Disclaimer: TSW101 and Passive PoE devices

There are a couple of options to stay safe when using TSW101 Active PoE with devices that only support Passive PoE:

  • Connect TSW101 and Passive PoE device only via non-PoE Ethernet ports (for example, do not use TSW101 PoE ports with LAN1 ports on Teltonika devices).
  • If there is a need to use LAN1 port on the end device, make sure that TSW101 and the end device are powered from different voltage sources (for example, power both devices from different PSUs, or different batteries).

If TSW101 and a Passive PoE device are connected with common ground, do not use LAN1 port, other ports can be used (refer to image below):
