Redundant System Configuration
Note:
Not relevant to the Spectralink IP-DECT Server 200/400.
This section describes the redundancy feature in the Spectralink IP-DECT Server 6500. You will find
a description of how to design, configure and administer a redundant Spectralink IP-DECT Server
6500 solution including a master and a backup server.
The redundancy feature of the Spectralink IP-DECT Server 6500 solution allows adding a backup
server to the system, offering both better availability and better performance due to load balancing.
By adding a backup server, the most critical failure point of the system is eliminated, allowing the sys-
tem to continue running and provide service to the users, even when a server fails. Any active calls or
sessions handled by the failed component will however be lost.
The redundancy feature is designed to be as non-intrusive as possible. Except for a few simple
redundancy options, configuration and administration of a redundant solution is not different from a
single server solution. All configurations are executed on the master server, and everything is presen-
ted in the same familiar menus. Configuration data and statistics are automatically propagated
between all the Spectralink IP-DECT Server 6500 entities, e.g. base stations, media resources and
server.
Note:
If a third party application is connected to the Spectralink IP-DECT Server 6500, e.g. a
messaging application or a nurse call application, this application must connect to the
master Spectralink IP-DECT Server 6500.
In case of a failure in the master server, the application will not be able to communicate
with the handsets unless the application is designed for redundancy.
This is further described in the XML-RPC SDK document. To obtain this document go to

Firmware Compatibility (Redundancy)
For using a redundant server solution, it is required that the backup Spectralink IP-DECT Server has
the same firmware revision and licensed features as the master Spectralink IP-DECT Server to be
able to connect to the master.
In case a backup server tries to connect with a different firmware version or other licensed features
than the master server, an error message will be logged and the backup server will be rejected.

Note:
Provisioning of server firmware it not possible in a redundant setup.
