Power Sources and Consumption |
- The AP supports direct DC power and Power over Ethernet (PoE)
- When both power sources are available, DC power takes priority over PoE
- Maximum (worst-case) power consumption:
- DC powered: 20.0W (AP in dual-radio mode), 22.8W (AP in dual-5 GHz mode)
- PoE powered (802.3at): 21.9W (AP in dual-radio mode), 25.1W (AP in dual-5 GHz mode)
- PoE powered (802.3af): 13.5W
- All numbers above are without an external USB device connected. When sourcing the full 5W power budget to such a device, the incremental (worst-case) power consumption for the AP is up to 6W (DC) or 6.6W (PoE)
- Maximum (worst-case) power consumption in idle mode: 11W (DC or PoE)
