Removing and installing a PCI card

Important: Only PCI add-in cards in PCI slots 1 and 2 are hot-pluggable. If you are installing or removing a PCI card from PCI slot 3 through 7, see page 82 for more information.

Caution: Expansion slot covers must be installed over all vacant slots to maintain the electromagnetic emission characteristics of the server and to ensure proper system cooling.

Determining PCI slot status

The PCI slots 1 and 2 have a LED indicator to display the PCI hot-plug status. For more information on how to determine the slot status, refer to “Hot-plug PCI Express slot LED indicators” section on page 25.

1Perform the pre-installation instructions described on page 39.

2If you are using a Microsoft Windows operating system, double- click the Unplug/Eject icon in the taskbar to open the Unplug or Eject Hardware menu.

3Select the device to be removed and click Stop.

4Make sure that the power LED on the rear of the PCI slot is turned off before disconnecting any cables attached to the card.
