FCC - Class B
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with instructions, may cause
harmful interference to radio communications. However, there is no guarantee that
the interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
• Reorient the receiving antenna
• Increase the separation between the equipment and receiver
• Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected
• Consult the dealer or an experienced radio/TV technician for help
FCC Caution: To assure continued compliance, (example - use only shielded
interface cables when connecting to computer or peripheral devices) any changes
or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate this equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) This device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that
may cause undesired operation.
IMPORTANT NOTE:
FCC Radiation Exposure Statement
FCC Radiation Exposure Statement: This equipment complies with FCC radiation
exposure limits set forth for an uncontrolled environment. This equipment should
be installed and operated with a minimum distance of 20 centimeters (8 inches)
between the radiator and your body. This transmitter must not be co-located or
operating in conjunction with any other antenna or transmitter.
SMC declared that SMC2870W is limited in CH1~11 from 2400 to 2483.5 MHz by
specified firmware controlled in USA.

Industry Canada - Class B
Operation is subject to the following two conditions:
1) this device may not cause interference and
2) this device must accept any interference, including interference that may cause
undesired operation of the device
This digital apparatus does not exceed the Class B limits for radio noise emissions
from digital apparatus as set out in the interference-causing equipment standard
entitled “Digital Apparatus,” ICES-003 of the Department of Communications.
Cet appareil numérique respecte les limites de bruits radioélectriques applicables
aux appareils numériques de Classe B prescrites dans la norme sur le matériel
brouilleur: “Appareils Numériques,” NMB-003 édictée par le ministère des
Communications.
This device has been designed to operate with an antenna having a maximum
gain of 1.5 dBi.
Antenna having a higher gain is strictly prohibited per regulations of Industry
Canada. The required antenna impedance is 50 ohms.
To reduce potential radio interference to other users, the antenna type and its gain
should be so chosen that the EIRP is not more than required for successful
communication.
To prevent radio interference to the licensed service, this device is intended to be
operated indoors and away from windows to provide maximum shielding.
Equipment (or its transmit antenna) that is installed outdoors is subject to
licensing.

Introduction
SMC’s EZ Connect 2.4 GHz Wireless Ethernet Bridge
(SMC2870W) can function as:
•an Ethernet adapter, providing a wireless connection via an
RJ-45 connection to devices such as Microsoft Xbox and
Ethernet ready embedded devices
•a standard IEEE 802.11g access point
•a wireless repeater, allowing you to effectively extend the
coverage of another SMC2870W that is configured to operate
in Access Point mode
This solution offers fast, reliable wireless connectivity with
considerable cost savings over wired LANs (eliminates long-term
maintenance overhead for cabling). Just install enough wireless
access points to cover your network area, plug wireless cards into
your notebooks or install wireless adapters into your desktops,
and start networking.
Use this device in conjunction with SMC’s EZ Connect Wireless
Cards to create an instant network that integrates seamlessly
with Ethernet LANs. Moreover, moving or expanding your network
is as easy as moving or installing additional access points – no
wires!

H ARDWARE D ESCRIPTION
The Wireless Ethernet Bridge supports 1, 2, 5.5 and 11 Mbps
half-duplex connections to Ethernet networks. This device is fully
compliant with 2.4 GHz DSSS/OFDM wireless networking as
defined in IEEE 802.11b/g. The Wireless Ethernet Bridge is
backward compatible with the existing 802.11b WLAN
infrastructure. It also can be connected via an RJ-45 connection
to devices such as Nintendo GameCube, Microsoft Xbox, Sony
PlayStation II, and Ethernet ready embedded devices. It functions
as an IEEE 802.11g Access Point or as a Repeater (see
“Introduction” on page 1).
Figure 1. Rear Panel
Note: If you use the RELOAD button at the bottom, the Wireless
Ethernet Bridge performs a power reset. If the button is
depressed for over 5 seconds, all the LEDs will illuminate
and the factory settings will be restored.

System Requirements
Before you install the Wireless Ethernet Bridge, be sure you have
met the following requirements:
•An AC power outlet (100~240 V, 50~60 Hz)
•An available RJ-45 (UTP) port on an Ethernet hub or switch
•802.11b/g compliant wireless Ethernet adapters with TCP/IP
protocols installed
•TCP/IP network protocol installed on each PC that needs to
access the Internet
•A web browser, such as Microsoft Internet Explorer 5.5 or
above installed on one PC at your site for configuring the
Wireless Ethernet Bridge

H ARDWARE I NSTALLATION
1. Select the site – Choose a location for your Wireless Ethernet
Bridge. Usually, the best location is at the center of your
wireless coverage area, if possible within line-of-sight of all
wireless devices.
2. Place the Wireless Ethernet Bridge in a position that gives it
maximum coverage. Normally, the higher you place the
antenna, the better the performance.
3. Position the antennas in the desired positions. For more
effective coverage, position the antennas along different axes.
For example, try positioning the antennas around 45 to 90
degrees apart. (The antennas emit signals along the
toroidal plane – and thus provide more effective
coverage when positioned along different axes.)
4. If used in Client Bridge mode, connect the Ethernet cable to
the RJ-45 socket of the device that will communicate over a
wireless connection with an access point.
5. If used in Acces Point mode, connect the SMC2870W to an
Ethernet network device such as a hub or a switch using
category 3, 4, or 5 UTP Ethernet cable and an RJ-45
connector.
6. Connect the power adapter cable to the 5 VDC power socket
on the rear panel.
Warning: Use only the power adapter supplied with the
SMC2870W.

S YSTEM C ONFIGURATION
The SMC2870W is a Plug-and-Play device. This means that, in
most cases, you will not need to configure it.
The SMC2870W Wireless Ethernet Bridge includes an SNMP
agent that is accessible through an SNMP manager application
(Refer to “Using the Configuration Utility” on page 11.) The latest
version may be downloaded from the SMC web site specified on
the back cover of this manual.
The SMC2870W can be configured by a web browser, specifically
Internet Explorer 5.5 or above. Using the web management
interface, you can configure the Wireless Ethernet Bridge and
view statistics to monitor network activity.
Before you attempt to log into the SMC2870W’s web-based
administration, please verify the following.
1. Your browser is configured properly (see below).
2. Disable any firewall or security software that may be running.
3. Confirm that you have a good link LED where your computer
is plugged into the Wireless Ethernet Bridge. If you don’t have
a link light – then try another cable to get a good link.
4. To access the Internet through the Wireless Ethernet Bridge,
you must configure the network settings of the computers on
your LAN to use the same IP subnet as the Wireless Ethernet
Bridge. The default network settings for the Wireless Ethernet
Bridge are:
SMC2870W IP Address: 192.168.2.25
Subnet Mask: 255.255.255.0
