BEFORE YOU BEGIN 1 Introduction This guide provides all the information you need to use your Cable Modem TMX and an analog modem to dial into one-way Broadband Service Providers (BSPs). Not all cable companies and BSPs provide two-way service. In the event that you have a one-way cable provider or BSP, you need to use an analog modem to send data to the provider, and then receive data from the provider over the cable line using a cable modem like the TMX.
2 CHAPTER 1: BEFORE YOU BEGIN ■ ■ Plug and play operation ensures easy setup and installation 3Com’s extensive user support organizations and our 5-year limited warranty * Please note that the following factors affect the speeds you may experience: ■ Your computer equipment and configuration, including the speed of your processor, the amount of RAM on your system, and your available hard disk space.
Preparing Your Workspace ■ 3 The modem’s model number (located on a sticker on the bottom of the modem). MAC address: EA = __________________ Model number: 3CR292B-TR56 You should now contact your BSP and verify the following: ■ ■ ■ You have cable service to your home that supports cable modem access. If your BSP does not provide cable modem access, the 3Com U.S. Robotics Cable Modem TMX will not be able to communicate with your BSP’s Internet access service.
4 CHAPTER 1: BEFORE YOU BEGIN ■ ■ ■ Do not stack anything on top of the cable modem. (See the instructions on page 14 concerning stacking this modem with 3Com OfficeConnect products.) The temperature in the room where the cable modem will be operating should be between 0 and 40°C (32 and 104°F). Relative humidity should be between 5 and 95%, non-condensing. Familiarize yourself with all of the materials in this box.
Configuring the TCP/IP Protocol 5 the slot. If you are using wood screws, use #6 pan heads or equivalent. Configuring the TCP/IP Protocol NOTE: If you are using a Macintosh computer, turn to the instructions on page 7. Configuring the TCP/IP Protocol on a Windows PC You need to make sure that either an active Ethernet port, Ethernet Network Interface Card (NIC), or an active USB port and the TCP/IP communications protocol are installed on your system before you install your cable modem.
