What Are the Requirements for Ethernet Network Devices?

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.

Note:

Scientific Atlanta recommends that you use CAT-5 Ethernet cables.

Do I Need to Configure the TCP/IP Protocol on My Computer?

For you to use Ethernet network devices on your network, you must have the
TCP/IP protocol properly configured on your PC. Refer to

How Do I Configure

TCP/IP Protocol?

(on page 13), for detailed information on configuring the TCP/IP

protocol.
