To provide inline PoE, you must use the 1520 power injector (AIR-PWRINJ1500-2=). Other power
Caution
injectors, PoE switches, and 802.3af power sources cannot provide adequate power, which can cause the
access point to malfunction and cause over-current conditions at the power source.
The 1520 power injector (AIR-PWRINJ1500-2=) must be used in an indoor environment only.

In the cable configuration, the cable modem is activated only when the access point is powered by POC

or external 12 VDC power. When using only PoE power, the cable modem is deactivated.
When the access point is installed outdoors or in a wet or damp location, the AC branch circuit that is
Caution
powering the access point should be provided with ground fault protection (GFCI), as required by
Article 210 of the National Electrical Code (NEC).
The Ethernet cable from the power injector to the access point (PoE-in port) must be not less than 10 ft
(3.1 m).
The AC power cord options are listed below:

Ethernet Ports
The access point supports a PoE-in port and a PoE-out port. The access point's PoE-in port uses an RJ-45
connector (with a liquid tight adapter) to link the access point to the 10/100/1000BASE-T network. The
Ethernet cable is used to send and receive Ethernet data and to optionally supply inline 56-VDC power
from the power injector.
The access point's PoE-out (10/100/1000BASE-T) port uses an RJ-45 connector (with a liquid tight
adapter) to provide LAN connectivity and IEEE 802.3af power to a single peripheral customer device,
such as a camera or sensor gateway. The PoE-out port should not be connected to a switch or hub.
The PoE-out port is disabled when the access point is powered by the power injector.
Note
The Ethernet MAC addresses is printed on the bottom of the access point under the LEDs (refer to the
