Be aware that the above operation is not recommended as it is possible for the Primary System to
move from one node to another if the Primary is reset.
Database Backup
Prior to setting up NetLink, a recovery database should be created for each system. This is used when you
wish to remove a system from NetLink.
From handset programming:
Create recovery database
Restore recovery database
Delete recovery database
All recovery databases on a particular GCD-CP10 will be lost if the system is defaulted.
Remove a NetLink Node
If it is required to remove a NetLink node from the network it should be deleted from the Primary System's
database.
From handset programming:
Delete system information
The system must be disconnected from the network before this command is executed.
