Introduction
AP-702W
Overview
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.
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.
AP-702W
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.

1. This is the power required at the PSE, which is a switch or injector.
2. In the 7.6 version code, the draw is 30 W and in the 8.0 code, the draw is now reduced to 22.1 W.
802.3at PoE+ PWRINJ4
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.
