Important Requirements

To achieve the best audio quality for your IP paging system, we recommend building a dedicated VLAN for this system with network equipment compatible with multicast protocol. Netbell IP paging devices support PoE/PoE+, and a properly configured network infrastructure will ensure a smooth installation.

• The speakers and the PC running the NACT desktop app must be on the same LAN
• Network and Switch Requirements:
  • Power over Ethernet (PoE/PoE+) Switch Ports
  • Minimum CAT5 cable with maximum of 100 meters from the device to switch
  • Network switch capacity to handle power loads for all devices
  • Router: Must support IGMP (Internet Group Management Protocol) and PIM (Protocol Independent Multicast)
  • Switch: Must support IGMP snooping
