T-Series Traffic Director Installation, Configuration and Administration Guide ix
Statement 34
Fiber Optic Safety Information, Statement 1
Caution:
To reduce the risk of electric shock or energy hazards:
• This equipment must be installed by trained service personnel in a
restricted-access location, as defined by the NEC and IEC 60950-1, First
Edition, The Standard for Safety of Information Technology Equipment.
• Connect the equipment to a properly grounded safety extra low voltage
(SELV) source. A SELV source is a secondary circuit that is designed so
that normal and single fault conditions do not cause the voltages to
exceed a safe level (60 V direct current).
• Incorporate a readily available approved and rated disconnect device in
the field wiring.
• See the specifications in the product documentation for the required
circuit-breaker rating for branch circuit overcurrent protection.
• Use copper wire conductors only. See the specifications in the product
documentation for the required wire size.
• See the specifications in the product documentation for the required
torque values for the wiring-terminal nuts.
Danger:
Hazardous Radiation
Fiber optic products use laser radiation with the potential to cause injury. Uncovered
ports may release this radiation. Avoid direct exposure to laser radiation. Do not stare
into the beam, and do not view directly with optical instruments. Do not remove any
protective shields on fiber optic transceiver modules.
