CAUTION
Destruction of circuit packs in the event of a
short-circuit.
A short-circuit in the network element can cause destruction
of electronic components and thus malfunctioning of the
complete system.
You must therefore not handle objects such as a
screwdriver in the circuit pack area of the shelf.
CAUTION
Destruction of components due to test voltage of
incorrect polarity or too high.
The use of test voltages above 6 V DC for measurements on
circuit packs can cause destruction of components and thus
malfunctioning of the complete system.
Ensure that the test voltage does not exceed 6 V DC and
that the test equipment is connected with the correct
polarity.
CAUTION
Damage to system components under extreme
environmental conditions.
Extreme environmental conditions can damage system
components and cause malfunctioning.
Ensure that the "Climatic limits for the operation of
LambdaUnite MSS equipment" (1-35) are complied with
during operation.
