Safety messages
Safety messages are an important part of the technical documentation. The messages alert you to
hazards to personnel and equipment and provide guidance for the safe operation of your equipment.
Failure to comply with the safety messages could result in equipment damage and personal injury.
Following are the most common types of safety messages.
Warning:
Installation must be performed by qualified service personnel only. Read and follow all warning
notices and instructions marked on the product or included in the documentation.
Voltage:
This equipment relies on the building's installation for overcurrent protection. Ensure that a fuse
or circuit breaker no larger than 120 VAC/20 A or 240 VAC/16 A is used on the phase
conductors.
Caution:
This device is a Class A product. In a domestic environment, this device can cause radio
interference, in which case the user may be required to take appropriate measures.
Caution:
When mounting this device in a rack, do not stack units directly on top of one another in the
rack. Each unit must be secured to the rack with appropriate mounting brackets. Mounting
brackets are not designed to support multiple units.
Voltage:
Use only power cords that have a grounding path. Without a proper ground, a person who
touches the switch is in danger of receiving an electrical shock. Lack of a grounding path to the
switch can result in excessive emissions.
Warning:
Disconnecting the power cord is the only way to turn off power to this device. Always connect
the power cord in a location that can be reached quickly and safely in case of an emergency.
Warning:
Fiber optic equipment can emit laser or infrared light that can injure your eyes. Never look into
an optical fiber or connector port. Always assume that fiber optic cables are connected to a light
source.
