Statement 10402 Introduction to the Access PointThe Cisco Aironet 1550 Series Outdoor Mesh Access Point (hereafter called the access point) is a ruggedized outdoor access designed for service in mesh networks. The 1550 series leverages 802.11n technology with integrated radio and external antennas. The 1550 outdoor platform consists of (Multiple Input Multiple Output) MIMO WLAN radios and optional integrated spectrum intelligence (Clean Air).CleanAir provides full 11n data rates while detecting, locating, classifying and mitigating radio frequency (RF) interference to provide the best client experience possible. CleanAir technology on the outdoor 11n platform mitigates WiFi and non-WiFi interference for both the access and backhaul radios.

5 DRAFTThe 1550 AP series offers multi-band 2.4 GHz, and 5 GHz configurations with an option to configure access and backhaul radios. The 1550 outdoor radios are called 2.4GHz MIMO radios and 5GHz MIMO radios. The radios can be configured for one or two radio operation. The 2.4GHz radios are used primarily for local access and the 5 GHz radios for wireless backhaul in the Mesh. The 1550 series supports the modularity of the 1520 series and allows flexibility in radio configuration. In addition to full interoperability with 802.11n clients, the 1550 series interoperates with legacy clients and offers enhanced backhaul performance. The 1550 series can also be configured with an integrated DOCSIS 3.0 cable modem.Note The 4.9-GHz Public Safety band requires a license and may be used only by qualified Public Safety operators as defined in section 90.20 of the FCC rules. The access point is a standalone unit that can be cable strand or tower mounted. The access point can also operate as a relay node for other access points not directly connected to a wired network. Intelligent wireless routing is provided by the patent-pending Adaptive Wireless Path Protocol (AWPP). This enables each access point to identify its neighbors and intelligently choose the optimal path to the wired network by calculating the cost of each path in terms of signal strength and the number of hops required to get to a controller. The access point is configured, monitored, and operated through a Cisco wireless LAN controller (hereafter called a controller) as described in the appropriate Cisco Wireless LAN Controller Configuration Guide. The Cisco Mesh Networking Solution Deployment Guide describes how to plan and initially configure the Cisco mesh network, which supports wireless point-to-point, point-to-multipoint, and mesh deployments. The controllers use a browser-based management system, a command-line interface (CLI), or the Cisco Wireless Control System (WCS) network management system to manage the controller and the associated access points. The access point is compliant with Wi-Fi Protected Access 2 (WPA2) and employs hardware-based Advanced Encryption Standard (AES) encryption between wireless nodes to provide end-to-end security.3 Unpacking the Access PointNote When you are unpacking the access point, do not remove the foam blocks attached to the antenna connectors.

The 2GHz b/g/n radio operates in 2.4 GHz ISM band. It supports channels 1-11 in US, 1-13 in Europe, and 1-13 in Japan. It has two transmitters with a maximum total output power of 25dBm for 802.11b/g/n operation. Output power is configurable to 5 levels. It has three receivers that enable maximum-ratio combining (MRC).

13 DRAFTNote The FCC limits the amount of power this device can transmit. Power transmitted is a combination of the amplification of the signal and the antenna gain. The access point has been designed to operate with the antennas listed below having a maximum gain of 4 dBi for 2.5-GHz and 7 dBi for 5-GHz antennas. Antennas not included in this list or having a higher gain are strictly prohibited for use with the access point. The required antenna impedance is 50 ohms.”Note To reduce potential radio interference to other users, the antenna type and its gain should be chosen so that the equivalent subtropical radiated power (EIRP) is not more than required for successful communication.Antenna ConfigurationsTwo antenna configurations are available, based on how the access point is mounted. The cable strand mounting configuration uses three antennas and the tower mount configuration uses four antennas. Table 1 identifies the antenna ports used and explains the configurations.Table 1 Antenna Ports and Configurations Antenna Port Product ConfigurationCable Strand Mount (Two Antenna Receive MRC Access and One Backhaul)Pole Mount (Three Antenna Receive MRC Access and One Backhaul)12.4-GHz receive only 5-GHz receive and transmit25-GHz transmit and receive No connection32.4-GHz transmit and receive 2.4-GHz receive only4No connection 2.4-GHz receive only5No connection No connection6No connection 2.4-GHz transmit and receiveMIMO Antenna OptionsThe MIMO antenna replaces the aluminum cover on the radio-side of the housing. The MIMO antenna is constructed of a polycarbonate radome, aluminum ground plane, antenna support brackets and 3dual-band dipole antennas, each with an integral coax cable. Dual-band antennas cover the

14DRAFTfrequency ranges 2.400-2.483 GHz and 5.250-5.850 GHz. The dual-band antennas span the WiMAX band 2.496- 2.690 GHz and extend the upper band to 5.250-5.875 GHz. Each 3-inch dual band antenna element is a vertically polarized omni-directional antenna with nominal peak antenna gain of 2 dBi for the 2.4 GHz antenna and 4 dBi for the 5 GHz. See Figure 4 for installed 1550 series MIMO antennas. Peak gain of the 2.4 GHz antenna is at 20 degrees down from the horizon, the 5 GHz is at 10 degrees down. The pigtail coax cable from each dual-band antenna will connect to the 5 GHz MIMO radio by a MCX right-angle male connector. The LP MIMO antenna requires the 5 GHz MIMO radio to be mounted 90 degrees to that of the non-PoC 1550 MIMO radio, as illustrated in Figure 4.

15 DRAFTFigure 4 1550 Series MIMO Radio with Dual-Band Antennas InstalledMIMO External Antenna ConfigurationsThe 1550 series support several MIMO external antenna configurations. The external antenna option for dual band 2.4/5 GHz operation is listed in Table 2. All the external antennas have DC shorts to ground for lightning protection. The 1550 series will provide up to six N-connectors for external connection to antennas.

18DRAFTWarningThis equipment must be externally grounded using a customer-supplied ground wire before power is applied. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Statement 366WarningDo not work on the system or connect or disconnect cables during periods of lightning activity. Statement 1001Caution Do not place the power injector in an unprotected outdoor environment because water could get into the power injector and cause a short circuit and possible fire.The 1550 series access point supports the following power sources: • AC power—100 to 480 VAC • Quazi-AC power-over-cable (POC)—40 to 90 V • External 12 VDC power • Power-over-Ethernet—1550 power injector • Internal 6 ampere-hour battery backup • Alternative power source prioritization for custom applications is selectable with software upgradeWarningConnect the unit only to DC power source that complies with the Safety Extra-Low Voltage (SELV) requirements in IEC 60950 based safety standards Statement 1033The 1550 series access point can be connected to more than one power source. The access point detects available input sources and switches to the preferred power source using the following prioritization: • AC or POC power • External DC power • 1520 power injector PoE power • Internal battery powerWarningThis unit might have more than one power supply connection. All connections must be removed to de-energize the unit. Statement 1028

19 DRAFTWarningTo reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord. Statement 1023Caution To provide inline PoE, you must use the 1520 series power injector. Other power injectors, PoE switches, and 802.3af power sources cannot provide adequate power, which may cause the access point to malfunction and cause over-current conditions at the power source. You must ensure that the switch port connected to the access point has PoE turned off.Caution Do not install the power injector and the power outdoors. They must be installed indoors.Caution When the access point is installed outdoors or in a wet or damp location, the AC branch circuit that is powering the access point should be provided with ground fault protection (GFCI), as required by Article 210 of the National Electrical Code (NEC).Three AC power cord options are available: • 40-ft (12.2-m) power cord for light pole installations in the US and Canada. One end of the power cord is terminated with an access point AC power connector and the other end is terminated with an AC plug (AIR-CORD-R3P-50NA=). • 40-ft (12.2-m) power cord for use outside the US and Canada. One end of the power cord is terminated with an access point AC power connector and the other end is unterminated. (AIR-CORD-R3P-50UE=). • 4-ft (1.2-m) streetlight power tap adapter for light pole installations in the US and Canada (AIR-PWR-ST-LT-R3P=).Ethernet (PoE) PortsThe access point supports an Ethernet uplink port (POE-In) and a downlink port (POE-Out). The access point’s Ethernet uplink port uses an RJ-45 connector (with weatherproofing) to link the access point to the 10BASE-T, 100BASE-T, or 1000BASE-T network. The Ethernet cable is used to send and receive Ethernet data and to optionally supply inline 56-VDC power from the power injector. The minimum length of this cable must be not less than 10 feet (3 meters).

20DRAFTThe access point’s downlink Ethernet port uses an RJ-45 connector (with weatherproofing) to provide LAN connectivity and IEEE 802.3af power to a peripheral customer device, such as a camera or sensor gateway. The BVI MAC addresses are printed on the label on the side of the access point Tip 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 series power injector. Other power injectors, PoE switches, and 802.3af power sources can not provide adequate power, which may cause the access point to malfunction and cause possible over-current conditions at the power source.Cable OptionThe factory-orderable cable option provides a cable modem and Power-over-Cable capabilities for the access point for high-speed data transfer and Internet access. When the cable option is installed, the access point uses its F-type cable connection to receive both data and power. Data is passed between wireless clients on the mesh network to the cable company’s network via the access point’s internal cable modem. In this configuration, the access point receives operating power from the cable. For detailed installation information, see the Cisco Aironet 1550 Series Outdoor Access Point Hardware Installation Guide. Configuration information can be found in the controller configuration guide of the controller you are using.Fiber OptionWarningClass 1 laser product. Statement 1008The factory-orderable fiber option provides a fiber input and output capability. Fiber is data is transmitted and received over a single-strand fiber cable which is connected to the access point using: • 100BASE-BX10-U fiber Rugged small factor pluggable (SFP) module • 1000BASELX single-mode Rugged SFP module • 1000BaseSX multimode Rugged SFP moduleNote SFP modules are not hot-swappable.

21 DRAFTFor convenience, two fiber connections are available on the access point. One connection is on the bottom of the unit (shown on Figure 1) and the other on the left side (shown on Figure 2). Client data is passed to the network controller through the fiber connection via a fiber capable switch. For detailed installation information about the fiber option, see the Cisco Aironet 1550 Series Outdoor Mesh Access Point Hardware Installation Guide. Configuration information can be found in the controller configuration guide of the controller you are using.6 Network Deployment ExamplesThe access point is a wireless device designed for wireless client access and point-to-point bridging, point-to-multipoint bridging, and point-to-multipoint mesh wireless connectivity. The access point provides 5-GHz backhaul capability to link with another access point to reach a wired network connection or to provide repeater operations for other access points.The access point plays two primary radio roles: a root access point (hereafter called a RAP) or a non-root access point (hereafter called a MAP), which is the default role of all access points. When the access point has a wired Ethernet or cable connector connection to the controller (through a switch), the radio role is called a RAP. In order to be considered a RAP, the access point must be configured as a RAP. A RAP is a parent node to any bridging or mesh network. A controller can support one or more RAPs, each one parenting the same or different wireless 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 have a wired Ethernet connection to the controller (through a switch), the radio role is called a MAP. The MAPs have a wireless connection (through the backhaul interface) to other MAPs and finally to a RAP which has an Ethernet connection through a switch to the controller. MAPs may also have a wired Ethernet connection to a local LAN and serve as a bridge endpoint for that LAN (using a point-to-point or point-to-multipoint bridge connection).Wireless BackhaulThe 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 as shown in Figure 6. 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. Lightweight access point protocol (LWAPP) control traffic is also transferred over this bridged link.

22DRAFTFigure 6 Access Point Backhaul Example148438(5.8 Ghz)(2.4 Ghz)Point-to-Point BridgingThe access points can be used to extend a remote network by using the 5-GHz backhaul radio to bridge the two network segments as shown in Figure 7. To support Ethernet bridging, you must enable bridging on the controller for each access point.Wireless client access is supported; however, if bridging between tall buildings, the 2.4-Ghz wireless coverage area may be limited and possibly not suitable for direct wireless client access.Figure 7 Point-to-Point Bridging Example148440Point-to-Multipoint BridgingThe access points can be used as a RAP to connect multiple remote MAPs with their associated wired networks. 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 2.4-Ghz wireless coverage area may be limited and possibly not suitable for direct wireless client access.

23 DRAFTFigure 8 illustrates an example of access point-to-multipoint bridging.Figure 8 Point-to-Multipoint Bridging Example148439Mesh NetworkThe access point is 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. In the mesh network, the links between the access points are referred to as the backhaul links.Intelligent wireless routing is provided by the patent-pending Adaptive Wireless Path protocol (AWPP). This enables each MAP to identify its neighbors and intelligently choose the optimal path to the RAP with the wired network connection by calculating the cost of each path in terms of signal strength and the number of hops required to get to a controller with signal strength given priority since signal strength determines the bandwidth available for backhaul. Figure 9 illustrates a typical mesh configuration using MAPs and RAPs.

24DRAFTFigure 9 Typical Mesh Configuration Using MAPs and RAPs148441WCSNetworkRAPMAP 1 MAP 2 MAP 3MAP 4 MAP 6MAP 5MAP 7 MAP 8 MAP 9Layer 3 Network OperationThe 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 10 illustrates a typical Layer-3 wireless network configuration containing access points and a controller.

25 DRAFTFigure 10 Typical Layer 3 Access Point Network Configuration Example1484587 Preparing the Access PointThe access point is a radio device which is susceptible to common causes of interference that can reduce throughput and range. Follow these basic guidelines to ensure the best possible performance: • For information on planning and initially configuring your Cisco mesh network, refer to the Cisco Mesh Networking Solution Deployment Guide or the Cisco Aironet 1500 Series Wireless Mesh AP Design Guide. These documents are available on cisco.com. • Do not install the access point in an area where structures, trees, or hills obstruct radio signals to and from the access point. • You can install the access point at any height, but best throughput is achieved when the access points are mounted at the same height.Note To perform path loss calculation and to determine how far apart to install access points, consult an RF planning expert.Site SurveysCisco recommends that you perform a site survey before installing the equipment. A site survey reveals problems that can be resolved before the network is operational. Because 802.11a is unlicensed, there may be sources of interference from other 802.11a wireless devices (especially in multi-tenant buildings) that could degrade your 802.11 signals. A site survey can determine if such interference exists. A proper site survey involves temporarily setting up mesh links and taking measurements to determine whether your antenna calculations are accurate. Determine the correct locations and antenna types before you drill holes and route cables and mounting equipment.

26DRAFTTip When power is not readily available during a site survey, use an unrestricted power supply (UPS) to temporarily power the mesh link.Consider the following operating and environmental conditions when performing a site survey: • How far is your wireless link? • Has a previous site survey been conducted? • Do you have a clear Fresnel zone between the access points or radio line of sight? • What is the minimum acceptable data rate within the link? • Do you have the correct antenna? • Do you have access to both of the mesh site locations? • Do you have the proper permits, if required? • Do you have a partner? Never attempt to survey or work alone on a roof or tower. • Have you configured the access points before you go onsite? It is always easier to resolve configurations or device problems first. • Do you have the proper tools and equipment to complete your survey?Avoiding Damage to Radios in a Testing EnvironmentThe 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 higher than the normal the receiver’s operating range, packet error rate (PER) performance is degraded. At even higher levels, the receiver can be permanently damaged.To avoid receiver damage and PER degradation, 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 conservative estimates. Required separation distances for damage and performance degradation levels in actual deployments will be less due to non line-of-sight propagation conditions. • Reduce the configured transmit power to the minimum level. • Use directional antennas and keep them pointed away from each other.

27 DRAFT • Cable the radios together using a combination of attenuators, combiners, or splitters to achieve a total attenuation of at least 60 dB.For a radiated test bed, the following equation describes the relationships among transmit power, antenna gain, attenuation, and receiver sensitivity:txpwr + tx gain + rx gain - [attenuation due to antenna spacing] < max rx input levelWhere:txpwr = Radio transmit power leveltx gain = transmitter antenna gainrx gain = receiver antenna gainFor a conducted test bed, the following equation describes the relationships among transmit power, antenna gain, and receiver sensitivity:txpwr - [attenuation due to coaxial components] < max rx input levelCaution Under no circumstances should you connect the antenna port from one access point to the antenna port of another access point without using an RF attenuator. If you connect antenna ports you must not exceed the maximum survivable receive level of 0 dBm. Never exceed 0 dBm or damage to the access point can occur. Using attenuators, combiners, and splitters having a total of at least 60 dB of attenuation ensures that the receiver is not damaged and PER performance is not degraded.Before You BeginWarningRead the installation instructions before connecting the system to the power source. Statement 1004Before you begin the installation process: • Become familiar with the procedures for mounting the access point. • Become familiar with the access point connections (Figure 1 on page 9, Figure 2 on page 10, and Figure 3 on page 11). • Verify that the switch you are using to connect the controller is configured properly.

28DRAFTNote For additional installation, mounting and safety information for the outdoor mesh access point, see the Cisco Aironet 1550 Series Outdoor Mesh Access Point Hardware Installation Guide, which is available on Cisco.com, and Safety Warnings for Cisco Aironet 1520 Series Outdoor Mesh Access Points, which accompanies this guide. 8 Deploying the Access PointWarningDo not operate the unit near unshielded blasting caps or in an explosive environment unless the device has been modified to be especially qualified for such use. Statement 364The access point is deployed on Layer 3 networks. Layer 3is the default mode for a newly configured wireless LAN controller. This guide assumes that you will be deploying your access point on a Layer 3 network and a DHCP server is available.Before deploying the access point, make sure the controller to which the access point will associate is properly configured by performing the following operations: • Make sure that the wireless LAN controller is set to Layer 3 mode • Verify the wireless LAN controller software version • Record the access point BVI MAC address • Enter the access point BVI MAC address to the wireless LAN controller filter listVerifying the Wireless LAN Controller ModeFollow these steps to verify that the wireless LAN 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://. A login screen appears.Step 2 Enter your username and password. The default case-sensitive username and password are admin and admin. The Summary page appears.Step 3 From the top menu bar, click CONTROLLER. The Controller General page appears.Step 4 Verify that the LWAPP Transport Mode is set to Layer 3. If it is not, change it to Layer 3 and click Apply.Step 5 Save any changes you made.

29 DRAFTStep 6 From the menu bar, click MONITOR to return to the Monitor Summary page.Verifying the Wireless LAN Controller Software VersionOn the Summary page, you can verify the software version that the wireless LAN controller is running. If a version update is necessary, refer to the appropriate controller configuration documentation.Recording the Access Point MAC AddressUse a text file to record the MAC address of all the access points you intend to deploy in your network. Having a file of access point MAC addresses will be of considerable value for future testing. While you are compiling the list, you might want to change the name of the access point to something you can easily remember. The name can contain up to 32 characters. The following example, fisher_street:ea:co contains the last four HEX characters of the access point MAC address.Adding the Access Point MAC Address to the Wireless LAN Controller Filter ListThe wireless LAN controller maintains an access point authorization MAC address list and responds to discovery requests from access points on that list. Follow these steps to add the access point MAC address (or MAC addresses) to the Wireless LAN controller filter list:Step 1 If you are not logged onto the wireless LAN controller, log on now. The Summary page appears.Step 2 On the menu bar, click SECURITY. The Security RADIUS Authentication Server page appears.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 appears.Step 5 Enter the MAC address of the access point in the MAC Address field. You can also use the config macfilter add command to add a MAC filter entry to the controller.Step 6 Select a WLAN ID or Any WLAN from the WLAN ID pop-up menu.Step 7 Enter a description (32 characters maximum) of the access point in the Description field. Step 8 Choose an interface from the Interface Name pop-up menu.Step 9 Click Apply.Step 10 Repeat this process to add other access points to the list.

30DRAFTNote You can also use the controller CLI command config macfilter add to add a MAC filter entry on the controller.Step 11 On the menu bar, click Monitor to return to the Monitor Summary page.Verifying Controller AssociationTo verify that your access point is associated to the wireless LAN controller, perform these steps:Step 1 Log into your controller web interface (https) using a web browser.Step 2 Click Wireless and verify that your access point MAC address is listed under Ethernet MAC.Step 3 Log out of the controller and close your web browser.Deployment NotesUsing a DHCP Server in a Layer 3 Mesh NetworkTo use a DHCP server in a Layer 3 mesh network, make sure the wireless LAN controller is in Layer 3 mode. You must also configure DHCP option 43 on the DHCP server. After the controller is restarted, the access point receives IP addresses from the DHCP server.Configuring DHCP Option 43You can use DHCP Option 43 to provide a list of controller IP addresses to the access points, enabling each access point to find and join a controller. This section contains a DHCP Option 43 configuration example on a Microsoft Windows 2003 Enterprise DHCP server for use with Cisco Aironet lightweight access points. Additional information about Microsoft DHCP Option 43 is available on Cisco.com at the following URL:http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_example09186a00808714fe.shtmlDHCP Option 43 server implementation information for Cisco IOS is available at cisco.com at the following URL:

31 DRAFThttp://www.cisco.com/en/US/docs/wireless/technology/controller/deployment/guide/dep.html#wp1068287Note In DHCP Option 43, you should use the IP address of the controller management interface.Note DHCP Option 43 is limited to one access point type per DHCP pool. You must configure a separate DHCP pool for each access point type.Cisco Aironet 1000 and 1500 (1505 and 1510) series access points use a comma-separated string format for DHCP Option 43. Other Cisco Aironet access points use the type-length-value (TLV) format for DHCP Option 43. DHCP servers must be programmed to return the option based on the access point’s DHCP Vendor Class Identifier (VCI) string (DHCP Option 60). The VCI strings for Cisco access points capable of operating in lightweight mode are listed in Table 3:

48DRAFTGuidelines for Using the Access PointYou should keep these guidelines in mind when you use the access point: • The access points can only communicate with controllers and cannot operate independently. • The access point communicates only with controllers and does not support Wireless Domain Services (WDS). The access points cannot communicate with WDS devices. However, the controller provides functionality equivalent to WDS when an access point associates to it. • The access point supports Layer 3 LWAPP communications with the controllers. In Layer 3 operation, the access point and the controller can be on the same or different subnets. The access point communicates with the controller using standard IP packets. Layer 3 operation is scalable and is recommended by Cisco. Unless it has a static IP address, a Layer 3 access point on a different subnet than the controller requires a DHCP server on the access point subnet and a route to the controller. The route to the controller must have destination UDP ports 12222 and 12223 open for LWAPP communications. The routes to the primary, secondary, and tertiary controllers must allow IP packet fragments. • Before deploying your mesh access points ensure that the following has been done: –Your controllers are connected to switch ports that are configured as trunk ports. –Your mesh access points are connected to switch ports that are configured as untagged access ports. –A DHCP server is reachable by your mesh access points and has been configured with Option 43. Option 43 is used to provide the IP addresses of the Management Interfaces of your controllers. Typically, a DHCP server can be configured on a Cisco Layer 3 switch or router. –Optionally a DNS server can be configured to enable a local domain Cisco LWAPP controller (CISCO-LWAPP-CONTROLLER.<local domain>) to resolve to the IP address of the Management Interface of your controller. –Your controllers are configured and reachable by the mesh access points. –Your controllers are configured with the MAC addresses of the mesh access points.Checking the LEDsFour LEDs, located between the PoE-In and PoE-Out connectors, monitor the status of the access point’s power, uplinks, and radios. Figure 12 identifies and describes the LED functions. Table 7 provides additional LED information.

50DRAFTNote Regarding LED status colors, it is expected that there will be small variations in color intensity and hue from unit to unit. This is within the normal range of the LED manufacturer’s specifications and is not a defect.See the Cisco Aironet 1550 Series Outdoor Mesh Access Point Hardware Installation Guide for a detailed description of the LEDs and additional troubleshooting tips.Misconfigured Access Point IP addressIP address misconfiguration can occur when you are re-addressing a segment of your mesh network and you start at the mesh access point connected to the wired network (RAP). To avoid this problem, always start the IP addressing changes from the farthest access point and work your way back to the root access point. This problem might also happen if you move equipment such as uninstalling an mesh access point and then redeploying with a different IP subnet in another physical location on the mesh network.Another option to fix this misconfigured IP address is to physically take a controller in Layer 3 mode with a root access point to the location of the misconfigured mesh access point. Set the bridge group name for the root access point to match the misconfigured access point. Add the access point’s MAC address to the controller’s filter list. When the misconfigured access point appears in the controller’s Summary page, configure the access point with an IP address.If you are using a static IP address on the access point and plan on redeploying the access point on another subnet, perform a clear config command from the controller for that access point while it is joined before you remove it from the network.Red Firmware failure –Firmware failureCycling red/green LWAPP discovery – –1.
