206 Planning, Installing, and Managing the IBM System x3950 M2Figure 4-7 x3950 M2: installation of the ScaleXpander key7. Close the media hood assembly and tighten the captive screws.The x3850 M2 is now enabled for scalability. To indicate that the server is now anx3950 M2, you might want to replace the front bezel of the x3850 M2 with theone provided in the ScaleXpander Option Kit. Follow the replacementinstructions included in the ScaleXpander Option Kit.4.5.2 Configuring for a LAN connectionAt least one system in a complex must have a valid LAN connection to theRemote Supervisor Adapter (RSA) II. The RSA II has a 10/100 Mbps networkinterface..To configure the LAN interface:1. Plug in the power cables and power on your system.2. When prompted, press F1 to enter the System Setup in BIOS.3. Select Advanced Setup → RSA II Settings → RSA LAN interface.Note: The new bezel does not have a sticker where you can enter the originalserial number of your server. You should record this data separately.Note: We recommend configuring the RSA II in each node with uniquenetwork settings, not just at the primary node. Configuring each RSA II with anIP address means you can more easily manage the complex from any node.
