2 1 About this Guide This guide is designed to familiarize y ourself with your Cisco Aironet 1520 Series Outd oor Mesh Access Point and prepare it for use in your wireles s network. Due to the complexity and number of product options available, this guide does not provide detailed mounting and configuration instructions.
3 Declaration of Conformity with Re gard to the EU Di rective 1999/5/EC (R&TTE Directive) This declaration is only valid for configurations (combinations of software, firmware and hardware) provided and/or supported by Cisco Systems.
4 War n in g This equipment must b e externally grounded using a c ustomer -supplied ground wire before power is applied . Contact the appropriate electrical inspection autho rity or an electrician if you are uncertain that suitable ground ing is available.
5 The access point is a standalone unit that can be cable strand or tower mounted. The access point ca n also operate as a relay node for other access po ints not directly connected to a wired network. Intelligent wireless rou ting is prov ided by the pa tent-pending Adaptive Wireless Path Protocol (A WPP).

9 Figure 3 shows the access point right side conn ections. Figure 3 A ccess Point Right Side Co nnections Radio Operation The 2.4-GHz radio supports three antennas fo r mu lti-input, single output (MISO) operation. The radio uses three receivers to support maximu m ratio combining (MRC) to enhance receiver performance.
10 External Antennas War n in g In order to comply wi th radio frequency (RF) exposure limits, the antennas for this product should be po sitioned no less than 6.
11 Note T o reduce potential radi o interference to other us ers, the antenna type and its gain should b e chosen so that the equivalent subtropical radia t ed power (EIRP) is not more than required for successful communicati on. T able 1 lists the supported external 2.
12 Power War n in g Installation of the equipme nt must comply with local and national electrical codes. Statement 1074 War n in g This equipment must b e externally grounded using a c ustomer -supplied ground wire before power is applied .
13 War n in g Connect the unit only to DC power source that complies with the Safety Extra-Low V oltage (SEL V) requirements in IEC 60950 based safety standards Statement 1033 • Internal 6 ampere-hour battery The access point can be connected to more than one power source.
14 Caution When the a ccess point is installed outdoors or in a wet or damp location, the AC branch circuit that is powering the access point sh ould be provided with ground fault protection (GFCI), as required by Article 210 of the National Electrical Code (NEC).
15 Cable Option The factory-orderable cable option provides a cabl e modem a nd Power -over -Cable capabilities for th e access point for high-speed data tr ansfer and Internet access. When the cable option is insta lled, the access point uses its F-type cable connection to re cei ve both data and power .
16 RAPs, each one parenting the same or different wir el ess networks. There can be more than one RAP for the same mesh network for redundancy . RAPs and MAPs can support wireless clients on the 2.4-GHz band. When the access point does not ha ve a wired Ethernet connection to the controller (through a swi tch), the radio role is called a MAP .
17 Figure 5 P o int-to-P oint Bridging Example Point-to-Multipoint Bridging The access points can be used as a RAP to connect multiple remote MAPs with their a ssociated wired networks. By default this capability is turned-off fo r all access points. T o s upport Ethernet bri dging, you must enable bridging on the controller for each access point.
18 Mesh Network The access point is typically deployed in a mesh ne twork configuration. In a typical mesh deployment, one or more RAPs have a wired network connection through a switch to a controller . Othe r remote MAPs without wired network connections use the backhaul feature to optimally link to a RAP that is connected to the wired network.
19 Layer 3 Network Operation The access points support Layer 3 network operat ion. 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 Ci sco.
20 Site Surveys Cisco recommends that you perform a si te survey before installing the equipment. A site survey reveals problems that can be resolved befo re the network is operational. Beca use 802.11a is unlicensed, there may be sources of interf erence from other 802.
21 T o av oid receiver damage and PER deg radation, you can use one of the following techniques: • Separate the omnidirectional antennas by at least 2 ft (0.6 m) to avoid receiver damage or by at least 25 ft (7.6 m) to avoid PER degradation. Note These distances assume free space path loss and are conservativ e estimates.
22 Before You Begin War n in g Read the installation instru ctions before connecting the sy stem to the power source. Statement 1004 Before you begin the installation p rocess: • Become familiar with the procedur es for mounting the access point.
23 Verifying the Wireless LAN Controller Mode Follow these steps to verify tha t the wirel ess LA N controller mode is set to Layer 3: Step 1 Open your web-browser and enter the IP address of your wireless LAN controller . Be sure to precede the IP address with https://.
24 Step 3 Under AAA in the left frame, click MAC Filtering . The Security MAC Filtering page appears. Step 4 Click New . The MAC Filters New page appe ars. Step 5 Enter the MAC address of the acce ss point in the MAC Address field. Y ou can also use the config macfilter add comma nd to add a MAC filter entry to the controller .
25 Deployment Notes Using a DHCP Server in a Layer 3 Mesh Network T o use a DHCP server in a Layer 3 me sh networ k, make sure the wireless LA N controller is in Layer 3 mode. Y ou must also configure DHCP option 43 on the DHC P server . After the controller is restarted, the access poi nt receives IP addresse s from the DHCP server .
26 T able 3 Lightweight Access P oint V C I Str ings The format of the TL V block for 1100, 1130, 1200, 12 40, 1250, 1300, and 1520 series access p oints is listed below: • T ype: 0xf1 (decimal 241).
27 T o co nfigure DHCP Option 43 for Cisco 1000 and 1500 (1505 and 1510) series lightweight access points in the embedded Cisco IOS DHCP server , follow these steps: Step 1 Enter configuration mode at the Cisco IOS command line interface.
28 T o configure DHCP Option 43 for Cisco Aironet 11 00, 1130, 1200, 1240, 1250, 1300, and 1520 series lightweight access points in the embedded Ci sco IOS DHCP server , follow these steps: Step 1 Enter configuration mode at the Cisco IOS CLI. Step 2 Create the DHCP pool, incl uding the necessary parameters such as default router and name serv er .
