|Input power requirements||AP1850: 44 to 57 VDC power supply and power injector: 100 to 240 VAC; 50 to 60 Hz|
Note: When deployed using a Power over Ethernet (PoE) specification, the power drawn from the power sourcing equipment will be higher by some amount, depending on the length of the interconnecting cable.
|Powering options||802.3atEnhanced PoECisco power injector, AIR-PWRINJ4=Cisco local power supply, AIR-PWR-C=Cisco power injector, AIR-PWRINJ5= (Note: this injector supports 802.3af only)802.3af|
Note: If 802.3af PoE is the source of power, (1) the 1852e 2.4-GHz radio will shift to 2×3 from 3×4, (2) The USB port and AUX Ethernet port are disabled on both the 1852i and 1852e.
