Owner manual

If you install expansion cards, you may have some difficulty in directly determining the bus number of a controller on a particular expansion card. However, the
PCI bus scan order listed in Table6-1 can help you determine the relative numbering of PCI buses within the expansion slots. For example, a PCI controller
residing in expansion slot 3 will never have a lower bus number than one in slot 2 because slot 2 precedes slot 3 in the scan order.

Installing an Expansion Card
1. Remove the back cover (see "Removing the Back Cover" in "Troubleshooting Your System").
See the documentation that came with the expansion card for information on configuring the card, making internal connections, or otherwise customizing
the card for your system.
2. Open the plastic expansion-card latch:
a. Press and hold the plastic tab on the outside of the system chassis.
b. Press the release tab on the latch inside the system chassis (see Figure6-5).
c. Open the expansion-card latch and remove the filler bracket.
3. If your operating system does not support hot-plug expansion cards, turn off the system, including any attached peripherals, and disconnect the
system from its electrical outlet.
If your operating system does support hot-plug expansion cards, press the expansion-slot notify button and wait until the status indicator turns green.
See "Expansion-Slot Indicator Codes" in "Indicators, Messages, and Codes" for information on expansion-slot status.
4. Install the expansion card (see Figure6-5).
a. Position the expansion card so that the card-edge connector aligns with the expansion-card connector on the I/O board.
b. Insert the card-edge connector firmly into the expansion-card connector until the card is fully seated.

CAUTION: If your system's operating system does not support hot-plug PCI or PCI-X expansion cards or the expansion card itself does not
support hot-plug installation, turn off the system, including any attached peripherals, and disconnect the system from its electrical outlet. For
more information, see "Safety First—For You and Your System" in "Troubleshooting Your System."
NOTICE: See "Protecting Against Electrostatic Discharge" in the safety instructions in your System Information document.
