The users will not always be on the same system. After a reboot of the Spectralink IP-DECT Servers
some of the users may have changed servers, there is no option to connect a specific user to a spe-
cific server, this is done randomly by the system.
Both servers need to have the same licenses installed, because both servers are acting as the same
server with one configuration and the backup server is a load balancing server combined with the
redundancy feature.
When a failure is discovered by the system, users, base stations and media resources are switched
automatically to the “remaining” server. This means that servers, media resources and IP-DECT
base stations MUST run the same firmware version.
Note:
In case you need to firmware upgrade to minimize downtime, update Spectralink IP-
DECT Base Stations, Spectralink DECT Media Resources and Spectralink IP-DECT
Servers BEFORE rebooting any of them. This will ensure that no older firmware will try to
connect to newer firmware. Also make sure that licenses loaded on to the master server
are also loaded on to the backup server, or the system will not work.
Configuring Redundancy

Not relevant to the Spectralink IP-DECT Server 400.
This section describes how to configure a redundant server solution:
l
Configuration of the redundancy feature requires the acquisition of redundancy licenses.

Redundancy Licenses
In order to enable the redundancy features, a license code with the proper permissions must be
installed on both the master and the backup Spectralink IP-DECT Server 6500.
Note:
If a license is installed on the master Spectralink IP-DECT Server 6500, a corresponding
license must be installed on the backup Spectralink IP-DECT Server 6500.
For example, if a 500 user license is installed on the master, a 500 user license must be installed on
the backup as well.
l
License required on the master:
1407 5250 – Software license for master Spectralink IP-DECT Server 6500 redundancy.
When ordering this license, please inform about the ARI code of the Spectralink IP-DECT
Server 6500 selected as master.
