Use one or more optical fiber Ethernet cables to connect the appliance to the network, depending on the deployment.

1. Connect an Ethernet cable from the LAN1 port on the to the network switch or router, as indicated in *<span style="color: #0000ff">[Figure 11](#CablingtheAppliancetotheNetwork-bookmark43)</span>*.
2. (*Supported with* *Infoblox-4030* *and* *Infoblox-4030-10GE appliances in* *HA mode*) To connect the Infoblox appliance appliance for HA (high availability), connect the HA ports on both appliances to a switch on your network. The VIP (Virtual IP), LAN1, and HA port addresses must be on the same subnet and be unique for that subnet.

**Note**: By default, the appliance automatically negotiates an optimal connection speed and transmission type (full or half duplex) on physical links between its LAN1, LAN2, HA, and MGMT ports and the Ethernet ports on the connecting switch or load balancer. If the appliance fails to auto-negotiate the optimal settings, refer to the *Infoblox* *NIOS* *Administrator* *Guide* for steps to resolve the problem.
