Ethernet (Poe) Ports - Cisco Aironet 1520 Series Getting Started Manual

When the access point is installed outdoors or in a wet or damp location, the AC branch
Caution
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).
Three 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-50NA=).
• 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-50UE=).
• 4-ft (1.2-m) streetlight power tap adapter for light pole installations in the US and Canada
(AIR-PWR-ST-LT-R3P=).

Ethernet (PoE) Ports

The access point supports an Ethernet uplink port (POE-In) and a downlink port (POE-Out). The
access point's Ethernet uplink port uses an RJ-45 connector (with weatherproofing) to link the access
point to the 10BASE-T, 100BASE-T, or 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
minimum length of this cable must be not less than 10 feet (3 meters).
The access point's downlink Ethernet port uses an RJ-45 connector (with weatherproofing) to provide
LAN connectivity and IEEE 802.3af power to a peripheral customer device, such as a camera or sensor
gateway. The BVI MAC addresses are printed on the label on the side of the access point
The access point senses the Ethernet and power signals and automatically switches internal

circuitry to match the cable connections.
To provide inline PoE, you must use the 1520 series power injector. Other power
Caution
injectors, PoE switches, and 802.3af power sources can not provide adequate power,
which may cause the access point to malfunction and cause possible over-current
conditions at the power source.
