the internal flash memory. The Unite CM will continue to use the SD memory
card as data storage even if the redundancy is deactivated.
When the data has been copied, the primary Unite CM sends configuration settings to the
secondary Unite CM that in turn reboots to apply the settings. After the reboot, the data will
be synchronized with the secondary Unite CM’s SD memory card. It can take up to one hour
to synchronize all data to a SD memory card with 1 GB capacity the first time. During this
time, the primary Unite CM is fully operational.
The LEDs on each Unite CM indicate the status of the synchronization.
Figure 33. LEDs showing the status of synchronization.
It is also possible to view the synchronization status via the GUI, see figure 34 and figure 35
on page 62. Use the virtual IP-address to access the active module and the static IP-address
to access the standby module.
