| The EX74000 hardened managed PoE Ethernet switch series functions at temperatures ranging from -40°C to 75°C (-40°F to 167°F).The EX74000 supports SFP DDM (Digital Diagnotics Monitoring) and 4 IEEE802.3af High Power over Ethernet (PoE) Power Sourcing Equipment (PSE). Using external 48VDC or 55VDC power inputs through terminal block, data and power can be transmitted to a Powered Device (PD) over the same twisted-pair Ethernet cable. The hardened EX74000 series supports advanced features such as 802.1Q VLAN, MAC-based Trunking, IP-Multicast IGMP Snooping, Rapid Spanning Tree for Redundancy, QoS for priority queuing, and port mirroring. Users may choose among SNMP/RMON, Web browser, or Telnet for remote monitoring and configuration. It also supports rate control, which allows users to set the maximum bandwidth on each port individually. |
