IPN-8U Network switching module

Network switching module IPN-8U is designed for use in decentralized Intercom and PA/ GA system. IPN-8U is a compact switching unit for 8 subscribers with Uk0-interface and 4 FastEthernet ports for connection to IP-network. All Uk0-interfaces are equipped with Powerover-U function – “phantom” power supply of subscribers with automatic protection against over-load. Ports of the built-in FastEthernet switch support PoE according to IEEE 802.3af Class 0, and can be used to connect and feed IP-subscriber devices.
