Antaira LMP-1204G-SFP-bt 12-Port Industrial PoE++ 90W Managed Ethernet Switch

Antaira Technologies’ LMP-1204G-SFP-bt is a 12-port industrial Gigabit PoE++ managed Ethernet switch embedded with 4*10/100/1000Tx Ethernet ports that support IEEE 802.3bt for a maximum of 90W/port, 4*10/100/1000Tx Ethernet ports with IEEE 802.3af/at support for a maximum of 30W/Port, and 4*100/1000 dual rate SFP slots for fiber connection. The LMP-1204G-SFP-bt is a fully-manageable Light Layer 3 Ethernet switch that is pre-loaded with a user-friendly web management console design. It supports the ring network redundancy function using the market’s open standard ITU-T G.8032 Ethernet Ring Protection Switch (ERPS) protocol that has a <50ms network recovery time. The advanced network filtering and security functions, such as IGMP, VLAN, QoS, SNMP, RMON, Modbus TCP, and 802.1X/HTTPS/SSH/SSL increase determinism and improve network management for remote SCADA systems or control networks. The LMP-1204G-SFP-bt is IP30 rated and DIN-rail mountable. There are also a standard temperature range (STD: -10°C to 65°C). It also provides high EFT and ESD protection for industrial networking applications, such as power/utility, water wastewater, oil/gas/mining, factory automation, security surveillance, ITS and any other outdoor or harsh environment.
