CAUTION
Risk of fire due to overheating.
Inadequate heat dissipation can cause heat accumulation or even
a fire in the network element.
You must therefore ensure that:
• the fan unit is installed,
• the individual fans are not obstructed,
• the minimum separation is maintained between two shelves in a
rack (follow the installation instructions given in the
LambdaUnite
CAUTION
Destruction of the detector diodes caused by too high an input
power.
Connecting the output and input of optical circuit packs with a
transmit power in excess of -3 dBm over short distances will
cause the destruction of the detector diodes, as the input power is
then too high.
Use an optical attenuator pad of approx. 10 to 20 dB when
establishing connections over short distances for test purposes.
