Is it possible to turn off the red light, so the status of the ethernet conection would be seen
now you can’t see if the device has an ethernet conection or not
I’m also interested in current(mA) consumption monitor, when will it be implemented?
I have tested RB750UP with powering 2 ubiquiti nanostation an 1 ubiquity rocket with 24V backup power suply (55W Single Output with Battery Charger(UPS Function)
AD-55 series + 2X 12V 12AH leasd battery) only on battery power. After 4h, voltage droped to 21.4V and 1 nanostation (eth2)and 1 rocket (eth3) shut down the power with 1 nanostation (eth5) still working it worked for 2 more hours then I poverd back to 220
Is this some safety feture or what? Why did the RB750UP shut down the POE output?
when voltage drops 500mA limit stays the same, as result power output drops too, if at 24V * 500mA = 12W, then at 20V output is only 10W etc. if that is over the budget then power is turned off.
Also, when there is load, there is small additional power drop, so as result, when one or more devices go off, voltage rises a bit thus enabling it to work further.
Also, if you are powering devices with wireless, then lower data rates use more power then higher ones, so if link goes bad and AP/client has to transmit frames over wireless link at lower data rates, it uses more power.
Ubiquity nanostation and rocket uses 0.1 - 0.15 A, so the 500mA limit is not excided. The most usage I’ve seen is RB600 with R52H it uses 0.3 A, and it stayed powerd, when the nanostation and rocket lost power.
Also In voltage monitor is aprox. 2V diference from the voltage mesurd with volt meter, when there is 23.6V shown by the volt meter(with the load on), mikrotik RB750IP voltage monitor shows 22V.
Voltage mesured by the volt meter comming from the POE port is 23V.
I would like to try to buy a 750UP to power up 1 ubiquiti power bridge and 2 Rocket M5.
Do you think that RB750UP will be able to power these 3 devices ?
I will inject 24V on RB750UP max power 60W.
