Use DNS server
You can manually enter the IP address of the DNS server under "DNS server". If you select
the "Automatically assign DNS server" option, the manual IP address is overwritten by an IP
address assigned by the DHCP server. This requires that the "Assign IP address
automatically (DHCP)" option is also selected.
Note
No connection between client and server
If you edit the configuration settings from an external PC, take the following into account:
The connection can be interrupted as soon as you enter a different IP address in "IP
address" or select the "Assign IP address automatically (DHCP)" option.
If you edit the configuration settings locally on the device, the connection to the configuration
settings will be maintained even if you change the IP address in the configuration settings.
If the "Assign IP address automatically (DHCP)" option is selected and no DHCP server is
available, no IP address will be assigned to the device. Communication between the server
and device is not possible.
 Open the configuration settings locally on the device, and assign an IP address that is not
already used in the network to the device.

You can also start remote configuration and open the "IP" tab to assign IP addresses for
one or more devices.
Alternatively, you can select the "Assign IP address automatically (DHCP)" option with
"Device name".
Note
A maximum of 240 characters is permitted. For connections via RDP, the device name will
be automatically truncated to the first 15 characters at logon.
Check valid settings
In the Start menu "Configuration> Information", the network settings that are currently valid
are always shown, regardless of whether they were assigned statically or dynamically. Use
this approach to check whether the change in the network settings was accepted or not.
