1. Power can be supplied via DC input (PWR connector) or PoE inline (PoE IN port), but not both.

2. We recommend that you not use two power options concurrently, but no harm results if both are present.

3. If using both power inputs, DC input (PWR connector) power takes precedence and PoE inline power is not used.

4. Power supply redundancy is not supported.

The access point requires a DC power supply. To power the access point with a DC power supply, you connect the DC power to the PWR connector on the bottom panel. The DC input voltage range is +12 to +48 VDC (-20%, +25%).

The PWR connector is an M12 A-code, 4-pin (male) connector. See Power Port, on page 75 and DC Input and PoE IN Specifications,

on page 67.

PoE OUT Port

Note

The PoE OUT port is only supported when the access point is powered over the PWR port. When powered over the PoE IN port, PoE OUT functionality is not supported.

The PoE OUT port is a 10/100/1000 BASE-T port with an M12 X-code connector. The PoE OUT port supplies PoE inline DC power to power external devices. The PoE OUT port pin-out conforms to Alternative A-MDIX mode.

Note

PoE inline power supports IEEE 802.3af compliant devices and delivers up to 15.4 W of PoE.

For more information about the PoE OUT, PoE IN, and DC input, see DC Input and PoE IN Specifications, on page 67.

PoE IN Port

The PoE IN port is a 10/100/1000 BASE-T port with an M12 X-code connector. The port has auto-sensing and auto-MDIX capabilities.

Note

The PoE IN port is an alternate power input to DC input over the PWR port.

• Power the access point over the PWR port to enable the PoE OUT port.

• When powered over the PoE IN port, PoE OUT functionality is not supported.

For more information, see DC Input and PoE IN Specifications, on page 67.

Protective Vent Port

The protective vent port relieves pressure inside the access point chassis possibly caused by changing temperatures in the installation environment. The vent prevents pressure from building up and damaging enclosure seals and potentially exposing sensitive components to water. The vent also protects the access point interior from dust, dirt, water, and other environmental elements.

Note

If the vent is removed or damaged, the access point is subject to moisture damage.

Reset Button

You use the reset button for configuration or image recovery. The reset button is under the protective vent port. To access the reset button:

1. Use a 5/8" socket to remove the protective vent.

2. Disconnect power (the power jack for external power or the Ethernet cable for in-line power) from the access point.

3. Press and hold the RESET button while you reconnect power to the access point.

4. Press the reset button.

• Hold the RESET button until the Status LED turns blinking blue (usually, pushed for 30 seconds) to reset the access point to its factory settings.

• Hold the RESET button until the Status LED turns solid Red (usually, pushed for 50 seconds) to do image recovery.

5. Replace the protective vent using 5/8" socket.

6. Torque the protective vent to 5-7 inch-lbs.

Console Port

You can connect the access point to a PC or laptop through the RJ45 CON port. The RJ45 CON port uses the Cisco console port RJ45-to-DB9 cable (Cisco PN 72-3383-01).

A cable port seal covers the CON port. This liquid-tight plug protects the access point from environmental elements. Ensure that the plug is installed during normal operation or when unit is unattended. You can remove and install the port plug with a 1/2" (13 mm) socket. Torque it to 6-7 ft-lbs

For more information, see Console Port, on page 77.

Ground Stud

The ground stud is the access point ground. You use screws to attach the wired grounding lug to the ground stud. Connect the other end of the ground wire to an earth ground such as a grounding rod or appropriate ground point on a grounded pole.

Top Panel Components

This section describes the top panel components.

Antenna Port

The antenna connector is a type N female coaxial connector.

Installation Guidelines

Because the access point is a radio device, it is susceptible to common causes of interference that can reduce throughput and range. Follow these guidelines to ensure the best possible performance:

• For information on planning and initially configuring your Cisco Mesh network, refer to the Cisco Wireless Mesh Access Points,

Design and Deployment Guide.

• Review the FCC Guidelines for Installation and Operation of Outdoor Wireless LAN Devices (U-NII devices) Operating in the 5470-5725 MHz Band Data Sheet at:

http://www.cisco.com/c/en/us/products/collateral/routers/3200-series-rugged-integrated-services-routers-isr/data_sheet_c78-647116.html

The above document provides guidelines to mitigate interference to Federal Aviation Administration (FAA) Terminal Doppler Weather Radar (TDWR) as well as details on registering your access point with the Wireless Internet Service Providers Association (WISPA).

• Perform a site survey before beginning the installation.

• Install the access point in an area where structures, trees, or hills do not obstruct radio signals to and from the devices.

• For information on priming a Cisco universal access point, see the Cisco Aironet Universal AP Priming and Cisco AirProvision User Guide at: http://www.cisco.com/c/en/us/td/docs/wireless/access_point/ux-ap/guide/uxap-mobapp-g.html

Site Surveys

Every network application is a unique installation. Before installing an access point, perform a site survey to determine the optimum use of networking components and maximize range, coverage, and network performance.

Consider the following operating and environmental conditions when performing a site survey:

• Data rates—Sensitivity and range are inversely proportional to data bit rates. The maximum radio range is achieved at the lowest workable data rate. A decrease in receiver sensitivity occurs as the radio data increases.

• Antenna type and placement—Proper antenna configuration is a critical factor in maximizing radio range. As a general rule, range increases in proportion to antenna height. However, do not place the antenna higher than necessary, because extra height increases potential interference from other unlicensed radio systems and decreases the wireless coverage from the ground.

• Physical environment—Clear or open areas provide better radio range than closed or filled areas.

• Obstructions—Physical obstructions such as buildings, trees, or hills can hinder performance of wireless devices. Avoid locating the devices in a location where an obstruction exists between the sending and receiving antennas.

Unpacking the Components

The typical access point package contains the following items:

• Access point
