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 the Warranty and Support Guide before installing and connecting your system to the electrical power system. Opening and Closing the PC • Write down and save the system model and serial numbers, all installed options, and other information about the system.
After Closing the PC Replacing the Side Panel To avoid injury and equipment damage, always follow this procedure in this order after closing the PC. 1 Place the side panel in the proper position on the chassis and slide it into place. 1 Reconnect the power cord. WARNING: To reduce the risk of electrical shock, fire, or damage to the equipment, do not plug telecommunications or telephone connectors into the network interface card (NIC) (labeled as an Ethernet connector).
Replacing the Front Panel 1 Align the top of the front panel with the top of the chassis front. 2 Press the panel onto the chassis at the top and at each side near the bottom until the panel snaps into place. Removing and Replacing Drives Your PC has several drives that you can replace or upgrade. See the preceding topic, “Locating Components Inside the PC,“ for drive type and location.
Removing a Drive 1 Complete the procedures to prepare the PC, to remove the side panel, and to remove the front panel. See “Opening and Closing the PC“ on page 1. 2 Locate the drive you want to remove. 3 Release the drive from the chassis by lifting the tab (1) on the latch drive bracket, and then sliding (2) the drive partway out of the bay. (The latch drive bracket secures the drives in their respective positions in the chassis.
6 5 Disconnecting the Serial ATA Hard Disk Drive Cables 3 Make sure the jumper on the new optical drive or new Parallel ATA hard disk drive is in the CS (Cable Select) position. Your drive may vary from the illustration. The Serial ATA hard disk drive does not use Cable Select. CS SL MA Disconnecting the Parallel ATA Hard Disk Drive Cables 5 Pull the drive out of the drive bay. 6 If you are replacing the old drive with a new drive, remove the four guide screws (two on each side) from the old drive.
For a second hard disk drive, slide the drive into the bay (with connectors facing out) and align the screw holes (3). Insert the two screws (4). Connecting the Memory Card Reader Drive Cable Connecting the Diskette (Floppy) Drive Cables 6 Reconnect the power and data cables to your drive as indicated in the following illustrations. If it is present, reconnect the sound cable.
Adding Memory Your PC comes with random access memory (RAM), which temporarily stores data and instructions on your PC. The PC ships with one or more memory modules, but you can replace the existing memory module(s) with higher-capacity ones. The motherboard contains sockets for DDR DIMMs (double data rate dual in-line memory modules). The exact number of sockets and type of DDR memory module depends on which model PC you have.
5 Push down the two retaining clips on the ends of the memory socket until the memory module pops out of the socket. WARNING: Do not pull the memory module out of the socket. Use the retaining clips to eject the module. 6 Lift the memory module from the memory socket. 2 The memory module can be installed in only one way. Match the notch on the module with the tab on the memory socket (B). Push the module carefully and firmly into the slot, ensuring that the latches on both ends snap into place.
Removing an Add-In Card 1 Complete the procedures to prepare the PC and to remove the side panel. See “Opening and Closing the PC“ on page 1. 2 Gently lay the PC on its side. 3 On the back of the PC, remove the screw from the bracket cover for the add-in card slots, and then remove the bracket cover. 6 If you are not replacing the old add-in card with a new add-in card, close the open slot by inserting the metal slot cover into the opened slot.
Replacing the Battery A lithium battery on the motherboard provides backup power for the PC’s timekeeping capability. The battery has an estimated life expectancy of seven years. When the battery starts to weaken, the date and time may be incorrect. If the battery fails, replace it with a CR2032 lithium battery (3 volt, 220mAH rating) or an equivalent battery. WARNING: There is danger of explosion if the battery is incorrectly replaced. Replace only with the same, or equivalent, type of battery.
