following priority:
1.
AC power or 24 VDC, either but not both at the same time.
2.
12 VDC (not supported in hazardous locations environments)
3.
Power over Ethernet (1552H only)

Caution
To provide inline PoE, you must use the 1500 power injector (AIR-PWRINJ1500-2=). Other power
injectors, PoE switches, and 802.3af/at power sources cannot provide adequate power, which can cause
the access point to malfunction and cause over-current conditions at the power source.
Caution
The 1500 power injector (AIR-PWRINJ1500-2=) must be used in an indoor environment only, and is not
certified for installation within hazardous locations environments.
