Factory default settings

Meaning of the symbols:
Preconfiguration of the TCU
The TCU is configured as a DHCP client and primarily accepts IP addresses from SINUMERIK
components, from the DHCP server of such components that are inherent to SINUMERIK, for
example, an NCU at X120 or a PCU on the system network or from a default DHCP server. The
behavior of the TCU cannot be modified here.
A TCU executes a boot via the network. The boot server is the computer node from which the
TCU also obtains its IP address.
