2 Enter the secondary module using the virtual IP-address. Note that Secondary is

stated in the upper left corner indicating that this module currently is the active

module.

3 Select Status > Active Faults on the Configuration page. The log shows for example

that the secondary module is active and that the primary module has failed. Other

faults might also be shown.

4 Perform an action to ensure that the active module works properly. For example send

a message to a handset to check if it receives the message.

5 Connect the primary module and check if the secondary module starts to synchronize

with the primary module. A completed synchronization is indicated as follows;

• On the secondary module; the Status LED and the Power LED will be steady blue

as long the module acts as an active module.

• On the primary module; the Status LED is turned off and the Power LED will still

flash blue as long the module acts as a standby module.

• The synchronization status on both modules will be changed to Data in sync when

the data is synchronized.

After the test, it is recommended to switch back to the primary module again. See 4.12.5

Fallback to the Primary Unite CM on page 63.

4.12.4 Restrictions on an Active Secondary Module

A secondary module that has become active, has redistricted functionality as follows:

• The secondary module can only be up and running as active module for 30 days without

a repaired primary module connected. Note: If you for example shut down the secondary

module day 10, it can still use the remaining twenty days when it is started again. If the

repaired primary module is not connected within 30 days, the secondary module will

fallback as a standby module.

• It is not possible to disable the redundancy

• It is not possible to use the Troubleshoot mode

• It is not possible to perform a backup restore

• It is not possible to add a license

• It is not possible to run the Wizard

• It is not possible to activate the Demonstration Mode.

4.12.5 Fallback to the Primary Unite CM

When a secondary module has become an active module, it will only switch back to the

primary module if the secondary module failures. It is possible to manually switch back to

the primary module when it is in standby mode after repair.
