Note

To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord. Statement 1023

To provide inline PoE, you must use the 1500 power injector (AIR-PWRINJ1500-2=). Other power 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 1500 power injector (AIR-PWRINJ1500-2=) must be used in an indoor environment only.

When the access point is installed outdoors or in a wet or damp location, the AC branch circuit that is powering the access point should be provided with ground fault protection (GFCI), as required by Article 210 of the National Electrical Code (NEC).

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.

The following AC power cord options are available:

•40-ft (12.2-m) power cord for light pole installations in the US and Canada. One end of the power cord is terminated with an access point AC power connector and the other end is terminated with an AC plug (AIR-CORD-R3P-40NA=).

•40-ft (12.2-m) power cord for use outside the US and Canada. One end of the power cord is terminated with an access point AC power connector and the other end is unterminated. (AIR-CORD-R3P-40UE=).

•4-ft (1.2-m) streetlight power tap adapter for light pole installations in the US and Canada (AIR-PWR-ST-LT-R3P=).

Cable Modem (POC)

The access point POC cable modem configuration contains an internal cable modem for connection to the cable network from the pole-mounted cable lines. The access point can be powered using the 40-to 90-VAC (quasi-square wave AC) power provided by the cable network.

The cable modem supports these main features:

•Data Over Cable Service Interface Specifications (DOCSIS)3.0

•Backward compatibility with existing DOCSIS 1.1 and 1.0 networks

Ethernet (PoE) Ports

The access point supports an Ethernet uplink port (POE-In) and a downlink port (POE-Out). The access point 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.
