• Construction of electrical and optical Industrial Ethernet line or star topologies
• Use of uncrossed connecting leads is possible due to integrated auto-crossover function of the ports
• Power supply of Power-over-Ethernet-capable terminal equipment via the data line for SCALANCE X108PoE
• Isolation of the load due to integrated switch functions
• Easy network configuration and network expansion;
  no limitation of the expansion of the network when switches of the SCALANCE X-100 product line are cascaded

Network topology and network configuration

The SCALANCE X-100 switches are typically installed with the stations to be connected in a control cabinet. They can be mixed electrically and optically in star and line topologies.

When configuring the network, it is necessary to observe the following boundary conditions:

• Length of the TP cable between SCALANCE X switches:
  • Max. 100 m with Industrial Ethernet FastConnect products
• Length of the TP cable between SCALANCE X switch and Power-over-Ethernet terminal equipment:
  • Max. 100 m with Industrial Ethernet FastConnect products
• Length of the fiber-optic cables:
  • Max. 5 km with Industrial Ethernet glass fiber-optic cables

Diagnostics

The following information is displayed by LEDs on site:

• Power
• Port status
• Data traffic

The Industrial Ethernet switches of the SCALANCE X-100 line can also be monitored over the floating signaling contact.
