Use one or more Category 5/6 Ethernet cables to connect the Infoblox 4000 Series appliance to the network.

1. Connect an Ethernet cable from the LAN1 port on the Infoblox 4000 Series to the network switch or router, as indicated in Figure 12.
2. (Supported with IB-4010 and PT-4000 appliances) To connect the Infoblox 4000 Series 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.

Appliance–Network Connectivity

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 or load balancer.
Occasionally, the appliances may fail to auto-negotiate that speed and type, and instead connect at lower speeds of either 100 or 10 Mbps using potentially mismatched full- and half-duplex transmissions. If this occurs, begin by determining whether there is a firmware upgrade available for the switch. If so, apply the firmware upgrade to the switch and test the connection. If that does not resolve the issue, manually set the ports on the Infoblox appliance and on the switch to make 1000-Mbps full-duplex connections. See the section Modifying Ethernet Port Settings in the Infoblox NIOS Administrator Guide for the steps to resolve the problem.
(Applies to Infoblox IB-4010 and PT-4000/PT-4000-10GE) To ensure that VRRP (Virtual Router Redundancy Protocol) works properly, configure the following settings at the port level for all the connecting switch ports (LAN1, LAN2 and HA where applicable):

• 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.

Use the Grid Manager from a management system to access, set up and administer the Infoblox appliance. For management system requirements and access instructions, see Accessing the Infoblox 4000 Series Appliance.

SFP/SFP+ Installation and Removal Guidelines

After receiving a shipped Infoblox 4000 Series appliance with SFP or SFP+ support, install the transceivers into your appliance before turning power on to the system for the first time.
Should circumstances require you to ship an appliance to Infoblox for repair or replacement, remove all SFP or SFP+ transceivers from your appliance before shipping it back to Infoblox. Keep your transceivers in your facility until the appliance is replaced or repaired and subsequently returned to you.
