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.

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 contains LEDs for “at-a- glance” monitoring of wireless and network port status. It
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 for configuration and monitoring out-of band via a null-modem serial
cable. (See “Console Port Pin Assignments” on page B-3 for wiring options.)
For a detailed description of the access point’s management features, refer to the Foundry
IronPoint 250 User Guide.

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
coverge 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.

Security Slot
The access point includes a Kensington security slot on the rear panel. You can prevent
unauthorized removal of the access point in several ways: by wrapping Foundry’s locking clamp (lock
not provided) or by using a Kensington security cable (not provided).
Console Port
This port is used to connect a console device to the access point through a serial cable. This
connection is described under “Console Port Pin Assignments” on page B-3. The console device can
be a PC or workstation running a VT-100 terminal emulator, or a VT-100 terminal.
Reset Button
This button is used to reset the access point or restore the factory default configuration. If you hold
down the button for less than 5 seconds, the access point will perform a hardware reset. If you hold
down the button for 5 seconds or more, any configuration changes you may have made are removed,
and the factory default configuration is restored to the access point.
Power Connector
The access point does not have a power switch. It is powered on when connected to the AC power
adapter, and the power adapter is connected to a power source. The access point automatically
adjusts to any voltage between 100-240 volts at 50 or 60 Hz. No voltage range settings are required.
The access point may also receive Power over Ethernet (PoE) from a switch or other network device
that supplies power over the network cable based on the IEEE 802.3af standard.
Note that if the access point is connected to a PoE source device and also connected to a local
power source through the AC power adapter, PoE will be disabled.

Network Planning
Network Topologies
The IronPoint 250 supports an integrated configuration with 10/100 Mbps Ethernet LANs.
One or more access points can be configured as:
•
Infrastructure for wireless LANs
•
Infrastructure wireless LAN for roaming wireless PCs
The 802.11b and 802.11g frequency band which operates at 2.4 GHz can easily encounter
interference from other 2.4 GHz devices, such as other 802.11b or g wireless devices, cordless
phones and microwave ovens. If you experience poor wireless LAN performance, try the following
measures:
•
Limit any possible sources of radio interference within the service area
•
Increase the distance between neighboring access points
•
Decrease the signal strength of neighboring access points
•
Increase the channel separation of neighboring access points (e.g., at least 3 channels for
802.11a, or at least 5 channels for 802.11b/g)

Infrastructure Wireless LAN
The IronPoint 250 is designed to provide access to a wired LAN for wireless workstations. An
integrated wired/wireless LAN is called an Infrastructure configuration. A Basic Service Set (BSS)
consists of a group of wireless PC users and an access point that is directly connected to the wired
LAN. Each wireless station in this BSS can communicate with any device in its wireless group via a
radio link, or access other computers or network resources in the wired LAN infrastructure via the
access point.
The infrastructure configuration not only extends the accessibility of wireless PCs to the wired LAN,
but also increases the effective wireless transmission range for wireless PCs by passing their signal
through one or more access points.
A wireless infrastructure can be used for access to a central database, or for a connection between
mobile workers, as shown in the following figure.
Figure 3-1. Infrastructure Wireless LAN

Infrastructure Wireless LAN for Roaming Wireless PCs
The Basic Service Set (BSS) defines the communications domain for each access point and its
associated wireless clients. The BSS ID is a 48-bit binary number based on the access point’s
wireless MAC address, and is set automatically and transparently as clients associate with the
access point. The BSS ID is used in frames sent between the access point and its clients to identify
traffic in the service area.
The BSS ID is only set by the access point, never by its clients. The clients only need to set the
Service Set Identifier (SSID) that identifies the service set provided by one or more access points.
The SSID can be manually configured by the clients, can be detected in an access point’s beacon, or
can be obtained by querying for the identity of the nearest access point. For clients that do not need
to roam, set the SSID for the wireless card to that used by the access point to which you want to
connect.
A wireless infrastructure can also support roaming for mobile workers. More than one access point
can be configured to create an Extended Service Set (ESS). By placing the access points so that a

continuous coverage area is created, wireless users within this ESS can roam freely. All wireless
network cards and access points within a specific ESS must be configured with the same SSID.

Installing the IronPoint 250 Access Point
This section presents procedures for installing the IronPoint 250 access point.
Unpacking the IronPoint Access Point
Unpack the IronPoint 250 access point and make sure the following components are included in the
box:
•
One IronPoint 250 access point
•
One External Power supply and power cable
•
RS-232 console cable
•
IronPoint 250 access point mounting bracket with lock clamp
•
Ceiling tile mounting clamp
•
CD-ROM containing the IronPoint Access Point manuals, drivers, and utility
•
4 adhesive feet
Installing the IronPoint Access Point
Select a location to install the IronPoint 250 access point. The best location is at the center of your
wireless coverage area, within the line of sight of all wireless devices. The access point can be
placed on a horizontal surface or mounted on the wall, with or without the mounting bracket. It can
also be mounted on a suspended ceiling.
Note: For safety reasons, make sure ventilation holes on the access point are positioned
horizontally, not vertically. Allow at least 1 inch (2.54 centimeters) clearance around the ventilation
holes for proper ventilation.
Placing the Access Point on a Desktop or Shelf
Do the following if you want to mount the access point on a horizontal surface, such as a desktop or
shelf:
1. Attach the four adhesive feet to the bottom panel of the access point (Figure 4-1).

Figure 4-1. Attaching Feet to the Access Point
2. Set the access point on its four rubber feet on the desktop, shelf, or flat surface, making sure
there is enough clearance around the ventilation holes for proper air flow. For safety reasons,
make sure ventilation holes on the access point are positioned horizontally, not vertically.
3.
Position the antennas along the same axes. Each antenna emits a radiation pattern that is
toroidal (doughnut shaped), with the coverage extending most in the direction perpendicular to
the antenna. Therefore, the antennas should be oriented so that the radio coverage pattern fills
the intended service area. Also, the diversity antennas should both be positioned along the same
axes, providing the same coverage. For example, if the access point is mounted on a horizontal
surface, both antennas should be positioned pointing vertically up to provide optimum coverage.
Attaching the Access Point to a Wall Using the Mounting Bracket
The access point should be mounted only to a wall or wood surface that is at least 1/2-inch plywood
or its equivalent. To mount the access point on a wall, always use its wall-mounting bracket. The
access point must be mounted with the RJ-45 cable connector oriented upwards to ensure proper
operation.
Do the following to attach the access point to the wall using the mounting bracket:
1. Using the mounting bracket, mark the position of the four screw holes on the wall. For concrete or
brick walls, you will need to drill holes and insert wall plugs for the screws.
2. Position the mounting bracket over the wall screw holes, then insert the included screws and
tighten them down to secure the bracket firmly to the wall. Use 5/8-inch number 12 wood screws
or a near equivalent (not included in the package contents).
3. Attach the access point to the mounting bracket. Line up the two mounting points on the bracket
with the two mounting slots on the bottom of the access point (see the following figure). Place the
mounting points of the bracket into the mounting slots of the bracket, slide it into position so that
the bracket fastening screw on the access point lines up with the tab on the bracket. Then screw
down the fastening screw to secure the access point to the bracket.

specific antenna and cable combinations. For this reason, you must consult with a professional
installer who is trained in RF installation and knowledgeable in the local regulations prior to
connecting an external antenna to your wireless radio product. It is the responsibility of the end user
to ensure that the antenna installation complies with the local radio regulations.
To install an external antenna:
1. Connect the external antenna’s Reverse SMA connector to the access point’s external antenna
connector. Connect 2.4 GHz antennas to the connector labeled "802.11b/g" and 5.0 GHz
antennas to the connector labeled "802.11a."

2. Connect the other end of the RS-232 console cable to your PC's serial port.
3. On your PC console application configure the following communication parameters:
•
9600 bits per second
•
8 data bits
•
No parity
•
1 stop bits
•
No Flow Control
4. Connect the power adapter cable to the 48V DC power socket on the access point and the other
end of the cable to a power source.
CAUTION: Use ONLY the power adapter supplied with this access point. Otherwise, the product
may be damaged.
Adding the IronPoint Access Point to the Network
The access point’s country code and TCP/IP address information must be configured before an
access point can be managed or added to a network. Configuring the correct country code allows
the access point to use the necessary channels and frequencies assigned to your country's wireless
frequency regulations. This must be done prior to using the access point for the first time as the
802.11a and 802.11b/g radios cannot be enabled until the country code has been configured.
Note: Country regulations for wireless products differ from country to country. The access points
may be shipped with the country code already preset, as required by the country, or set to the
default setting of "99." If your country code is pre-set (for example, for United States, Canada,
Japan, and New Zealand), you are prohibited from changing this setting. If country code on your
access point is set to "99," then you may set the country code, but you can set it only to the country
in which the access point is to be used.
It is very important to follow these instructions carefully. Selection of the wrong country code for your
device could result in the device operating outside of authorized frequency/power allocations and
lead to possible legal action by the regulatory authority in your country.
Although Foundry has attempted to provide accurate information in these materials, Foundry
assumes no legal responsibility for the accuracy or completeness of the information. Please note
that Foundry's product information does not constitute or contain any guarantee, warranty or legally
binding representation, unless expressly identified as such in a duly signed writing.
Foundry's IronPoint access point uses TCP/IP to communicate with the management consoles. By
using TCP/IP, you can place access points anywhere in the enterprise and manage them from a
single central location. IronPoint access points do not need to be physically connected to any
wireless LAN switch to be managed.
You can configure the access point’s TCP/IP address information using the Automatic Discovery and
Configuration (ADC) or without using ADC. ADC allows you to rapidly configure a number of access

Foundry IronPoint 250 Installation Guide
points, straight out of the box, by mapping an access point’s MAC address to an IP address, subnet
mask, and default gateway that are defined on an IronPoint-FES interface. Once the access point is
attached to the IronPoint-FES, the switch assigns the predefined IP address, subnet mask, and
default gateway to the access point with the matching MAC address.
The IronPoint 250 is shipped with the ADC feature enabled. If you want to use ADC to configure
TCP/IP address information, refer to the IronView Network Manager User Guide for details.
If you do not want to use ADC, you must override ADC at power-up, so you can enter TCP/IP
information. Do the following:
1. Once the access point powers up, a prompt to override ADC appears. Enter the following ADC
override login ID and password on your PC console to override ADC:
ADC-Override-Login: admin
ADC-Override-Password: admin
2. Enter the default administrator user name and password on to gain access to the CLI:
Username: admin
Password: admin
3. Disable ADC by entering the following command:
Foundry AP#configure
Foundry AP(config)#no adc enable
Foundry AP(config)#end
Note: If you do not disable ADC, the ADC-Override Login prompt will keep appearing every time
the access point reboots.
4. Set the correct country code with the country command. For example, to set the country code to
the United Kingdom, enter:
Foundry AP#country

Making a Network Connection
Connecting to a Network Device
The IronPoint 250 is designed to connect a wired Ethernet network to wireless clients. It can be
connected to any Ethernet network device, such as a hub or switch.
Twisted-Pair Cable
The access point’s Ethernet port connection requires an unshielded twisted-pair (UTP) cable with
RJ-45 connectors at both ends. For 100BASE-TX connections, Category 5 or better cable is
required; for 10BASE-T, Category 3 or better cable can be used.
Cabling Guidelines
The RJ-45 port on the access point supports automatic MDI/MDI-X operation, so you can use
straight-through cables for all network connections to PCs, switches, or hubs.
See Appendix B for further information on cabling.
Caution: Do not plug a phone jack connector into the RJ-45 port. This will damage the access point.
Use only twisted-pair cables with RJ-45 connectors that conform to FCC standards.

CAUTION: DO NOT plug a phone jack connector into any RJ-45 port. Use only twisted-pair cables
with RJ-45 connectors that conform with FCC standards.
For 100BASE-TX/10BASE-T connections, a twisted-pair cable must have two pairs of wires. Each
wire pair is identified by two different colors. For example, one wire might be green and the other,
green with white stripes. Also, an RJ-45 connector must be attached to both ends of the cable.
CAUTION: Each wire pair must be attached to the RJ-45 connectors in a specific orientation.
Figure B-1 illustrates how the pins on the RJ-45 connector are numbered. Be sure to hold the
connectors in the same orientation when attaching the wires to the pins.

100BASE-TX/10BASE-T Pin Assignments
Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45 connections:
100-ohm Category 3 or better cable for 10 Mbps connections, or 100-ohm Category 5 or better cable
for 100 Mbps connections. Also be sure that the length of any twisted-pair connection does not
exceed 100 meters (328 feet).
The RJ-45 port on the access point supports automatic MDI/MDI-X operation, so you can use
straight-through or crossover cables for all network connections to PCs, switches, or hubs.
