Mikrotik PoE power consistently?

MikroTik PoE hEX nourishes MikroTik RB951Ui-2HnD, the last fifth of ponv PoE-out can be powered by another PoE MikroTik RB951Ui-2HnD?

Well, Yes, and it also has a POE-in. Stick the cable into the POE-out of the first Microta in POE-in the second.

It is possible, subject to unit power PoE hEX.
Pull - all will be well, no.
Soon I will check and will unsubscribe. - juvenal_Gaylord commented on March 19th 20 at 08:57

hEX PoE-out --- PoE-in 951 PoE-out ---- PoE-in 951
1 --- 2 -- 3
The power supply only on the first. And how many of them can be put in parallel ?
Specifications view supply voltage range. Like a maximum of 30 volts input, but different models Microtia can vary this parameter. PSU native 24 volt, right? The first Mikrotik filed 24V on the PoE-out will be a few volts less on the second to PoE-out will still be a few volts less. Take the patch cord razderbanivayut in the middle of a multimeter and measure how many volts are actually between the second and third Microteam. Also see the specifications, what is the minimum voltage you need, like 10V, but I could be wrong. So that the voltage is most likely the fourth is still attached, maybe even the fifth. But the power supply itself (native, regular) can not even pull three Mikrotik. If you do not pull, then buy another PSU capable of more current output. - winfield.OConnell commented on March 19th 20 at 08:59
Also don't forget that the voltage drops significantly on long cable. Ie a short (~1 meter) patch cords you may be run five Mikruykov cascade, but at 100 meters, maybe the second is not to make money, especially if the cable is not copper, and aluminum with copper coating (more resistance). - winfield.OConnell commented on March 19th 20 at 09:02
Do not write a Supplement to my question: in answer to your question! - Kip commented on March 19th 20 at 09:05
@Kip, Thank You. Will take into account. Have not dealt with the interface. - juvenal_Gaylord commented on March 19th 20 at 09:08

Please note that in case of failure of the PSU in the first microte will collapse the whole network.
And Yes, they eat consistently, but the number you need to calculate on the basis of the power/current issued by the power supply and consumed power/current of each individual node in the circuit. When the threshold value is exceeded, I think, is going to suffer the overall performance (errors, up to disconnection of nodes).
As the load on the device 2 and 3 will lead to increased power consumption - juvenal_Gaylord commented on March 19th 20 at 09:01
@juvenal_Gaylord, generally beyond the standards and technical specifications to go out should not the consumption. And about performance -- not so great infrastructure that would lose performance, especially on Microtech, especially on Gigabit ports. - thad32 commented on March 19th 20 at 09:04
