Preparing for Installation
Safety
–
In other countries: International Electro-technical Commission (IEC) 364, part 1 through
part 7.
•
Ensure that the shield of the coaxial cable is connected to the grounding system of the residence or
building as close to the point of cable entry as practical. In the United States, the cable system must
be in accordance with Article 820-40 of the National Electric Code.
•
Keep the installation area clear and dust free during and after installation.
•
Keep tools and all components away from walk areas.
•
Do not wear loose clothing, jewelry (including rings and chains), or other items that could get
caught on the cable access router. Fasten your tie or scarf and roll up your sleeves.
•
Use only the power supply provided by Cisco to power the Cisco uBR905 cable access router.
•
Use only the power cord provided by Cisco or other grounding IEC 320 type power supply cord
acceptable to the local electrical authorities to connect the power supply to the power outlet. The
router ships with a three-wire electrical grounding-type plug which fits only into a grounding-type
power outlet. This is a safety feature. Equipment grounding should be in accordance with local and
national electrical codes.
Warning
Failure to properly ground the router—either by circumventing the three-wire
grounding-type plug or by using a power outlet that is improperly grounded—can create
a potentially hazardous electrical situation.
•
Operate the Cisco uBR905 cable access router in accordance with its marked electrical ratings and
product usage instructions.
•
Always unplug the power cable before installing or removing a cable access router.
•
Do not work on the system or connect or disconnect cables during periods of lightning activity.
Electrical
Follow these guidelines when working with electrical equipment:
•
Disconnect all power and external cables before installing or removing a cable access router.
Warning
Unplug the power cord before you work on a system that does not have an on/off switch.
•
Do not work alone when potentially hazardous conditions exist.
•
Never assume that power has been disconnected from a circuit; always check.
•
Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
•
Never install equipment that appears damaged.
•
Carefully examine your work area for possible hazards such as moist floors, ungrounded power
extension cables, and missing safety grounds.
In addition, follow these guidelines when working with equipment that is disconnected from a power
source, but still connected to cable wiring.
•
Never install coaxial wiring during a lightning storm.
•
Never install cable jacks in wet locations unless the jack is specifically designed for wet locations.
