2 Ask your network administrator to reserve a new static IP-address to the origin Unite
CM that later on will be used as primary module. The IP-address must be reserved to
the module’s MAC address.
3 Ask your network administrator to reserve a static IP-address for the Unite CM to be
used as secondary module. The IP-address must be reserved to the module’s MAC
address.
4.12.1 Configure Redundancy in Unite CM
Do the following on the Unite CM to be used as primary module:
1 Click “Configuration” on the start page.
2 Select Other > Redundancy on the Configuration page.
NOTE: Before proceeding, make sure that the SD memory cards are inserted in both
modules.
3In the Virtual IP address text field, enter the virtual IP-address.
4In the Virtual netmask text field, enter the netmask of virtual IP-address.
5In the Secondary IP address text field, enter the IP-address of the secondary Unite
CM.
6In the Network monitor IP address text field, enter the IP-address of the equipment
to be used as network reference. The Unite CM will check that it has connection to the
network by sending ICMP (Internet Control Message Protocol) ping inquiries to this
equipment every second. If you do not want you use a network reference, set the IP-
address to 127.0.0.1.
NOTE: The network topology used in the system may have impact on which
equipment that should be used as network reference. See Appendix D.
7 Click "Activate".
8 Click "Reboot"
The Unite CM will now reboot and copy data from its internal flash memory to the SD
memory during the start up sequence. This can take up to 3 minutes. Note that Primary will
be stated in the GUI’s upper left corner when the module is up and running again.
IMPORTANT: When the redundancy has been activated, you must not remove the SD
memory cards since the modules will use these as data storage instead of
