To install the dual-port network adapter, complete the following steps:

Read the safety information that begins on Safety and Installation guidelines.
Turn off the server and peripheral devices and disconnect the power cords and all external cables, if necessary.
Remove the cover (see Removing the cover).
Remove the PCI riser-card assembly (if installed) from PCI riser connector 2 (see Removing a PCI riser-card assembly).
Remove the adapter filler panel on the rear of the chassis (if it has not been removed already).
Figure 1. Adapter filler panel removal
Touch the static-protective package that contains the new adapter to any unpainted metal surface on the server. Then, remove the adapter from the package.
Align the adapter so that the port connectors on the adapter line up with the pin and thumbscrew on the chassis; then, align the connector of the adapter with the adapter connector on the system board.
Figure 2. Network adapter installation
Press the adapter firmly until the pin, and retention brackets engage the adapter. Make sure the adapter is securely seated on the connector on the system board.
Attention: Make sure the port connectors on the adapter are aligned properly with the chassis on the rear of the server. An incorrectly seated adapter might cause damage to the system board or the adapter.
Fasten the thumbscrew on the rear side of the chassis.
Figure 3. Screws engagement
Fasten the two captive screws on the network adapter.
Reinstall the PCI riser-card assembly in PCI riser connector 2 if you have removed it previously (see Replacing a PCI riser-card assembly).
