I have an unmanaged POE switch to which I need to connect a RUT241. This switch uses IEEE802.3af/802.3at (Netgear GS108LP). I see that the RUT241 uses pins 4, 5, 7 and 8 for passive POE, so can I connect those devices together using a home made Ethernet cable, with only pins 1, 2, 3 and 6 wired, to get the whole thing working without burning the RUT241?
For this one, yes, if PoE is not needed for your requirement, then you can use a custom UTP cable where wires for pins 4, 5, 7, and 8 are not connected.
As you are already aware, the mentioned pins are used for PoE. Not including the wires for it (Blues and Browns) will make sure that the electricity will not flow
Just make sure that the cable is crimped properly to ensure that you will have stable connectivity.
Thank you for your reply.
The device wiki page should mention that, because the current warning could scare some potential customers.
I actually already have the appropriate cable:
This one was provided with a low cost Chinese router and should be good enough to suit my need.
Since it doesn’t have the mentioned wires on the mentioned pins. That should work just fine. May I ask a feedback for this one to ensure that your RUT241 is connected working just fine? This is for future reference for other Teltonika users.
I confirm that my RUT241 works as expected when connected to my Netgear GS108LP POE switch with an Ethernet cable that only has two pairs wired on pins 1, 2, 3 and 6.
