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
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.
