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 PoE out port (PoE-Out). The access
point 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 PoE-Out 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 Ethernet MAC addresses are printed on a label on the bottom of the access point under
the LEDs.
Tip The access point senses the Ethernet and power signals and automatically switches internal
circuitry to match the cable connections.
Caution To provide inline PoE, you must use the 1550 series power injector. Other power
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.
Cable Option
The factory-orderable cable option provides a cable modem and Power-over-Cable (POC) capabilities
for the access point for high-speed data transfer and Internet access. When the cable option is selected
and installed, the access point uses its F-type cable connector to receive both data and power. Data is
passed between wireless clients on the mesh network to the cable company network via the internal
cable modem of the access point. In this configuration, the access point receives operating power from
the cable. For detailed installation information, see the Cisco Aironet 1550 Series Outdoor Access
Point Hardware Installation Guide. Configuration information can be found in the controller
configuration guide of the controller you are using.
