2 Hardware Upgrades Serviceability Features The computer includes features that make it easy to upgrade and service. No tools are needed for most of the installation procedures described in this chapter. Warnings and Cautions Before performing upgrades be sure to carefully read all of the applicable instructions, cautions, and warnings in this guide.
Removing the Computer Access Panel 1. Remove/disengage any security devices that prohibit opening the computer. 2. Remove all removable media, such as diskettes or compact discs, from the computer. 3. Turn off the computer properly through the operating system, then turn off any external devices. 4. Disconnect the power cord from the power outlet and disconnect any external devices.
Replacing the Computer Access Panel Place the access panel on the chassis with about 1.3 cm (1/2 inch) of the panel hanging off the back of the chassis and slide it into place (1). Ensure that the hole for the thumbscrew is aligned with the hole in the chassis and tighten the thumbscrew (2).
Removing the Front Bezel 1. Remove/disengage any security devices that prohibit opening the computer. 2. Remove all removable media, such as diskettes or compact discs, from the computer. 3. Turn off the computer properly through the operating system, then turn off any external devices. 4. Disconnect the power cord from the power outlet and disconnect any external devices.
Replacing the Front Bezel Position the chassis in the upright position. Insert the two hooks on the top of the bezel into the rectangular holes on the chassis (1) then rotate the bottom of the bezel onto the chassis (2) so that the bottom two hooks on the bezel snap into place.
Installing Additional Memory The computer comes with double data rate 2 synchronous dynamic random access memory (DDR2SDRAM) dual inline memory modules (DIMMs). DIMMs The memory sockets on the system board can be populated with up to four industry-standard DIMMs. These memory sockets are populated with at least one preinstalled DIMM. To achieve the maximum memory support, you can populate the system board with up to 8 GB of memory configured in a highperforming dual channel mode.
Populating DIMM Sockets There are four DIMM sockets on the system board, with two sockets per channel. The sockets are labeled XMM1, XMM2, XMM3, and XMM4. Sockets XMM1 and XMM2 operate in memory channel A. Sockets XMM3 and XMM4 operate in memory channel B.
and the remainder is assigned to single channel. For optimal speed, the channels should be balanced so that the largest amount of memory is spread between the two channels. If one channel will have more memory than the other, the larger amount should be assigned to Channel A. For example, if you are populating the sockets with one 1GB DIMM, and three 512MB DIMMs, Channel A should be populated with the 1GB DIMM and one 512MB DIMM, and Channel B should be populated with the two 512MB DIMMs.
7. Open both latches of the memory module socket (1), and insert the memory module into the socket (2). Figure 2-6 Installing a DIMM NOTE: A memory module can be installed in only one way. Match the notch on the module with the tab on the memory socket. A DIMM must occupy the black XMM1 socket. For maximum performance, populate the sockets so that the memory capacity is spread as equally as possible between Channel A and Channel B. Refer to Populating DIMM Sockets on page 15 for more information. 8.
Removing or Installing an Expansion Card The computer has one standard PCI expansion slot that can accommodate an expansion card up to 17.46 cm (6.875 inches) in length. The computer also has two PCI Express x1 expansion slots and one PCI Express x16 expansion slot.
