OPTIMIZING YOUR COMPUTER Before you can configure the LAN Modem for Internet access, each computer must be properly set up with TCP/IP and optimized for use with the LAN Modem. Follow the instructions below for your operating system. If you already know that you will be connecting to a static IP network, the EZ-LAN Wizard can attempt to optimize your network settings to allow you to access the initial LAN Modem configuration screens. If you have difficulty, or if you prefer to follow a more detailed manual procedure, refer to the instructions in Chapter 3 of the User Guide instead of running the EZ-LAN Wizard. Windows 95, 98, 2000 and NT: Run the EZ-LAN Wizard from the OfficeConnect Dual 56K Companion Programs CD-ROM. EZ-LAN checks the settings on your computer and, if you choose, optimizes them for use with the LAN Modem. Be sure to run the EZ-LAN Wizard on all PCs that you plan to network. Macintosh: Perform this simple check to verify that the settings on your computer or computers are optimized for use with the LAN Modem: 1 From the Apple menu, select Control Panels, and then TCP/IP. 2 In the Connect Via field, select Ethernet (if iMac, select Ethernet built-in). 3 Look at the Configure field entry. If it is set to Using DHCP Server and all other fields are blank or set to <will be supplied by server>, then you are ready to continue directly with Step 2, “Installing the LAN Modem.” If Configure is set to anything other than Using DHCP Server (there are specific values in any of the other fields), your computer may have a static IP address. Refer to Chapter 3 of the User Guide to perform additional steps not covered in this Getting Started Guide. STEP 3. CONFIGURING FOR INTERNET ACCESS 4 Before You Start the Configuration, have the following information ready: ■ ■ ■ ■ ■ Your analog telephone number or numbers ISP telephone number ISP account user ID ISP account password (including ISP DNS server address if required) (Optional) Call Waiting Disable Command (your telephone company can provide this value) To Configure for Internet Access: 1 Launch the Web browser on the computer that you connected to the LAN Modem. A welcome message appears. (If it does not, refer to “Troubleshooting,” page 6.) 2 Click Continue. The Dual 56K LAN Modem clock synchronizes itself to the date and time on your computer. The Set Password window appears. 3 (Optional) Enter a password in the Password field and in the Password (repeat) field to confirm. (Be sure to record this for future use.) A password guards access to the LAN Modem, and is recommended if you will set up dial-in access. If you do not want to set a password, leave blank. 4 Click Submit. The Set Country and Telephone Numbers window opens. 5 Choose your country from the drop-down list. 6 Enter your analog telephone number(s) including area code and click Continue. If you chose any country other than the United States, the LAN Modem resets and then returns you to the initial Welcome screen. Continue from Step 2, above. The ISP Wizard window appears. 7 Enter your ISP information. Choose any name for the ISP Name field. If you are not sure about the DNS server address, leave this field blank. 8 In the Dial Out Prefix field, enter the number you must dial to reach an outside line from your location, if applicable (for example, “9” for use with a PBX). 9 (Optional) In the Call Waiting Disable Command field, enter the value provided by your telephone company. This is used to prevent incoming calls from interfering with data calls. 10 Click Continue. A call is launched to your ISP, and a message confirming proper configuration appears. If the call to your ISP does not go through, refer to the troubleshooting section in the User Guide, located on the OfficeConnect Dual 56K LAN Modem Companion CD-ROM. 11 Click Continue. This completes the initial setup and will verify your configuration by placing a test call to the LAN Modem Support page on 3Com’s World Wide Web site. 12 Click Register to register your product. The ISP Wizard sets your LAN Modem configuration parameters to a typical default. If necessary, you can change these settings by returning to the LAN Modem’s configuration pages. To do so, enter http://3com.oc.lanmodem or http://192.168.1.1 in your browser. The connection made as a result of the ISP Wizard will automatically disconnect after seven minutes of inactivity. If you want to manually disconnect the call, access the LAN Modem configuration page and click Manual Calling. You can now connect up to three more computers (and/or printers) to your new LAN. If you wish to add more than four users, see “Connecting More Than Four Users,” page 5. To set up a connection to a Private Network or second ISP, refer to Chapters 6 and 7, respectively, in the User Guide. For documentation, firmware upgrades, and updated information about your LAN Modem, visit the LAN Modem Support page at any time at http://www.3com.com/support/docs/lanmodem/. 5 CONNECTING MORE THAN FOUR USERS After you have finished configuring your Dual 56K LAN Modem, you can connect an additional Ethernet hub or hubs to the Dual 56K LAN Modem to add up to 25 users. An example of a ten-user connection is shown. To connect an additional hub: 1 OfficeConnect Ethernet Hub 8 Insert one end of a 10BASE-T Ethernet cable (not included) into any available port on the back of the Dual 56K LAN Modem. 1 2 3 2 4 OfficeConnect Dual 56K LAN Modem 5 6 7 2 3 4 Insert the opposite end of the cable into one of the 10BASE-T Ethernet ports on the Ethernet hub.
