Possibility of personal injury. The chassis does not contain main overcurrent
protection devices. The user must provide circuit breakers or fuses and
disconnects between the power source and the Alcatel-Lucent
1677 SONET Link. Each power feed from a source (-48 V dc and Return)
requires a 25-amp dc-rated fast-trip circuit breaker or fuse and disconnect.
Circuit breakers or fuses must meet applicable local and national electrical
safety codes and be approved for the intended application.
Possibility of personal injury. Make sure you connect the node to a -48 V dc
source that is electrically isolated from the ac source and is reliably
connected to earth ground.
Possibility of personal injury. For personal safety, make sure you connect
and secure the installation site's frame-ground (earth ground) wire to the
frame-ground terminal on the 1677 SONET Link before you connect any
other wires to the node.
Possibility of personal injury. A dc-power source provides high energy,
which can cause serious injury or equipment damage. Only Alcatel-Lucent
qualified personnel should connect the dc power to the Alcatel-Lucent
1677 SONET Link. To prevent serious injury or equipment damage, make
sure the power source cables are de-energized before you handle or connect
them to the node.
Verify that laser labels on equipment state that the system conforms
3.4
to all applicable standards of 21 CFR 1040.10. See figure
are no danger labels, call the Alcatel-Lucent Technical Assistance Center
(TAC).
The invisible infrared radiation emitted by the fiber-optic transmitter
3.5
can cause eye damage. Observe local office procedures and the following
dangers:
Possibility of personal injury. The use of controls and/or adjustments, or the
performance of procedures other than those specified herein may result in
hazardous infrared radiation exposure.
Possibility of personal injury. Laser infrared radiation is not in the visible
spectrum; therefore, it is not visible to the naked eye or with laser safety
glasses. Although it cannot be seen, laser radiation may be present.
