Anyone have experience powering Long Range Adapters (LR1002-1ET / LR1002-1EC) from an NVR Hik V5 7716? How do you force the NVR switch to auto negotiate the POE?
Power Long Range (coax) Adapters from NVR?

The Hikvision NVR simply follows the standards-based PoE handshake methods.
It won't supply power unless the PD (powered device) responds as per the standard.
With the caveat that I'm guessing a bit here ...
But the adaptor spec says 'passive PoE.
If that means that it simply must receive a fixed 48v down the inbound ethernet cable then there will be a compatibility problem.
Thanks
Adaptor spec says 'Supports IEEE802.3af and IEEE8022.3at Power Supply Standards'
Hikvision NVR switch also says '16, RJ-45 10/100 Mbps self-adaptive Ethernet interface, IEEE 802.3 af/at'.
Still couldn't get these to work and had to employ a simple POE switch upstream.
Caveat emptor.

Yeah probably should have specified all Dahua for this but got spooked by their pull out of the US market (where we shop).
Is your NVR an ePOE Dahua model?

Of course Dahua markets these extenders so I'm guessing they made sure their NVR switches would negotiate with them. Tried 2 different Hik NVRs and neither would even light the power LED. $50 TP Link switch connected immediately.
