AP840-L can support 2 types of power supply 1. 54V DC/1.1 A power input over DC connector: The DC connector accepts 2.1 mm/5.5mm center-positive circular plug. A DC power adapter needs to be purchasedindependently. 2. PoE input over LAN 1: The power source equipment (PSE) complies with IEEE802.3af/at/bt standard (PoE/PoE+/PoE++). Note: 1) If both DC power and PoE are available, DC power is preferred. 2) When powered by 802.3bt (PoE++), the AP operates with optimal performance. 3) When powered by 802.3at (PoE+), the AP starts upnormally. LAN 2 and USB port cannot supply power to external devices. 4) When powered by 802.3af (PoE), the AP starts upnormally. Both 2.4 GHz and 5 GHz radio cards can work only in one spatial stream mode. LAN 2 and USB port cannot supply power to external devices. And for AP840-L , maximum power consumption is 40W DC powered: 40 W PoE powered (802.3af): 12.95 W PoE+ powered (802.3at): 22 W PoE++ powered (802.3bt): 40 W Idle mode: 10.3 W For more information, you can also refer to the Installation Guide: Ruijie Networks | Network Devices and Solutions Provider |
