Industrial Ethernet Switch – JetNet 4706f




Ethernet switch JetNet 4706f, the winner of 2008 Computex Outstanding IT Product Award, is the first PoE-plus switch in the world. It is equipped with 4 PoE ports and 2 fiber links. The design of JetNet 4706f is the most suitable model for long-distance IP surveillance where power source is not conveniently located, or wireless surveillance integrated with wireless LAN and WiMax.

  • 2-port 10/100 FX Ethernet and 4-port PoE / PoE-plus
  • 2 Fiber link for long distance transmission
  • DC48V input, 15.4W output for IEEE802.3af PoE IP camera
  • DC55V input, up to 25W output for IEEE802.3at PoE-plusPTZ/IR camera
  • 100W total power budget
  • QoS for prioritized video transmission
  • Optimized IGMP Query, snooping for one-to-many video transmission
  • Port-based VLAN for video traffic isolation
  • MSR guarantees network reliability, 5ms failure recovery
  • IP camera keep alive check and auto failure alarm, recovery
  • IP camera loss/failure alarm through DO, e-mail and SNMP trap
  • Redundant power inputs
  • IP31 rugged aluminum case with great heat dispersing
  • -25~60oC wide operating temperature model available (JetNet 4706f-w)
