Mean time between failure (MTBF)
The value in the following table applies to the basic device without media modules.
MTBF > 15 years
1)
1)
This value applies at 40 °C.
In the calculation of the MTBF of a modular switch, the standard parts count applies; in other
words, the reciprocals of all component failure rates are added.
The reciprocal of this total id the MTBF of the entire assembly.
