Economical industrial switch with PoE+ ports and flexible SFP fiber uplinks. PoE+ and SFP ports for flexibility. This switch has eight 10/10/1000-Mbps PoE/PoE+ copper ports and four SFP ports for uplinks. This way you can power distant access points security cameras and other industrial equipment over the copper Ethernet lines at the far edges of your network where it's impractical to run electrical wires. The SFP fiber uplinks give you almost unlimited fiber distance options depending on the SFP. Maximize uptime. Advanced management features help minimize network downtime by enabling you to remotely diagnose and manage network problems. And you'll eliminate the need to send IT technicians on site-thus lowering costs. The switch is fully manageable through SNMP a Web browser Telnet or a console port. Control the bandwidth on each port individually and set up Quality of Service (QoS) priority queuing for critical applications. The switch supports port-based VLAN and IEEE 802.1Q VLAN tagging MAC-based trunking IP-multicast IGMP snooping rapid spanning tree for redundancy. Plus it has 802.1x port-based authentication for security. Fast failovers. The switch gives you maximum network flexibility Spanning Tree Protocol (STP/RSTP) Link Aggregation Control Protocol and a ring protocol. It offers a 20 millisecond or less failover. Extreme applications. Encased in an IP30-rated metal case this switch withstands extreme temperatures from -40degreeC to +75degreeC (-40degree F to +167degree F). Use it for Security and surveillance particularly to backhaul IP security camera data. Military applications especially in ships and other vehicles. Factory automation for controlling machinery PLCs motor drives sensors counters inspection cameras and packaging equipment. Oil and gas fields or remote equipment monitoring and control. Building automation for controlling HVAC and lighting systems. Installation options. The switch features redundant power inputs and includes DIN-rail and panel-mount kits. The power supplies (MDR-40-48 and SDR-240-48) are sold separately. The switch also includes a serial cable (RJ-45/DB9) for the console connection.This product is covered by one of more of the following United States Patent Nos. 7457250 8902760 and/or 9019838.
