SMC8002CM Installation Guide

9

Physical Placement

Place the cable modem on a stable, flat surface such as a desktop, close to the CATV
cable drop connection and all devices to be connected. The surrounding areas of the
cable modem must remain unobstructed to ensure adequate airflow and to prevent the
unit from overheating.

Caution: Do not place the cable modem on an uneven or soft surface.

Connecting to the Cable System

Ø Verify that the cable modem is not connect ed to the power source. It will generate

installation difficulty if you power on the cable modem before connect RF coaxial
cable.

Ø Locate the RF coaxial cable from the CATV wall outlet.

Ø Install a cable splitter/directional coupler if it is needed to separate signals for TV

and PC usage.

Ø Connect the RF coaxial cable to the cable modem’s F-connector. Hand-tighten the

connector, making sure it is finger-tight.

Caution: Do not over-tighten the connector because doing so can break off the
connector.

Ø Make sure all other coaxial cable connectors and all intermediate splitters,

couplers, or ground blocks are securely tightened from the distribution tap to the
cable modem.

Note: Loose connectors inside the building or residence can cause intermittent

cable modem operation.

Caution: To ensure compliance with FCC limits, connection to the cable system
must be made with a high-quality, shielded cable. If the quality or general
condition of the coaxial cable is in question, it is recommended that you replace
the coaxial cable.

10

SMC8002CM Installation Guide

Verifying Power Requirements

The cable modem will only accept 10Vdc, 1.2A power. An external AC-to-DC power
adapter must be used to make the cable modem work properly. Only the power
adapter accompanying this cable modem should be use d. Use of any other adapter
will void the product warranty.

We recommend that you follow these precautions:

Ø Verify the power adapter’s power plug is the same as that of your local power

outlet. If not, do not use it and ask your service provider for a replacement.

Ø If you are plugging the cable modem into an Uninterruptible Power Supply (UPS),

verify that the total power and current requirements used by all devices plugged
into the UPS are within the maximum limits of the UPS.

Ø Install proper grounding to avoid damage from lightning and power surges. If

using a North American (NEMA 5-15P) plug, you must plug the unit into a
three-lead receptacle to ensure proper grounding.

Warning: Never remove the ground conductor or operate the equipment in the
absence of a suitably installed ground conductor. Contact the appropriate
electrical inspection authority or an electrician if you are uncertain that suitable
grounding is available.

Ø Ensure that a proper fuse or circuit breaker is used on the phase conductors (all

current-carrying conductors providing power to the device).

Ø Do not work on the system, connecting or disconnecting any cables (Ethernet,

cable, or power) during periods of lightning activity. The possibility of serious
physical injury exists if lightning should strike and travel through those cables.
