Cisco Aironet Series 702W Access Point Deployment Guide, Release 7.6.100.
AP-702W Figure 4 The AP may be secured into the bracket with a hidden tamper resistant screw A sticker covers the screw to prevent detection. Also, a Kensington lock may be used as well. 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.
AP-702W 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. Figure 5 Standard Bracket AIR-AP-BRACKET-W Cisco Aironet Series 702W Access Point Deployment Guide, Release 7.6.100.

AP-702W 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 does draw 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.
AP-702W Figure 8 AIR-PWR-C is the Local Power Supply (Do not use AIR-PWR-A or AIR-PWR-B) Table 2 Output Input Cisco Part # AIR-PWR-C=, higher current than AIR-PWR-B=, needed for POE out port on 702W DC Voltage 48V Rated Current 0.84A Current Range 0.1 ~ 0.84A Rated Power (max.) 40W Ripple and Noise (max.) 240mVp-p Voltage Range 80 ~ 264VAC 113 ~ 370VDC Frequency Range 47 ~ 63HZ Efficiency (Typ.) 91% AC Current (Typ.) 1 A / 115VAC 0.5A / 230VAC INRUSH Current (Typ.
AP-702W 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.

AP-702W Figure 11 AP-702W - Antenna Radiation Patterns for 5 GHz As mentioned, the AP-702 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.
AP-702W Figure 13 Channel Assignments and Power Settings Determined by Cisco RRM 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: http://www.cisco.
AP-702W For now, (until more control is added in the software) all the LAN ports are locally switched, are 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 CLI. This was done to minimize any security risks. Here are the CLI commands to enable the ports.
AP-702W 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. Cisco Aironet Series 702W Access Point Deployment Guide, Release 7.6.100.

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.
General Considerations Regarding Access Points 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.
Misc. Q & A Note More and more clients support these channels all the time, as will the newer 802.11ac clients. Misc. Q & A Q. Which AP is best for Hospitality, dorm rooms, and smaller venues? A. The AP-702W. Q. Which AP is best for manufacturing and warehouse areas? A. Generally speaking the AP 3700e, 3600e, or 2700e would be the first choices because these external antenna models have the highest operating temperature range, -20 to 55C.
