When subsequently mounting the FOS 100w on the PI box, make sure that the device has
been seated correctly and the unlocking tongue has clicked into place. Hereby the optical fiber
contact will be automatically established and provisioning will be carried out automatically,
too. After this (and with the necessary cables connected), the FOS 100w will be ready for use.
Since the FOS 100w is determined for continuous operation, it has no mains switch. For dis-
connection from the electricity grid, just remove the plug-in power supply unit. So the wall
power supply should always be easily accessible.
During operation, the FOS 100w is markedly warming up, but this operating temperature is
not dangerous at all. However, to provide for unimpeded heat dissipation, the FOS 100w must
not be installed into a fully closed casing, lacking of a sufficiently dimensioned breather hole.
For the same reason the device shall also be protected from intensive heating, caused e.g. by
heating appliances or direct sun radiation. Further, do not expose the modem to a very humid
or dusty environment.
