REVIEW DRAFT — CISCO CONFIDENTIAL
Welcome
Thank you for choosing the Cisco AP541N. The Cisco AP541N, part of the
Cisco Smart Business Communications System (SBCS), is a wireless
network communications device.
This guide is designed to familiarize you with the general layout of the
access point, how to deploy the device in your network, and access the
configuration interface. Your access point has more features or
functionality than what is described in this guide. For additional
configuration information, see the Cisco AP541N Administration Guide
available at www.cisco.com/go/TBD.

Before You Begin
Decide if you are going to configure the device by using a static IP address
or the IP address assigned by a network DHCP server.
NOTE It is expected that a static IP address to be assigned to the
access point is based on the network topology and known prior
to installation.
If while displaying the configuration window the IP address is
changed, either by a DHCP server or manually, you will loose
connectivity between the PC and the access point.
Also make sure that you have the following equipment and services:
•Tools for installing the hardware
•PC with Microsoft Internet Explorer (version 6 and higher), Firefox
(version 3 or higher), or Safari (for Mac).
•TBD
•TBD
•Need Eng to provide the information for this section.

Getting to Know the Cisco
AP541N
This section describes the exterior of the access point.
Front Panel LEDs
PWR—Lights green while the access point is powered on. Blinks during a
firmware upgrade.
PoE—Lights green when Power-over-Ethernet (PoE) is powering the
access point.
Diag—Lights red during the power-on-self-test (POST) or the system is
otherwise not ready.
Speed—The LAN LED light is off when the LAN port data speed is zero or
10 Mbps. Lights amber to indicate the LAN port data speed is 100 Mbps.
Lights green to indicate the LAN port data speed is 1000 Mbps.
LAN—Lights solid green when a link is established. Blinks green when the
port is passing traffic.
WLAN 2.4G—Lights solid green when a 2.4 GHz wireless network link is
established. Blinks green when the link is passing traffic. The light is off
when the 2.4 GHz radio is off.

WLAN 5.0G—Lights solid green when a 5.0 GHz wireless network link is
established. Blinks green when the link is passing traffic. The light is off
when the 5.0 GHz radio is off.
Back Panel Ports
Ethernet Port—The access point is equipped with an auto-sensing, Gigabit
Ethernet (802.3) port used for configuration and wired network
communications. Auto-sensing technology enables the port to
automatically detect the speed and duplex settings of the device
connected to it, and adjust its speed and duplex settings to match the
settings of the connected device. The Gigabit Ethernet port accepts an
RJ-45 connector and supports Power-over-Ethernet (PoE).
NOTE We recommend using Cat5e or better cable. Also, do not
exceed the maximum cabling distance of 328 feet (100
meters) per segment.
ANT01, ANT02, and ANT03—BNC connectors that accept the antennas
provided with the access point.

Installing the Cisco AP541N
The access point can be placed on a wall, a flat surface, a ceiling, or in a
ceiling plenum space. A ceiling mount kit is available for this device
(SKU#). Do not deploy the device in a location where any of the following
conditions exist:
High Ambient Temperature—The ambient temperature must not
exceed 104 degrees Fahrenheit (40C).
Reduced Air Flow—The air flow must be adequate to prevent
overheating.
Mechanical Overloading—The device should be level, stable, and
secure to avoid it sliding or shifting out of position.
Circuit Overloading—Adding the device to the power outlet or a PoE
port must not overload that circuit or PoE device.
NOTE We recommend using Cat5e or better cable. Also, do not
exceed the maximum cabling distance of 328 feet (100
meters).
To place the access point on a desktop, install the four rubber feet
(included) on the bottom of the access point. Place the device on a flat
surface.
To prepare the device, do the following:
STEP 1Attach the antennas to the RP-TNC connectors labeled ANT101,
ANT102, and ANT103. The antennas are all the same, so which
antenna is attached to what connector is of no consequence.
STEP 2Determine where you want to locate the access point. If you are
using AC power, make sure the location is within reach of an AC
power outlet.
STEP 3Keep enough ventilation space for the access point and check for
any environmental restrictions.

Wall Mounting
Before you begin, you need 2 wallboard screws (included) to mount the
access point. We recommend using screws with a minimum of 4mm width
at the head and a shaft diameter of at least 1.5mm.
WARNING Cisco is not responsible for damages incurred by insecure wall-
mounting.
To mount the access point to the wall:
STEP 1Determine where you want to mount the access point. Verify that
the surface is smooth, flat, dry, and sturdy.
STEP 2Drill two pilot holes into the surface 5.75 inches (146 mm) apart,
and with a minimum of 4.0 inches (101 mm) of clearance.
STEP 3Insert a screw into each hole, leaving a gap between the surface
and the base of the screw head of at least 0.1 inches (3 mm).
STEP 4Place the access point wall-mount slots over the screws and slide
the access point down until the screws fit snugly into the wall-
mount slots.

Flat Surface Installation
To prepare the device for placement the device on a flat surface, do the
following:
STEP 1Install the four rubber feet (included) on the bottom of the device.
STEP 2Place the access point on a desktop near an AC power source,
unless you are using PoE.

Connecting the Equipment
This section describes the process for connecting the device to power
and the network.
STEP 1Attach the power cord to the power connector and outlet (if used).
STEP 2Connect a network Ethernet cable to the access point Ethernet
port.
STEP 3Connect the other end of the Ethernet cable to your network or the
Ethernet port of the PC you are using to configure the access point.
WARNING DHCP is enabled by default. If a DHCP server is running on your
network and you have not turned DHCP off, the device will
accept a new IP address when it is connected to your network.
You must use this IP address to configure the device.
Verifying the Hardware
Installation
To verify the hardware installation, complete the following tasks:
• Check the cable connections.
•Check the LED states, as described in Getting to Know the Cisco
AP541N, page 3.

Getting Started with the
Configuration
This section contains information for starting the configuration utility to
provision the access point features. It also describes enabling the radio
that is turned off by default.
You can display the configuration utility by entering the access point IP
address in the URL field of a Web browser. The access point IP address is
the:
•factory default access point static IP address, if it has not been
changed in a previous configuration or replaced by an IP address
assigned by a DHCP server running on the network.
•dynamically assigned IP address allocated to the access point by a
DHCP server.
TIP If you deploy the Cisco AP541N in a Cisco Small Business
Pro network that is running DHCP, you can use
Cisco Configuration Assistant 2.0 or higher to discover the
Cisco AP541N IP address.
The factory defaults are:
Parameter Default Value
username cisco
password cisco
IP connection type DHCP
default IP 192.168.10.10
subnetmask 255.255.255.0
default gateway 192.168.10.1
data VLAN 1
voice VLAN 100
radio Off
data SSID cisco–data (VLAN 1)
