Antaira’s LNP-0500 series switch is a smart 5-port Industrial Unmanaged Ethernet Switch supporting IEEE-802.3at compliance (Power-over-Ethernet Plus) on ports 1 to 4. The switch is classified as power sourcing equipment (PSE), and when used in this way, the LNP-0500 series switch enables centralization of the power supply and provides up to 30 watts of power per port. The LNP-0500 can be used to power IEEE 802.3af or 802.3at compliant power devices (PD), eliminating the need for additional wiring, and support IEEE 802.3/802.3u/802.3x with 10/100BTx, full or half duplex, MDI/MDI-X auto sensing to provide an economical solution for the Industrial Ethernet Network. In addition, the Network Broadcast Storm Protection and built-in relay warning function alerts network engineers when power failures or port breaks occur.Network broadcast storm protection 4-Port IEEE 802.3at compliant PoE+ Function with 30W/Port 1-Port 10/100Tx Fast Ethernet Supports Auto MDI/MDI-X Function Store-and-Forward Switching Architecture 2K MAC Address Table EFT Protection: 2,000 VDC support ESD Protection: 6,000 VDC support Redundant Power Input Design – 48~55VDC Built-in 1 relay output for Port Break Alarm IP30 Rugged Aluminum Case Design DIN-Rail and Wall Mount support
