Note
Regardless of the degree of protection of the casing, the electrical and optical
ports are always sensitive to
– mechanical damage
– damage caused by electrostatic contact discharge
– contamination by dust and fluids
Close unused ports with the supplied dust protection caps. Remove these caps
only immediately before connecting up the cables to the ports.
