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: This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser
radiation can seriously damage the retina of the eye. Do not look into the ends of any optical
fiber. Do not look directly into the optical transceiver of any digital unit or exposure to laser
radiation may result. An optical power meter should be used to verify active fibers. A
protective cap or hood MUST be immediately placed over any radiating transceiver or optical
fiber connector to avoid the potential of dangerous amounts of radiation exposure. This
practice also prevents dirt particles from entering the adapter or connector.
Danger: Do not look into the ends of any optical fiber. Exposure to laser radiation may
result. Do not assume laser power is turned-off or the fiber is disconnected at the other end.
Danger: Wet conditions increase the potential for receiving an electrical shock when
installing or using electrically-powered equipment. To prevent electrical shock, never install
or use electrical equipment in a wet location or during a lightning storm.
Warning: The Digital Chassis and other accessory components are powered by 48 VDC
power which is supplied over customer-provided wiring. To prevent electrical shock when
installing or modifying the power wiring, disconnect the wiring at the power source before
working with uninsulated wires or terminals.
