Getting Started
About Your New Cable Modem
The Touchstone C 300 Cable odem is a DOCSIS 1.1-compliant (and DOCSIS 2.0
A-TD A ready) cable modem with the following features:
• Speed: much faster than dialup or ISDN service
• Convenience: supports USB 1.1 and Ethernet; both can be used simulta-
neously
• Security: a Standby button lets you isolate connected computer(s) from
the Internet without shutting off the Cable odem
• Compatibility: supports tiered data services (if offered by your cable
company)
• Enhanced troubleshooting: a web-based interface lets you access Cable o-
dem status information from a computer connected to the Cable odem

tems You Need
If you are installing the Cable odem 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 picture to the left, this is a thin ca-
ble with a connector on each end. It is the same kind of wire used to connect
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 odem.) The coax should be
long enough to reach from your Cable odem to the nearest cable outlet.
ARRIS recommends using only high-quality RG-6 coax.
• 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 coaxial cable (with connectors); use it to connect the splitter to the
cable outlet and then connect the Cable odem and TV to the splitter.
• nformation packet : your cable company should furnish you with a packet
containing information about your service and how to set it up. Read this
information carefully and contact your cable company if you have any ques-
tions.

USB or Ethernet?
There are two ways to connect your computer (or other equipment) to the Cable
odem. The following will help you decide which is best for you:
USB
USB (Universal Serial Bus) is meant for connecting a variety of accessories, such
as keyboards, mice, printers, and communications devices (including cable mo-
dems) to a single PC. Use the USB connection if you have only one computer, and
the computer is using a Windows operating system (Windows 98 Second Edition or
later).
The Cable odem package comes with a 4-foot (1.2m) USB cable; you can pur-
chase a longer cable if necessary at a computer retailer. Ask for an USB A/B
cable —it has a long narrow connector on one end (to connect to the PC) and a
square connector on the other end (to connect to the Cable odem).
Ethernet
Ethernet is a standard method of connecting two or more computers into a Local
Area Network (LAN). Use the Ethernet connection if your PC does not use Windows,
or you want to share the Cable odem connection with several computers.
Note: To connect two or more computers to the Ethernet port, you need a hub
or broadband router (available at computer retailers).
The Cable odem package comes with a 4-foot (1.2m) Ethernet cable (the connec-
tors look like wide telephone connectors); you can purchase more cables if neces-
sary at a computer retailer. If you are connecting the Cable odem directly to a PC,
or to an Ethernet hub or broadband router with a cross-over switch, ask for
Category 5 (CAT5) straight-through cable. If you are connecting the Cable odem
to an Ethernet hub or broadband router without a crossover switch, ask for a Cat-
egory 5 crossover cable.
Both
If you have two or more computers, you can connect one computer to the Cable
odem’s USB port and one or more to the Ethernet port. To connect two or more
computers to the Ethernet port, you need a hub or broadband router (available at
computer retailers).

nstalling and Connecting Your Cable
Modem
Before you start, make sure that:
• The cable company has set up your account. You should have an information
packet that describes your service.
• The Cable odem serial number and AC address matches the number
shown in your information packet.
• Cable and power outlets are available near the chosen location.
Getting Service
If you purchased your ARRIS Cable odem through your local cable company, you
should already have everything you need to connect and use it.
If you have not already arranged for high-speed Internet service from your cable
company, contact the cable company’s sales office.

Mounting the Cable Modem
You can either mount the Cable odem on a wall or place it on a desktop. For wall-
mount applications, you can mount the Cable odem with the indicators facing up-
ward (vertical) or to the size (horizontal).
Tools and Materials
ake sure you have the following tools and materials before proceeding:
• a wrench (for securing the coax connector)
• For wall-mount installations:
— screwdriver (flat-blade or Phillips, depending on what kind of screws you
use)
— wall-mount template (included with the Cable odem Quick Installation
Guide)
— transparent tape (for temporarily securing the mounting template to the
wall)
— for mounting on plywood or studs: two #8 x 38.1 mm (1.5 inches) self
tapping screws; the head diameter should be approximately 6 mm (0.25
inches)
— for mounting on drywall: two 1.5 inch (35mm or 40mm) anchor bolts
Location
Always position the Cable odem:
• within 1.3 m (4 feet) of an AC outlet. The power cord must reach the outlet
without stretching and without adding extension cords.
• near a cable outlet (to avoid long cable runs).
Note: When mounting the Cable odem on drywall, try to position the Cable
odem so the screws are fastened to a stud. This may prevent the Cable
odem from pulling out of the wall in the future.

nstructions
Wall-mounting instructions
1 Position the mounting template on the surface where you intend to mount
the Cable odem and secure in place with transparent tape.
2 Drill holes through the template in the specified locations for the mounting
screws. After drilling holes, remove the template from the surface.
3 Drive both of the screws (or anchor bolts) into the wall. Leave a gap of about
6 mm (0.250 inches) between the screw head and the wall.
4 Orient the Cable odem with the indicator lights facing up or right, as de-
sired. Slip both mounting slots (in the back of the Cable odem) over the
screws, then slide the case down until the narrow end of the keyhole slot
contacts the screw shaft.
5 Proceed to Connecting the Cable odem.
Desktop mounting instructions
6 Position the Cable odem so that:
• air flows freely around it
• the back faces the nearest wall
• it will not fall to the floor if bumped or moved
7 If you want to stand the Cable odem up on its side, pull the oval foot out
slightly, twist the foot (as shown), and place the Cable odem in the desired
location.
8 Proceed to Connecting the Cable odem.

Connecting the Cable Modem
1 Connect one end of the coaxial cable to the cable outlet or splitter, and the
other end to the Cable odem’s Cable connector. Tighten the connections
by hand, then tighten 1/8 turn with a wrench.
Note: Improperly tightened coaxial cable connectors can cause data errors,
making your connection slower.
2 Insert the plug from the AC adapter into the Power connector on the Cable
odem.
3 Insert the power cord into a convenient AC outlet.
The Power light on the front of the Cable Modem should light up, then start
flashing. See Troubleshooting if the Power light does not turn on.
4 After connecting the coax cable and power, proceed as needed:
•aking USB Connections
•aking Ethernet Connections
Note: Do not connect a single computer to both the Ethernet and USB ports.
Making USB Connections
5 Connect one end of the USB cable to the USB port on the computer, and the
other end to the USB port on the back of the Cable odem.
Your PC should detect the Cable Modem and begin installing the drivers. See
Installing US Drivers on Your PC for driver installation details.
Making Ethernet Connections
6 Connect one end of the Ethernet cable to the port on the back of the Cable
odem labeled “Ethernet 10/100,” and the other end to the Ethernet port
on a computer, hub, or broadband router.
Note: If you are connecting to a computer, use the Ethernet cable included
in the Cable odem package unless it is too short. Longer Ethernet cables
are available from any computer retailer.
