Never touch any electrical elements with bare hands.
To avoid potential shock hazards:
Do not carry out any installation, maintenance, or (re)configuration work during a
thunderstorm.
Do not connect or disconnect any power cables during a thunderstorm.
For installation in a Hot-Plug system, observe the safety instructions specific to
this system. Read the relevant documentation.
NOTE: Electrical installations must comply with the safety regulations of the country in
which they are operated.
WARNING: Laser Light!
Laser light from fiber-optic transmission cables and components can damage your
eyes.
The laser components on the network adapter are Class 1 laser components. Class 1
lasers are considered incapable of producing damaging radiation levels during normal
operation or maintenance and is, therefore, determined to be eye safe.
To avoid damaging your eyes and to continue safe operation in case of abnormal cir-
cumstances:
Never look directly into the outlets of fiber-optic cables or fiber-optic transmission
components with unprotected eyes!
Never allow fiber-optic transmission paths to operate until all the connections
have been made.
Always fit protective plugs to any unused ports on the switch or the network
adapter.
CAUTION: Radiation!
The use of controls or adjustments or performance of procedures other than those
specified herein may result in hazardous radiation exposure.
