These link ports often have higher bandwidth than the switchports, however, care must be taken not to exceed the total AV bandwidth between switches.IP-Logic Isolated VLANAll IP-Logic devices should reside on a single VLAN. Most switches default to a single VLAN andthere is no need to create more.It is highly recommended to isolate the IP-Logic VLAN environment from all other networkeddevices in a facility (for example: control systems, wireless routers, computers, printers, etc.).The Essentials control server is equipped with two network ports: AVoIP LAN and Control LAN.The AVoIP LAN is used to connect Essentials to other IP Logic devices such as ZIG-IPPRO-RX andZIG-IPPRO-TX. The Essentials Control LAN is connected to the facility Ethernet to interface with3rd party Control Systems. If the Control LAN is provided with Internet access, then Essentials canSwitch CascadingTransmitter EssentialsReceiverReceiverHDMIAVoIP EthernetSystem Deployment Guidelines
