Items You Need
f 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. t 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.
Note: For best performance, use high-quality RG-6 type coax cable and mini-
mize or eliminate splitters between the cable jack and the Cable Modem.
•Splitter (optional): provides an extra cable connection by splitting a sin-
gle outlet into two. You may need a splitter if you have a TV already con-
nected 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 nstructions for more details.

About this anual
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 pur-
chased, refer to the image at the left. The model number is on the label affixed to
the Cable Modem.
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 con-
nectors look like wide telephone connectors); you can purchase more cables if nec-
essary at a computer retailer. f 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 giga-
bit Ethernet (Gig-E), not regular CAT5 cable.

What About Security?
Having a high-speed, always-on connection to the nternet requires a certain
amount of responsibility to other nternet users—including the need to maintain a
reasonably secure system. While no system is 100% secure, you can use the fol-
lowing 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. n addi-
tion, avoid opening email containing attachments, or opening files sent
through chat rooms, whenever possible.
• nstall a virus checker and keep it updated.
• Avoid providing web or file-sharing services over your Cable Modem. Be-
sides certain vulnerability problems, most cable companies prohibit running
servers on consumer-level accounts and may suspend your account for vi-
olating 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 nternet users (some are shipped open by default). Crimi-
nals can take advantage of open proxies to hide their identity when break-
ing into other computers or sending spam. f you have an open proxy, your
cable company may suspend your account to protect the rest of the net-
work.
• f 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.
