PWR Connectors
There are two options for powering the access point:
•DC input over the PWR connector.
•PoE inline power over the PoE IN port.
10

When powering the access point:Note
1Power can be supplied via DC input (PWR connector) or PoE inline (PoE IN port), but not both.
2We recommend that you not use two power options concurrently, but no harm results if both are
present.
3If using both power inputs, DC input (PWR connector) power takes precedence and PoE inline power
is not used.
4Power 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 72 and DC Input and PoE IN Specifications,
on page 64.
PoE OUT Port
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.
Note
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.
PoE inline power supports IEEE 802.3af compliant devices and delivers up to 15.4 W of PoE.Note
For more information about the PoE OUT, PoE IN, and DC input, see DC Input and PoE IN Specifications, on page 64.
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.
The PoE IN port is an alternate power input to DC input over the PWR port.Note
•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 64.
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.
11

If the vent is removed or damaged, the access point is subject to moisture damage.Note
Reset Button
You use the reset button to reset the access point or reload the software. The reset button is under the protective vent port. To access
the reset button:
1Use a 5/8" socket to remove the protective vent.
2Press the reset button.
•Press the reset button for 3 seconds to reset the access point to its factory settings.
•Press the reset button for 20 seconds to reload the access point software.
3Replace the protective vent using 5/8" socket.
4Torque 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 74.
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.
Hard Points
The hard points are alternate mounting or attachment points for additional equipment such as directional antennas or covers.
12

Do not attach third-party radios using these hard points.Note
Figure 5: Cisco IW3702 Series Access Point Hard Points
Hard points 1/4-20UNC-2B, .45" deep1
Management Options
You can manage the access point using the following options:
•Web browser Interface—Contains management pages to change the wireless device settings, upgrade firmware, and monitor
and configure other wireless devices on the network.
•Cisco IOS command-line interface (CLI)—Configures the access point. You can access the CLI by directly connecting a PC
to the console port, or you can access the CLI using a Telnet session from a remote management station.
13

Installation
You can install the access point on a wall, ceiling or pole, in a cabinet or rack, under a seat, or in a plenum airspace. You can direct
mount, DIN rail mount, or attach the access point on a pole mounting bracket.

Tools and Hardware Required
These tools and hardware are required for access point installation:
•Crimping tool (such as Thomas & Bett part number WT2000, ERG-2001, or equivalent)
•6-gauge copper ground wire
•Wire-stripping tools for stripping 6-gauge wire
•Number 2 Phillips screwdriver

•5/8" (16 mm) socket for protective vent
•5/32" (4 mm) hex key for mounting screws
•Torque wrench (both inch-lbs and ft-lbs)
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
16

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
•Cisco product documentation and translated safety warnings
•Ground lug (Panduit PLCD6-10A-L), screws, and oxide inhibitor (contained in a tube)
•Console cable
•CoaxSeal—Coaxial cable/connector seal tape for N connectors
•Two M12 Ethernet connector caps (installed on the PoE OUT and PoE IN ports)
•One M12 power connector cap (installed on the PWR port)
17

The M12 connector caps are installed on the ports for protection when the AP is shipped. Remove the
caps before using the ports. See the following figure for the locations of each port with M12 cap.
