Preface

Introduction

The Nortel Networks Wireless LAN Access Po int 2220 (Access Point 2220) is an access point that provides transparent, wireless high-speed data communications between the wired LAN and fixed, portable or mobile devices equipped with an

802.11a/802.11b (or A only card or B only card) wireless adapter employing the same radio modulation.

This solution offers fast, reliable wireless c onnectivity with considerable cost savings over wired LANs (which include long-term maintenance overhead for cabling). Using 802.11a,11b technology, the Access Point 2220 can easily replace a 10 Mbps Ethernet connection or seamlessly integrate into a 10/100 Ethernet LAN.

Package Checklist

The Access Point 2220 package includes:

• One Access Point 2220

• Driver & Utility CD

• Documentation CD

Hardware Description

Ethernet Compatibility

The Access Point 2220 can attach directly to 10BASE-T/100BASE-TX (twisted-pair) Ethernet LAN segments. These segments must conform to the IEEE

802.3 specification.

Using the Nortel Networks Wireless LAN Access Point 2220

[Final Draft—Nortel Confidential]

14 Preface

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

Radio Characteristics

For the A radio, the Access Point 2220 uses a radio modulation technique known as Orthogonal Frequency Division M ultiplexing (OFDM), and a shared collision domain (CSMA/CA). It operates at the 5GHz Unlicensed National Information Infrastructure (UNII) band with turbo mode. Data is transmitted over a half-duplex radio channel operating at up to 108 Megabits per second (Mbps) in turbo mode. The default mode is 54 Mbps.

Power over E thernet

The Access Point 2220 supports Power over Ethernet ( PoE). You need not configure anything to access power from a IEEE 802.3af-draft-compliant switch.

To use PoE to power your Access Point 2220, plug in a c able to the RJ-45 port on the back of the Access Point 2220 and c onnect the other end of the RJ-45 cable to a switch that delivers IEEE 802.3af-draft-compliant power.

When you are using PoE, you do not require separate AC power. The Access Point 2220 draws 8.5 W.

The Access Point 2220 uses both spare and signal RJ-45 power pairs.

LED Indicators

The Access Point 2220 includes four status LED indicators, as described in the following figure and table.

16 Preface

System Requirements

Before you install the Access Point 2220, be sure you can meet the following requirements:

• AnA/C power outlet (100~240 V,50~60 Hz) which will supply power for the access point (Alternatively, you can plug into a switch that delivers Power over Ethernet to power the Access Point 2220.)

• 802.11a or 802.11b compliant (or dual-compliant)wireless Ethernet adapters with TCP/IP compatible protocol installed

• Web browser for configuration Alternatively, you can connect an RS-232 cable to the console port and use the

command line interface (CLI). For more information on the CLI, refer to Run

Time Console Specifications.

Optivity* NMS also works with the Access Point 2220.

Chapter 1 Hardware Installation

1 Placement of the Access Point 2220 – Choose a proper place for your Access

Point 2220. 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 B SS. Normally, the higher you place the access point, the better the performance. (Refer to Appendix B,

“Template for placing the Access Point 2220,” for information on mounting

the Access Point 2220.)

2 Connect the Console Port – Connect the console cable to the RS-232 console

port for accessing the command-line interface. (Refer to “Run Time Console Specifications“ for complete information on the CLI.) You can manage the access point through this console connection, or the Web management interface (refer to “System Configuration” on page 19.)

3 Connect the Ethernet Cable – The Access Point 2220 can be wired to a 10/100

Mbps Ethernet through a networkdevicesuchas a hub or a switch. C onnect to the RJ-45 connector socket on the back panel with category 3, 4, or 5 UTP Ethernet cable and an RJ-45 connector.

4 If you are not using PoE, use the separately orderable power adapter –

Connect the power adapter cable to the 5 VDC power socket on the rear panel.

Warning:Use ONLY the poweradaptersuppliedby Nortel Networks for this product. Otherwise, the product may be damaged. Contact your Nortel Networks representative to order the power adapter.

Chapter 2 System Configuration

The Access Point 2220 can be configured by any Java-supported Web browser including Internet Explorer 4.0 or above, or NetScape Navigator 4.0 or above. Using the Web management interface, you may c onfigure the Access Point 2220. You can also use the command line interface (CLI) to manage the Access Point

2220. (Refer to “Run Time Console Specifications“ for complete information on

the CLI.)

To initially manage the Access Point 2220, you m ust configure the network settings of the computers on your wireless LAN to use the same IP subnet as the Access Point 2220. The default network settings assuming there is no external DHCP server for this device are:

Access Point IP Address: 192.168.168.10 Gateway IP Address: 192.168.168.254 Subnet Mask: 255.255.255.0

Chapter 2 System Configuration 19

The IP address of the c onnected client P C from which system configuration is to be performed should be 192.168.168.x (where x m eans 1–9, 11–253).

If DHCP is enabled, (default setting is “Enable,” page 41) a nd a DHCP server is located on the network, then the access point will automatically be assigned an IP address when booted.

To a ccess the Access Point 2220’s management interface, enter the IP a ddress of the device in your Web browser:

http://192.168.168.10

The Web management window will appear.
