Error cause 2.2
The PCU has an IP address that does not
belong to the network or has an invalid IP
address.
The TCU support is activated on the PCU (=
DHCP is enabled) and the PCU is active
DHCP-/DNS server (either as a result of the
DHCP SyncMode ON_MASTER or as a
result of the Sync priority - just the same as
the other server candidates and random
selection) - or the PCU is a DHCP client. As
a result of a software error or the actual
network configuration, the PCU cannot
obtain a valid IP address (e.g. '0 address').
Error cause 2.3
The PCU has an IP address that does not
belong to the network or has an invalid IP
address.
The TCU support is activated on the PCU (=
DHCP is enabled) and the PCU is active
DHCP-/DNS server (either as a result of the
DHCP SyncMode ON_MASTER or as a
result of the Sync priority - just the same as
the other server candidates and random
selection). The PCU is set with an incorrect
IP address and an incorrect IP range for the
IP addresses that can be dynamically
allocated. The PCU possibly changed from
DHCP standby to active server as the
computer with DHCP MASTER has failed or
been switched-off.
Remedy
Correctly set the network settings for the
system network in the Windows service
mode (set the fixed specified IP address and
subnet mask for the system network, use the
addressing mode, fixed IP address).
Execute the following actions using the
"System Network Center" program:
Connect the DHCP service to the
•
interface for the system network
Set the DHCP mode (TCU support,
•
DHCP SyncMode, address range of the
addresses that can be assigned)
Initiate DHCP clear
•
In addition, at the station with DHCP master
(DHCP SyncMode = ON_MASTER) a DHCP
clear should be initiated.
