PowerGreen. This LED indicates that the Router’s power is on. Link/ActGreen. This LED serves two purposes. When this LED is lit continuously, this indicates that the Router is connected to a device through the corresponding port (1, 2, 3, or 4). A blink- ing LED indicates that the Router is actively sending or receiving data over that port. When the Uplink Port is in use, the LED for Port 4 will be lit continuously. 6 The Wireless Access Point Router’s LEDs TThhee RReesseett BBuuttttoonn Pressing the Reset Button and holding it in for a few seconds will clear all of the Router’s data and restore the factory defaults. This should be done only if you are experiencing heavy routing problems, and only after you have exhausted all of the other troubleshooting options. By resetting the Router, you run the risk of creating conflicts between your PCs’ actual IP Addresses and what the Router thinks their IP Addresses should be. You may be forced to reboot each network PC. If the Router locks up, simply press the reset button or power it down for three to five seconds by removing the power cable from the Router’s Power Port. Leaving the power off for too long could result in the loss of network connections. Figure 1-2 The Router’s rear panel (as shown in Figure 1-1) is where all of its connections are made. WA NThe WAN (Wide Area Network) Port is where you will con- nect your cable or DSL modem with an Ethernet cable. Your modem connection will not work from any other port. Ports 1-4These four LAN (Local Area Network) ports are where you will connect networked devices, such as PCs, print servers, and any other Ethernet devices you want to put on your net- work. If Port 4 is being used, the Uplink Port will not work. UplinkThe Uplink Port is where you can expand your network by connecting to another switch or hub. Uplinking to another switch or a hub is done by simply running a cable from the Uplink Port to the other device. The Uplink Port is shared with Port 4. If the Uplink port is being used, Port 4 will not work. PowerThe Power Port is where you will connect the included AC Power adapter. Antenna JacksThe Antenna Jacks are where the included antennas are con- nected. Figure 1-1 The Wireless Access Point Router’s Ports Instant Wireless TM Series Wireless Access Point Router with 4-Port Switch 5 Chapter 2: Connecting the Router Before plugging everything together, it’s always a good idea to have everything you’ll need to get the Router up and running. Depending upon how you config- ure the Router in Chapter 4: Configuring the Router, you may need some of the following values from your ISP: When connecting through a Static IP connection, be sure to have 1) Your broadband-configured PC’s fixed Internet IP Address, 2) Your broadband- configured PC’s Computer Name and Workgroup Name, 3) Your Subnet Mask, 4) Your Default Gateway, and 5) Your Primary DNS IP address. When connecting through a PPPoE connection, be sure to have 1) Your PPPoE User Name and 2) Your PPPoE Password. The installation technician from your ISP should have left this information with you after installing your broadband connection. If not, you can call your ISP to request the data. Once you have the above values, you can begin the Router’s installation and setup. Once you are sure that you have the above values on hand, you can begin the Installation and Setup of the Router. 1. Power everything down, including your PCs, your cable or DSL modem and the Router. 2. Connect an Ethernet cable from one of your PC’s Ethernet ports to one of the Router’s LAN ports (as shown in Figure 2- 1). Do the same with all the PCs you wish to connect to the Router. (LAN Port 4 will become inactive if you use the Uplink port.) In addition to accessing the Router through an Ethernet connection, a wireless connec- Before You Start Full/ColGreen.

Chapter 3: Configuring the PCs These instructions will help you configure each of your computers to commu- nicate with the Router. To do this, you will need to configure your PC’s network settings to obtain an IP (or TCP/IP) address automatically. Computers use IP addresses to commu- nicate with each other across a network or the Internet. You will need to know which operating system your computer is running, such as Windows 95, 98, Millennium, 2000, or XP. You can find out by clicking the Startbutton and then selecting the Settingsoption. (If your Start menu does- n’t have a Settings option, you’re running Windows XP. You can select the Control Panel directly from the Start Menu.) Then, click Control Paneland double-click the Systemicon. Click the Cancel button when done. Once you know which Windows operating system you are running, follow the directions in this step for your computer’s operating system. If you PC is not configured with the TCP/IP protocol, you will need to do this for each com- puter you are connecting to the Router. The next few pages tell you, step by step, how to configure your TCP/IP set- tings based on the type of Windows operating system you are using. Once you've configured your computers, continue to Chapter 4: Configuring the Router. 1. Click the Startbutton, click Settingsand open the Control Panel. From there, double-click the Networkicon to open the Network screen. 12 Overview Configuring Windows 95, 98, and Millennium PCs Figure 3-1 Figure 3-2 Instant Wireless TM Series Wireless Access Point Router with 4-Port Switch 11 5.

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 March 27, 2003 RE: Linksys Group Inc. FCC ID: PKW-BEFW11S4V32 After a review of the submitted information, I have a few comments on the above referenced Application. 1) Please provide a detailed close up photograph of the RF section of the device with the sub-shields removed. Additionally, if the RF portion is a separate Card, photographs of the main board with the card removed, and also bottom views of the Card itself must be provided. (Note block diagram shows the RF as a separate Card). 2) Please provide a schematic for the transmitter board. This is required by 2.1033(b)(5) for the RF section. As an alternative, you may provide a parts list that lists the RF board as a part provided by another manufacturer. Depending on the items provided, the letter of confidentiality may need to be adjusted to cover the parts list. 3) The users manual page 105 states that the output power is 19 dBm. However the maximum measured output power was 16.4 dBm. The output power should be consistent to within 0.5 dB throughout the application. Please correct the users manual. 4) The required statements given in 15.21 should be added to the users manual. Additionally, the users manual is missing information regarding RF exposure statements. Please provide a corrected users manual. 5) Note: We are also awaiting an updated users manual as Bill Graff had discussed with you due to the large size of the files provided. 6) The delta's given on page 45 of the test report are incorrect.

ADDRESS: 17401 Armstrong Ave. Irvine, CA 92614 ISSUED BY: Advance Data Technology Corporation LAB LOCATION: No. 81-1, Lu Liao Keng, 9 Ling, Wu Lung Tsuen, Chiung Lin Hsiang, Hsin Chu Hsien, Taiwan, R.O.C. 0536 ILAC MRA Lab Code: 200376-0 FCC ID: PKW-BEFW11S4V32 ADT No.: 920218H02 RF Exposure Measurement (Mobile Device) 1. Introduction 2.4 GHz frequency band is regarded specially as a dangerous band for its heating harmfulness to the human body. That’s why microwave oven is operating in this frequency band. The manufacturer whose product is working in this frequency band is obligatory to prove the harmfulness of his product. In this document, we try to prove the safety of radiation harmfulness to the human body for our product. The limit for Maximum Permissible Exposure (MPE) specified in FCC 1.1310 is followed. The Gain of the antenna used in this product is measured in a Fully Anechoic Chamber (FAC), and the maximum total power input to the antenna is measured. Through the Friis transmission formula and the maximum gain of the antenna, we can calculate the distance, away from the product, where the limit of MPE is reached. 2. Classification The antenna of the product, under normal use condition, is at least 20 cm away from the body of the user. Warning statement for keeping 20 cm separation distance and the prohibition of operating next to a person has been printed on the users manual. So, this product is classified as the Mobile Device. 3. RF Exposure Limit According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environmental impact of human exposure to radio-frequency (RF) radiation as specified in 1.1307(b). FCC ID: PKW-BEFW11S4V32 ADT No.: 920218H02 LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) Frequency Range (MHz) Electric Field Strength (V/m) Magnetic Field Strength (A/m) Power Density (mW/cm 2 ) Average Time (minutes) (A)Limits For Occupational / Control Exposures 30-30061.40.1631.06 300-1500......F/3006 1500-100,000......56 (B)Limits For General Population / Uncontrolled Exposure 30-30027.50.0730.230 300-1500......F/150030 1500-100,000......1.030 F = Frequency in MHz 4. Friis Formula Friis transmission formula : Pd = (Pout*G) / (4*pi*r 2 ) where Pd = power density in mW/cm 2 Pout = output power to antenna in mW G = gain of antenna in linear scale Pi = 3.1416 R = distance between observation point and center of the radiator in cm Pd is the limit of MPE, 1 mW/cm 2 . If we know the maximum Gain of the antenna and the total power input to the antenna, through the calculation, we will know the distance r where the MPE limit is reached. Ref. : David K. Cheng, Field and Wave Electromagnetics, Second Edition, Page 640, Eq. (11-133). 5. EUT Operating condition The software provided by Manufacturer enabled the EUT to transmit and receive data at lowest, middle and highest channel individually. FCC ID: PKW-BEFW11S4V32 ADT No.: 920218H02 6. Test Results 6.1 Antenna Gain The maximum Gain measured in Fully Anechoic Chamber is 2Bi or 1.58 (numeric). 6.2 Output Power Into Antenna & RF Exposure Distance : CHANNEL CHANNEL FREQUENCY (MHz) OUTPUT POWER TO ANTENNA (mW) MINIMUM ALLOWABLE DISTANCE ( r ) FROM SKIN (Centi-Meter) 1241239.452.23 6243740.741.77 11246243.152.33 The minimum allowable distance is very close to the enclosure of the antenna. So, the user has no need to worry about the harmfulness of radiation. But it is recommended to always keep, at least, 20 cm separation distance with the antenna.
