do the following to install an adapter:

    when you handle esd-sensitive devices, take precautions to avoid damage from static electricity. for details on handling these devices, see "handling staticsensitive devices" on page 31.

    1.review the information in "safety information" on page vii.

    2.turn off the computer and attached devices.

    3.disconnect all external cables and power cords; then, remove the side cover. see "removing the side cover" on page 32.

    4.determine which pci slot you will use for the adapter.

    check the instructions that come with the adapter for any requirements,restrictions,or cabling instructions. it might be easier to route any cables before you install the adapter.

    5.for full-length adapters, rotate the rear adapter support bracket to the open(unlocked) position and remove it from the computer. rotate the front adapter support bracket to the open position. if you are installing a smaller adapter,remove only the rear support bracket.

    6.remove the expansion-slot cover. from the rear of the computer, press on the slot cover. grasp it and pull it out of the expansion slot. store it in a safe place for future use.

    expansion-slot covers must be installed on all vacant slots. this maintains the electromagnetic emissions standards of the computer and ensures proper ventilation of computer components.

    7.set any jumpers or switches on the adapter or system board as described by the adapter manufacturer.

    8.when you are ready, remove the adapter from the static-protective package. it is best to move the adapter directly from the static-protective package to the adapter slot. if this is not possible, set the adapter down on its static-protective package on a hard surface. avoid touching the components and gold-edge connectors on the adapter.

    9.to install the adapter, carefully grasp the adapter by the top edge or upper corners, and align it with the expansion slot guides; then press the adapterfirmlyinto the expansion slot.

    be certain that the adapter is correctly seated in the expansion slot beforeyou turn on the computer. incomplete installation of an adapter might damage the system board or the adapter.

    10.connect required cables to the adapter. route cables so that they do not block the flow of air from the fans.

    11.if you have another adapter, repeat steps 1 - 10. if you have another option to install, go to that section heading. otherwise, complete the rest of the steps in this section.

    12.if you have installed a full-length adapter, rotate the front adapter support bracket to the closed (locked) position.

    13.reinstall the rear adapter support bracket; then rotate the bracket to the closed(locked) position.

    the rear retaining bracket sits against the computer cover. you might find it easier to lay the computer on its side to replace the cover.

    14.replace the support bracket.

    15.replace the side cover, see "replacing the cover" on page 44 for details.

    16.reconnect the external cables and power cords; then turn on the attached devices and the computer.
