Installing the Access Point
Avoiding Damage to Radios in a Testing Environment
•
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
jacket.
•
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
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:
•
Note
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.
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 +
Where:
txpwr =
tx gain
rx gain
tx gain + rx gain - [attenuation due to antenna spacing] < max rx input level
Radio transmit power level
= transmitter antenna gain
= receiver antenna gain

Chapter 2
Installing the Access Point
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:
Note
•
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.
•
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.
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.
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.

Installation Guidelines
•
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).
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:
Note
•
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)
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

Installation Guidelines
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.)
Warning
Installation of the equipment must comply with local and national electrical codes. Statement 1074

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
Step 4
The access point MAC address is located on the bottom of the unit. When two MAC addresses
are shown, use the top MAC address.
Select a WLAN ID or Any WLAN from the WLAN ID pop-up menu.

Chapter 2
Installing the Access Point
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.
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.

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 (see Figure 2-2, Figure 2-3, and Figure 2-4). This
positioning allows the LEDs to be visible to someone on the ground below the access point.
You must also ensure the access point is mounted with the hinged access cover facing out.
Note
Omnidirectional antennas are vertically polarized and should be mounted vertically with the antennas
facing down.
Mounting the Access Point on a Wall
The optional pole mount kit contains a mounting bracket for wall mounting. You can use the mounting
bracket as a template to mark the positions of the mounting holes for your installation. You then install
the mounting plate, and attach the access point when you are ready. Table 2-1 lists the material that you
will need to provide in addition to the pole mount kit.

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.

Installing the Access Point
Installing the Access Point
Pole Mounting
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 1522 access point uses the 5-GHz radio for the Mesh backhaul and connections. The 2.4-GHz radio
is used for 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 2-2).

Installing the Access Point in Hazardous Locations
The access point hazardous location option complies with safety standards for Class I, Division 2, Zone
2 hazardous locations where ignitable concentrations of flammable gases, vapors, or liquids are not
likely to exist under normal operation conditions.
When you select the hazardous location option as part of the ordering process, Cisco configures the
system to contain the new components. Two conduit adapters and assembly instructions placed in the
shipping box provide information and assembly procedures. The hazardous location option configures
the access point as follows:
•
The battery pack is removed because battery construction does not meet hazardous location
requirements.
•
Do not install the battery (AIR-1520-BATT-6AH=) in the AIR-CAP1552H-x-K9 access point.
•
The AC power connections are moved to the inside of the access point by installing an AC entry
board containing a terminal block. To comply with hazardous location requirements, AC power must
be installed through rigid metal conduit to the terminal block.
Caution
Do not use any form of sealant or gasket material when joining conduit components.
Caution
The electrical rating for hazardous location installations has a lower voltage rating (100-240
VAC, 50/60 Hz, 1A) than a non-hazardous location installation (100-480 VAC).
Note
To provide a proper seal, threaded conduit must be used to route the power and data cabling to

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.
