FCC Safety Compliance Statement

The FCC with its action in ET Docket 96-8 has adopted a safety standard for human exposure to radio frequency (RF) electromagnetic energy emitted by FCC certified equipment. When used with approved Cisco Aironet antennas, Cisco Aironet products meet the uncontrolled environmental limits found in OET-65 and ANSI C95.1, 1991. Proper installation of this radio according to the instructions found in this manual will result in user exposure that is substantially below the FCC recommended limits.

General Safety Guidelines

Do not touch or move antenna(s) while the unit is transmitting or receiving.

Do not hold any component containing a radio so that the antenna is very close to or touching any exposed parts of the body, especially the face or eyes, while transmitting.

The use of wireless devices in hazardous locations is limited to the constraints posed by the local codes, the national codes, and the safety directors of such environments.

Basic Installation Guidelines

Because the access point is a radio device, it is susceptible to interference that can reduce throughput and range. Follow these basic guidelines to ensure the best possible performance:

Ensure that a site survey has been performed to determine the optimum placement of access points.

For lightweight access points, check the latest release notes to ensure that your controller software version supports the access points to be installed. You can find the controller release notes by selecting your controller under Wireless LAN Controllers at this URL:

http://www.cisco.com/en/US/products/hw/wireless/tsd_products_support_category_home.html

Ensure that access points are not mounted closer than 20 cm (7.9 in) from the body of all persons.

Do not mount the access point within 3 ft (91.4 cm) of metal obstructions.

Install the access point away from microwave ovens. Microwave ovens operate on the same frequency as the access point and can cause signal interference.

Do not mount the access point outside of buildings.

Do not mount the access points on building perimeter walls unless outside coverage is desired.

Controller Discovery Process for Lightweight Access Points

The lightweight access point supports these controller discovery processes:

DHCP server discovery—Uses DHCP Option 43 to provide controller IP addresses to the access points. Cisco switches support a DHCP server option. For additional information, refer to the "Configuring DHCP Option 43 for Lightweight Access Points" section on page G-1.

DNS server discovery—The access point uses the name CISCO-LWAPP-CONTROLLER.<local domain> to discover the controller IP addresses from a DNS server. Where <local domain> is the access point domain name.

Locally stored controller IP addresses—If the access point was previously associated to a controller, the IP addresses of the primary, secondary, and tertiary controllers are stored in the access point non-volitile memory. The process of storing controller IP addresses in access points for later deployment is called priming the access point. For additional information, refer to the "Priming Lightweight Access Points Prior to Deployment" section on page F-1.

You can also manually configure controller information using CLI commands on new (out-of-the-box) access points that are not connected to a controller. For additional information refer to the "Manually Configuring Controller Information Using the Access Point CLI" section on page 7-5.

Cisco recommends that you configure a DHCP server with Option 43 to provide the controller IP addresses to your access points. Cisco switches provide a DHCP server option that is typically used for this purpose.

Deploying the Access Points on the Wireless Network

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

Ensure that a site survey has been preformed.

Ensure that your network infrastructure devices are operational and properly configured.

For lightweight access points, perform these tasks:

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.

To deploy your access points, follow these steps:


Step 1 Obtain the access point location map created during your building site survey.

Step 2 Review the access point locations and identify the specific mounting methods required for each access point location.

Step 3 For each access point perform these steps:

a. For lightweight access points, record the access point MAC address on the access point location map. When you have completed the lightweight access point deployment, return the access point MAC addresses and the access point locations on the access point location maps or floor plans to your network planner or manager. The network operators can use the MAC address and location information to create maps for precise wireless system management.

b. Mount the access point at the indicated destination using the specified mounting method. For specific mounting instructions, see these sections:

Attaching the access point to the mounting plate (see the "Attaching the Access Point to the Mounting Bracket" section on page 3-8).

Horizontal or vertical surface, such as a ceiling or wall (see the "Mounting on a Horizontal or Vertical Surface" section on page 3-3).

Below a suspended ceiling (see the "Mounting Below a Suspended Ceiling" section on page 3-4).

Above a suspended ceiling (see the "Mounting Above a Suspended Ceiling" section on page 3-5).

c. Optionally secure the access point using a padlock or security cable (see the "Securing the Access Point to the Mounting Bracket" section on page 3-8).

d. Connect the access point cables (Ethernet, optional power, optional antennas). For instructions see the "Connecting the Ethernet and Power Cables" section.

e. On power up, verify that the access point is associated to a controller and operating normally. For additional information, refer to the "Checking the Top Panel LEDs" section on page 6-2.

Step 4 For lightweight access points, after your access points are deployed, ensure that your controller is not configured as a master controller. A master controller should only be used for configuring access points and not in a working network.


Connecting the 2.4-GHz Antennas

The access point supports a single antenna or dual diversity antennas. Two RP-TNC antenna connectors are provided on the back of the unit for the 2.4-GHz radio.


Note RP-TNC antenna connectors are used for both the 2.4-GHz and 5-GHz radios. Do not connect Cisco 5-GHz antennas with blue labels or blue dots to the 2.4-GHz antenna connectors (refer to Figure 2-1 for connector locations).


To attach your antenna or antenna cable to the access point, follow these steps:


Step 1 Attach an antenna or antenna cable to the 2.4-GHz Right/Primary (RP-TNC) antenna connector on the back of the access point and hand tighten. If you are using two antennas for diversity coverage, attach the second antenna or antenna cable to the 2.4-GHz Left (RP-TNC) antenna connector.

Step 2 If you are using a Cisco Aironet 2 dBi antenna, orient the antenna depending on how you intend to mount the access point.

On a table or desk, orient the antenna straight up.

On a vertical surface, such as a wall, orient the antenna straight up.

On a ceiling, orient the antenna straight down.

Step 3 If you are using another Cisco Aironet antenna, refer to the antenna mounting instructions that came with your antenna.


Connecting the 5-GHz External Antennas

The access point supports an RM22A radio module for use with a single antenna or dual diversity antennas. Two RP-TNC antenna connectors are provided on the back of the module for the 5-GHz radio.


Note RP-TNC antenna connectors are used for both the 2.4-GHz and 5-GHz radios. Only connect Cisco 5-GHz antennas with blue labels or blue dots to the 5-GHz antenna connectors (refer to Figure 2-3 for connector locations).


If you are using the RM22A radio module, follow these steps:


Step 1 Attach the Cisco Aironet 5-GHz antenna cable to the Right/Primary 5-GHz (RP-TNC) antenna connector on the back of the radio module and hand tighten. If you are using two antennas for diversity coverage, attach the second antenna cable to the Left 5-GHz (RP-TNC) antenna connector.


Note The Cisco Aironet antennas have a blue marker label or blue dot near the antenna connector and the radio module has a corresponding blue label near the 5-GHz antenna connectors.


Step 2 To mount your Cisco Aironet antenna, refer to the instructions that came with your antenna.


Connecting the Ethernet and Power Cables

The access point receives power through the Ethernet cable or an external power module. Figure 2-4 shows the power options for the access point.

Figure 2-4 Access Point Power Options

The access point power options are listed below:

A switch with inline power, such as a Cisco Catalyst 3500XL, 3550-24 PWR, 4000, or 6500 switch

A Cisco Aironet Power Injector (AIR-PWRINJ-FIB or AIR-PWRINJ3)

An inline power patch panel, such as the Cisco Catalyst Inline Power Patch Panel

A power module (Universal power supply)


Note Currently, the Catalyst 3550-24 PWR switch supports power for both the 2.4-GHz radio and the 5-GHz radio. Other switches and power patch panels might not provide enough power for the 5-GHz radio.



Note If you use in-line power, do not connect the power module to the access point. Using two power sources on the access point might cause the switch to shut down the port to which the access point is connected.


Connecting to an Ethernet Network with an Inline Power Source


Caution The Cisco Aironet Power Injectors are designed for use with Cisco Aironet access points only. Using the power injector with other Ethernet-ready devices can damage the equipment.


Caution Only the fiber-optic power injector (AIR-PWRINJ-FIB) has been tested to UL 2043 for operation in a building's environmental air space; no other power injectors or power modules have been tested to UL 2043 and they should not be placed in a building's environmental air space, such as above suspended ceilings.

Follow these steps to connect the access point to the Ethernet LAN when you have an inline power source:


Step 1 Connect the Ethernet cable to the RJ-45 Ethernet connector labeled Ethernet on the access point.

Step 2 Connect the other end of the Ethernet cable to one of the following:

A switch with inline power, such as a Cisco Catalyst 3500XL, 3550-24 PWR, 4000, or 6500 switch.

An inline power switch panel, such as a Cisco Catalyst Inline Power Patch Panel.

The end of a Cisco Aironet power injector labeled To AP/Bridge. Connect the other end labeled To Network to the 10/100 Ethernet LAN.



Note If you use a power supply or power injector to power the access point, you must use the power supply included with your access point and the Cisco Aironet Power Injector for the 1100 and 1200 series access points.


Connecting to an Ethernet Network with Local Power

Follow these steps to connect the access point to an Ethernet LAN when you are using a local power source:


Step 1 Connect the Ethernet cable to the RJ-45 Ethernet connector labeled Ethernet on the access point.

Step 2 Plug the other end of the Ethernet cable into an unpowered Ethernet port on your network.

Step 3 Connect the power module's output connector to the 48-VDC power port labeled 48VDC on the access point.

Step 4 Plug the other end of the power module into an approved 100- to 240-VAC outlet.
