Interfaces, Displays and Operator Controls

Note

The autocrossover function of a TP/ITP port of the OSM/ESM is active only when it is set to the autonegotiation mode.

If this is not the case, it may be necessary to replace a straight-through cable with a crossover cable.

Please remember that even when using straight-through cables, an illegal loop can occur in the Ethernet network, caused, for example, by connecting two ports on an OSM/ESM. Such a loop can lead to network overload and network failure.
