8. All metallic telecommunication interfaces (traffic ports) should not leave the building
premises unless connected to telecommunication devices providing primary and
secondary protection, as applicable.
9. Do not use this product near water, for example, in a wet basement.
10. Do not place this product on an unstable cart, stand or table. The product may fall,
causing serious damage to the product.
11. Use caution when installing or modifying telecommunications lines.
12. Never install telecommunications wiring during a lightning storm.
13. Never install telecommunications connections in wet locations.
14. Never touch uninsulated telecommunications wires or terminals unless the
telecommunications line has been disconnected at the network interface.
15. Never touch uninsulated wiring or terminals carrying direct current or ringing current,
or leave this wiring exposed. Protect and tape uninsulated wiring and terminals to
avoid risk of fire, electric shock, and injury to service personnel.
16. Never push objects of any kind into this product through slots as they may touch
dangerous voltage points or short out parts that could result in a risk of fire or electrical
shock. Never spill liquids of any kind on the product.
17. Slots and openings in the unit are provided for ventilation, to protect it from
overheating, and these openings must not be blocked or covered. This product should
not be placed in a built-in installation unless proper ventilation is provided.
18. To reduce the risk of an electrical shock, do not disassemble this product. Service
should be performed by trained personnel only. Opening or removing covers and/or
circuit boards may expose you to dangerous voltages or other risks. Incorrect
reassembly can cause electrical shock when the unit is subsequently used.
19. Some of the Alcatel-Lucent 1665 DMX Family hardware modules contain
FDA/CDRH Class IIIb/IEC Class 1M single-mode laser products that are enclosed
lightwave transmission systems. Under normal operating conditions, lightwave
transmission systems are completely enclosed; nonetheless, the following precautions
must be observed because of the potential for eye damage:
•
•
•
•
20. For a unit intended to be powered from -48 V dc voltage sources, read and understand
the following:

Do not disconnect any lightwave cable or splice and stare into the optical
connectors terminating the cables.
Lightwave/lightguide operations should not be performed by a technician who has
not satisfactorily completed an approved training course.
Do not use optical instruments such as an eye loupe to view a fiber or unterminated
connector.
