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.
8
Cisco IW3702 Access Point Getting Started Guide
Overview
Notes: When powering the access point:
— Power can be supplied via DC input (PWR connector) or PoE inline (PoE IN port), but not both.
— We recommend that you not use two power options concurrently, but no harm results if both are
present.
— If using both power inputs, DC input (PWR connector) power takes precedence and PoE inline
power is not used.
— 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 front panel (see Figure 1 on page 4 and Figure 4 on page 7). 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, page 50 and DC Input and PoE IN
Specifications, page 42.
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, page 42.
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.
Notes: 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, page 42.
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.

Cisco IW3702 Access Point Getting Started Guide
Overview
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:
1. Use a 5/8" socket to remove the protective vent.
2. Press 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.
3. Replace the protective vent using 5/8" socket.
4. 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, page 53.
Ground Stud
The ground stud is the access point ground. You use screws to attach the wired grounding lug to the ground stud (Figure 6 on
page 16). 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.
Rear Panel Components
This section describes the rear panel components shown in Figure 5 on page 11.
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.
Note: Do not attach third-party radios using these hard points.

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.
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.

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.
