What’s In the Carton?

When you receive your gateway cable modem, you should check the equipment and accessories to verify that

each item is in the carton and that each item is undamaged. The carton contains the following items:

One Model DPR2320 or EPR2320

Gateway Cable Modem with

detachable antenna

One Ethernet cable (CAT5/RJ-45)

One power adapter with power cord

One USB cable

One CD-ROM containing the user’s

guide and the USB drivers

If any of these items are missing or damaged, please contact your cable service

provider for assistance.

You will need an optional cable signal splitter and additional standard RF coaxial

cables if you want to connect a VCR, a Digital Home Communications Terminal

(DHCT) or a set-top converter, or a TV to the same cable connection as your

cable modem.

Front Panel Description

The front panel of your cable modem provides status lights that indicate how well and at what state your cable

modem is operating. After the cable modem is successfully registered on the network, the POWER and CABLE

status indicators illuminate continuously to show that the cable modem is active and fully operational. See Front

Panel Status Indicator Functions, later in this guide, for more information on front panel status indicator

functions.

existing cable input connection to eliminate the need for an additional cable

outlet. There should be plenty of room to guide the cables away from the

modem and the PC without straining or crimping them.

•Airflow around the gateway cable modem should not be restricted.

•Choose a location that protects the gateway cable modem from accidental

disturbance or harm.

•Read this user’s guide thoroughly before you decide where to place your

gateway cable modem.
