Introduction

The EZ Connect Cable Modem provides high-speed Internet access over the same cable network system that brings cable TV service to the home. The data transmission rate on the cable connection is asymmetric, in that it provides a higher data rate in the downstream (receive) direction than in the upstream (transmit) direction. Asymmetric operation is ideal for typical home and small office use where files and information are downloaded more frequently than uploaded. This modem has a USB connection that provides plug-and-play installation and an Ethernet connection that allows you to connect up to 16 computers with the use of an Ethernet hub.

Mounting the Modem

The SMC8002CM-US comes with a slot-in stand with which it may be mounted vertically or horizontally. To do this, simply slide the modem onto the stand with the flanges provided on the base or the side. The two mounting options are illustrated below.

System Requirements

The SMC8002CM-US requires the following PC features to operate:

  • For USB connection:
    – A PC equipped with a USB port
    – Windows 98, Windows 98 SE, Windows Me or Windows 2000

  • For Ethernet Connection:
    – A PC with a 10/100 Mbps Ethernet adapter card installed
    – Windows 95 or later, Windows NT 4.0 or later

Connecting the Modem

Before connecting the EZ Connect Cable Modem, contact your cable service provider and check the following points:

  • Be sure that your service provider supplies a two-way data link.
  • Check that they have set up an Internet Access Account. To do this you will need to provide information that may include the product number and the modem MAC address. You will find this information on the label on the base of the modem.

The modem must be correctly connected to the service provider’s cable jack. If you are connecting both a TV and the modem to this outlet, you will need to use a splitter. The splitter duplicates the signal onto a second wire.

  1. Connect a 75-ohm coaxial TV cable between the splitter and the cable connector at the back of the modem. Ensure that you do not bend the center wire of the connector. Tighten both connectors by hand.

  2. Connect the modem to a surge-protected power source.

    – Check that the USB driver is correctly installed see “USB Installation for Windows 98, Window 2000 and Windows Me” on page 6.

  • For Ethernet connection:
    If the Link LED on the network adapter’s bracket does not light, check the following items.
    – Check that your computer is properly configured for TCP/IP see “Ethernet Installation for Windows” on page 6.
    – Make sure the UTP cable type complies with IEEE 802.3 Ethernet or IEEE 802.3u standards for the type of network you are using. Also, make sure cable lengths are within the requirements specified. (See “Making a Connection to the Ethernet Port” on page 7.)
    – Inspect all network cables and connections. Make sure the network cable is securely attached to the network adapter’s connector.
    – Make sure the correct network card driver is installed for your operating system. If necessary, try reinstalling the driver.
    – Make sure the computer and other network devices are receiving power. If you suspect a power outlet to be faulty, plug another device into it to verify that it is working.
    – If the network adapter’s speed or duplex mode has been configured manually, check that it matches that of the attached network device port. Note that it is recommended to set the adapter to auto-negotiation when installing the network driver.

Port and Cable Assignments

Caution: DO NOT plug a phone jack connector into any RJ-45 port. Use only twisted-pair cables with RJ-45 connectors that conform with FCC standards.
An Ethernet twisted-pair link segment requires two pairs of wires. Each wire pair is identified by two different colors. Each wire pair must be attached to the RJ-45 connector in a specific orientation detailed below.

The Ethernet port on the modem is an MDI-X port, which allows straight-through cable connections to PCs, and to hubs and switches with MDI ports. In straight-through cable, pins 1, 2, 3, and 6, at one end of the cable, are connected straight through to pins 1,2, 3, and 6 at the other end of the cable. For connection to hubs or switches which have MDI-X ports, a cross-over cable must be used.

Pin

| MDI-X Signal Name|

MDI Signal Name

---|---|---
1| Receive Data plus (RD+)| Transmit Data plus (TD+)
2| Receive Data minus (RD-)| Transmit Data minus (TD-)
3| Transmit Data plus (TD+)| Receive Data plus (RD+)
6| Transmit Data minus (TD-)| Receive Data minus (RD-)
4,5,7,8| Not used at 10 Mbps| Not used at 10 Mbps

Straight-Through Wiring

If the twisted-pair cable is to join two ports and only one of the ports has an internal crossover (MDI-X), the two pairs of wires must be straight- through.

Straight-Through RJ-45 Pin Assignments

End 1| End 2
1 (RD+)| 1 (TD+)
2 (RD-)| 2 (TD-)
3 (TD+)| 3 (RD+)
6 (TD-)| 6 (RD-)

Crossover Wiring

If the twisted-pair cable is to join two ports and either both ports are labeled with an “X” (MDI-X) or neither port is labeled with an “X” (MDI), a crossover must be implemented in the wiring.

Crossover RJ-45 Pin Assignments

End 1| End 2
1 (TD+)| 3 (RD+)
2 (TD-)| 6 (RD-)
3 (RD+)| 1 (TD+)
6 (RD-)| 2 (TD-)
