1 INTRODUCTION
The 3Com AirConnect 9550 11n 2.4+5GHz PoE Access Point and the 3Com AirConnect 9150 11n 2.4GHz PoE Access Point are high performance access points that allow you to join isolated wired Ethernet networks into a unified wireless local area network (WLAN). The Access Point (AP) supports Wi-Fi Protected Access security standards to provide a higher level of security for network data and communications. The AP is also fully compatible with IEEE 802.11a (the 9550 AP only), 802.11b, 802.11g, and 802.11n.
Key Product Features
The product operates using 11a (9550 AP only), 11b, 11g, or 11n modes. This AP creates an enterprise-class wireless LAN, supporting up to 64 simultaneous users.
Security
3Com offers one of the most robust suites of standards-based security on the market today. To protect sensitive data broadcast over the wireless LAN, 3Com supports Wireless Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA and WPA2).
8 |
Key Product Features |
3Com strengthens this basic security mechanism with additional security features, including MAC address access control lists, IEEE 802.1x per-port user authentication with RADIUS server authentication support, Temporal Key Integrity Protocol (TKIP), Advanced Encryption Standard (AES), Wireless Protected Access (WPA) and Extensible Authentication Protocol (EAP) support: EAP-MD5, EAP-TLS, EAP-TTLS, and PEAP.
Performance and Reliability
3Com wireless access point performance features ensure reliable and seamless connections for users wherever they roam. Automatic channel selection automatically finds the least loaded channel for interference-free communication. Auto network connect and dynamic rate shifting keep users connected through a wide variety of conditions by changing to the optimum connection speed as they move through the network.
Manageability
3Com offers a wide range of standards-based management support, from SNMP to 3Com Network Supervisor and HP OpenView for seamless integration with your wired network.
Wireless Infrastructure Device Manager and Wireless LAN Device Discovery tools let you configure parameters, run diagnostics, backup and restore configurations, and monitor performance from anywhere on the network using an embedded web server browser.

With Power over Ethernet (PoE) support, the same Category 5 cable that connects your access point to the data network also provides its power. A single cable installation dramatically improves your choice of mounting configurations because you no longer need to consider AC power outlet locations. PoE support makes it easier than ever to overcome installation problems with difficult-to-wire or hard-to-reach locations.
Wireless Network Standards
Understanding the characteristics of the 802.11a and 802.11g standards can help you make the best choice for your wireless implementation plans.
802.11a
Ratified in 2002, 802.11a operates at the 5GHz band and supports data rates at up to 54Mbps. Because there are fewer devices in the 5GHz band, there’s less potential for RF interference. However, because it is at an entirely different radio spectrum, it is not compatible with 802.11b and 802.11g.
The higher spectrum provides about 50m (164ft) of coverage. Consider 802.11a when you need high throughput in a confined space and you are:
■Running high-bandwidth applications like voice, video, or multimedia over a wireless network that can benefit from a five-fold increase in data throughput.
10Key Product Features
■Transferring large files like computer-aided design files, preprint publishing documents or graphics files, such as MRI scans for medical applications that demand additional bandwidth.
■Supporting a dense user base confined to a small coverage area. Because 802.11a has a greater number of non-overlapping channels, you can pack more wireless devices in a tighter space.
802.11b/g
802.11b, 802.11g and 802.11n all operate in the 2.4GHz band. 802.11b can support data rate up to 11Mbps. 802.11g can support data rate up to 54Mbps. 802.11n can support data rate up to 300Mbps.They all support the widest coverage – up to 100m (328ft). It is however, subject to a greater risk of radio interference because it operates in the more popular 2.4GHz band.
Consider 802.11n when you need wider coverage and vendor compatibility and you are:
■Maintaining support for existing 802.11b and 802.11g users and the existing wireless investment while providing for expansion into 802.11n.
■Implementing a complete wireless LAN solution, including Ethernet Adapters, gateways, access points and clients; Wi-Fi certification guarantees compatibility among vendors.
Key Product Features |
11 |
■Providing access to hot spots in public spaces such as coffee shops or university cafeterias.
IEEE 802.3af
The IEEE 802.3af-2003 Power over Ethernet (PoE) standard defines terminology to describe a port that acts as a power source (PSE) to a powered device (PD). The IEEE 802.3af standard states that power may be delivered by an end-point PSE, using either the active data wires of an Ethernet port or the spare wires, to a powered device. An end-point PSE, such as a Power over Ethernet capable Ethernet switch, may implement either scheme. If a mid-span PSE is used, then the mid-span PSE can only implement power delivery over the spare pairs of the copper cabling and cannot be used to deliver PoE over 1000BASE-T connections. It should be noted that even if a device supports both methods of providing power, only one mechanism may be used to deliver power to a powered device.
The first mechanism is to use the data pairs (pins 1, 2 & 3, 6) to transmit power, which is sometimes referred to as "phantom" power. The second power delivery mechanism is to use the unused, from a 10/100BASE-T perspective, pairs (pins 4, 5 & 7, 8) to deliver power that is supported within mid-span power delivery.

Installing Your 3com Wireless Access Point
To set up and install your 3Com Wireless Access Point, please refer to the 3Com® AirConnect® 9550 11n 2.4+5GHz PoE Access Point 3CRWE955075 / WL-605 3Com® AirConnect® 9150 11n 2.4GHz PoE Access Point 3CRWE915075 / WL-604 Quick Start Guide (Part Number 10016854).

CONFIGURING THE WIRELESS |
|
ACCESS POINT |
If the default AP configuration does not meet your network requirements, or if you want to customize the settings for your own network, you can use these tools to change the configuration:
■Launch the 3Com Wireless Infrastructure Device Manager (Widman) utility
■Directly connect to the device through its Ethernet port or console port
Networks with a DHCP Server
If your network has a DHCP server, an IP address is automatically assigned to the AP. It takes between one and two minutes for the Access Point to determine if there is a DHCP server on the network. Use the 3Com Wireless Infrastructure Device Manager (Widman) included on the 3Com Installation CD to locate the Access Point on the network and view its IP address.
14 |
Networks without a DHCP Server |
After you determine the AP’s IP address, you can enter that IP address into a web browser on a computer on the same subnet to view the Access Point’s system status or change its configuration.
Networks without a DHCP Server
If your network does not have a DHCP server, the Access Point uses a factory assigned IP address (169.254.2.111). You can use that IP address to configure the Access Point, or you can assign a new IP address to the Access Point.
To verify that the Access Point is using the default IP address assigned at the factory:
1Connect a computer directly to the Access Point using the supplied standard Category 5 UTP Ethernet cable.
2Enter the Access Point’s default IP address (169.254.2.111) into the computer’s web browser. If the Configuration Management System starts, the Access Point is using the factory assigned IP address. You can configure the Access Point with the following login information:
■Login name: admin
■Password: password
If the Configuration Management System does not start, the Access Point is on a different subnet than the computer. Install and start the 3Com Wireless Infrastructure Device Manager to discover the Access Point’s IP address.
