2 Introduction to the Access Point
The Cisco Aironet 1550 Series Outdoor Mesh Access Point (hereafter called the access point or AP) is
a ruggedized outdoor access designed for service in mesh networks. The 1550 series leverages 802.11n
technology with integrated radio and internal/external antennas. The 1550 outdoor platform consists
of Multiple Input Multiple Output (MIMO) WLAN radios and with 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 on 2.4 GHz radios.
The 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 2.4 GHz MIMO radios and 5 GHz
MIMO radios. The radios can be configured for one or two radio operation. The 2.4 GHz radios are
used primarily for local access and the 5 GHz radios for both local access and wireless backhaul in the
Mesh mode.
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 1552C access point is configured
with an integrated DOCSIS 3.0 cable modem.
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 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 (WLC), referred to as a controller in this document. The WLC is 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-multipoint 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.

combination of the amplification of the signal and the antenna gain. The access point has been
designed to operate with the Cisco provided antennas.
17
Integrated Antenna Option
The 1552C and 1552I models use the Integrated Low Profile Dual-Band 2.4/5 GHz Dipole Antenna
Array. The antenna contains an array of three dual-band dipole antennas. The three dipole antennas are
contained within this single radome, thereby greatly reducing the antennas visual footprint, and greatly
reducing the possibility of snagging the antenna on the cable bundle, the RF cable, or test cables. The
antennas operate over both 2.4 GHz and 5.25 – 5.85 GHz bands. Each of the three dipole antennas is a
dual-band antenna, covering both the 2.4 – 2.483 GHz band, and the 5.25 – 5.85 GHz bands. The antenna
have a peak gain of about 2 dBi at 2.4 GHz and 4 dBi at 5 GHz. The antenna unit is gray weatherproof
radome for outdoor operation.
The low profile integrated antennas are attached to the bottom of a Cisco access point. The 1552C comes
with the option of a C-bracket for strand mounting. The 1552C mesh access point chassis mounting
brackets and low profile antenna all fit within the 30 cm vertical right-of-way for cable strand-mounted
equipment. The antennas are internally connected to the diplexer ports of the outdoor mesh access point
2.4/5 GHz 2x3 MIMO radios.
Figure 9 shows an installed integrated low-profile dual-band (2.4 GHz and 5.25 GHz) 3-element array

The 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
• Power injector PoE power (same as 1520)
• Internal battery power
Warning
This unit might have more than one power supply connection. All connections must be
removed to de-energize the unit. Statement 1028
Warning
To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord.
Statement 1023
Caution
To provide inline PoE, you must use the 1500 power injector (AIR-PWRINJ1500-2=).
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 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-40NA=).
• 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-40UE=).
21
• 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) Ports
The access point supports an Ethernet uplink port (PoE-In) and a PoE out port (PoE-Out). The access
point 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).
The access point PoE-Out 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 Ethernet MAC addresses are printed on a label on the bottom of the access point under
the LEDs.
Tip
Caution
The access point senses the Ethernet and power signals and automatically switches internal
circuitry to match the cable connections.
To provide inline PoE, you must use the 1550 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 Option
The factory-orderable cable option provides a cable modem and Power-over-Cable (POC) capabilities
for the access point for high-speed data transfer and Internet access. When the cable option is selected
and installed, the access point uses its F-type cable connector to receive both data and power. Data is
passed between wireless clients on the mesh network to the cable company network via the internal
cable modem of the access point. 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.
22
Fiber Option
Warning

The 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 mesh
(non-root) access point (hereafter called a MAP), which is the default role of all access points. When
the access point has a fiber or 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 and 5-GHz band. Client access on 5-GHz is called universal client access.
23
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 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 as shown in Figure 10. 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. Control And Provisioning of Wireless Access Points (CAPWAP) control traffic is also
transferred over this bridged link.

(5.8 Ghz)
Point-to-Point Bridging
The 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 11. To support Ethernet bridging, you must enable
bridging on the controller for each access point. By default this capability is turned-off for all access
points.
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.

Point-to-Multipoint Bridging
The 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.

Point-to-Multipoint Mesh Network
The 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 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 data rate available for backhaul.
Figure 13 illustrates a typical mesh configuration using access points.

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 is the recommended operation. Figure 14 illustrates a typical Layer-3
wireless network configuration containing access points and a controller.

7 Preparing the Access Point
The 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
Wireless Mesh Access Points, Design and Deployment Guide, Release 7.0. 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.
27
Site Surveys
Cisco 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/b/g/n operates in an
unlicensed spectrum, 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 at the time of deployment.
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.
Tip
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 (if more than one antenna is being offered)?
• Do you have access to both of the mesh site locations?
• Do you have the proper permits, if required?
• Are you following the proper safety procedures and practices?
• 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 Environment
The radios on outdoor units (bridges) have higher transmit power levels than radios on indoor units
(access points). When you test radios in a link, you must avoid exceeding the maximum receive input
level of the receiver. At levels higher than the normal the operating range and packet error rate (PER)
performance of the receiver is degraded. At even higher levels, the receiver can be permanently
damaged.
28
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.
• Reduce the configured transmit power to the minimum level.
• 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 antenna gain + rx ant gain - [attenuation due to antenna spacing] < max rx
input level
Where:
txpwr = Radio transmit power level
tx gain = transmitter antenna gain
rx gain = receiver antenna gain
For a conducted test bed, the following equation describes the relationships among transmit power,
antenna gain, and receiver sensitivity:
txpwr - [attenuation due to coaxial RF Attenuator components] < max rx input level
(0 dbm)
Caution
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.
29
Before You Begin
Warning
Read the installation instructions before connecting the system to the power source.
Statement 1004
Before 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 10, Figure 2 on page 11, and
Figure 6 on page 14).
• Verify that the switch you are using to connect the controller is configured properly.
Note
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 Point
Warning
Do 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 364
The access point is deployed on Layer 3 networks. Layer 3 is 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 list
Verifying the Wireless LAN Controller Mode
Follow these steps to verify that the wireless LAN controller mode is set to Layer 3:
30
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

and click Apply.
Step 5
Save any changes you made.
Step 6
From the menu bar, click MONITOR to return to the Monitor Summary page.
Verifying the Wireless LAN Controller Software Version
On 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 Address
Use 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 List
The wireless LAN controller maintains an access point authorization MAC address list and responds
to discovery requests from access points on that list. To add the access point MAC address (or MAC
addresses) to the Wireless LAN controller filter list, follow these steps:
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.
31
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.
Note
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 Association
To 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 Notes
Using a DHCP Server in a Layer 3 Mesh Network
To 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.
32
Configuring DHCP Option 43
You 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_example09186a0080871

following URL:
http://www.cisco.com/en/US/docs/wireless/technology/controller/deployment/guide/dep.html#wp106
8287
Note
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
DHCP Vendor Class Identifier (VCI) string (DHCP Option 60) of the access point. The VCI strings for
Cisco access points capable of operating in lightweight mode are listed in Table 1:

For the VCI string, use the value from Table 1. The quotation marks must be included.
35
Step 4
Add the option 43 line using the following syntax:
option 43 hex hex string
The hex string is assembled by concatenating the TLV values shown below:
Type + Length + Value
Type is always f1(hex). Length is the number of controller management IP addresses times 4
in hex. Value is the IP address of the controller listed sequentially in hex.
For example, suppose that there are two controllers with management interface IP addresses,
10.126.126.2 and 10.127.127.2. The type is f1(hex). The length is 2 * 4 = 8 = 08 (hex). The
IP addresses translate to 0a7e7e02 and 0a7f7f02. Assembling the string then yields
f1080a7e7e020a7f7f02. The resulting Cisco IOS command added to the DHCP scope is listed
below:
option 43 hex f1080a7e7e020a7f7f02

Guidelines for Using the Access Point
You should keep these guidelines in mind when you use the access point:
• The access points can only communicate with controllers and cannot operate independently in
standalone mode.
• 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 CAPWAP 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 CAPWAP 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 CAPWAP
controller (CISCO-CAPWAP-CONTROLLER.) 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 LEDs
Four LEDs, located between the PoE-In and PoE-Out connectors, monitor the status of the access point
power, uplinks, and radios. Figure 16 identifies and describes the LED functions. Table 2 provides
additional LED signal information.

1. If all LEDs off, the access point has no power.
2. When the access point power supply is initially turned on, all LEDs are amber.
Note
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 address
IP 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 MAC
address to the filter list of the controller. When the misconfigured access point appears in the Summary
page of the controller, 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.
Verifying the Controller MAC Filter List
Prior to activating your access point, you must ensure that the access point MAC address has been
added to the controller MAC Filter list and that Mac Filter List is enabled. To view the MAC addresses
added to the controller MAC filter list and ensure the MAC filter list is enabled, you can use the
controller CLI or the controller GUI.
Controller CLI
Use the show macfilter summary controller CLI command to view the MAC addresses added to the
controller filter list.
Controller GUI
Log into your controller web interface (HTTPS) using a web browser and click SECURITY > AAA >
MAC Filtering to view the MAC addresses added to the controller filter list. Then click Wireless >
Mesh to ensure the MAC filter list is enabled.
