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 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 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.

FCC Channel Use Statement:

The equipment version marketed in US is restricted to usage of the channels 1- 11 only.

Wireless 2.4 Ghz and 5 GHz Band Statements:

As the IronPoint can operate in the 5150-5250 MHz frequency band it is limited by the FCC, Industry Canada
and some other countries to indoor use only so as to reduce the potential for harmful interference to co-channel
Mobile Satellite systems.

High power radars are allocated as primary users (meaning they have priority) of the 5250-5350 MHz and
5650-5850 MHz bands. These radars could cause interference and/or damage to the IronPoint when used in
Canada.

The term “IC:” before the radio certification number only signifies that Industry Canada technical specifications
were met.

Industry Canada - Class B

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 Industry Canada.

Cet appareil numérique respecte les limites de bruits radioélectriques applicables aux appareils numériques de
Classe B prescrites dans la norme sur le matérial brouilleur: “Appareils Numériques,” NMB-003 édictée par
l’Industrie.

Industry Canada Statement

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 device has been designed to operate with an antenna having a maximum gain of 13 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.

Because high power radars are allocated as primary users (meaning they have priority) in 5250-5350 MHz,
these radars could cause interference and/or damage to license exempt LAN devices.

About the IronPoint 250

Overview

Foundry’s IronPoint 250 is an IEEE 802.11a/g enterprise wireless access point that provides high­speed data communications between the wired LAN and fixed, portable or mobile devices equipped
with an 802.11a, 802.11b, or 802.11g wireless network card.

The access point offers full network management capabilities through a command line interface for
initial configuration and troubleshooting, a Web interface, and Simple Network Management tools.

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).

Management Options

The

IronPoint 250
also includes a built-in network management agent that allows the access point to be managed in­band using SNMP, with a Web browser, or remotely via Telnet and SSH. The access point provides
an RS-232 DCE serial port (DB-9 connector) on the front panel for out-of-band management. A PC
may be connected to this port
cable. (See “Console Port Pin Assignments” on page B-3 for wiring options.)

contains LEDs for “at-a- glance” monitoring of wireless and network port status. It

null-modem serial

About the IronPoint 250

Description of Hardware

Ethernet Port

The access point has one 10BASE-T/100BASE-TX RJ-45 Ethernet port that can be attached directly
to a 10BASE-T/100BASE-TX/1000BASE-T wired network. The wired network must conform to the
IEEE 802.3-2005 specifications.

The Ethernet port supports automatic MDI/MDI-X operation, so you can use straight-through cables
for all network connections to PCs, switches, or hubs.

The access point appears as an Ethernet node and performs a bridging function by moving packets
from the wired network to remote workstations in the wireless infrastructure.

Note: The RJ-45 port supports Power over Ethernet (PoE) based on the IEEE 802.3af standard.
Refer to the description for the “Power Connector” for information on supplying power to the access
point’s network port from a network device, such as a switch, that provides Power over Ethernet
(PoE).

Antennas

The access point includes two integrated diversity antennas for wireless communications. A diversity
antenna system uses two identical antennas to receive and transmit signals, helping to avoid
multipath fading effects. When receiving, the access point checks both antennas and selects the one
with the strongest signal. When transmitting, it will continue to use the antenna previously selected
for receiving. The access point never transmits from both antennas at the same time.

The antennas transmit the outgoing signal as a toroidal sphere (doughnut shaped), with the
coverage extending most in a direction perpendicular to the antenna. The antenna should be
adjusted to an angle that provides appropriate coverage for the service area. For further information,
see “Installing the IronPoint Access Point” on page 4-1.

Optional External Antenna

The access point supports RP-SMA external antenna connectors for both the 2.4 GHz and 5 GHz
radios. External antennas offer a variety of options for extending the radio range and shaping the
coverage area. When an external antenna is connected, you must manually configure the software
to disable the two integrated antennas and uses only the external antenna.
