settings.
Factory default reset –removes all overrides made to the cable modem’s factory default
configuration and returns the cable modem to its original factory default settings.
The number of seconds you press the reset button determines which reset operation is
performed. To protect against accidental resets, the reset button is recessed on the cable
modem rear panel.
Note: You can also reset the cable modem and retain its current configuration settings using
the RESET method described under “Configuring Security Settings” on page 41.
To use the reset button to perform a software or factory default reset:
1. Leave power plugged into the cable modem.
2. Find the reset button at the top of the back panel, then use a thin object to press and hold
the reset button as follows:
–To perform a software reset, press the reset button for at least 10 seconds.
–To perform a factory default reset, press the reset button for at least 15 seconds.
3. Release the reset button.

2Installing the Cable Modem
This chapter describes how to install your D3CM1604 Cable Modem. The topics covered in
this chapter are:
Finding a Suitable Location (page 18)
Connecting to the LAN (page 19)
Connecting the WAN (page 20)
Powering on the Cable Modem (page 20)

Installing the Cable Modem
18
D3CM1604 DOCSIS 3.0 Cable Modem Administrator Manual
Finding a Suitable Location
Your D3CM1604 Cable Modem can be installed in any location with access to the cable
network. All cables connect to the rear panel of the cable modem for better organization and
utility. The LED indicators on the front panel are easily visible to show network activity and
status.
For optimum performance, the location you choose should:
Be close to a working AC power outlet when powering the cable modem using AC
power.
Allow at least one foot of space around the sides and top of the cable modem to provide
sufficient air flow around the device.
Not expose the cable modem to a dusty or wet environment.
Be an elevated location such as a high shelf, keeping the number of walls and ceilings
between the cable modem and your other devices to a minimum.
Be away from electrical devices that are potential sources of interference, such as ceiling
fans, home security systems, microwaves, or the base for a cordless phone.
Be away from any large metal surfaces, such as a solid metal door or aluminum studs.
Large expanses of other materials such as glass, insulated walls, fish tanks, mirrors,
brick, and concrete can also affect your signal.
Should allow the cable modem to connect to an AC outlet that is not controlled by a wall
switch.

Installing the Cable Modem

D3CM1604 DOCSIS 3.0 Cable Modem Administrator Manual
Connecting to the LAN
Using an Ethernet LAN cable, you can connect the cable modem to a desktop computer,
notebook, hub, or switch. The cable modem supports auto-MDI/MDIX, so you can use either
a standard straight-through or crossover Ethernet cable.
1. Connect either end of an Ethernet cable to the LAN port on the rear panel of the cable
modem (see Figure 2-1).
Figure 2-1. Connecting to the Ethernet Port on the Cable Modem Rear Panel
2. Connect the other end of the cable to your computer’s network-interface card (NIC) or to
another network device (see Figure 2-2).
Figure 2-2. Connecting the Cable Modem to the a Laptop or Desktop Computer

Installing the Cable Modem
20
D3CM1604 DOCSIS 3.0 Cable Modem Administrator Manual
Connecting the WAN
To connect the cable modem to a Wide Area Network (WAN) interface:
1. Connect a coaxial cable to the port labeled CABLE on the rear panel of the cable modem
from a cable port in your home or office (see Figure 1-3 on page 15). Use only
manufactured coaxial patch cables with F-type connectors at both ends for all connections.
2. Hand-tighten the connectors to secure the connection.
3. If the modem was not installed by your Internet Service Provider (ISP) or is replacing
another cable modem, contact your ISP to register the cable modem. If the modem is not
registered with your ISP, it cannot connect to the cable network system.
Powering on the Cable Modem
After making your connections, use the following procedure to power on the cable modem:
1. Connect the supplied power cord to the power port on the rear panel of the cable modem
(see Figure 1-3 on page 15).
2. Connect the other end of the power adapter to a working power outlet. The cable modem
powers on automatically, the POWER LED on the front panel goes ON, and the other front
panel LEDs show the cable modem’s status (see “Table 1-1”on page 14).
WARNING: Only use the power supply supplied with the cable modem. Using a different
power supply can damage the cable modem and void the warranty.
