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 the instructions, may
cause harmful interference to radio communications. However, there is no
guarantee that 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 of the following measures:
• Reorient or relocate 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: 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
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with a

Introduction
SMC’s EliteConnect Universal 2.4GHz/5GHz Wireless Access
Point (SMC2555W-AG) is an IEEE 802.11a/g access point that
provides transparent, wireless high-speed data communications
between the wired LAN and fixed, portable or mobile devices
equipped with an 802.11a, 802.11b, or 802.11g wireless adapter.
This solution offers fast, reliable wireless connectivity with
considerable cost savings over wired LANs (which include
long-term maintenance overhead for cabling). Using 802.11a,
802.11b, and 802.11g technology, this access point can easily
replace a 10 Mbps Ethernet connection or seamlessly integrate
into a 10/100 Mbps Ethernet LAN.
In addition, the access point offers full network management
capabilities through an easy to configure web interface, a
command line interface for initial configuration and
troubleshooting, and support for Simple Network Management
tools, such as SMC’s EliteView (available in Q4 of 2003).
Radio Characteristics – The IEEE 802.11a/g standard uses a
radio modulation technique known as Orthogonal Frequency
Division Multiplexing (OFDM), and a shared collision domain
(CSMA/CA). It operates at the 5 GHz Unlicensed National
Information Infrastructure (UNII) band for connections to 802.11a
clients, and at 2.4 GHz for connections to 802.11g clients.
IEEE 802.11g includes backward compatibility with the IEEE
802.11b standard. IEEE 802.11b also operates at 2.4 GHz, but
uses Direct Sequence Spread Spectrum (DSSS) modulation
technology to achieve a communication rate of up to 11 Mbps.

The access point also supports a 54 Mbps half-duplex connection
to Ethernet networks for each active channel (up to 108 Mbps in
turbo mode on the 802.11a interface).

Component Description
Antennas
The access point includes two antennas for wireless
communications. The signal transmitted from both antennas is
identical, but only the best signal received on one of the antennas
is used. The antennas transmit the outgoing signal as a toroidal
sphere, so the antennas should be adjusted to different angles to
provide better coverage. For further information, see “Positioning
the Antennas” on page 2-2.
LED Indicators
The access point includes
four status LED indicators, as
described in the following
figure and table.
LED Status Description
PWR On Indicates that power is being supplied.
Flashing Indicates -
• running a self-test
• loading software program
Flashing
(Prolonged) Indicates system errors
Ethernet
Link On Indicates a valid 10/100 Mbps Ethernet cable link.
Flashing Indicates that the access point is
transmitting or receiving data on a
10/100 Mbps Ethernet LAN. Flashing
rate is proportional to your network
activity.
