What are the Requirements for Ethernet Network Devices?
How Many Ethernet Network Devices Can I Connect?
The gateway cable modem can support several Ethernet network devices using
either the Ethernet port on the back panel of the unit, or external Ethernet hubs
that must be purchased separately. The theoretical maximum number of Ethernet
network devices supported is by the gateway cable modem 253. However, under
normal circumstances, the number of devices connected should be a much lower
number. Contact your cable service provider for more information on the
maximum number of Ethernet network devices to connect to the gateway cable
modem in order 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
gateway 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 cable service provider or
consult the documentation for your Ethernet network devices for more
information.
Scientific-Atlanta recommends that you use CAT-5 Ethernet cables.
Do I Need to Configure the TCP/IP Protocol on My Computer?
In order 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, earlier in this guide, for detailed information on
configuring the TCP/IP protocol.
