Prestige 941 Cable Modem
Troubleshooting 2-4
2.4 Configuration Overview
The Prestige 941 cable modem is configured automatically using a configuration file generated by the cable
modem operator and delivered by the cable headend. The headend provides a path to the Prestige 941 cable
modem for both the DHCP server and PC address assignment.
The personal computer(s) connected the cable modem must be configured for Internet Protocol (IP). In
addition, your cable service provider must have a correctly configured Dynamic Hierarchical Control
Protocol (DHCP) server and EIA downstream channel. Using DHCP, headend assigns an IP address to
your cable modem each time you connect to the network. The IP address identifies the computer on the
network and enables the headend to route data to and from your computer.
When the cable modem is installed, the connected computer is configured for IP and has DHCP services
enabled, and communication to the headend is established, the headend downloads configuration
information to the cable modem. The initial configuration connection to the headend can take several
minutes.
2.5 Additional Installation Requirements
In addition to the contents of your package, there are other hardware and software requirements you need
before you can install and use your Prestige. These requirements include:
1. A computer with an Ethernet NIC (Network Interface Card) installed.
2. An ISP account.
After the Prestige is properly set up, you can make future changes to the configuration through telnet
connections.
2.6 Stacking ZyXEL Cable Modems
Your Prestige has legs that fit together for sturdy stacking. You should not stack more than four cable
modems for maximum stack stability.
