Statement 1052
|
Caution using a suitable service disconnect.
For additional important safety instructions for AC power cords, refer to the AC Power Cords for Cisco Aironet 1520 Series Outdoor Mesh Access Points document that shipped with your AC power cords.
For safety and to achieve a good installation, please read and follow these safety precautions:
1. 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.
2. Call your electric power company. Tell them your plans, and ask them to come look at your proposed installation.
3. 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.
4. When installing the access point and antennas, 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, rubber gloves, long sleeved shirt or jacket.
5. Use a rope to lift the access point. If the assembly starts to drop, get away from it and let it fall.
6. 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 receiver's maximum receive input level. 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
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 Deployment Guide: Cisco Mesh Networking Solution.
•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 recommends 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 a radio frequency (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.
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.
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 .
•Become familiar with the access point installation components (see the hardware installation guide).
Becoming Familiar with Access Point Installation Components
The access point is designed to be installed in an indoor or outdoor environment, such as an interior wall or ceiling or 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 1)
•Pole mount installation (see Figure 2)
•Strand mount installation (see Figure 3)
•Streetlight power tap installation (see Figure 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 access point's watertight integrity. liquid tight adapters are provided for connector openings, which can be installed before or after deploying the access point. The illustrations do not show antenna port 5, which is reserved for future use.

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. Follow these steps to add a MAC filter entry on the controller:
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.
Step 4 Select a WLAN ID or Any WLAN from the WLAN ID pop-up menu.
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 MAP radio role. One or more of your access points must be reconfigured as a 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.
Follow these steps to configure a RAP on the controller GUI:
Step 1 Log into your controller using a web browser.
Step 2 Click Wireless. When your access point associates to the controller, your access point's name appears in the AP Name list.
Step 3 Double-click your access point's name.
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.
To configure the BGN for the access points using the 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's name appears in the AP Name list.
Step 3 Double-click on an access point's name.
Step 4 Find Mesh Information, 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.
Mounting the Access Point
This section provides instructions for installing your access points. Personnel installing the access point must understand wireless access points and bridging techniques and grounding methods.
Caution All mounting methods on any wall surface is subject to the acceptance of local jurisdiction.
Installation Options
There are two optional installation kits:
•Pole mount kit—used for pole, wall, or streetlight installations

The access point can be installed where power is available, without the need for a wired LAN connection. The access point uses intelligent wireless routing that is based on the Adaptive Wireless Path Protocol (AWPP). AWPP enables a remote access point to dynamically optimize the best route to the wired LAN network using another access point.
The LAP1522 model uses the 5-GHz radio for the Mesh backhaul Mesh connections. The 2.4-GHz radio is used for local wireless client access. The LAP1521 model uses the 2.4-GHz radio for both Mesh backhaul and local wireless client access.
To mount your access point on a vertical pole or streetlight pole, you need to install two metal bands around the pole to support the access point. This process requires extra tools and material not provided in the pole mount kit (see Table 3).

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 to bind to another MAP with the best path to a 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 an LWAPP 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. The following lists some of the configuration settings you might want to reconfigure:
•Selecting a backhaul channel when using the 4.9 MHz band
•Reconfiguring the bridge group name
