Introduction
Introduction
This document covers the Cisco 702W Series Access Points theory of operation and installation as part
of a Cisco Wireless LAN (WLAN) solution. Subjects related include:
•Overview of the AP-702W.
•Physicals / Hardware details, mounting options, bracket choices, and installation considerations.
•Powering options, antenna patterns, switched ports, AP placement, and so on.
This document is intended for trained and experienced technical personnel familiar with the existing
Cisco Wireless Networking Group (WNG) product line and features.
AP-702W
Overview
The Cisco AP-702W Series Access Point targets Multi-Dwelling-Unit (MDU) deployments, such as
customers requiring support for Higher Education, Hospitality, college dorm-rooms, K-12 classrooms,
and healthcare, seeking a high-performance in-room Wireless + Wired Access Device.
The AP-702W is a wall plate Access Point (AP) designed to combine the features of an AP and a four
port switch into a single unit with a small footprint targeting education and hospitality markets.
Note Do not confuse AP-702W with AP-702i, which is a conventional AP designed for ceiling mounting and
does not have additional Ethernet ports for device connectivity.
AP-702W Features Include
•Combined hardware switch and wireless AP.
•4 x 10/100/1000BASE-T local Ethernet ports for wired device connectivity.
•1 local Ethernet port includes Power-Over-Ethernet (PoE) out.
•1 x 10/100/1000BASE-T Power-Over-Ethernet (PoE) uplink port.
•802.11n 2x2:2 simultaneous dual band 2.4 GHz and 5 GHz support.
•Compact form factor designed for in-room installations.
•Integrated 2.4 GHz 2 dBi and 5 GHz 4 dBi antennas.
•Small footprint 6 x 4 x 1.6 inches.
The AP-702W, while similar to the Cisco AP-700 series with regards to performance, is different and
embodies a wall mount design and should not be ceiling mounted.

AP-702W Installation
As mentioned in Figure 1, the AP-702W is designed to be mounted on an existing electrical box or
network outlet box. Because of the vent holes on the device, it is not designed for ceiling mounting but
may be mounted on the wall close to the ceiling so long as there is at least a 3-inch gap between the top
of the unit and the ceiling for heat dissipation.
The default wall bracket is designed to allow the four switched ports to be accessible for downstream
devices. It is not recommended (or supported) to use the downstream switched ports to connect
additional APs or other heavy upstream traffic devices such as additional switches and so on.
The Ethernet ports in AP-702W are disabled by default and can be enabled by using the
enable_port port id command, where port ID can range from 1 - 4.
Note By default, the 4 switched ports on the AP are disabled.

AP-702W Powering Options
The AP-702W is designed to accept power via Power over Ethernet (PoE) or by using a local “brick”
style power supply. Because the AP-702W has the ability to provide PoE out on port #4, the unit draws
in an excess of 15.4 Watts (802.3af) specification, and therefore it is recommended that PoE+, 802.3at,
or local power supply Cisco part number AIR-PWR-C be used.
When the AP is first powered on, if powered via Power over Ethernet (PoE) it will negotiate power using
the Cisco Discovery Protocol (CDP) and/or Link Layer Discovery Protocol (LLDP). By using these
methods, the AP-702W will ask for 15.4 W initially starting up with that amount of power. During the
Power On Self Test (POST) it will discover that it has a port on PSE LAN4 capable of producing PoE
out, so it will then attempt to negotiate for additional Ethernet power via the same methods for that port.
If additional power is available, it will switch from 802.3af (15.4 W power) to PoE Plus / 802.3at power.
The amount of power it negotiates varies with the version of code being used.
If the code version is 7.6, it will request 30 W. If the code version is 8.x, it will request 22.1 W. If the
AP is successful in negotiating the higher PoE power from an 802.3at or PoE+ source, the AP-702W will
then come up and allow the PSE LAN4 port to provide Class 2 PoE out at 6.49 W (7W with cable losses).
If the AP is not successful in negotiating the higher PoE power value from 802.3at or PoE+, it will
continue to use 15.4 W (802.3af) power and continue with PoE out on the PSE LAN4 port disabled.

AP-702W
Note At this time there is no method of disabling the “ask” for additional power if high power is
present. There is a feature request to better handle this in the future, but if the goal is to have the
AP-702W not ask for additional power, then a work around would be to configure the powering
device to only allocate 15.4 W (802.3af) power on the port that the AP-702W is attached.
‘
Local power supply AIR-PWR-C= may be used. Do not use AIR-PWR-B.
Note If PoE+ or 802.3at power source is present, the AP will negotiate higher power. If this is not
desired, a work around is to limit PoE on switch to 15.4 W until addressed in release 8.1.
Note If the unit is powered by 802.3at (PoE+) then the device can deliver PoE out of port 4 at 7 W
output. If 802.3af (15.4 W) is desired out of Port 4, then the local power supply AIR-PWR-C
must be used.

Earlier Cisco-Aironet power supplies are rated at 48 VDC @ 380 mA. These earlier supplies do not have
enough current to allow the AP-702W to provide PoE out on port 4.
AP-702W Antenna System
The AP-702W has two integrated dual band antennas designed for best performance when mounted to
an electrical box in a wall mount configuration.
Figure 9 Antenna 1 and Antenna 2 mounted on the Top and Left Side of the AP-702W
Avoid mounting the AP in locations where metal objects would be near the antennas.
The antenna gain is 2 dBi @ 2.4 GHz and 4 dBi @ 5 GHz designed to radiate in a front Omni-directional
pattern with 25 dB of isolation between bands.

As mentioned, the AP-702W is designed for wall mounting and so it may have a slightly smaller cell
coverage area than a conventional AP that is typically mounted physically higher on a ceiling. This is
fine, because Cisco Radio Resource Management (RRM) will learn and properly balance out the channel
assignments, and clients will roam smoothly when there is a mixture of ceiling and wall mounted APs.

Roaming, channel assignments, and RF power all function well with the AP-702W. Its antenna
technology comprising two transmit radios and two receive radios in each band called 2x2 in a Multiple
Input Multiple Output (MIMO) configuration support two spatial streams (2SS) together referenced as
2x2:2. For more on the benefits of 802.11n, see the following URL:

AP 702W Switched Ports
Figure 14 Ethernet Switched Ports AP-702W
The 4 x 10/100/1000BASE-T local Ethernet ports support half and full duplex mode, auto-negotiation,
and MDI/MDIX Auto-Sensing. Devices you connect must support auto-negotiation if you connect with
another mode, for example—hard configured speed and so on. The port may not be enabled, and in some
cases the ports are not managed, depending on the version of code, for example 7.6.100.120 (the initial
release).

AP-702W
Note VLAN support is available in release 8.0. See Configuring VLANs in Release 8.0 at the end of
this guide for details.
For now, (until more control is added in the software) all the LAN ports are locally switched and mapped
to the 702W VLAN, and do not appear on the Wireless LAN Controller or AP.
Initially, the ports are disabled and may be enabled manually via the CLI.
This was done to minimize any security risks. Here are the CLI commands to enable the ports.
(Cisco Controller)> config ap lan <port id> <enable/disable> <AP-NAME>
(Cisco Controller)> show ap lan <port id> <AP-NAME>
(Cisco Controller)> show ap lan port-summary <AP-NAME>
Due to the early release of the 7.6.100.120 code, the enable/disable all command was not integrated,
so you must configure each AP and each port, one by one. With code 8.0 and later, a more refined control
along with VLAN support is being added to these ports.
When configuring the AP-702W for PoE out on port 4, it is important to verify that you have at least
16.1 W when powering the unit by PoE. So, the AP will require PoE+ or higher power than what can be
provided by 802.3af (15.4 W).
To troubleshoot PoE, check the PoE status under the Wireless > Advanced tab and verify if the power
is higher than medium (15.4 W).
Figure 15 PoE out on Port 4 will not happen if PoE Status is only Medium Power (15.4 W)

Figure 16 Verifying FULL Power on the Controller
The PoE needs to be at full power. You can use PoE+, 802.3at, local power supply, or Cisco Power
Injector 4 Cisco part number AIR-PWR-INJ4 which provides higher PoE power. The AP-702W will not
be able to provide PoE out if a 15.4 W injector, such as the AIR-PWR-INJ5 or 802.3af power, is used.
For more on PoE, see Table 1.

Tips for Wireless Installations
1. It is all about placing the AP as reasonably close to the actual users as possible.
2. Make sure that you have coverage, (to a known requirement) and compensate for nulls or dead spots
regardless of what product you choose to deploy. This is called a site survey.
3. Installations should be done based on lessons learned from the site survey, the better the survey the
less likely connectivity problems will occur.
4. Cisco has an advanced services team that can perform WLAN surveys or help with the wireless
design if a partner is not available or able to do the same.
5. Do not mount antennas against metal objects. Similar to a light bulb, antennas work best when there
are no obstructions in the path.
AP-702W AP Spacing Recommendations
If you have a Wi-Fi device such as an AP and you are going to use another AP in the vicinity on a
different channel, it is recommended that you space each AP apart by approximately 6 feet (2 meters).
Avoid clustering the APs or the antennas from different APs together because this could cause
degradation in performance. The recommended distance is based on the assumption that both devices
operate in the unlicensed band and do not transmit RF energy more than 23 dB, that is, 200 mW. If higher
power is used, space the devices farther apart.
Should you have other devices that transmit, especially if they operate in the same frequency ranges, for
example, frequency hopping legacy APs or other devices that operate with close frequency to those of
the APs (think below or above the 2.4 and 5 GHz band), you should consider moving or separating the
devices as far apart as can reasonably be done. After you have done this, check for interference by testing
both devices at the same time under heavy utilization (load) and then characterize each system
independently to see how much, if any, degradation exists.
Warning In order to comply with FCC, EU, and EFTA RF exposure limits, antennas should be located at a
minimum of 7.9 inches (20 cm) or more from the body of all persons. See the installation guide under
declaration of conformity for more on this.

Cisco Aironet Series 702W Access Point Deployment Guide
Site Survey Considerations
Installations in IDF Closets (Telecommunications or other Electrical
Equipment)
When installing APs near other electrical or telecommunications equipment, keep all wiring and metal
away from the antennas and avoid placing the antennas near electrical lines. Do not route wiring
electrical or Ethernet in the near field (6-15 inches) of the antenna. Try to refrain from installing the AP
in the electrical closet because the best place for the AP is as close to the users as possible/practical. If
you have remote antenna cables from in a closet, you may be required to use Plenum rated cable (see
local fire/safety regulations for more on this).
Below are a few URLs for understanding interference:

http://www.cisco.com/en/US/prod/collateral/wireless/ps5678/ps10981/white_paper_c11-609300.html
Site Survey Considerations
It is considered a good practice to conduct a site survey to assess cell coverage and look for problem
areas such as poor RF coverage or high retries. Always try to install the AP as close to the actual users
as possible or practical to do so.
If you have done a site survey with a previous product, chances are that the survey is still valid and you
only need to perform simple checks to verify that coverage holes or problem areas do not exist.
Figure 18 Heat Maps and coverage areas are fairly uniform between different APs

20
Cisco Aironet Series 702W Access Point Deployment Guide
Configuring VLANs in Release 8.0
While cell sizes are similar, each higher end AP model employs methods that allow the user to
experience higher data rate connectivity with less retries. For example, using higher MCS rates, Spatial
streams, or Cisco’s ClientLink beam-forming technology. So, the take away is that the client experiences
a higher performance and faster connectivity, but it is not designed to change the actual cellular coverage
area so surveys maintain their validity across different AP models.
Configuring VLANs in Release 8.0
Configuring VLANs on the Network
Overview of the Network
The AP 702W uplink port connected to the controller must be set to trunk. The AP will set its IP address
(and therefore its management interface) in the untagged / native VLAN. The AP VLAN is assigned by
setting the right native VLAN on the trunk.
Client traffic can be assigned to different VLANs by assigning these VLANs on the AP 702W's trunk
port and then configuring the 4 Ethernet ports specifying the VLAN per port on the Wireless controller
software AP configuration.
Wired client traffic will be locally switched on the AP port. Wireless traffic and CAPWAP traffic will be
sent to the controller. Once this is done, then enabling access on the 702W AP is done.
Configuring VLANs on AP 702W
From code release 8.0.75.1 onward, you can configure LAN ports and VLAN assignments.
Before setting VLANs, enable the LED state on the 702W AP, so you can confirm whether the client is
connected because the ports and LEDs are in disabled state by default.
To enable the LED state from the CLI, use the command: config ap led-state enable
See the following screen shot to enable the LED state from the GUI:
