Managed ethernet switch LMP-2804G-4XS-24

28 portslayer 3gigabit Ethernet

Product Overview Antaira Technologies’ LMP-2804G-4XS-24 is a 28-port industrial gigabit PoE+ managed Ethernet switch featuring 24*10/100/1000T Gigabit Ethernet with IEEE 802.3at compliant PoE (30W/port) and 4*1G/2.5G/10G SFP+ Slots. Ideal for applications requiring high port density, wide bandwidth, and long-distance communication. This fully manageable Light Layer 3 Ethernet switch comes with a user-friendly web management console. It supports ring network redundancy via ITU-T G.8032 ERPS protocol (<50ms network recovery). Advanced network filtering and security functions include IGMP, VLAN, QoS, SNMP, port lock, RMON, Modbus TCP, and 802.1X/HTTPS/SSH/SSL, enhancing determinism and network management for remote SCADA/control networks. Designed with an IP30 rated 1U 19” rackmount, it supports dual power input (12~55VDC) and a built-in voltage booster, providing full 48VDC PoE power for any PoE application. The standard operating temperature model (-10° to 65˚C) makes it suitable for harsh environments such as power/utility, transportation, water/wastewater treatment, oil/gas, and security surveillance.
