1.2.2Star Structure

Functional Description

Star structures can be implemented with the SCALANCE X414-3E. The cascading depth and total span of a network are limited only by the signal propagation times of the communication connections.

Properties of a Star Structure

Each SCALANCE X414-3E communicates over a TP or FO cable with a central switch with which all other switches are also connected within a star structure. Communication is possible over the optical ports in slots 5, 6, or 7 or over the elec- trical ports in slots 5 and 9 to 11. With the fault mask, it is possible to monitor the port states using the signaling contact. In addition to connecting the switches to the central SCALANCE X414-3E, it is also possible to connect one or more end de- vices.
