Chapter 1: Introduction
The 2.4 GHz Wireless Access Point is an IEEE 802.11b/g access point that provides transparent, wireless high-speed data communications between the wired LAN and fixed or mobile devices equipped with an 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
802.11b 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.
This solution offers fast, reliable wireless connectivity with considerable cost savings over wired LANs (which include long-term maintenance overhead for cabling). Using
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.
The access point radio interface can operate in one of five modes:
• Access Point – Providing conectivity to wireless clients in the service area.
• AP Client – Act as a wireless clients in the service area.
• Repeater – Providing an extended link to a remote access point from the wired
LAN. In this mode the access point does not have a connection to a wired Ethernet
LAN.
• Bridge – Providing links to other access points in “Bridge” or “Root Bridge” mode connecting wired LAN segments.
• Root Bridge – Providing links to other access points in “Bridge” mode connecting wired LAN segments. Only one unit in the wireless bridge network can be set to
“Root Bridge” mode.
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
HP’s OpenView.
Radio Characteristics – The IEEE 802.11g standard uses a radio modulation technique known as Orthogonal Frequency Division Multiplexing (OFDM), and a shared collision domain (CSMA/CA). It operates at the 2.4 GHz Unlicensed National
Information Infrastructure (UNII) band for connections to 802.1g 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) and Complementary Code Keying (CCK) modulation technology to achieve a communication rate of up to 11 Mbps.
The access point supports a 54 Mbps half-duplex connection to Ethernet networks for each active channel.

Introduction
Component Description
Antennas
The access point includes integrated internal diversity antennas for wireless comunications. 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.
LED Indicators
The access point includes four status LED indicators, as described in the following figure and table.

Hardware Description
Ethernet Port
The access point has one 10BASE-T/100BASE-TX RJ-45 port that can be attached directly to 10BASE-T/100BASE-TX LAN segments. These segments must conform to the IEEE 802.3 or 802.3u specifications.
This 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 LAN to remote workstations on the wireless infrastructure.
Note: The RJ-45 port also 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).
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 power adapter 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.

Chapter 2: Hardware Installation
1.
Select a Site – Choose a proper place for the access point. In general, the best location is at the center of your wireless coverage area, within line of sight of all wireless devices. Try to place the access point in a position that can best cover its Basic Service Set (refer to “Infrastructure Wireless LAN” on page 3-2). For optimum performance, consider these points:
• Mount the access point as high as possible above any obstructions in the coverage area.
• Avoid mounting next to or near building support columns or other obstructions that may cause reduced signal or null zones in parts of the coverage area.
• Mount away from any signal absorbing or reflecting structures (such as those containing metal).
2.
Mount the Access Point – The access point can be mounted on any horizontal surface, wall or suspended ceiling.
Mounting on a horizontal surface – The four attached rubber feet keep the access point from sliding on smooth surfaces.

3.
Connect the Power Cord – Connect the power adapter to the access point, and the power cord to an AC power outlet.
Note: If the access point is connected to both a PoE source device and an AC power source, PoE will be disabled.
Caution: Use ONLY the power adapter supplied with this access point. Otherwise, the product may be damaged.
4.
Observe the Self Test – When you power on the access point, verify that the
Power indicator stops flashing and remains on, and that the other indicators start functioning as described under “LED Indicators” on page 1-4. If the Power
LED turns on amber, the self test has not completed correctly. Refer to
“Troubleshooting” on page A-1.
5.
Connect the Ethernet Cable – The access point can be wired to a
10/100 Mbps Ethernet through a network device such as a hub or a switch.
Connect your network to the RJ-45 port on the back panel with category 3, 4, or
5 UTP Ethernet cable. When the access point and the connected device are powered on, the WAN LED should turn on indicating a valid network connection. If the WAN LED fails to turn on refer to
“Troubleshooting” on page A-1.

Hardware Installation
Note: 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.
Access Point Configuration
The access point can be configured by connecting a PC to its Ethernet port and accessing the web interface. The default IP address of the access point is
192.168.1.50, with default user name and password of ‘admin’.
For detailed information on configuring the access point refer to the Management
Guide.

Chapter 3: Network Configuration
Wireless networks support a stand-alone configuration as well as an integrated configuration with 10/100 Mbps Ethernet LANs. The 2.4 GHz Wireless Access Point also provides repeater and bridging services.
Access points can be deployed to support wireless clients and connect wired LANs in the following configurations:
• Ad hoc for departmental, SOHO or enterprise LANs
• Infrastructure for wireless LANs
• Infrastructure wireless LAN for roaming wireless PCs
• Infrastructure wireless bridge to connect wired LANs
• Infrastructure wireless repeater for extended range
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. up to 3 channels of seperation for 802.11b, or up to 5 channels for 802.11g)

Ad Hoc Wireless LAN
(no Access Point)
An ad hoc wireless LAN consists of a group of computers, each equipped with a wireless adapter, connected via radio signals as an independent wireless LAN.
Computers in a specific ad hoc wireless LAN must therefore be configured to the same radio channel. An ad hoc wireless LAN can be used for a branch office or
SOHO operation.

Infrastructure Wireless LAN
The access point also provides 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 PC in this BSS can talk to any computer 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 connection between mobile workers, as shown in the following figure.

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 adapters and wireless access points within a specific ESS must be configured with the same
SSID.

Infrastructure Wireless Bridge
The IEEE 802.11 standard defines a WIreless Distribution System (WDS) for bridge connections between BSS areas (access points). The access point uses WDS to forward traffic on links between units.
Up to six WDS bridge links can be specified for each unit in the wireless bridge network. One unit only must be configured as the “root bridge” in the wireless network. The root bridge should be the unit connected to the main core of the wired
LAN. Other bridges must configure one “parent” link to the root bridge or to a bridge connected to the root bridge. The other five available WDS links can be specified as
“child” links to other bridges. This forms a tiered-star topology for the wireless bridge network.
When using WDS on the access point radio, only wireless bridge units can associate to each other. Wireless clients can only associate with the access point when the radio is set to access point or repeater mode.

The access point can also operate in a bridge “repeater” mode to extend the range of links to wireless clients. The access point uses WDS to forward traffic between the repeater bridge and the root bridge. The access point supports up to six WDS repeater links.
In repeater mode, the access point does not support an Ethernet link to a wired LAN.
Note that when the access point operates in this mode only half the normal throughput is possible. This is because the access point has to receive and then re-transmit all data on the same channel.

Appendix B: Cables and Pinouts
Twisted-Pair Cable Assignments
For 10/100BASE-TX 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. (See “Straight-Through Wiring” on page B-2 and “Crossover
Wiring” on page B-3 for an explanation.)
Caution: DO NOT plug a phone jack connector into the RJ-45 port. Use only twisted-pair cables with RJ-45 connectors that conform with FCC standards.
The following figure 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.

10/100BASE-TX 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. In straight-through cable, pins 1, 2, 3, and 6, at one end of the cable, are connected straight through to pins 1, 2, 3, and 6 at the other end of the cable.
