Expansion Cards 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. Item Description PCI Express x1 expansion slot...
Page 82 On the rear of the computer, a slot cover lock secures the expansion card brackets and expansion slot covers in place. Lift up on the tab at the top of the lock and rotate the lock open. Before installing an expansion card, remove the expansion slot cover or the existing expansion card.
Page 83 If you are removing a standard PCI card, hold the card at each end, and carefully rock it back and forth until the connectors pull free from the socket. Pull the expansion card straight up from the socket (1) then away from the inside of the chassis (2) to release it from the chassis frame.
Page 84 CAUTION: After removing an expansion card, you must replace it with a new card or expansion slot cover for proper cooling of internal components during operation. To install a new expansion card, hold the card just above the expansion socket on the system board then move the card toward the rear of the chassis (1) so that the bracket on the card is aligned with the open slot on the rear of the chassis.

Page 129: Installing Additional Memory
Installing Additional Memory The computer comes with double data rate 2 synchronous dynamic random access memory (DDR2- SDRAM) 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.
Page 130: Populating Dimm Sockets
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. Item Description Socket Color...
Page 131: Installing Dimms
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.
Page 132 Open both latches of the memory module socket (1), and insert the memory module into the socket (2). 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.
Page 133: Expansion Cards
Expansion Cards The computer has one standard low-profile 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. NOTE: The PCI and PCI Express slots support only low profile cards.
Page 134 Release the slot cover retention latch that secures the PCI slot covers by lifting the green tab on the latch and rotating the latch to the open position. Before installing an expansion card, remove the expansion slot cover or the existing expansion card.
Page 135 If you are removing a standard PCI card, hold the card at each end, and carefully rock it back and forth until the connectors pull free from the socket. Pull the expansion card straight up from the socket (1) then away from the inside of the chassis (2) to release it from the chassis frame.
Page 136 CAUTION: After removing an expansion card, you must replace it with a new card or expansion slot cover for proper cooling of internal components during operation. To install a new expansion card, hold the card just above the expansion socket on the system board then move the card toward the rear of the chassis (1) so that the bracket on the card is aligned with the open slot on the rear of the chassis.
Page 137: Cable Management
