What Are the Requirements for Ethernet Network Devices? How Many Ethernet Network Devices Can I Connect? The Scientific Atlanta cable modem can support several Ethernet network devices using external Ethernet hubs that must be purchased separately. The theoretical maximum number of Ethernet network devices supported by the cable modem is 63. However, under normal circumstances, the number of devices connected should be a much lower number. Contact your service provider for more information on the maximum number of Ethernet network devices to connect to your cable modem to maintain optimal network performance. What Are the Wiring Requirements for Ethernet Networking? A number of factors can impact the practical limit of the network. Although the cable modem is designed to support several Ethernet network devices, it is important to view the characteristics of the entire network and not just each individual node. The theoretical distance between two 10/100BaseT CAT-5 Ethernet hubs is 382 feet (100 meters). Contact your service provider or consult the documentation for your Ethernet network devices for more information. The cable modem begins an automatic search to locate and sign on to the network. In some unusual circumstances, this process may take up to 5 minutes. The cable modem is ready for use when the ONLINE LED status indicator on the front panel stops blinking and illuminates continuously. Verify that all Ethernet network devices are working properly. Note: You will not be able to check the front panel LED status indicator on the cable modem until after one or more Ethernet network devices are connected to the cable modem. 5 6 7 4012160 Rev B 29 What Are the Requirements for USB Network Devices? What Are the Requirements for USB Network Devices? How Many USB Devices Can I Connect? You can connect one PC or other USB device to the USB port on the EMTA. What Are the Wiring Requirements? Scientific Atlanta recommends that you use the USB 1. 1 cable provided with your modem. Do I Need to Install USB Drivers on My Computer? To use USB network devices, you must have the correct USB drivers installed on your PC. (on page 24), for information on installing USB drivers. 30 4012160 Rev B How Do I Select and Place USB Network Devices? How Do I Select and Place USB Network Devices? You can use a large variety of USB network devices with your cable modem. These include desktop computers, laptop computers, devices with USB ports, and USB adapters. Contact your service provider or consult the documentation for your USB network devices for more information on selecting USB network devices. Where Is the Best Location for My USB Network Devices? You should work with your service provider to choose the best location for your USB network devices. Consider these recommendations: Location of two-way coaxial cable outlets Distance of the USB network devices from the cable modem Location of computers and other equipment from AC power outlets Ease of running USB cable to the USB network devices Now that you have selected a location for your USB network devices, the next step is to place and connect your USB network devices.
