Items You Need
If you are installing the Cable Modem yourself, make sure you have the following
items on hand before continuing:
•
Cable modem package: see What’s in the Box? for a list of items in the
package.
•
Coaxial cable (coax): as shown in the image to the left, this is a thin cable
with a connector on each end. It is the same kind of wire used to connect to
your television for cable TV. You can buy coax from any electronics retailer
and many discount stores; make sure it has connectors on both ends. There
are two types of connectors, slip-on and screw-on; the screw-on connectors
are best for use with your Cable Modem. The coax should be long enough
to reach from your Cable Modem to the nearest cable outlet.
Coax Cable
Note: For best performance, use high-quality RG-6 type coax cable and minimize or eliminate splitters between the cable jack and the Cable Modem.
•
Splitter (optional): provides an extra cable connection by splitting a single outlet into two. You may need a splitter if you have a TV already connected to the cable outlet that you want to use. You can buy a splitter from
any electronics retailer and most discount stores; you may also need a short
piece of coax cable (with connectors); use it to connect the splitter to the
cable outlet and then connect the Cable Modem and TV to the splitter.
Note: A splitter effectively cuts the signal in half and sends each half to its
two outputs. Using several splitters in a line may deteriorate the quality of
your television, telephone, and/or internet connection.
•
Wall-mount hardware (optional): if you want to wall-mount your Cable
Modem, you need to obtain two drywall anchors or wood screws. See the
Wall-Mount Template and Instructions for more details.

About this Manual
This manual covers all of the different CM900 models. Your model may not have all
of the capabilities outlined in this manual. To determine which model you have purchased, refer to the image at the left. The model number is on the label affixed to
the Cable Modem.
Model
Number
Ethernet Connection
Ethernet is a standard method of connecting two or more devices into a Local Area
Network (LAN).
Note:
To connect two or more computers to the Ethernet port, you will need a
hub or broadband router (available at computer retailers).
The Cable Modem package comes with a 6-foot (1.9m) Ethernet cable (the connectors look like wide telephone connectors); you can purchase more cables if necessary at a computer retailer. If you are connecting the Cable Modem directly to a
computer, or to an Ethernet hub or broadband router with a cross-over switch, ask
for Category 5e (CAT5e) straight-through cable. CAT5e cable is required for gigabit Ethernet (Gig-E), not regular CAT5 cable.

What About Security?
Having a high-speed, always-on connection to the Internet requires a certain
amount of responsibility to other Internet users—including the need to maintain a
reasonably secure system. While no system is 100% secure, you can use the following tips to enhance your system’s security:
•
Keep your operating system updated with the latest security patches. Run
the system update utility at least weekly.
•
Keep your email program updated with the latest security patches. In addition, avoid opening email containing attachments, or opening files sent
through chat rooms, whenever possible.
•
Install a virus checker and keep it updated.
•
Avoid providing web or file-sharing services over your Cable Modem. Besides certain vulnerability problems, most cable companies prohibit running
servers on consumer-level accounts and may suspend your account for violating your terms of service.
•
Use the cable company’s mail servers for sending email.
•
Avoid using proxy software unless you are certain that it is not open for
abuse by other Internet users (some are shipped open by default). Criminals can take advantage of open proxies to hide their identity when breaking into other computers or sending spam. If you have an open proxy, your
cable company may suspend your account to protect the rest of the network.
•
If you connect your Cable Modem to a wireless LAN, make sure you enable
security and encryption on the wireless hub (for the same reasons that you
should run only secured proxies). Consult the documentation and technical
support of the wireless equipment provider for help.

Troubleshooting
The Cable modem is plugged in, but the Power light is off.
Check all power connections. Is the power cord plugged in firmly at both
ends?
Model CM900S only: Is the rear panel power switch in the ON position?
If you plugged the power cord into a power strip, make sure the strip is
switched on.
Avoid using an outlet controlled by a wall switch, if possible.
Check the outlet by plugging in another device (such as a lamp).
Finally, check the fuse or circuit breaker panel.
I’m not getting on the Internet.
It may take over 30 minutes to establish a connection the first time you
power up your Cable Modem, especially when many people are online. Always leave your Cable Modem plugged into AC power and connected to the
cable system.
Check the front panel lights:
•
The Power and Online lights should be on.
•
The Link light should be either on or blinking.
•
If the Power light blinks for more than 30 minutes, call your cable company for assistance.
Check your cable connections. Connectors should be tight. The coax cable
should not be pinched, kinked, or bent sharply—any of these can cause a
break or short in the cable (you may have to replace the cable). If you have
one or more splitters between the Cable Modem and CATV outlet, remove
the splitters and connect the Cable Modem directly to the outlet.
Proceed to the Ethernet solution (next page) if necessary.

I’m not getting on the Internet. (Ethernet)
If you are using a hub, is the hub turned on?
Are you using the right type of Ethernet cable? Use the supplied cable for
direct connection to a computer; use a cross-over cable for connection to a
hub or home router.
Press the Reset button on the back of the Cable Modem.
I can get on the Internet, but everything is slow.
If the Web site you are visiting is very popular, that site may be having trouble servicing all the requests. If other sites download quickly, wait for a few
minutes and try again. Usage during peak hours may also affect the connection speed.
If your Cable Modem is connected to a LAN (Local Area Network), either directly or through a firewall, other communications on the LAN may slow
down your connection.
To test your network speed, try an online test such as

Glossary
The following is a list of common cable and networking terms.
Category 5e (Cat5e)
A high-quality type of cable, used for gigabit Ethernet (1000BaseT) connections. When purchasing Ethernet cables, always look for Category 5e cable.
Coaxial cable (coax)
A thin wire, used to connect your television and Cable Modem to the cable
TV system. You can buy coax from any electronics retailer and many discount stores.
CPE
Customer Premise Equipment. This is the equipment that is plugged in to the
cable modem; typically a computer, hub, or router.
Cross-over
An Ethernet cable used to connect two hubs (or a hub and a cable modem)
together. Also, some Ethernet hubs may have built-in cross-over on one or
more ports (which eliminates the need for a cross-over cable).
DHCP
Dynamic Host Configuration Protocol. An IP protocol used to provide an IP
address and location of services (such as DNS and TFTP) needed by a device
connecting to the network. DHCP allows the cable company to configure your
computer’s networking software for you.
DNS
Domain Name Service (Server). An IP service that associates a domain
name (such as www.example.com) with an IP address.
Downstream
In an HFC network, the direction from the head-end to the subscriber. Some
older cable documentation may refer to this as the forward path.

DOCSIS
Data Over Cable System Interface Specification. The interoperability standards used for data communications equipment on an HFC network.
EMTA
Embedded Multimedia Terminal Adapter. An MTA device that is integrated
with a cable modem.
Ethernet
A standard method of connecting two or more computers into a Local Area
Network (LAN).
Euro-DOCSIS
The European version of DOCSIS.
Event
An informational message used for monitoring network status.
F-connector
The type of connector used on coax cable. There are two common types of
F-connector, slip-on and screw-on. Use coax with screw-on connectors for
connecting your Cable Modem.
Gateway
The device, usually a router, that connects devices on a given IP subnet to
other IP subnets.
Headend
The “central office” in an HFC network. The headend houses both video and
data equipment. In larger cable networks, a “master” headend often feeds
several “remote” headends to provide distributed services.
HTTP
HyperText Transfer Protocol.
Hub
A box with several Ethernet connectors. Ethernet hubs provide a common
point of contact for all connected devices.

IP address
A number assigned to your computer by your cable company, used to identify your computer to other systems on the Internet.
ISDN
Integrated Services Digital Network. A digital telephony standard that provides communication speeds about twice as fast as standard dialup.
LAN
Local Area Network. A network that allows computers in a single location
(such as a building) to communicate with one another.
LED
Light Emitting Diode. A semi-conductor diode that emits light when current
is passed through it.
MAC address
A number that uniquely identifies any device connected to a network. Your
cable company uses your Cable Modem’s MAC address to authorize access
to the Internet. The MAC address is printed on a label on the bottom of your
Cable Modem.
Protocol
A set of rules and formats that determines the communication behavior of
network entities at a given layer.
Proxy
A device or program that stands in between a server (for example, a web
site) and a client (your browser), providing a way to relieve some of the
burden from the server. For example, your cable company may have a web
proxy that keeps copies of popular web pages; the proxy can send you those
pages instead of fetching them directly from the web site, resulting in faster
page loading and less network congestion.
RF
Abbreviation for Radio Frequency. Some literature refers to coax as “RF
cable” and the connectors as “RF connectors.”

A standard 8-conductor modular connector, commonly used on Ethernet
cable. An RJ-45 connector looks like a wide RJ-11 (telephone) connector.
Splitter
A small box with three cable connectors: one input and two outputs. You
may need a splitter if you have a TV already connected to the cable outlet
that you want to use for your Cable Modem. You can buy a splitter from any
electronics retailer and most discount stores.
Switched outlet
A power outlet that may be turned on and off using a wall switch. Usually
intended for lamps. Avoid plugging your computer or Cable Modem into a
switched outlet to avoid disruptions.
TCP/IP
