Note: In all configurations with a server blade as the control node, NIC2 of the server blades installed in the same enclosure as the control node will also be connected to the switch used to provide external connectivity. Cluster management software or the system administrator for the cluster must determine what steps are necessary to provide appropriate connectivity to the external network. In a typical installation, NIC2 of the server blades installed in the c3000 enclosure with the control node will be turned off. Contact an HP representative for additional information.
