PoE Managed Gigabit Ethernet Switch

The IGS-803SM-8PH24 Series are Gigabit Ethernet managed PoE+ Ethernet switches that come standard with 8 ports 10/100/1000Base-T(X), its port 1 to port 8 compliant with IEEE802.3af/at (PoE), and 3 SFP Gigabit/Fast Ethernet ports. The IGS-803SM-8PH24 series Ethernet switches provide up to 30W watts of power per PoE port for industrial heavy-duty PoE devices, such as weather-proof IP cameras, high-performance wireless access points, and rugged IP phones. The IGS-803SM-8PH24 Ethernet switches are highly versatile, support 24/48VDC power input booster, and it is able to fit all the common 24/48 VDC power system found in industrial fields or cabinets. The Ethernet switches support a variety of management functions, including STP/RSTP/MSTP and ITU-T G.8032 Ring <50ms recovery time, Advanced PoE management, PoE device auto-checking and auto reset, PoE power Weekly scheduling, IGMP, VLAN, QoS, Security, IPV6, bandwidth Control, port mirroring, cable diagnostic, and Green Ethernet. The IGS-803SM-8PH24 series is designed especially for security automation applications with high EMS immunity to ensure uninterrupted reliability of PoE systems such as IP surveillance, passenger information systems, auto gate entry system which can benefit from a scalable backbone construction and Power-over-Ethernet support.
