Hi, I’m interested to install this AP in a room where is already present a PoE camera, the router supports on eth1 af/at as well as the camera, but on eth2 provides only passive PoE, which for some reasons may be compatible with at PoE mode. Will the camera work?
The PoE has a good protection agains short circuits, failure between pairs and so on, it controls current and load at the beginning, if something goes wrong it interrupts it till the problem isn’t solved. What about this Passive PoE? Can I spoil the router if a short will come?
Indicates Mikrotik devices with PoE out support Overload and short circuit protection.
Possibly also the switches safety circuit protection will trigger.
Take care plugging non PoE devices into ether 2 of the map if it has PoE out turned on.
(eg. When testing)
They may not like having 48 volts being applied to their ethernet port.
Maybe label the ethernet cable from ether 2 to the camera indicating it is passive poe.
I suspect camera will not work, at least I’ve not seen af/at only cameras working on passive poe. To answer, if you can connect camera to passive poe port for testing, I have done it without bad consequences, but take it on your risk of course.
thanks for answers, unfortunately I have any supply device available which output continious 48V to connect it to camera (4-5 pair (+) and 7-8 (-), actually I don’t see any reasons why it shouldn’t work, I did it in past with a router af/at and it worked, so why not camera?
If you have this equipment, may you kindly try it? Thank you!
The answer is, yes it supports a PoE cameras on the eth2 but both PoE (router input and camera input) should be AT mode, AF mode is not supported. So be sure all 4 pairs of cable are connected
802.3at is a sort of superset of 802.3af (in the sense that a 802.3at PSE can provide power to both 802.3af and 802.3at PD’s) , the number of cables used or not used does not change between them, it is 802.3bt that uses 8 wires instead.
