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?
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.
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.
