contact with power lines, or through earth currents. The Cisco Aironet AIR-ACC245LA-N Lightning Arrestor limits the amplitude and duration of disturbing interference voltages and improves the over voltage resistance of in-line equipment, systems, and components. A lightning arrestor installed according to these mounting instructions balances the voltage potential, thus preventing inductive interference to parallel signal lines within the protected system.
Cisco recommends that you bulkhead mount the lightning arrestor so it can be installed as a wall-feed through on the wall of the protected space.
The importance of obtaining a good ground and bonding connection cannot be overstressed. Consider these points when grounding the lightning arrestor:

Connect the lightning arrestor components directly to the grounding point.
The contact points of the ground connection must be clean and free of dust and moisture.
Tighten threaded contacts to the torque specified by the manufacturer.

Installation Notes

This lightning arrestor is designed to be installed between the antenna cable that is attached to an outdoor antenna and the Cisco Aironet wireless device. You can install the lightning arrestor either indoors or outdoors. It can be connected directly to a wireless device having an external N connector. It can also be mounted inline or as a feed-through. Feed-through installations require 5/8 in. (16 mm) hole to accommodate the lightning arrestor.
Note This lightning arrestor is part of a lightning arrestor kit. The kit contains a lightning arrestor and a
grounding lug.
Note When you install the lightning arrestor, follow the regulations or best practices applicable to lightning
protection installation in your local area.

Installing the Lightning Arrestor Outdoors

If you install the lightning arrestor outdoors, use the supplied ground lug and a heavy wire (#6 solid copper) to connect it to a good earth ground, such as a ground rod. The connection should be as short as possible.

Grounding the Access Point

Cable for the Lightning Arrestor

Coaxial cable loses efficiency as the frequency increases, resulting in signal loss. The cable should be kept as short as possible because cable length also determines the amount of signal loss (the longer the run, the greater the loss).
Cisco recommends a high-quality, low-loss cable for use with the lightning arrestor.
Grounding the Access Point
The access point must be grounded before connecting power.

Statement 1001
Statement 366
The 1532 access point supports these power sources:
DC power – 24- 57 VDC
Power-over-Ethernet (PoE)
The 1532 access point can be powered via the PoE input from an in-line power injector or a suitably powered switch port. Depending on the configuration and regulatory domain, the required power for full operation is UPoE. For the 1532E, 802.3at power is sufficient for all regulatory domains and full 2x2 MIMO operation on both 2.4 and 5 GHz radios. Either the AIR-PWRINJ4= or the AIR-PWRINJ1500-2= power injector can be used.
For the 1532I, UPoE powered switch port or the AIR-PWRINJ1500-2= power injector is required for full operation of the 3x3 MIMO on the 2.4 GHz radio in the regulatory domains that allow for high 2.4 GHz transmit power (Regulatory domains -A, -D, -F, -K, -N, -Q, -T, -Z). If the 1532I is powered by a PoE+ (802.3at power) switch port or the AIR-PWRINJ4= power injector, then the access point will automatically disable one of the 2.4 GHz transmitters and the radio will operate in 2x3 MIMO mode.

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.

Guidelines for Using the Access Points

Guidelines for Using the Access Points
You should keep these guidelines in mind when you use the access points:
The access point only supports Layer 3 CAPWAP communications with the controllers.
In Layer 3 operation, the access point and the controller can be on the same or different subnets. The access point communicates with the controller using standard IP packets. A Layer 3 access point on a different subnet than the controller requires a DHCP server on the access point subnet and a route to the controller. The route to the controller must have destination UDP ports 12222 and 12223 open for CAPWAP communications. The route to the primary, secondary, and tertiary controllers must allow IP packet fragments.
Before deploying your access points, ensure that the following has been done:
Your controllers are connected to switch ports that are configured as trunk ports.
Your access points are connected to switch ports that are configured as untagged access ports.
A DHCP server is reachable by your access points and has been configured with Option 43. Option 43 provides the IP addresses of the management interfaces of your controllers. Typically, a DHCP server can be configured on a Cisco switch.
Optionally, a DNS server can be configured to enable CISCO-CAPWAP-CONTROLLER. Use local domain to resolve to the IP address of the management interface of your controller.
Chapter 3 Troubleshooting
Your controllers are configured and reachable by the access points.
Your controllers are configured with the access point MAC addresses and the MAC filter list is enabled.
Your switch must forward DHCP requests.
After the access points are associated to the controller, you should change the bridge group name
(BGN) from the default value. With the default BGN, the mesh access points (MAPs) can potentially try to connect with other mesh networks and slow down the convergence of the network.

Important Notes

Convergence Delays

During deployment, the access points can experience convergence delays due to various causes. The following list identifies some operating conditions that can cause convergence delays:
A root access point (RAP) attempts to connect to a controller using any of the wired ports (cable,
fiber-optic, PoE-in). If the wired ports are operational, the RAP can potentially spend several minutes on each port prior to connecting to a controller.
If a RAP is unable to connect to a controller over the wired ports, it attempts to connect using the
wireless network. This results in additional delays when multiple potential wireless paths are available.
If a MAP is unable to connect to a RAP using a wireless connection, it then attempts to connect using
any available wired port. The access point can potentially spend several minutes for each connection method, before attempting the wireless network again.

Chapter 3 Troubleshooting

Bridge Loop

The access point supports packet bridging between wired and wireless network connections. The same network must never be connected to multiple wired ports on an access point or on two bridged access points. A bridge loop causes network routing problems.

The controller DHCP server only assigns IP addresses to lightweight access points and wireless clients associated to an access point. It does not assign an IP address to other devices, including Ethernet bridging clients on the mesh access points.

MAP Data Traffic

If the signal on the access point backhaul channel has a high signal-to-noise ratio, it is possible for a MAP to connect to the controller, via parent node, but not be able to pass data traffic, such as pinging the access point. This can occur because the default data rate for backhaul control packets is set to 6 Mb/s, and the backhaul data rate set to auto by the user.

Controller MAC Filter List

Controller MAC Filter List
Before activating your access point, you must ensure that the access point MAC address has been added to the controller MAC filter list and that Mac Filter List is enabled.
Note The access point MAC address and barcode is located on the bottom of the unit. When two MAC
addresses are shown, use the top MAC address.
To view the MAC addresses added to the controller MAC filter list, you can use the controller CLI or the controller GUI:
Controller CLI—Use the show macfilter summary controller CLI command to view the MAC
addresses added to the controller filter list.
Controller GUI—Log into your controller web interface using a web browser, and choose
SECURITY > AAA > MAC Filtering to view the MAC addresses added to the controller filter list.

Using DHCP Option 43

You can use DHCP Option 43 to provide a list of controller IP addresses to the access points, enabling the access point to find and join a controller. Refer to the product documentation for your DHCP server for instructions on configuring DHCP Option 43. For additional information, refer to the “Configuring
DHCP Option 43” section on page F-1.

Changing the 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 different BGNs and 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.
After the access points are deployed and associated to the controller, the BGN should be changed from the default value to prevent the MAPs from attempting to associate to other mesh networks.
The BGN should be configured very carefully on a live network. You should always start with the most distant access point (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 controller GUI, follow these steps:
Changing the Bridge Group Name
Step 1 Log into your controller using a web browser. Step 2 Click Wireless. When access points associates to the controller, the access point name appears in the AP
Name list.
Step 3 Click on an access point name. Step 4 Find the Mesh Information section, 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.

Configuring Option 43 for 1000, 1500, and 1530 Series Access Points

Configuring Option 43 for 1000, 1500, and 1530 Series Access Points
To configure DHCP Option 43 for Cisco 1000, 1500, and 1530 series access points in the embedded Cisco IOS DHCP server, follow these steps:
Step 1 Enter configuration mode at the Cisco IOS command line interface (CLI). Step 2 Create the DHCP pool, including the necessary parameters such as default router and name server. These
commands are used to create a DHCP pool:
ip dhcp pool pool name network IP Network Netmask default-router Default router dns-server DNS Server
Where: pool name is the name of the DHCP pool, such as AP1000 IP Network is the network IP address where the controller resides, such as 10.0.15.1 Netmask is the subnet mask, such as 255.255.255.0 Default router is the IP address of the default router, such as 10.0.0.1 DNS Server is the IP address of the DNS server, such as 10.0.10.2
Step 3 Add the Option 60 line for access point using the following syntax:
option 60 ascii VCI string
For the VCI string, use the value from Table F-1. The quotation marks must be included.
Step 4 Add the Option 43 line using the following syntax:
option 43 ascii Comma Separated IP Address List
For example, if you are configuring Option 43 for Cisco 1000, 1500, or 1500 series access points using the controller IP addresses 10.126.126.2 and 10.127.127.2, add the following line to the DHCP pool in the Cisco IOS CLI:
option 43 ascii “10.126.126.2,10.127.127.2”
The quotation marks must be included.

Configuring Option 43 for 1100, 1130, 1200, 1240, 1250, 1300, 1520, and 1530 Series Access Points
To configure DHCP Option 43 for Cisco Aironet 1100, 1130, 1200, 1240, 1250, 1300, 1520, and 1530 series access points in the embedded Cisco IOS DHCP server, follow these steps:
Step 1 Enter configuration mode at the Cisco IOS CLI. Step 2 Create the DHCP pool, including the necessary parameters such as default router and name server. The
commands used to create a DHCP pool are as follows:
ip dhcp pool pool name network IP Network Netmask default-router Default router dns-server DNS Server
Where: pool name is the name of the DHCP pool, such as AP1530 IP Network is the network IP address where the controller resides, such as 10.0.15.1 Netmask is the subnet mask, such as 255.255.255.0 Default router is the IP address of the default router, such as 10.0.0.1 DNS Server is the IP address of the DNS server, such as 10.0.10.2
Step 3 Add the Option 60 line using the following syntax:
option 60 ascii VCI string
For the VCI string, use the value from Table F- 1. The quotation marks must be included.
Step 4 Add the Option 43 line using the following syntax:
option 43 hex hex string
The hex string is assembled by concatenating the TLV values shown below:
Type + Length + Va lu e
Type is always f1(hex). Length is the number of controller management IP addresses times 4 in hex. Va l ue
is the IP address of the controller listed sequentially in hex.
For example, suppose that there are two controllers with management interface IP addresses,
10.126.126.2 and 10.127.127.2. The type is f1(hex). The length is 2 * 4 = 8 = 08 (hex). The IP addresses translate to 0a7e7e02 and 0a7f7f02. Assembling the string then yields f1080a7e7e020a7f7f02. The resulting Cisco IOS command added to the DHCP scope is listed below:
option 43 hex f1080a7e7e020a7f7f02
