What are the Requirements for Ethernet Network Devices?
 
How Many Ethernet Network Devices Can I Connect? 
The cable modem gateway can support several Ethernet network devices using 
either the 4 Ethernet ports 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 cable modem gateway 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 cable modem gateway in order to maintain optimal network performance. 
What are the Wiring Requirements for Ethernet Networking? 
Although the cable modem gateway 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 10/100 
BaseT CAT-5 Ethernet hubs is 382 feet (100 meters). Scientific-Atlanta 
recommends that you use CAT-5 Ethernet cables.  
A number of factors can impact the practical limit of the network. Contact your 
cable service provider or consult the documentation for your Ethernet network 
devices for more information.  
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.
