Introduction

The Cisco Aironet 1300 Series Lightweight Outdoor Access Point (hereafter called an access point) is designed for indoor or outdoor installations, providing differing antenna gains as well as coverage patterns. These access points are part of the Cisco Integrated Wireless Network Solution and require no manual configuration before they are mounted. The access point is automatically configured by a Cisco Wireless LAN Controller (herafter called a controller) using the Lightweight Access Point Protocol (LWAPP).

Operating in the 2.4-GHz band (2.400 to 2.497 GHz), using the IEEE 802.11g standard, the access point delivers 1 to 54 Mbps data rates without the need for a license. Using a controller, you can configure the radio settings.

In the Cisco Centralized Wireless LAN architecture, access points operate in the lightweight mode (as opposed to autonomous mode). The access points associate to a controller. The controller manages the configuration, firmware, and control transactions such as 802.1x authentication. In addition, all wireless traffic is tunneled through the controller.

LWAPP is an Internet Engineering Task Force (IETF) draft protocol that defines the control messaging for setup and path authentication and run-time operations. LWAPP also defines the tunneling mechanism for data traffic.

In an LWAPP environment, a lightweight access point discovers a controller by using LWAPP discovery mechanisms and then sends it an LWAPP join request. The controller sends the access point an LWAPP join response allowing the access point to join the controller. When the access point is joined, the access point downloads its software if the versions on the access point and controller do not match. After an access point joins a controller, you can reassign it to any controller on your network.

LWAPP secures the control communication between the access point and controller by means of a secure key distribution, utilizing X.509 certificates on both the access point and controller.

The access point is available with an integrated antenna or with external antenna connectors. When using a access point with an integrated antenna, you must choose a mounting location with a clear path to the remote antenna and orient the access point so that the antenna is positioned for maximum signal strength. The mounting brackets in the optional installation kit has adjustment slots that facilitate the positioning process. When using a access point with an external antenna, mount the access point in a convenient location near the external antenna. Each external antenna has its own mounting instructions.

Note To meet regulatory restrictions, the external antenna access point and the external antenna must be

professionally installed. The network administration or other IT professional responsible for installing and configuring the unit is a suitable professional installer. Following installation, access to the unit should be password protected by the network administrator to maintain regulatory compliance.

System Requirements

The access point system consists of a weather-proof unit, a power injector, a grounding block, and optional external antennas. The access point and external antennas are typically mounted outdoors, the grounding block is installed at the building entrance, and the power injector and the power module are installed indoors. This document describes the access point mounting procedures only. For information about other components, see the “Related Documentation” section on page 38.

Each year hundreds of people are killed or injured when attempting to install an antenna. In many of these cases, the victim is aware of the danger of electrocution, but does not take adequate steps to avoid the hazard.

For your safety, and to help you properly install hardware, please read and follow these safety precautions. They may save your life!

1. If you are installing an antenna for the first time, for your own safety as well as others, seek

assistance from a person with skills and knowledge related to the construction and operation of electrical equipment and has received safety training on the hazards involved.

2. Keep safety as well as performance in mind when selecting your installation site Remember: electric

power lines and phone lines look alike. Always assume that overhead lines are very dangerous.

Statement 1033

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

installation. This is a reasonable request considering the danger.

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

tower is largely a matter of coordination. Assign each person a specific task, and ensure that they know what to do and when to do it. Put one person in charge of the operation to issue instructions and watch for signs of trouble.

5. When installing your antenna, remember:

a. Do not use a metal ladder.

b. Do not work on a wet or windy day.

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

6. If the assembly starts to fall, get away from it and let it fall. Remember, the antenna, mast, cable,

and metal guy wires are excellent conductors of electrical current and may touch power lines.

7. If any part of the antenna system comes in contact with a power line, don’t touch it or try to remove

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

If an accident occurs with the power lines, call for qualified emergency help immediately.

Deploying Lightweight Access Points on the Wireless Network

Prior to beginning the actual lightweight access point deployment, perform these tasks:

• 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 Cisco Aironet 1300 Series Outdoor Access Point/Bridge Hardware Installation Guide).

Choosing a Mounting Location

Choosing a good mounting location for the access point is important because it affects the reliability of the wireless link and maximum data rates it can support. The most important considerations are distance between wireless devices and clearance from obstacles. The mounting location can be a wall, ceiling, the top or side of a building, or on a tower providing a clear unobstructed line-of-sight to the wireless devices.

With the integrated antenna access point configuration, the location must allow the access point to be oriented in the proper direction.

With the external antenna access point configuration, the external antenna must be located within line-of-sight of the wireless devices. The access point can be located in a convenient location that minimizes the cable length to the antenna.

Note To meet regulatory restrictions, the external antenna access point and the external antenna must be

Signal Path Distance

In an environment without obstacles in the signal path, the maximum operating distance depends primarily on the type of antennas and the free space loss between the access point and wireless devices. Make sure your proposed mounting site is within range of the wireless devices.

Note When operating as an access point, the maximum communication distance is approximately 1 mile.

78-17634-01

Cisco Aironet 1300 Series Lightweight Outdoor Access Point Mounting Instructions

Choosing a Mounting Location

Antenna Polarization

The integrated antenna radiates and receives vertically polarized radio signals. Polarization helps reduce interference because the antenna tends to reject cross-polarized signals from other sources.

Note For the multi-point links, Cisco recommends that you use vertical polarization on all antennas; however,

on point-to-point links you can also use horizontal polarization on both ends of the link. To operate correctly, the antennas at each end of the wireless link should have the same polarization.

The following lightweight access point antenna is vertically polarized:

• 5.2-dBi omni-directional antennas

The following lightweight access point antennas can be vertically or horizontally polarized depending on their mounting orientation:

• 10-dBi a yagi antennas

• 9-dBi patch wall-mount antenna

Signal Path Clearance

A radio beam travels from the access point to another in a straight line. Therefore, the path between the antennas must be free of major obstacles. The effects of obstacles and terrain, both along and near the path, have a significant bearing on the propagation of radio signals and can cause both interference and signal cancellation.

When choosing a site, consider the effects of the following common obstacles:

• Trees and large plants

A tree directly in the path can totally block the signal. With clearance above the trees there are usually no secondary effects, but you should allow for future tree growth.

• Man-made obstacles

A large round container such as a gas storage reservoir or water tower that is partially in the path causes some blocking. These obstacles may also reflect some energy, which can interfere with other receivers. Square or rectangular objects in or near the path have rectangular surfaces that can block and diffract signals over and around them.

• Internal building obstacles

When mounting the access point in an indoor location, the signal can be block obstructions, such as walls, office cublicles, steel file cabinets, metal ducts, and metal shelving. These obstacles can also reflect some energy, which can interfere with radio receivers.

For tower installations, you may need to climb the tower to the proposed mounting location to verify a clear path to the other site. If trees are in the line of signal propagation, leave extra clearance above them for future growth into the signal path.

Physical Site Inspection

Perform a visual inspection of the site to ascertain and document the physical characteristics of the site and to ensure that all requirements are met for the proper installation and operation of the system.

Contact Information and Access Permissions

Make sure the following general requirements are met before beginning the installation:

• Validate customer-provided information, such as site contact names and telephone numbers.

• Examine the building (tenant) lease to verify or establish building roof or tower rights. If available,

use layout drawings to evaluate the feasibility of modifications or special permits that might be necessary.

• For a tower-mounted installation, find out if the owner, operator, or landlord requires a professional

or certified tower climber to do the work.

Physical Site

Make sure the following physical site requirements are met before beginning the installation:

• Identify the roof area, wall, or tower for mounting the access point.

Choosing a Mounting Location

Cable Routes

Caution To prevent damage to the access point or power injector, connect all coax cables from the power injector

• Determine the access area, such as a stairway or a ladder.

• Identify existing equipment installations and assess the condition of proposed towers or mounting

structures.

• Assess environmental conditions, such as temperature, ventilation, and humidity.

Make sure the following cable route requirements are met before beginning the installation:

• Identify cable routes, building entry points, and any special routing or support requirements

(conduits, bracing, cable trays, safety structures, and so on). Make sure the total cable length between the access point and the power injector is no greater than 100 meters.

• Identify necessary floor, roof, or wall penetrations and specify the locations.

• Document existing grounding system and connection requirements for new equipment.

• Refer to these electrical codes for your local regulations:

Cisco Aironet 1300 Series Lightweight Outdoor Access Point Mounting Instructions

Mounting the Access Point

Lightning Arrestor

In outdoor antenna installations, your antenna and access point can be damaged by surges that develop on the antenna and cable from close lightning strikes. You can use a lightning arrestor (such as AIR-ACC-3354) to help protect your access point system from static electricity and lightning-induced surges; however, an arrestor will not prevent damage from a direct lightning hit.

A lightning arrestor is a 50-ohm transmission line with a gas discharge tube positioned between the center conductor and ground. This gas discharge tube changes from an open circuit to a short circuit almost instantly (100 nanoseconds) in the presence of voltage and energy surges, providing a path to ground for the energy surge.

A lightning arrestor should be installed between your outdoor antenna and the access point. You should connect a 6 AWG copper wire from the arrestor to a good earth ground.

Document all the necessary tools, parts, brackets, hardware and accessories that are required for the installation and make sure you have them all before starting.

Window Mounting

When you are deploying a wireless access point link through a window, the window glass can introduce significant signal loss. Typical losses range from 5 to 15 dB per window, depending upon the type of glass. Deployment planning should take this extra loss into account conservatively when planning antenna gains and power settings. A thorough site survey is critical for deployments that require penetration through windows.

For additional information on a window mounting bracket, refer to the following URL:

http://www.terra-wave.com/shop/above-ceiling-tile-mounting-bracket-with-adjustable-height-p-665.ht ml

General Guidelines

Many types of window glass allow radio signals to pass through easily while some types greatly restrict radio signals. These are some general guidelines for operating through window glass:

• Avoid glass with metallic content or metallic coatings

• Avoid glass with conductive gas between the panes

• Avoid glass with embedded wire

• Select windows at roughly the same height at both ends

• Select windows with the least thickness

• Ensure that radio signal quality tests are conducted through the glass before finalizing the site

selection

Mounting Above a Suspended Ceiling

The access point can be mounted above a suspended ceiling in environmental air space using the wall or ceiling mounting bracket (refer to the “Wall or Ceiling Mounting Bracket” section on page 13).

Note The access point and power injector have adequate fire resistance and low smoke-producing

characteristics to make them suitable for operation in a building's environmental air space (such as above suspended ceilings) in accordance with Section 300-22(C) of the National Electrical Code (NEC).

Note When mounting the access point or power injector in a building's environmental air space, you must use

Mounting the Access Point

To mount the access point on a tower, follow these steps:

Step 1 Choose a mounting location on the tower for the access point. If you are using the integrated antenna,

the mounting location must provide a clear signal path to the remote access point. For more information, see “Choosing a Mounting Location” section on page 7.

Step 2 Find a suitable mounting support or install a mounting pole for the access point. The mounting bracket

accommodates poles from 1.25 to 2.75 inches (30.5 to 69.9 mm) in diameter; the supplied U bolts fit

1.25 to 1.75-inch poles only. You can find this type of hardware at http://www.rohnnet.com.

Step 3 Hoist the access point assembly to the mounting location. The mounting brackets have openings for

hoisting the unit.

Step 4 Attach the access point to the mounting pole using appropriate hardware (see Figure 6). For more

information, see the “Assembling the Mounting Hardware” section on page 26.

Step 5 Point the antenna as accurately as possible in the direction of the remote antenna. The integrated antenna

is correctly positioned when the flat face of the radome faces the remote antenna.

Statement 1024

Note Local code may require grounding of the tower mount.

Step 6 Find the building's grounding electrode system and then connect the access point ground lug to it using

to the Access Point” section on page 28. See Figure 11 for the ground lug location.

Routing the Cables for Lightning Protection

In areas where lightning strikes are common and when the access point is mounted high on the tower, ground the shields of the RG6 coaxial cables to the tower at regular intervals. This precaution helps protect the access point and power injector from lightning damage. The recommended spacing between grounds is 200 ft (60 m). In areas of especially high lightning risk, space the grounds even closer.

Cisco Aironet 1300 Series Lightweight Outdoor Access Point Mounting Instructions

Mounting the Access Point

Note Be sure to comply with the tower owner's policies and local codes. Drilling into tower structures,

damaging painted surfaces, or other alterations can affect the tower's long-term integrity.

To route and connect cables for lightning protection follow these steps:

Step 1 Mount grounding blocks to the tower at intervals of about 200 ft (60 m) along the cable route. Make sure

each grounding block makes good electrical (metal-to-metal) contact with the tower.

Step 2 Cut cable segments for each interval and preinstall F-connectors.

Step 3 Secure the cable segments along the route using UV-stabilized Ty-Wraps or equivalent fasteners.

Step 4 Connect all cable segments. For outdoor installations, use drip loops at each point to assure that water

runs away from the connectors.

Step 5 Proceed to the following procedure, starting from the lowest grounding block instead of from the access

point.

Routing the Cables Normally

To route and connect power injector cables normally, follow these steps:

Step 1 Unspool two 75-ohm cables the full length of the tower, laying them out straight without kinks. Do not

cut the cables until you know the total required length between the access point and grounding block.

Step 2 Install F-connectors on the cable ends before climbing the tower.

Step 3 Tie a rope near the end of the two cables, and secure it using black electrical tape. Make sure that the

connectors do not support any cable weight.

Step 4 From the tower, use the rope to pull the cables up from the ground, making sure that they pass along a

tower member where they can be securely fastened. Leave ample cable for a service loop at the access point.

Step 5 Secure the cables to the tower and along the route to the building grounding block using UV-stabilized

Ty-Wraps or equivalent fasteners.

Warning

Statement 1024

Caution To prevent damage to the access point or power injector, connect all coax cables from the

kit. For more information, see the “Applying Coax Seal Tape” section on page 24.

Mounting the access point on a tall mast makes antenna positioning difficult because you cannot view the access point LEDs or adjust the antenna vertically. If possible, use a mast short enough so that you can reach the access point from a step ladder or other support. Otherwise, you may need to take down the mast to adjust the antenna position.

Mounting the access point on a mast includes the following subtasks:

1. Preparing the mast

2. Mounting the access point

3. Routing mast cables

This warning applies to outdoor installations.

Warning

Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

Statement 1030

Preparing the Mast

To prepare the mast, follow these steps:

Step 1 Choose a mounting location for the mast. For more information, see the “Choosing a Mounting

Location” section on page 7.

Step 2 Find a solid mounting position on the building for the mast mounting bracket, such as a stud or main

building member on a roof or external wall. Use a stud finder, if necessary, to find wooden structural members.

Step 3 Find the mast-mounting hardware and guy wire.

Step 4 Find and install the guy line mounting points. A minimum of three, preferably four, guy lines should

hold the mast in position.

Step 5 Measure the length of the guy lines by attaching the lines to the mast at their mounting point and

unspooling them to the attachment points.

4. Raising the mast and connecting cables

Step 6 Raise the mast to its vertical position and temporarily secure all guy lines to their mounting points.

Step 7 Ensure that the mast is vertical using a level on two sides (90 degrees apart) of the pole. Adjust guy lines

as necessary and note their attachment points.

Routing Mast Cables

To route and connect cables, follow these steps:

Step 1 Unspool two 75-ohm cables the full length from the access point to the grounding block, laying them

out straight without kinks. Do not cut the cables until you know the total required length between access point and grounding block.

Step 2 Install F-connectors on the access point end of each cable and connect the cables to the access point. The

cables should slope downward from the access point connectors (when the mast is raised) so that moisture runs away from the access point during rainstorms. If necessary, form drip loops near the connector.

Step 3 Secure the cables to the mast using UV-stabilized Ty-Wraps or equivalent fasteners.

Step 4 Weather seal all coaxial connectors by wrapping them with the sealant tape provided with the installation

kit. For more information, see the “Applying Coax Seal Tape” section on page 24.

Raising the Mast and Connecting Cables

Mounting the Access Point

To raise the mast and connect cables, follow these steps:

Step 1 Tilt the mast assembly to the upright position, set the mast in its mounting base clamp, orient the antenna

in the direction of the remote antenna, and secure the guy wires.

Step 2 Tighten the mast clamp so the mast is secure but so that it can be rotated for final adjustments in

positioning.

Mounting the Access Point

Caution To prevent damage to the access point or power injector, connect all coax cables from the

power injector to the access point and connect the power jack to the power injector before applying power.

Note The grounding block must be connected to the building's grounding system by # 14 AWG copper

wire or larger.

Step 5 Cut the cables to length, install F-connectors on the ends, and connect them to the grounding block.

Step 6 Weather seal all coaxial connectors by wrapping them with the sealant tape provided with the installation

kit. For more information, see the “Applying Coax Seal Tape” section on page 24.

Applying Coax Seal Tape

You must weather seal all coaxial connections using the Coax-Seal tape provided in the mounting kit. Coax connections that are not properly sealed permit moisture to enter the connection, which leads to performance degradation or link problems.

The following connectors must be weather sealed:

• F-connectors, located at the access point and each grounding block.

• R-TNC antenna connectors, when using the access point with an external antenna.

Note Do not use only plastic electrical tape on the connectors because it deteriorates during long-term

exposure to ultraviolet light and extreme weather.

To apply Coax Seal, follow these steps:

Step 1 Make sure that the coaxial cables, connectors, and the connector area are clean and dry.

Step 2 Peel the paper backing from a 10-inch length of Coax-Seal tape.

Step 3 Wrap each access point connector with the tape, starting at the coaxial cable, extending across the

connector body, and finishing close the access point or grounding block. Overlap each turn at least 50 percent so there is a double thickness over all areas (see Figure 8).

Note To simplify removal of the connector in the future, you can first wrap the connector with a good

grade of electrical tape before applying the Coax-Seal. You should tightly wrap the electrical tape and overlap each turn at least 25 percent for full coverage.

Warning

Note The Cisco Aironet Power Injector LR2T must be used with a DC power source.

Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

Statement 1030

Electrical Load-Dump Protection

In battery power systems, a load-dump occurs when the battery is disconnected from the charging system while supplying power, and the devices connected to the battery system must dissipate the very large energy transient that is produced. For example, this situation can occur if the battery cables are loose or in a service shop where a mechanic accidentally removes the battery cable while the engine is running.

In order to comply with the transportation vehicle load-dump requirements specified in SAE 1211 and SAE1455 standards, you must use an external load-dump protection device. This device must be connected to the power cable between your vehicle’s battery system and the power injector.

You must install an external load-dump protection device in all vehicle systems that can experience a load-dump and that are supplying +24 VDC (or above) to the power injector.

For more information on load-dump protection devices, refer to Appendix I of the Cisco Aironet 1300 Series Outdoor Access Point/Bridge Hardware Installation Guide.

DC Power Cable and Connector

When using a DC power source, you are responsible for providing the power cable, fuse, and power connector used for the power injector. The power injector requires an external power supply capable of supplying 13 W of power at a typical vehicle battery voltage: +12 VDC, +24 VDC, or +40 VDC. For the power cable, the positive voltage is connected to the center pin and the return is connected to the external barrel of the power plug.
