Page 6: Introduction
NTRODUCTION The 3Com® Wireless LAN Access Points 8200, 8500, and 8700 offer a dual-mode architecture that supports both 802.11a and 802.11b wireless users on a single device. This means you can mix and match radio bands to meet different coverage and bandwidth needs within the same area. Different access point models give you the flexibility to choose to support both radio modes... -

100 meters (328 feet). ECURITY 3Com offers one of the most robust suite of standards-based security on the market today. To protect sensitive data broadcast over the wireless LAN, 3Com supports Wireless Equivalent Privacy (WEP) RC4 40/ 64-bit, 128-bit and 152-bit shared-key encryption. -
Page 8: Wireless Network Standards
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. -
Page 9: Network Configuration And Planning
The higher spectrum provides about 50 meters (164 feet) of coverage—about half what 802.11b offers. 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 fivefold increase in data throughput 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... -

Ad Hoc Wireless LAN Notebook with Wireless USB Adapter Notebook with Wireless PC Card PC with Wireless PCI Adapter NFRASTRUCTURE IRELESS The access point can also 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. -
Page 11: Infrastructure Wireless Lan For Roaming Wireless Pcs
NFRASTRUCTURE IRELESS OAMING IRELESS The Basic Service Set (BSS) is the communications domain for each access point. For wireless PCs that do not need to support roaming, set the domain identifier (SSID) for the wireless card to the SSID of the access point to which you want to connect. - Page 12 applications, each cell or micro-cell has its own base station; each base station in turn is interconnected with other cells’ bases. BSS—Basic Service Set. It is an access point and all the LAN PCs that are associated with it. CSMA/CA—Carrier Sense Multiple Access with Collision Avoidance. EAP—Extensible Authentication Protocol, which provides a generalized framework for several different authentication methods.

Page 13: Installing The Access Point
The cable must be long enough to reach the power supply or the power-over-Ethernet LAN port. If you use the 3Com power supply, you need an additional Ethernet cable to connect the access point to the LAN. To access and use the Web configuration management system, you need a computer that is running Internet Explorer 5.0 or newer and one of the... -
Page 14: Power Requirements
See “Using the Power Supply” on page 18 and “Using a Power-Over-Ethernet LAN Port” on page 19. Note for use of the 3Com power supply (part number 61-0107-000) in Norway: This product is also designed for use on an IT power system with phase-to-phase voltage of 230 V. -
Page 15: Deciding Where To Place Equipment
CAUTION: The 3Com power supply (part number 61-0107-000) input relies on a 16A rated building fuse or circuit protector for short circuit protection of the line to neutral conductors. CAUTION: It is the responsibility of the installer to ensure that the Power-over-Ethernet (POE) power supply is properly connected. -
Page 16: Before You Begin
EFORE EGIN Record the access point MAC address in a safe place before the access point is installed in a hard-to-reach location. The MAC address is printed on the back of the access point housing. The following illustration shows the front and rear views of the access point, including the LEDs and connecting ports. -

5 straight (8-wire) Ethernet cable. There are two ways to supply power to the access point: Use the 3Com Integrated Power-over-Ethernet power supply. In this case, you need to supply a second Ethernet cable to connect to the wired LAN. -
Page 18: Using The Power Supply
If you supply your own Ethernet cable for connecting power, be sure that it is standard category 5 straight-through (8-wire) cable that has not been altered in any way. Use of nonstandard cable could damage the access point. "To Access Point" "To Hub/Switch"... -
Page 19: Using A Power-Over-Ethernet Lan Port
If your LAN equipment complies with the IEEE 802.3af power-over-Ethernet standard, you can connect the access point directly to a LAN port. For example, the illustration above right shows a connection through a 3Com Ethernet Power ® Supply to a 3Com SuperStack Switch. - Page 20 plate should be placed perpendicular to the floor, with the arrow pointed up, as indicated on the mounting plate, with the smooth side against the wall. Install the mounting plate as shown in the following illustration, on either a stud (or other hard wall surface), or onto drywall. If installing into a stud or other If installing into drywall, use 3 plastic anchors and 3 screws.

Page 21: Flat Surface Installation
Position the access point at an angle to the mounting plate bayonet connection and turn the unit clockwise until it snaps into place, as shown below. Leave at least 13 cm (5 in.) length. Hold the access point at an angle. Turn Ethernet cable may be routed through clockwise to engage and secure it on center opening or through the side. -
Page 22: Selecting And Connecting A Different Antenna Model
If you require a different type of antenna for the Access Point 8200, several options are available by model number from the 3Com Web site (www.3Com.com). (Access Point 8500 does not support interchangeable antennas.) -

protocol is used, and data is protected during the configuration session. When it is turned off, the HTTP protocol is used, and data could be intercepted during the configuration session. Changing this option causes the device to reset, which disrupts the network association temporarily, but does not affect device configuration settings that have already been saved. -
Page 30: Authentication
UTHENTICATION The Authentication page allows you to configure the type of upper-layer authentication the access point uses for wireless clients. Access is checked against the authentication database stored on the access point. This level of authentication occurs before any 802.1x authentication configured on the Security page. -

Page 32: Filtering By Vlan
VLAN ILTERING BY The access point supports filtering of up to 64 VLANs (virtual local area networks). The VLAN IDs must be configured for each client on one of the servers specified on the RADIUS configuration page. When VLAN filtering is enabled, the access point queries the server for the VLAN IDs of associating clients and saves the VLAN IDs. -
