Chapter 1 Overview Hardware Features REVIEW DRAFT—CISCO CONFIDENTIAL Caution To provide inline PoE, you must use the 1520 power injector (AIR-PWRINJ1500-2=). Other power injectors, PoE switches, and 802.3af power sources cannot provide adequate power, which can cause the access point to malfunction and cause over-current conditions at the power source. Caution The 1520 power injector (AIR-PWRINJ1500-2=) must be used in an indoor environment only.
Chapter 1 Overview Hardware Features REVIEW DRAFT—CISCO CONFIDENTIAL The Ethernet cable must be a shielded outdoor rated Category 5e (CAT5e) or better cable. The access point senses the Ethernet and power signals and automatically switches internal circuitry to match the cable connections. Caution To provide inline PoE, you must use the 1520 power injector (AIR-PWRINJ1500-2=). Other power injectors, PoE switches, and 802.
Chapter 1 Overview Network Deployment Examples REVIEW DRAFT—CISCO CONFIDENTIAL • Streetlight power tap adapter (AIR-PWR-ST-LT-R3P=)—connects to the light control connector on a streetlight pole and provides AC power to the access point. • 1520 power injector (AIR-PWRINJ1500-2=)—provides PoE to the access point. • 40-ft (12.2-m) power cord for light pole installations in the US and Canada (AIR-CORD-R3P-40NA=)—provides AC power to the access point.
Chapter 1 Overview Network Deployment Examples REVIEW DRAFT—CISCO CONFIDENTIAL Wireless Backhaul The access point supports wireless backhaul capability using the 5-GHz radio to bridge to another access point to reach a wired network connection to a controller (see Figure 1-5). The access point connected to the wired network is considered a RAP in this configuration. The remote access point is considered a MAP and transfers wireless client traffic to the RAP for transfer to the wired network.
Chapter 1 Overview Network Deployment Examples REVIEW DRAFT—CISCO CONFIDENTIAL Point-to-Multipoint Bridging The access points can be used as a RAP to connect multiple remote MAPs with their associated wired networks (see Figure 1-7). By default, this capability is turned-off for all access points. To support Ethernet bridging, you must enable bridging on the controller for each access point. Wireless client access can be provided over the bridging link; however, if bridging between tall buildings, the 2.
Chapter 1 Overview Network Deployment Examples REVIEW DRAFT—CISCO CONFIDENTIAL Mesh Network The access points are typically deployed in a mesh network configuration. In a typical mesh deployment, one or more RAPs have a wired network connection through a switch to a controller. Other remote MAPs without wired network connections use the backhaul feature to optimally link to a RAP that is connected to the wired network.
Chapter 1 Overview Network Deployment Examples REVIEW DRAFT—CISCO CONFIDENTIAL Layer 3 Network Operation The access points support Layer 3 network operation. Access points and controllers in Layer 3 configurations use IP addresses and UDP packets, which can be routed through large networks. Layer 3 operation is scalable and recommended by Cisco. Figure 1-9 illustrates a typical Layer-3 wireless network configuration containing access points and a controller.

Chapter 2 Mounting Instructions Safety Information REVIEW DRAFT—CISCO CONFIDENTIAL Safety Precautions Warning In order to comply with radio frequency (RF) exposure limits, the antennas for this product should be positioned no less than 6.56 ft (2 m) from your body or nearby persons. Statement 339 Warning The AC power supply has double pole/neutral fusing. Statement 188 Warning Do not work on the system or connect or disconnect cables during periods of lightning activity.
Chapter 2 Mounting Instructions Safety Information REVIEW DRAFT—CISCO CONFIDENTIAL Warning Caution Do not locate the antenna near overhead power lines or other electric light or power circuits, or where it can come into contact with such circuits. When installing the antenna, take extreme care not to come into contact with such circuits, because they may cause serious injury or death. For proper installation and grounding of the antenna, please refer to national and local codes (for example, U.S.
Chapter 2 Mounting Instructions Avoiding Damage to Radios in a Testing Environment REVIEW DRAFT—CISCO CONFIDENTIAL Avoiding Damage to Radios in a Testing Environment The radios on outdoor units (bridges) have higher transmit power levels than radios on indoor units (access points). When you test high power radios in a link, you must avoid exceeding the receiver’s maximum receive input level. At levels above the normal operating range, packet error rate (PER) performance is degraded.
Chapter 2 Mounting Instructions Installation Guidelines REVIEW DRAFT—CISCO CONFIDENTIAL 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 basic guidelines to ensure the best possible performance: Note • For information on planning and initially configuring your Cisco Mesh network, refer to the Deployment Guide: Cisco Mesh Networking Solution.
Chapter 2 Mounting Instructions Installation Guidelines REVIEW DRAFT—CISCO CONFIDENTIAL Before Beginning the Installation Before you begin the installation process: • Ensure that a site survey has been performed. • Ensure that your network infrastructure devices are operational and properly configured. • Ensure that your controllers are connected to switch trunk ports. • Ensure that your switch is configured with untagged access ports for connecting your access points.
