6-Port Gigabit PoE Switch with VLAN and 90W 802.3bt High PoE portCompliant with the latest PoE technology 802.3bt/at/af, the AirLive IG-641BT-1.25G Gigabit switch supports high power, port 1 up to 90W (802.3bt), and Port 2~4 up to 30W/each (802.3at), with 1 SFP port and 1 Gigabit PD Uplink port which can receive up to 60W PoE Power and power on the switch. The switch automatically detectsand adaptively supplies needed power to connected PoE devices; for non-PoE devices, it will just transfer data intelligently.For the application where management is not really needed but VLAN is useful and the budget is controlled, the AirLive IG-641BT can help. Using a smart DIP-switch to turn the IG-641BT VLAN feature and PoE Watchdog on. Moreover, Port 4 can support data and power up to 250meter at 10Mbps over Cat.5e cable that helps where a PD is installed far away, and the power source is hard to get.


  • All 6-port, each port delivers Gigabit high speed
  • Extend the network further with 1 x SFP slots that accept fiber transceivers and go beyond the limits of Ethernet
  • High PoE power supports 802.3bt PoE++ up to 90W for port 1.
  • Automatically detect and offer power for connected PD
  • Supports the PoE power supply of the uplink port, which can receive power up to 60W.
  • Support PoE watchdog when in VLAN mode
  • VLAN port Isolation
  • Extended transmission of up to 250M (PoE port 4) in Extend Mode

Efficient PoE Watchdog technologyThe Switch IG-641BT-1.25G supports PoE Watchdog when the Dip Switch is switched to either VLAN mode or Extend mode. After the PoE Watchdog function is enabled, the IG-641BT-1.25G switch works as a virtual security guard. When the POE port is continuously powered but there is no traffic, the POE watchdog will be triggered. After 2 minutes of detection, the power supply will be stopped and then powered on.The PoE watchdog is particularly useful for cameras. For example, when the switch is turned on, it will recognize the front camera 24 hours a day, 7 days a week. If there is no data traffic from the camera, the camera is considered to be frozen, and the PoE watchdog is used to restart the front camera to solve the problem. *Note: Function available in VLAN or Extend Mode

Wide temperature coverage from -40°C ~ 85°CThe IG-641BT-1.25G switch can operate from -40°C ~ 85°C. And each POE port has 6KV surge protection. It is the ideal solution for applications that work under a hash environment and require stable network and PoE power, such as parking lot or IP surveillance. The IG-641BT-1.25G has a rugged high strength compact size metal case that is rated at IP40 and has a DIN35 Rail connection making it ideal for network use in heavy industries or factories. It can be placed in almost any harsh environment.

Fiber backbone for Long DistanceExtend the network further with SPF slots. vUse the IG-641BT-1.25G as a backbone of our network can reach up to 20KM in speed 1250Mbps data transmission.

Dual Power InputsThe IG-641BT-1.25G supports 2 DC power inputs for power redundancy. That greatly improves the reliability and uptime of a sensor network in a harsh environment. When one of the DC power inputs fails, the second input will continue to power on the switch. The Switch supports input of DC 48 ~ 55V.

802.3BT 90W High Power outputAirLive IGM-642BT-2.5G Industrial switch supports the high-power output PoE++ at 90W for port 1. This higher output allows it to power more devices than just an IP  camera or Access point. The 90W PoE can be used to power on high-power needed PoE Systems, Digital Signage or even PoE LED lighting and much more. Giving you much more flexibility on the usage, as you are no longer restricted to only 30W.

Industrial Application Harsh EnvironmentAirLive IG-641BT-1.25G Industrial switch meets the high standard demands of providing reliable networking connectivity, able to withstand harsh industrial environment, and cost-effectively.
