Cabling Your Public and Private Networks
The network adapters in the cluster nodes provide at least two network connections for each node. These connections are
described in Table 3-2 .
Table 3-2. Network Connections

Description
Public
network
All connections to the client LAN.
At least one public network must be configured for Mixed mode for private network failover.
Private
network
A dedicated connection for sharing cluster health and status information between the cluster nodes.
For point-to-point Fast Ethernet, connect a crossover Ethernet cable between the Fast Ethernet network
adapters in both cluster nodes.
For point-to-point Gigabit Ethernet, connect a standard Ethernet cable between the Gigabit Ethernet network
adapters in both cluster nodes.
NOTE: Network adapters connected to the LAN can also provide redundancy at the communications level in
case the cluster interconnect fails. See your MSCS documentation for more information on private network
redundancy.
Figure 3-11 shows an example of network adapter cabling in which dedicated network adapters in each node are connected to
the public network and the remaining network adapters are connected to each other (for the private network).

Cabling Your Public Network
The public network connection (client network) to the cluster nodes is provided by a network adapter that is installed in each
node. Any network adapter supported by the system running TCP/IP may be used to connect to the public network segments.
Additional network adapters may be installed to support additional separate public network segments or to provide
redundancy for the public network.
NOTE: Ensure that the network adapters in both cluster nodes are identical.
