Installing a Lightning Arrestor
Overvoltage transients can be created through lightning static discharges, switch processes, direct
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.
Installation Considerations
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:

Installing Antennas
•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.

Chapter 2 Installing the Access Point
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.
Warning This equipment must be externally grounded using a customer-supplied ground wire before power is
applied. Contact the appropriate electrical inspection authority or an electrician if you are uncertain
that suitable grounding is available. Statement 366
Warning Installation of the equipment must comply with local and national electrical codes. Statement 1074
In all outdoor installations and when powering the access point with AC power, you must follow these
instructions to properly ground the case:
Step 1 If using insulated 6-AWG copper ground wire, strip the insulation as required for the grounding lug.
Step 2 Use the appropriate crimping tool to crimp the bare 6-AWG copper ground wire to the supplied
grounding lug.
Note The grounding lug and hardware used must comply with local and national electrical codes.
Step 3 Open the anti-corrosion sealant (supplied), and apply a liberal amount over the metal surface where the
ground strap screw holes are located (see Figure 1-5).
Step 4 Connect the grounding lug to the access point grounding screw holes (see Figure 1-5) using the supplied
two Phillips head screws (M4 x10 mm) with lock washers. Tighten the grounding screw to
22 to 24 lb-in (2.49 to 2.71 Nm).
Step 5 If necessary, strip the other end of the ground wire and connect it to a reliable earth ground, such as a
grounding rod or an appropriate grounding point on a metal streetlight pole that is grounded (see
Figure 2-3).

that suitable grounding is available. Statement 366
Warning Do not work on the system or connect or disconnect cables during periods of lightning activity.
Statement 1001
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.
Table 2-7 AP 1530 Power Matrix
Caution Do not place the power injector in an unprotected outdoor environment because water could get into the
power injector and cause a short circuit and possible fire.

The 1530 Series Access Points support the following power injectors:
•AIR-PWRINJ1500-2= — 100-240 VAC input, indoor use only
•AIR-PWRINJ4= — 100-240 VAC input, indoor use only
The power injector provides (AIR-PWRINJ1500-2=) 56 VDC to the access point over the Ethernet cable
and supports a total end-to-end Ethernet cable length of 100 m (328 ft) from the switch to the access
point.
When your access point is powered by an optional power injector, follow these steps to complete the
installation:
Step 1 Before applying PoE to the access point, ensure that the access point is grounded (see the “Grounding
the Access Point” section on page 2-40).
Step 2 Review Figure 2-2 to identify the components needed for the installation.
Note The 1500 power injector can only be used in an indoor environment, therefore, the cable from
the injector must travel from the protected location to the outside mounted access point.
Step 3 Connect a CAT5e or better Ethernet cable from your wired LAN network to the power injector.
Warning To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord. Statement 1023
Note The installer is responsible for ensuring that powering the access point from this type of power
injector is allowed by local and/or national safety and telecommunications equipment standards.
Tip To forward bridge traffic, add a switch between the power injector and controller. Refer to the
Cisco Wireless Mesh Access Points, Design and Deployment Guide, Release 7.0 for more
information.

What to Do Next
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.

Chapter 3 Troubleshooting
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.
– 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.

Controller MAC Filter List
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.
Controller DHCP Server
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
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.
