# Insert the Adapter in the Computer

| NOTE: If you are replacing an existing adapter with a new adapter, you must re-install the driver.

## Insert a PCI Express Adapter in the Server

1. Turn off the server and unplug the power cord, then remove the server's cover.

| CAUTION: Turn off and unplug the server before removing the server's cover. Failure to do so could endanger you and may damage the adapter or server.

2. Remove the cover bracket from a PCI Express slot (v1.0a or later).
   PCI-Express slots and adapters vary in the number of connectors present, depending on the data lanes being supported.

| NOTE: The Intel® 10 Gigabit AT Server Adapter will only fit into x8 or larger PCI Express slots. Some systems have physical x8 PCI Express slots that actually support lower speeds. Please check your system manual to identify the slot.

3. Insert the adapter in an available, compatible PCI Express slot. Push the adapter into the slot until the adapter is firmly seated. You can install a smaller PCI Express adapter in a larger PCI Express slot.

| CAUTION: Some PCI-Express adapters may have a short connector, making them more fragile than PCI adapters. Excessive force could break the connector. Use caution when pressing the board in the slot.

4. Repeat steps 2 through 3 for each adapter you want to install.
5. Replace the server cover and plug in the power cord.
6. Turn the power on.
