Initial assignment of an IP address 
Configuration options  
An initial IP address for an IE switch cannot be assigned using Web Based Management or 
the Command Line Interface because these configuration tools require that an IP address 
already exists. 
The following options are available to assign an IP address to an unconfigured device 
currently without an IP address: 
●  By DHCP 
●  With the STEP 7 configuration tool 
●  With the NCM PC configuration tool 
●  With the Primary Setup Tool (PST) configuration tool 
You will find the PST on the Internet pages of Siemens Industry Online Support under the 
following entry ID 19440762 
(http://support.automation.siemens.com/WW/view/en/19440762
). 
 
Note 
As of firmware version 
5.1.0 (SCALANCE X-200) or 5.2.0 (SCALANCE X-200IRT), you 
need to use PST version 4.2 or higher. Older versions of the PST (4.1 and older) are no 
longer compatible.
 
For more detailed information on using the configuration tools, refer to the relevant manuals. 
 
Note

switch, the IP 
address, subnet mask and gateway are assigned automatically when the
