Ubidium supports both power input and power output via Power over Ethernet (PoE). To ensure consistent information, please refer to the Ubidium Datasheet for exact power ratings and supported standards.
Each ethernet port has different capabilities as follows:
| LAN 1 | PoE++ Input | Used to power the Ubidium system via a compatible PoE power source. |
| LAN 2 | PoE Output | Provides power to external devices. This port is always active when Ubidium is powered on and can operate from the internal battery. |
| LAN 3 | PoE+ Output | Provides power to external devices. This port is only active when Ubidium is connected to an external power supply (AC or PoE++ input). |
It is possible to power a secondary Ubidium system using the PoE+ output from LAN 3; however, this does require a sufficient external power input to the system. Note that this daisy-chaining cannot be extended further, as the power delivery to the secondary system will not be sufficient to power a third.
The Green LED on the left of each PoE port indicates the status of the PoE OUT, the following patterns indicate the function of the port.
| Always Off | PoE disabled or not functioning |
| Blinking |
Searching or ready for input/output |
| Always On | Device detected and powered |
Note that devices using a passive PoE input will not work when connected directly to Ubidium, such devices will require an 802.3af (or equivalent) adapter.
