Tools for Installation

Power Considerations

Follow these precautions and recommendations when planning power connections to the Cisco uBR904 cable modem:

Check the power at your site before installation and during installation to ensure that you are receiving clean power. Install a power conditioner if necessary.

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

Tools for Installation

Each Cisco uBR904 cable modem chassis is fully assembled at the factory; no assembly is required. However, you will need the following tools and equipment to install the cable modem:

High-quality coaxial cable with at least 80% braid with foil

Coaxial cable crimping tool

Replacement coaxial cable connector ends

Ethernet straight-though cable with RJ-45 connectors (one included)

Console cable with RJ-45 connectors (light blue) (one included)

Tape measure (optional)

In addition, you might need the following external equipment:

CATV field strength meter (power meter)

CATV house amplifier

Portable, hand-held console terminal

Ethernet transceiver

Ethernet crossover cable with RJ-45 connectors (only if connecting the Cisco uBR904 cable modem to a hub)

Network interface card (if the computer at the installation site does not have one installed)
