4x10/100/1000Base-T + 4x100/1000Base-X SFP

Managed industrial grade gigabit switch with 4x 10/100/1000Base-T ports and 4x Gigabit/Fast Ethernet SFP ports that provide stable and reliable Ethernet transmission. The switches support a variety of Ethernet functions, including STP/RSTP/MSTP/ ITU-T G.8032 ERPS and multiple μ-Ring for redundant cabling, layer 2 Ethernet IGMP, VLAN, QoS, Security, IPv6, bandwidth control, port mirroring, cable diagnostic and Green Ethernet. Housed in rugged DIN rail or wall mountable enclosures, these switches are designed for harsh environments, such as industrial networking, security automation applications, intelligent transportation systems (ITS) and are also suitable for many military and utility market applications where environmental conditions exceed commercial product specifications. Standard operating temperature range models (-10 to 60°C) and wide operating temperature range models (-40 to 75°C) fulfill the special needs of industrial automation applications.
