The mUPS is a PoE injector with battery backup capability 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.
You can use the mUPS with any single 12V battery (AGM, Gel, Lead Acid,
regular car batteries, deep cycle marine batteries, etc.).
Note: 12 V battery not included and must be mounted elsewhere. PoE out
max current limit is 700 mA @ 24 V; 1 A @ 20 V (when powered by
