Use one or more Category 5/6 Ethernet cables to connect the Trinzic 1410 or Trinzic 1420 appliance to the network.

1. Connect an Ethernet cable from the LAN1 port on the appliance to your network switch or router.
2. If you want to connect your appliance for HA (high availability), connect the LAN1 and HA ports on both appliances to a switch or router on your network. The VIP (Virtual IP), LAN1, and HA port addresses must be on the same subnet and must be unique for that subnet.

Figure 14 Cabling a Single Appliance and an HA Pair to a Network

Note: By default, an Infoblox appliance automatically negotiates the optimal connection speed and transmission type (full or half duplex) on the physical links between its LAN1, LAN2, HA, and MGMT ports and the Ethernet ports on a connecting switch. If the two appliances fail to auto-negotiate the optimal settings, see the Infoblox NIOS Administrator Guide for steps you can take to resolve the problem.

3. (Trinzic1400 appliances only) To ensure that VRRP (Virtual Router Redundancy Protocol) works properly, configure the following settings at the port level for all the connecting switch ports (HA, LAN1, and LAN2):

1. • Spanning Tree Protocol: Disable. For vendor specific information, search for "HA" in the Infoblox Knowledge Base system at https://support.infoblox.com/
   • Trunking: Disable
   • EtherChannel: Disable
   • IGMP Snooping: Disable
   • Port Channeling: Disable
   • Speed and Duplex settings: Match these settings on both the Infoblox appliance and switch
   • Disable other dynamic and proprietary protocols that might interrupt the forwarding of packets

4. Use the Infoblox GUI to access the Infoblox appliance from a management system. Through the GUI, you can set up and administer the appliance. For management system requirements and access instructions, see Accessing the Appliance.
