One thing I might want to add is that if you have a 48V power supply on a router that only supports passive poe, you might have some luck powering up an active POE device. I do this with a mikrotik router by forcing POE to ON. This has already worked with 2 802.1af devices I have. No guarantee of course. Cheers, nice video ;-)

Finally
Awesome explanation! I noticed your TSW010 states "possible to power up through first LAN port" I assume that means the port labled 1 not the porr labled 5?
Hello, that's correct. In order to power up the TSW010 using Passive PoE, you must use LAN port 1.
So why would a IEEE 802.3af-2003 PoE Injector (15.4W or 12,95W which can be used from this) connected to LAN Port1 would destroy a RUTX11 as described in the RUTX11 Teltonika wiki? The RUTX11 has a max. of 16W per the specs. This would mean POE+ 802.3at (up to 30W) would be needed, right? But the RUTX11 Wiki says it is not compliant to IEEE 802.3at. This is super confusing. I have in mind to use a IEEE 802.3af-2003 and IEEE 802.3at comply PoE injector using PIN4+5 for 9-50VDC+ and PIN7+8 for 9-50VDV-. So does this work or not?
Hello,
The reason for this limitation is that our routers exclusively support Passive POE. Any other devices connected using a different POE type could potentially cause harm to the port or even the entire device.
If you're interested in utilizing Active POE, we recommend exploring the option of acquiring POE injectors or adapters. These devices can effectively convert Active POE output to Passive POE output, enabling compatibility with our routers.

✌
So pretty. Lithuanian?
The fact that you don't support active PoE is a huge negative for Teltonika.
Hello, we have switches that support Active PoE out. It means that these switches can power up another devices. These switches can be found on our Teltonika Networks page here : teltonika-networks.com/products/switches?page=1&features=1013 However, almost all our devices can be powered up only via passive PoE through the first Ethernet port (LAN1).
Cute host
😊
Indeed ….
@@TeltonikaNetworksthank you for being patient and kind. PoE reminds me of a landline phone I used once, that only required one single (American) telephone cable that powered the entire phone to make it ring!
perhaps an inductor that reacts in kind to the impulse of the Power oE?
She looks like she's about to burst out laughing at any moment, like she's had some funny exchange with the other people in the room 🤣
