage. NOTE: If you are replacing an old drive with a new drive, remove the four guide screws from the old drive and use them to install the new drive. If you are installing additional hard disk drives, use four standard 6-32 screws that you purchase separately. Upgrading and Servicing Guide 19 4 Align the four guides on the bottom of the hard disk drive cage with the four holes on the back of the chassis, and then slide the cage down toward the bottom of the chassis until it locks into place. 5 Attach the hard disk drive cables. A A -- Connect to a primary hard disk drive. MA ST ER B C SLA VE B -- Connect to a secondary hard disk drive (select models only). C -- Connect to the computer motherboard.

See "Opening and Closing the Computer" on page 1. Upgrading and Servicing Guide 21 Adding Memory Your computer comes with random access memory (RAM), which temporarily stores data and instructions on your computer. The computer is shipped with one or more memory modules installed, but you can replace the existing memory module(s) with higher-capacity modules. The motherboard contains sockets for DDR DIMMs (double data rate dual in-line memory modules). [. . . ] See "Opening and Closing the Computer" on page 1. 3 Remove any cabling, if necessary, so that you can reach the battery. 4 Remove any memory modules, if necessary, so that you can reach the battery. See "Adding Memory" on page 22. [. . . ]
