Always disconnect a device from its power source before you clean it.
■
If your SuperStack 3 NBX Call Processor is equipped with a redundant
power supply, you must disconnect both power cords.
CAUTION: Each of the two power supply units in the redundant
■
model has its own overcurrent protection device which operates
independently. That is, the overcurrent device for one power supply
does not protect the second power supply. You must connect both AC
power cords to the redundant model to provide power to both of the
power supplies.
Do not disassemble components of the system. If you suspect that a
■
card, chassis, or telephone is defective, call a service representative.
Do not use this product near water. Do not install the call processor,
■
the chassis, or a telephone in a damp area, such as a basement.
Never cover or block the ventilation holes on the chassis or
■
telephones. Proper ventilation is required to ensure normal operation
of each component and to avoid component failures.
WARNING: Never push objects into ventilation holes on the chassis or
■
telephone. Electrical voltages in system components can cause bodily
harm.
Do not use the telephone during an electrical storm. Lightning poses
■
a remote risk of electric shock through any telephone system.
Never use a telephone that is near the source of a gas leak to report
■
the leak.
Both the NBX 100 and the SuperStack 3 NBX Call Processors are
■
equipped with a three-prong grounding plug. Do not defeat the
protection offered by the plug by clipping the grounding prong or by
using an adapter to connect the system to a two-wire power source.
Do not staple the NBX power cord or otherwise attach it to building
■
surfaces.
Do not use any AC power converter on a 3Com Basic Telephone,
■
Business Telephone, or Attendant Console other than the one that is
shipped with the device. On the Model 3102 Business Telephone and
Model 3101 Basic Telephone, the power converter is an optional
component.
