Na mups jsem cekal s nadejemi, ale jde pouzit jen na mikrotik na kratsim kabelu. Pri vypadku to jede pochopitelne jen z 12V baterky, takze pro UBNT nevhodne.
Mne to z baterky ide nepochopitelnych cca. 24V :
(Nepametam si presne kolko som mal na meraku, ale urcite to nebolo 12V)
Pozri si datasheet
10/100/1000 Ethernet ports 2
Short detection time ~50 us
Short protection delay ~20 ms
After short recovery time ~1 s
Measurement update time ~45 ms
PoE in 12 - 28 V
PoE out
Depends on power source:
When input 12 - 24 V = 24 V
When input > 24 V = same as input
When powered by battery = 20 V
DC in 12 - 28 V
Battery connector Female tab terminal 6.3 x 0.8 mm
Battery charging current 1 A max
PoE out max current limit 700 mA
Po vlne nevole zrejme Mikrotici zmenili mups. Puvodni specifikace byla viz odkaz. Parametry jsem resil s product managerem i4wifi a furt jsem nemohl pochopit, k cemu je ten paskvil dobry. (Potvrdil mi, ze pri prepnuti na baterii bude mit vystup 12V (napeti baterie), prestoze nominalni napajeni mups bude treba 24V) Nove to tedy trochu vylepsili, ale stejne 700 mA je zalostne malo.

toto je novy datasheet: https://i.mt.lv/routerboard/files/mUPS-170830105108.pdf
The mUPS is a smart PoE injector with a 12 V battery connector. It works just like a Gigabit PoE
injector, but when power is lost, it switches over to the 12 V battery. Even if your power source is
28 V, the connected RouterBOARD will not reboot when the power source is lost, it will switch over
to the 12 V battery transparently. The LEDs indicate DC line or battery
usage, the charging of battery and low battery level (<50%).
In RouterOs it is possible to detect when running on battery power
by monitoring the input voltage with scripting, since the voltage will
change without a RouterOS reboot.
The mUPS is a simple and compact device to make your network
more reliable, or for situations where stable power input is not
available, like solar or automotive installations.

na stole to utiahlo nejakych 17W musel som pripojit ziarovku lebo 2x LHG a 2x SXTsq davalo malo watov. Nasadil som to na jeden bod ja na tom Omnitik UP a z neho 1x mANT15 1xSXT HG5 ac a 1x omnitik 4 dni to ide ok ale pisu ze ten mUPS ma Router OS ale neda sa do toho nijak dostat tak som na omnitiku spravil script na pokles napetia na 20v
