Possible error causes and remedies
Remedy
A decision has to be made which computer should keep the IP address that has been
assigned twice. If it is the PCU, then
on the PCU, under network settings, this address should be again set as fixed IP address

Restart the system.
Error cause 2
This was preceded by replacing the PCU hardware.
As a result of the hardware replacement, in spite of the same settings of the new PCU, the
requested (set) IP address is still internally reserved for the previous hardware as this is an
inherent feature of the system. The PCU is either active or non-active DHCP server, however,
is operated in the synchronizing DHCP mode. As the address requested from the PCU is still
reserved, the PCU is allocated an address from the dynamic address range via DHCP.
Remedy
Perform the following steps:
Under network settings, on the PCU, set the required address again as fixed IP address in
•
the system network.
At the NCU/PCU, which runs in the DHCP synchronization mode ON_MASTER or is active
•
DHCP server, execute a 'Clear DHCP' (for an NCU using the sc command sc clear dhcp –
X120, for a PCU, using the "System Network Center" program).
Restart the system.

Error cause 3
An address that does not belong to the network has been configured for the PCU.
An address has been configured for the PCU, which does not match the network address in
the system network, and is therefore dynamically assigned an IP address from the active
server via DHCP. The PCU is not an active DHCP server, but is operated in the synchronizing
DHCP mode.
