Network topology and network configuration

The SCALANCE XB-000/XB-000G switches are typically in-
stalled with the stations to be connected in a control cabinet 
or control box. When configuring the network, it is necessary 
to observe the following boundary conditions:

• Length of the TP cable between two SCALANCE XB-000/ 

XB-000G switches 
- max. 100 m 
- max. 10 m via patch cable with TP Cord 
- max. 100 m via Industrial Ethernet FC Outlet RJ45, 

IE FC Standard Cable and TP Cord 

• Length of fiber-optic cables: 

- max. 3 km with Industrial Ethernet FO cables 

multimode

- max. 26 km with Industrial Ethernet FO cables 

singlemode

Diagnostics

The following information is indicated on the device by means 
of LEDs:

• Power
