4x10/100/1000Base-T + 2x100/1000Base-X SFP with 4xPoE+

4-Port Managed GbE PoE Switch

The IGS-402SM-4PH24 series models are managed industrial grade Gigabit PoE (Power over Ethernet) switches with 4 ports 10/100/1000Base-T PoE ports and 2 ports Fast/Gigabit Ethernet SFP ports that provide stable and reliable Ethernet transmission. With dual power input design, the series models can provide redundancy mechanism for critical applications that need always-on connections. These switches can also operate either at standard operating temperature range (-10 to 60°C) or at wide operating temperature range (-40 to 75°C) so as to fulfill the special needs of industrial automation applications. Housed in rugged DIN rail or wall mountable IP-30 enclosures, these switches are perfect choices for harsh environments, such as industrial networking, intelligent transportation systems (ITS) and are also suitable for many military and utility market applications where environmental conditions exceed commercial product specifications. Apart from specially-designed outlook and hardware features, the Ethernet switches also support a wide variety of management functions, including STP/RSTP/MSTP/ ITU-T G.8032 Ring and multiple u-Ring for redundant cabling, advanced PoE management functions such as PoE device auto-checking and auto reset, PoE power on/off weekly scheduling, layer 2 Ethernet IGMP, VLAN, QoS, Security, IPv6, bandwidth control, port mirroring, cable diagnostics and Green Ethernet.
