2-6

Cisco Aironet 1550 Series Outdoor Mesh Access Point Hardware Installation Guide

OL-24247-01

Chapter 2 Installing the Access Point

• 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:

–

• Use a rope to lift the access point. If the assembly starts to drop, get away from it and let it fall.

• 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

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 jacket.

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

OL-24247-01

Cisco Aironet 1550 Series Outdoor Mesh Access Point Hardware Installation Guide

2-7

Installation Guidelines

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 Mesh Access Points, Design and Deployment Guide, Release 7.0.

Chapter 2 Installing the Access Point

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

Site Surveys

• 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.

expert.

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.

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.

OL-24247-01

Chapter 2 Installing the Access Point

• 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.

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 2-9).

Installation Guidelines

Becoming Familiar with Access Point Installation Components

The access point is designed to be installed in an outdoor environment, such as the exterior roof overhang of a tall building or a streetlight pole. Carefully review the following figures to become familiar with the system components, connectors, indicators, cables, system interconnection, and grounding:

• Components in a typical access point installation (see Figure 2-1)

• Pole mount installation (see Figure 2-2)

• Cable strand mount installation (see Figure 2-3

• Streetlight power tap installation (see Figure 2-4)

Note The illustrations in this document show all available connections for the access point. Unused

connections are capped with a connector plug to ensure the watertight integrity of the access point. liquid-tight adapters are provided for connector openings, which can be installed before or after deploying the access point.

Note The 1552 access point was designed with consideration for resistance to effects of lightning effects on

the access point electronics. The 1552 access point employs lightning arrestor circuitry on the Ethernet and power ports. On the input Ethernet port, Gas Discharge Tubes (GDT) are used for the Power Entry Module (PEM) to mitigate lightning effect. On the AC power, GDTs are also used along with fuses to mitigate high-current condition. For the DC power, a fuse is used to mitigate high current condition.

While not a common practice, the user may want to consider using lightning protection at the antenna ports for added protection. To meet EN/IEC60950-22 (Clause 4.2) requirements, the installer must ensure that additional protection is provided external to this equipment to reduce transient surges from Overvoltage IV to Overvoltage Category II at the AC power input of the access point. The over-voltage and fault-current protection components used to achieve this protection must comply with the IEC 61643

(CAT5e or better) cable

series of standards. To meet CAN/CSA-C22.2 No. 60950-22-07/UL60950-22 requirements, the installer may use alternative components to provide this additional protection. Those components may comply with ANSI/IEEE C62.11, CSA Certification Notice No. 516, CSA C22.2 No. 1, or UL 1449. Suitability of the components for the application must be determined for the intended installation. (For example, some devices are suitable for installation on the load side of the service entrance only, and some are suitable for use with cord-connected equipment only.)

Adding the Access Point MAC Addresses to the Controller Filter List

Before installing your access points, configure your controller by adding the MAC addresses of the access points to the filter list. MAC address filtering is enabled by default. This enables the controller to respond to the listed access points. To add a MAC filter entry on the controller, follow these steps:

Step 1 Log into your controller using a web browser.

Step 2 Choose SECURITY > MAC Filtering > New.

Step 3 Enter the MAC address of the access point to the MAC Filter list; for example, 00:0B:91:21:3A:C7.

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

are shown, use the top MAC address.

Installation Guidelines

Step 5 Enter a description (32 characters maximum) of the access point in the Description field; for example,

Fisher_Street_00.0B.91.21.3A.C7 shows the location and MAC address of the access point.

Step 6 Choose an interface from the Interface Name pop-up menu, and click Apply.

Step 7 Repeat Steps 2 to 6 to add other access points to the list.

Step 8 Log out of your controller, and close your web browser.

Configuring a RAP

The access point defaults to the mesh access point (MAP) radio role. One or more of your access points must be reconfigured as a root access point (RAP). The RAPs connect to a wired Ethernet link through a switch to the controller. The MAPs use their wireless backhaul interface to connect to a RAP to reach the controller.

To configure a RAP on the controller GUI, follow these steps:

Step 1 Log into your controller using a web browser.

Step 2 Click Wireless. When your access point associates to the controller, the name of the access point appears

in the AP Name list.

Step 3 Double-click your access point name.

Chapter 2 Installing the Access Point

Step 4 Find Mesh Information, and choose Root AP by clicking the drop-down arrow in the AP Role field.

Step 5 Click Apply.

Step 6 Repeat Steps 2 through 5 for each RAP.

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

Configuring a 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 the same BGN, but 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.

The BGN should be configured very carefully on a live network. You should always start from the farthest node (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.

Step 4 Position the two bolts on the access point into the quick mount notches on each side of the mounting

bracket (see Figure 2-2). Ensure that the hinged door is facing out.

Step 5 Screw a M8 x16 bolt (with flat and lock washers) into the second bolt hole on each side of the access

point.

Step 6 Ensure that the front of the access point is vertical, and tighten the four bolts to 13 to 15 ft lbs

(17.6 to 20.3 Nm).

Step 7 When using the Cisco Aironet Dual-Band Omnidirectional Antennas, connect them to the access point

as shown in Figure 2-2. Hand-tighten the antennas to the access point.

Step 8 Continue with the “Grounding the Access Point” section on page 2-34 and the “Powering the Access

Chapter 2 Installing the Access Point

Mounting the Access Point on a Pole

When installing an access point on a vertical pole, mast, or a streetlight pole, you should use the optional Cisco pole mount kit. The kit supports metal, wood, or fiberglass poles from 2 to 16 inches in diameter.

Assembling the Pole Clamp Bracket and the Mounting Bracket

When installing an access point on a pole, mast, or a streetlight, you should use the optional Cisco pole mount kit. The kit supports metal, wood, or fiberglass poles from 2 to 16 inches in diameter.

The pole mount kit contains several parts that you must assemble prior to mounting on a pole. First you need to assemble two strap brackets on the pole clamp bracket that are positioned for the pole diameter you are using to mount the access point. Figure 2-8 illustrates the pole diameter indicators and bolt holes on the pole clamp bracket.
