RB 751u 2hnd POE problem

Thu Jul 26, 2012 8:33 am

hello

i try to connect RB 751u 2hnd to an HP v1905 poe switch iهn order to obtain electricity for the mikrotik device from the HP switch using POE port , but i failed to do so.
the question is that my mikrotik RB 751u 2hnd can receive electricity from POE port, or send electricity ? and how to do that , is that require special switch, special cabling?

thank you :)

RB751 isn't compatible with PoE switches, it uses own standard (special power supply or adapter).

RB isn't 803.2af compliant. You have to use an passive POE injector, or an RB-POE-CON, which converts 803.2af into MT's POE implementation...

You can use POE-CON to connect RB751U with 802.3.af switch.

Well thx sergejs :)

i want to install about (40) 751u 2hnd in a school are all connected to a mikrotik firewall
and my goal that to lower the number of tapes and electricity outlets, because the electricity is so bad here in my country
i want to run away from the problems of the power play, and interruption of electricity
so it is possible to have power for the 751u 2hnd from the poe RB750UP switch? and this will run good ?
