Use POE out of mikrotik router RB951Ui-2HnD to power Picostation M2

I am trying to setup a wireless network and i intend to use a RB951Ui-2HnD mikrotik router to power a picostation M2 via the POE out port.

Please is this safe (i saw a post that said plugging a picostation into a mikrotik poe "fried" it) and will it work considering the electrical details of the devices


Relevant details
RB951Ui-2HnD

The RB951Ui-2HnD is a wireless SOHO AP with a new generation Atheros CPU and more processing power. It has five Ethernet ports, one USB 2.0 port and a high power 2.4GHz 1000mW 802.11b/g/n wireless AP with antennas built in.
It has a 600MHz CPU,128MB of RAM and PoE output function for port #5 - it can power other PoE capable devices with the same voltage as applied
to the unit. Maximum load on the port is 500mA.
Supported input voltage7 V - 31 V
Max Power consumptionUp to 7W

Picostation M2

Max. Power Consumption
8 W
Power Supply (PoE)
15V, 0.8A Power Adapter (Included)
Power Method
Passive Power over Ethernet (Pairs 4, 5+; 7, 8 Return)

thanks in advance of your quick response

Hello
i offer you that do not it.

If you supply your RB951Ui with 15V, it will probably work without problems.
But if you put the original Mikrotik 24V adapter to work, you will probably fry your Picostation.

ohk. thanks for the enlightenment, I really appreciate.

Picostation can work up to 24v but first radios where delivered with 15v POE adapters. After some time, all radios had 24v adapters. So it will work.

It may work but IMHO supplying 24V to a device running at UP TO 24V has some risks, depending on how they engineered the power converter in the device. These wall warts are not to precise, so you may get a +10 voltage on the power supply, a -10% voltage tolerance on the device…
In my opinion, it is best to supply the devices in the mid range of their accepted power range, and never on their upper limit.

Anyhow, if they supply the Picostations with 24V power adapters, it is probably safe and will work.

you should use Independent adapter

Could you bring some arguments against it? Passive PoE generally works between Mikrotik and Ubiquiti devices as long as voltage requirements are met, since both companies use the same approach (I wanted to say standards, but that would be an overstatement).
