ADMONISHMENTS
Important safety admonishments are used throughout this manual to warn of possible hazards
to persons or equipment. An admonishment identifies a possible hazard and then explains
what may happen if the hazard is not avoided. The admonishments — in the form of Dangers,
Warnings, and Cautions — must be followed at all times. These warnings are flagged by use
of the triangular alert icon (seen below), and are listed in descending order of severity of
injury or damage and likelihood of occurrence.
Danger: Danger is used to indicate the presence of a hazard that will cause severe personal
injury, death, or substantial property damage if the hazard is not avoided.
Warning: Warning is used to indicate the presence of a hazard that can cause severe
personal injury, death, or substantial property damage if the hazard is not avoided.
Caution: Caution is used to indicate the presence of a hazard that will or can cause minor
personal injury or property damage if the hazard is not avoided.
GENERAL SAFETY PRECAUTIONS
Danger: To avoid electric shock, be careful when working near HDSL loop connections or
telecommunications circuits. An electrical potential of ±130 volts exists on HDSL loop
connections and telecommunications circuits. Coming in contact with this high electrical
potential will result in death or severe personal injury.
Danger: Do not look into the ends of any optical fiber, or look directly into the module fiber
connectors. Exposure to invisible laser radiation may result, which can damage the retina of
the eye. An optical power meter should be used to verify active fibers.
Warning: To prevent electrical shock, never install telephone equipment in a wet location or
during a lightning storm. When installing or modifying telephone lines, disconnect lines on
the network side before working with uninsulated lines or terminals.
Caution: Electronic modules can be damaged by electrostatic discharge (ESD). Before
handling modules, wear an anti-static discharge wrist strap to prevent damage to electronic
components. Place modules in anti-static packing material when transporting or storing.
When working on modules, always place them on an approved anti-static mat that is
electrically grounded.
