58 Installing System Components3 To open the card retention door, press the two release tabs inward. See Figure 3-13.4 If you are installing a new card, remove the filler bracket.NOTE: Keep this bracket in case you need to remove the expansion card. Filler brackets must be installedover empty expansion-card slots to maintain FCC certification of the system. The brackets also keep dust anddirt out of the system and aid in proper cooling and airflow inside the system.5 Prepare the card for installation.See the documentation that came with the card for information on configuring the card, makinginternal connections, or otherwise customizing it for your system.NOTE: Some NICs automatically start the system when they are connected to a network.6 Insert the card into the expansion card connector on the system board (SLOT1, SLOT2, SLOT3,SLOT4, or SLOT5) and press down firmly. Ensure that the card is fully seated in the slot and all cardsand filler brackets are flush with the alignment bar. See Figure 6-2 for the location of the fiveexpansion card connectors.7 Close the card retention door to secure the card(s) in the system.NOTICE: Do not route card cables over or behind the cards. Cables routed over the cards can prevent the systemcover from closing properly or cause damage to the equipment.8 Connect any cables that should be attached to the card.See the documentation for the card for information about the card’s cable connections.9 Close the system. See "Closing the System" on page 41.10 Reconnect the system to the electrical outlet, and turn on the system and attached peripherals.11 Install any device drivers required for the card as described in the documentation for the card.SAS Controller Expansion CardRead the installation instructions in the documentation for your SAS controller card. Install the card inexpansion card connector SLOT2 (see "Installing an Expansion Card" on page 57), and connect thehard-drive activity indicator cable from the card to the AUX_LED connector on the system board (seeFigure 6-2 for the connector location). See "Hard Drives" on page 51 for information about connectinghard drives.MemoryThe four memory module connectors on the system board can accommodate from 512 MB to 4 GB of533-MHz and 667-MHz unbuffered ECC DDR II single or dual-rank memory modules. See Figure 6-2for the location of the four memory module connectors.NOTE: As shown in Figure 6-2, memory slots are not in numeric order on the system board. When installingmemory, take care to install it in the proper slots according to the configuration guidelines in Table 3-2. Installingmemory in the wrong slots will significantly reduce system performance.book.book Page 58 Tuesday, August 25, 2009 1:14 PM
