Cisco Aironet 1570 Series Outdoor Access Point Hardware Installation Guide

OL-32138-01

Overview

The Cisco Aironet 1570 Series Outdoor Access Point (hereafter called the access point or AP) is a

wireless outdoor access point which is designed for use in a variety of network configurations. The

access point supports wireless client access, point-to-point bridging, point-to-multipoint bridging, and

point-to-multipoint mesh wireless connectivity.

About the Access Point

The Cisco Aironet 1570 Series Outdoor Access Point (hereafter called the access point or AP) is a high

performance outdoor access point designed for service in outdoor and mesh networks.

All versions of the access point have simultaneous dual-band radio consisting of an 802.11ac Wave 1

4x4:3 5 GHz radio and 4x4:3 802.11n 2.4 GHz radio. The access point versions which have a cable

modem, support up to 16x8 channel bonding.

The 1570 series access points have both internal and external antenna versions.

The internal antenna versions (AIR-AP1572IC versions) are optimized for service provider applications

using cable modem or fiber for data backhaul, rely on power-over-cable as the primary power source,

and provide GPS capability as an option.

The external antenna versions (AIR-AP1572E versions) have four dual band capable external antennas

ports. These versions support power over Ethernet input (AIR-AP1572EAC version only), power over

Ethernet output supporting up to 802.3at devices, internal AC or power over cable power supply options.

The access point can be configured, monitored, and operated through a Cisco wireless LAN controller

(hereafter called a controller) as described in the Cisco Wireless LAN Controller Configuration Guide.

The controllers use a browser-based management system, a command-line interface (CLI), or the Cisco

Prime Infrastructure (PI) network management system to manage the controller and the associated

access points. The access point supports hardware-based advanced encryption standard (AES)

encryption between wireless nodes to provide end-to-end security. The access point can also be deployed

in an autonomous mode and be configured via the CLI.

Power Sources

Warning

Connect the unit only to DC power source that complies with the safety extra-low voltage (SELV)

requirements in IEC 60950 based safety standards.

Statement 1033

Warning

To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord.

Statement 1023

Caution Power injectors must be used indoors only. Do not place a power injector in an unprotected outdoor

environment because water could get into the power injector and cause a short circuit and possible fire.

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).

Depending on the version of the access point, you may have the following power options available in

your access point:

•Power-over-cable (PoC) - The only source for internal antenna versions (AIR-AP1572I versions)

•AC

•DC

•UPOE (or AIR-PWRINJ1500-2 power injector)

The external antenna versions (AIR-AP1572E versions) support power over Ethernet input (on the AC

version only), power over Ethernet output supporting up to 802.3at devices, internal AC or power over

cable power supply options.

If multiple power sources are available, the access point will select the power source which is higher

on the following prioritization list. If a power source is removed, access point will automatically switch

to the next available power source, as per this list:

1. Power-over-cable or AC (whichever is available on your AP)

2. External DC input

3. PoE (available in AC powered versions of AP)

Power-over-Cable

All versions of AIR-AP1572I and some versions of AIR-AP1572E are equipped with a

power-over-cable (PoC) power supply. The power supply can accept quasi-AC signals in the 40 to 90

V RMS range.

Versions of the AP that have a PoC power supply, also have a shunt/fuse interface providing direct

in-line access to the PoC AC signal. The AP comes with a shunt in the shunt/fuse location. By removing

the shunt or fuse, field technicians can immediately remove power to the AP for service and repairs,

and then restore power by re-installing the shunt or fuse. You can install a fuse in the shunt/fuse

location to limit the maximum sustained current supplied to the AP to prevent damage to the AP or to

the cable plant. Fuses of various amperage are available, and so you can select the appropriate fuse

rating depending on the configuration and operating voltage.

AC powered versions of AIR-AP1572E can be powered by UPOE compliant power sourcing

equipment.

In addition to being powered by UPOE sources, the access point can also be powered by the

AIR-PWRINJ1500-2 power injector.

The access point also supports an Ethernet uplink port (PoE-In). 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 power from the power injector or a suitably powered switch port.

Tip The access point senses the Ethernet and power signals and automatically switches internal circuitry to

match the cable connections.

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

Chapter 1 Overview

Network Deployment Examples

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 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.

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 (see Figure 1-1). 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.

Figure 1-1 Access Point Backhaul Example

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 1-2. 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.

Network Deployment Examples

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 1-2 Access Point Point-to-Point Bridging Example

The access points can also support point-to-point bridging under autonomous mode. In this autonomous

mode, the bridging can be done on the 2.4 or 5 GHz radio, but not both. In this mode, one access point

is designated as the root and the other end is designated as the non-root bridge.

Figure 1-3 Access Point Point-to-Point Bridging in Autonomous Mode

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. Figure 1-4 illustrates an example

of access point-to-multipoint bridging.

Chapter 1 Overview

Network Deployment Examples

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.

Statement 1046.

Warning

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.:NFPA 70, National Electrical Code, Article 810, Canada: Canadian Electrical Code,

Section 54).

Statement 1052

Caution Before connecting or disconnecting a power cord, you must remove power from the power cord using a

suitable service disconnect.

For safety and to achieve a good installation, please read and follow these safety precautions:

•Select your installation site with safety, as well as performance in mind. Remember: electric power

lines and phone lines look alike. For safety, assume that any overhead line can kill.

•Call your electric power company. Tell them your plans, and ask them to come look at your proposed

installation.

•Plan your installation carefully and completely before you begin. Successful raising of a mast or

tower is largely a matter of coordination. Each person should be assigned to a specific task and

should know what to do and when to do it. One person should be in charge of the operation to issue

instructions and watch for signs of trouble.

•When installing the access point and antennas, remember:

–

Do not use a metal ladder.

–

Do not work on a wet or windy day.

–

Do dress properly—shoes with rubber soles and heels, rubber gloves, long sleeved shirt or

Chapter 2 Installing the Access Point

Avoiding Damage to Radios in a Testing Environment

•If any part of the antenna system should come in contact with a power line, do not touch it or try to

remove it yourself. Call your local power company. They will remove it safely.

If an accident should occur, call for qualified emergency help immediately.

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 maximum

receive input level for the receiver. At levels above the normal 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 are less if

conditions are not non-line-of-sight.

•Reduce the configured transmit power to the minimum level.

•Use directional antennas, and keep them away from each other.

•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 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 components] < max rx input level

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 that PER performance is not degraded.

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:

•For information on planning and initially configuring your Cisco Mesh network, refer to the Cisco

Wireless Access Points, Design and Deployment Guide, Release 7.3.

Cisco Aironet 1570 Series Outdoor Access Point Hardware Installation Guide

OL-32138-01

Chapter 2 Installing the Access Point

Installation Guidelines

•Review the FCC guidelines for installing and operating outdoor wireless LAN devices at

http://www.cisco.com/en/US/partner/prod/collateral/routers/ps272/data_sheet_c78-647116_ps114

51_Products_Data_Sheet.html.

•Perform a site survey before beginning the installation.

•Install the access point in an area where structures, trees, or hills do not obstruct radio signals to and

from the access point.

•The access points can be installed at any height, but best throughput is achieved when all the access

points are mounted at the same height. We recommend installing the access points no higher than

40 feet to allow support for wireless clients on the ground.

Note To calculate path loss and to determine how far apart to install access points, consult an RF planning

expert.

Site Surveys

Every network application is a unique installation. Before installing multiple access points, you should

perform a site survey to determine the optimum use of networking components and to maximize range,

coverage, and network performance.

Site surveys 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.

Consider the following operating and environmental conditions when performing a site survey:

•Data rates—Sensitivity and range are inversely proportional to data bit rates. The maximum radio

range is achieved at the lowest workable data rate. A decrease in receiver sensitivity occurs as the

radio data increases.

•Antenna type and placement—Proper antenna configuration is a critical factor in maximizing radio

range. As a general rule, range increases in proportion to antenna height. However, do not place the

antenna higher than necessary, because the extra height also increases potential interference from

other unlicensed radio systems and decreases the wireless coverage from the ground.

•Physical environment—Clear or open areas provide better radio range than closed or filled areas.

•Obstructions—Physical obstructions such as buildings, trees, or hills can hinder performance of

wireless devices. Avoid locating the devices in a location where there is an obstruction between the

sending and receiving antennas.

•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 tools and equipment to complete your survey.

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.

•Ensure that a DHCP server with Option 43 configured is reachable by your access points, or

manually configure the controller information in the access point (for additional information, refer

to the “Configuring DHCP Option 43” section on page F-1).

•Become familiar with the access point installation components (see the “Becoming Familiar with

Access Point Installation Components” section on page 2-12).

All versions of the 1570 series AP can be mounted to a strand. Two strand mount kits are available. One

version of the strand mount kit (SMK) is for mounting the AP directly to the strand when there is no

cable bundle. The other version is for mounting the AP to the strand in the presence of a 1.75 inch cable

strand and is approximately 2.25 inches from the top of the AP to the center of the cable strand.

Pole Mount Kits (PMKs)

All versions of the 1570 series AP can be mounted to either a pole or wall using a pole mount kit (PMK).

One PMK is designed specifically for the 1570I series and another PMK is designed specifically for the

1570E series.

The 1570I PMK allows the AP to be mounted in a horizontal orientation with antennas downward when

attached to a horizontal pole, vertical pole, or wall. The 1570E PMK allows the AP to be mounted

vertically when attached to a horizontal pole, vertical pole, or wall. Arbitrary off angle poles are not

supported. Both PMKs can be mounted to poles in diameter from 2 to 16 inches. Both PMKs maintain

a low profile with approximately 1 inch clearance between the pole/wall and the AP.

Pedestal Mount Kits

The 1570I series AP has a pedestal mount kit that allows it to be installed into a Channell 1420 pedestal

housing. The 1570E has a pedestal mount allowing it to be installed into a Channell 1212 pedestal

housing.

Access Point Mounting Orientation

When mounting an access point on a horizontal or vertical surface, you must ensure that the access

point is oriented with the LED indicators pointing down. This positioning allows LEDs to be visible

to someone on the ground below the access point.

You must also ensure the access point is mounted in such a way as to ensure that all antenna ports and

the console port are accessible for future use.

Note Omnidirectional antennas are vertically polarized and should be mounted vertically.

Non-Cisco Antennas

Cisco does not support any third-party antennas. RF connectivity and compliance of third party antennas

is the customer’s responsibility. Cisco does not recommend any third-party antennas, and Cisco

Technical Assistance Center will not be able to provide any support for third-party antennas. Cisco’s

FCC Part 15 compliance is only guaranteed with Cisco antennas or antennas that are of the same design

and gain as Cisco antennas.

Safety Precautions when Installing Antennas

Warning

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, as they may cause serious injury or death. For proper

installation and grounding of the antenna, please refer to national and local codes (e.g. U.S.: NFPA 70,

National Electrical Code, Article 810, Canada: Canadian Electrical Code, Section 54).

Statement 280

1. Before you install an antenna, contact your Cisco account representative to explain which mounting

method to use for the size and type of antenna that you are about to install.

2. Select your installation site with safety, as well as performance, in mind. Remember that electric

power lines and phone lines look alike. For your safety, assume that any overhead line can kill you.

3. Contact your electric power company. Tell them your plans and ask them to come look at your

proposed installation.

4. Plan your installation carefully and completely before you begin. Each person involved in an

installation should be assigned to a specific task and should know what to do and when to do it. One

person should be in charge of the operation to issue instructions and watch for signs of trouble.

5. When installing your antenna, follow these guidelines:

–

Do not use a metal ladder.

–

Do not work on a wet or windy day.

–

Do dress properly—wear shoes with rubber soles and heels, rubber gloves, and a long-sleeved

shirt or jacket.

6. If the assembly starts to drop, move away from it and let it fall. Because the antenna, mast, cable,

and metal guy wires are all excellent conductors of electrical current, even the slightest touch of any

of these parts to a power line completes an electrical path through the antenna and the installer.

7. If any part of the antenna system should come in contact with a power line, do not touch it or try to

remove it yourself. Call your local power company to have it removed safely.

8. If an accident should occur with the power lines, call for qualified emergency help immediately.

Antenna Configurations

Integrated Antenna Option

The AP1572I uses an 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 antenna’s visual footprint, and greatly reducing the

possibility of snagging the antenna on the cable bundle, the RF cable, or test cables. Each of thee three

Installing a Lightning Arrestor

Overvoltage transients can be created through lightning static discharges, switch processes, direct

contact with power lines, or through earth currents. The Cisco Aironet AIR-ACC245LA-N Lightning

Arrestor limits the amplitude and duration of disturbing interference voltages and improves the over

voltage resistance of in-line equipment, systems, and components. A lightning arrestor installed

according to these mounting instructions balances the voltage potential, thus preventing inductive

interference to parallel signal lines within the protected system.

2-26

Cisco Aironet 1570 Series Outdoor Access Point Hardware Installation Guide

OL-32138-01

Chapter 2 Installing the Access Point

Installing Antennas

Installation Considerations

Cisco recommends that you bulkhead mount the lightning arrestor so it can be installed as a wall-feed

through on the wall of the protected space.

The importance of obtaining a good ground and bonding connection cannot be overstressed. Consider

these points when grounding the lightning arrestor:

•Connect the lightning arrestor components directly to the grounding point.

•The contact points of the ground connection must be clean and free of dust and moisture.

•Tighten threaded contacts to the torque specified by the manufacturer.

Installation Notes

This lightning arrestor is designed to be installed between the antenna cable that is attached to an outdoor

antenna and the Cisco Aironet wireless device. You can install the lightning arrestor either indoors or

outdoors. It can be connected directly to a wireless device having an external N connector. It can also be

mounted inline or as a feed-through. Feed-through installations require 5/8 in. (16 mm) hole to

accommodate the lightning arrestor.

Note This lightning arrestor is part of a lightning arrestor kit. The kit contains a lightning arrestor and a

grounding lug.

Note When you install the lightning arrestor, follow the regulations or best practices applicable to lightning

protection installation in your local area.

Installing the Lightning Arrestor Outdoors

If you install the lightning arrestor outdoors, use the supplied ground lug and a heavy wire (#6 solid

copper) to connect it to a good earth ground, such as a ground rod. The connection should be as short as

possible.

Chapter 2 Installing the Access Point

Grounding the Access Point

Figure 2-17 Lightning Arrestor Details

Cable for the Lightning Arrestor

Coaxial cable loses efficiency as the frequency increases, resulting in signal loss. The cable should be

kept as short as possible because cable length also determines the amount of signal loss (the longer the

run, the greater the loss).

Cisco recommends a high-quality, low-loss cable for use with the lightning arrestor.

Grounding the Access Point

The access point must be grounded before connecting power.

Warning

This 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 366

Warning

Installation of the equipment must comply with local and national electrical codes.

Statement 1074

In all outdoor installations and when powering the access point with AC power, you must follow these

instructions to properly ground the case:

Statement 366

Warning

Do not work on the system or connect or disconnect cables during periods of lightning activity.

Statement 1001

The 1572 access point supports these power sources:

•DC power – 24- 57 VDC

•Power-over-Ethernet (PoE)

The 1572 access point can be powered via the PoE input from an in-line power injector or a suitably

powered switch port. Depending on the configuration and regulatory domain, the required power for full

operation is UPoE. For the 1572E, 802.3at power is sufficient for all regulatory domains and full 2x2

MIMO operation on both 2.4 and 5 GHz radios. Either the AIR-PWRINJ4= or the AIR-PWRINJ1500-2=

power injector can be used.

For the 1572I, UPoE powered switch port or the AIR-PWRINJ1500-2= power injector is required for

full operation of the 3x3 MIMO on the 2.4 GHz radio in the regulatory domains that allow for high 2.4

GHz transmit power (Regulatory domains -A, -D, -F, -K, -N, -Q, -T, -Z). If the 1572I is powered by a

PoE+ (802.3at power) switch port or the AIR-PWRINJ4= power injector, then the access point will

automatically disable one of the 2.4 GHz transmitters and the radio will operate in 2x3 MIMO mode.

Chapter 2 Installing the Access Point

Powering the Access Point

Step 3 When using the streetlight power tap adapter (AIR-PWR-ST-LT-R3P=), ensure that the access point is

mounted within 3 feet (1 m) of the outdoor light control.

Step 4 Ensure that a 6-AWG ground wire is attached to the access point (see Figure 2-34) and connected to the

streetlight pole (for instructions see Grounding the Access Point, page 2-27).

Note Deployment of the AP as shown in the streetlight deployment in Figure 2-34 requires an

alternate AP mounting kit. See Mounting the Access Point section for more information.

Step 5 Ensure that the streetlight power tap adapter, which uses a 3-pronged LC-10 twist-lock adapter, is placed

between the outdoor light control and its fixture (refer to Figure 2-34). The LC-10 twist-lock adapter is

designed to be used with LC-10 listed outdoor light controls operating at 100 to 480 VAC, 50 to 60 Hz.

Step 6 Disconnect the outdoor light control from its fixture.

Step 7 Verify that the voltage available at the fixture is between 100 and 480 VAC, 50 to 60 Hz.

Step 8 Turn off power to the fixture at the designated circuits.

Caution When installing the streetlight power tap adapter to the access point AC power connector, always

connect the access point end of the cable FIRST. When removing the streetlight power tap adapter,

always disconnect the access point end of the cable LAST.

Note Ensure that your antennas are connected to the access point before you apply power to the access point.

Step 9 Connect the streetlight power tap adapter to the access point AC/DC power adapter. See Wiring the

Streetlight Power Tap Adapter to the AC/DC Power Adapter.

Step 10 Plug the streetlight power tap adapter into the outdoor light control fixture, as shown in Figure 2-34.

Step 11 Plug the outdoor light control into the streetlight power tap adapter.

Step 12 Ensure that the antennas are connected to the access point before you apply power to the access point.

Step 13 Turn on the power to the outdoor light control fixture at the designated circuits.

Wiring the Streetlight Power Tap Adapter to the AC/DC Power Adapter

The AC plugs of the streetlight power tap adapter (AIR-PWR-ST-LT-R3P=) and the AC/DC power

adapter (AIR-PWRADPT-1570=) are incompatible. Hence, you need to connect the cables to wire them

together, using the illustration in Figure 2-24. Ensure that you follow local electrical and safety codes

when making and protecting this connection.

Warning

Ensure that all electrical power is turned off before making this connection.

Warning

Follow all local wiring and electrical codes when making this connection. Note that the spliced

cables may need to be housed in an approved junction box.

Chapter 2 Installing the Access Point

What to Do Next

When you power up a MAP that is not connected to a wired Ethernet, fiber-optic, or cable network to

the controller, the access point uses the Cisco Adaptive Wireless Path Protocol (AWPP) to bind to

another mesh access point (MAP) with the best path to a root access point (RAP) connected to the wired

network to a controller. The access point sends a discovery request when powered up. If you have

configured the access point in the controller correctly, the controller sends back a discovery response to

the access point. When that happens, the access point sends out a join request to the controller, and the

controller responds with a join confirmation response. Then the access point establishes a Control And

Provisioning of Wireless Access Points (CAPWAP) connection to the controller and gets the shared

secret configured on the controller.

Refer to the Cisco Wireless LAN Controller Configuration Guide for more information on configuring,

monitoring, and operating your access points.

Chapter 3 Troubleshooting

Guidelines for Using the Access Points

You should keep these guidelines in mind when you use the access points:

•The access point only 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. 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 route to the primary, secondary, and tertiary controllers must

allow IP packet fragments.

•Before deploying your access points, ensure that the following has been done:

–

Your controllers are connected to switch ports that are configured as trunk ports.

–

Your access points are connected to switch ports that are configured as untagged access ports.

–

A DHCP server is reachable by your access points and has been configured with Option 43.

Option 43 provides the IP addresses of the management interfaces of your controllers. Typically,

a DHCP server can be configured on a Cisco switch.

–

Optionally, a DNS server can be configured to enable CISCO-CAPWAP-CONTROLLER. Use

local domain to resolve to the IP address of the management interface of your controller.

–

Your controllers are configured and reachable by the access points.

–

Your controllers are configured with the access point MAC addresses and the MAC filter list is

enabled.

–

Your switch must forward DHCP requests.

•After the access points are associated to the controller, you should change the bridge group name

(BGN) from the default value. With the default BGN, the mesh access points (MAPs) can potentially

try to connect with other mesh networks and slow down the convergence of the network.

Important Notes

Convergence Delays

During deployment, the access points can experience convergence delays due to various causes. The

following list identifies some operating conditions that can cause convergence delays:

•A root access point (RAP) attempts to connect to a controller using any of the wired ports (cable,

fiber-optic, PoE-in). If the wired ports are operational, the RAP can potentially spend several

minutes on each port prior to connecting to a controller.

•If a RAP is unable to connect to a controller over the wired ports, it attempts to connect using the

wireless network. This results in additional delays when multiple potential wireless paths are

available.

•If a MAP is unable to connect to a RAP using a wireless connection, it then attempts to connect using

any available wired port. The access point can potentially spend several minutes for each connection

method, before attempting the wireless network again.

Chapter 3 Troubleshooting

Controller MAC Filter List

Bridge Loop

The access point supports packet bridging between wired and wireless network connections. The same

network must never be connected to multiple wired ports on an access point or on two bridged access

points. A bridge loop causes network routing problems.

Controller DHCP Server

The controller DHCP server only assigns IP addresses to lightweight access points and wireless clients

associated to an access point. It does not assign an IP address to other devices, including Ethernet

bridging clients on the mesh access points.

MAP Data Traffic

If the signal on the access point backhaul channel has a high signal-to-noise ratio, it is possible for a

MAP to connect to the controller, via parent node, but not be able to pass data traffic, such as pinging

the access point. This can occur because the default data rate for backhaul control packets is set to 6

Mb/s, and the backhaul data rate set to auto by the user.

Controller MAC Filter List

Before 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.

Note The access point MAC address and barcode is located on the bottom of the unit. When two MAC

addresses are shown, use the top MAC address.

To view the MAC addresses added to the controller MAC filter list, 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 using a web browser, and choose

SECURITY > AAA > MAC Filtering to view the MAC addresses added to the controller filter list.

Using DHCP Option 43

You can use DHCP Option 43 to provide a list of controller IP addresses to the access points, enabling

the access point to find and join a controller. Refer to the product documentation for your DHCP server

for instructions on configuring DHCP Option 43. For additional information, refer to the “Configuring

DHCP Option 43” section on page F-1.

Monitoring the Access Point LEDs

If your access point is not working properly, look at the LEDs on the bottom of the unit. You can use

them to quickly assess the status of the unit.

Note It is expected that there will be small variations in LED color intensity and hue from unit to unit. This is

within the normal range of the LED manufacturer specifications and is not a defect.

Chapter 3 Troubleshooting

Changing the Bridge Group Name

The bridge group name (BGN) controls the association of the access points to a RAP. BGNs can be used

to logically group the radios to avoid different networks on the same channel from communicating with

each other. This setting is also useful if you have more than one RAP in your network in the same area.

If you have two RAPs in your network in the same area (for more capacity), we recommend that you

configure the two RAPs with different BGNs and on different channels.

The BGN is a string of ten characters maximum. A factory-set bridge group name (NULL VALUE) is

assigned during manufacturing. It is not visible to you, but allows new access point radios to join a

network of new access points. The BGN can be reconfigured from the Controller CLI and GUI. After

configuring the BGN, the access point reboots.

After the access points are deployed and associated to the controller, the BGN should be changed from

the default value to prevent the MAPs from attempting to associate to other mesh networks.

The BGN should be configured very carefully on a live network. You should always start with the most

distant access point (last node) from the RAP and move towards the RAP. If you start configuring the

BGN in a different location, then the access points beyond this point (farther away) are dropped, as they

have a different BGN.

To configure the BGN for the access points using the controller GUI, follow these steps:

Step 1 Log into your controller using a web browser.

Step 2 Click Wireless. When access points associates to the controller, the access point name appears in the AP

Name list.

Step 3 Click on an access point name.

Step 4 Find the Mesh Information section, and enter the new BGN in the Bridge Group Name field.

Step 5 Click Apply.

Step 6 Repeat Steps 2 through 5 for each access point.

Step 7 Log out from your controller, and close your web browser.

Appendix F Configuring DHCP Option 43

Overview

This section contains a DHCP Option 43 configuration example on a DHCP server for use with Cisco

Aironet Access Points. For other DHCP server implementations, consult DHCP server product

documentation for configuring DHCP Option 43. In Option 43, 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, 1500, 1532 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 DHCP Vendor Class

Identifier (VCI) string (DHCP Option 60). The VCI strings for Cisco access points that can operate in

lightweight mode are listed in Table F-1.

The following is the format of the TLV block for 1100, 1130, 1200, 1240, 1250, 1300, 1520, and 1532

access points:

•Type: 0xf1 (decimal 241)

Points

To configure DHCP Option 43 for Cisco 1000, 1500, and 1570 series access points in the embedded

Cisco IOS DHCP server, follow these steps:

Step 1 Enter configuration mode at the Cisco IOS command line interface (CLI).

Step 2 Create the DHCP pool, including the necessary parameters such as default router and name server. These

commands are used to create a DHCP pool:

ip dhcp pool pool name

network IP Network Netmask

default-router Default router

dns-server DNS Server

Where:

pool name is the name of the DHCP pool, such as AP1000

IP Network is the network IP address where the controller resides, such as 10.0.15.1

Netmask is the subnet mask, such as 255.255.255.0

Default router is the IP address of the default router, such as 10.0.0.1

DNS Server is the IP address of the DNS server, such as 10.0.10.2

Step 3 Add the Option 60 line for access point using the following syntax:

option 60 ascii “VCI string”

For the VCI string, use the value from Table F-1. The quotation marks must be included.

Step 4 Add the Option 43 line using the following syntax:

option 43 ascii “Comma Separated IP Address List”

For example, if you are configuring Option 43 for Cisco 1000, 1500, or 1500 series access points using

the controller IP addresses 10.126.126.2 and 10.127.127.2, add the following line to the DHCP pool in

the Cisco IOS CLI:

option 43 ascii “10.126.126.2,10.127.127.2”

The quotation marks must be included.

and 1570 Series Access Points

To configure DHCP Option 43 for Cisco Aironet 1100, 1130, 1200, 1240, 1250, 1300, 1520, and 1570

series access points in the embedded Cisco IOS DHCP server, follow these steps:

Step 1 Enter configuration mode at the Cisco IOS CLI.

Step 2 Create the DHCP pool, including the necessary parameters such as default router and name server. The

commands used to create a DHCP pool are as follows:

ip dhcp pool pool name

network IP Network Netmask

default-router Default router

dns-server DNS Server

Where:

pool name is the name of the DHCP pool, such as AP1570

IP Network is the network IP address where the controller resides, such as 10.0.15.1

Netmask is the subnet mask, such as 255.255.255.0

Default router is the IP address of the default router, such as 10.0.0.1

DNS Server is the IP address of the DNS server, such as 10.0.10.2

Step 3 Add the Option 60 line using the following syntax:

option 60 ascii “VCI string”

For the VCI string, use the value from Table F-1. The quotation marks must be included.

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 + Va l u e

Type is always f1(hex). Length is the number of controller management IP addresses times 4 in hex. Va l u e

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:

unicast packet A single data message (packet) sent to a specific IP address.

UPoE Cisco Universal Power Over Ethernet (UPOE) extends IEEE PoE+ standard by

doubling the power per port to 60W over a single standard Ethernet Cable. It

allows the consolidation of 60 watts power on a single Ethernet (CAT5E or

higher) cable, or in short 60W per access switch port.

WDS Wireless Domain Services. An access point providing WDS on your wireless

LAN maintains a cache of credentials for CCKM-capable client devices on your

wireless LAN. When a CCKM-capable client roams from one access point to

another, the WDS access point forwards the client's credentials to the new access

point with the multicast key. Only two packets pass between the client and the

new access point, greatly shortening the reassociation time.

WEP Wired Equivalent Privacy. An optional security mechanism defined within the

802.11 standard designed to make the link integrity of wireless devices equal to

that of a cable.

WPA Wi-Fi Protected Access is a standards-based, interoperable security enhancement

that strongly increases the level of data protection and access control for existing

and future wireless LAN systems. It is derived from and will be

forward-compatible with the upcoming IEEE 802.11i standard. WPA leverages

TKIP (Temporal Key Integrity Protocol) for data protection and 802.1X for

authenticated key management.
