Spectralink IP-DECT Server 200/400/6500 Installation and Configuration Guide

How This Works

The redundancy feature works as a two-step function, adding the redundancy feature and the load
balancing feature to the system. All users will be split up in two sections: a 50% of the users will be
registered on the master Spectralink IP-DECT Server 6500 and 50% of the users on the backup
server. This is indicated on Users > List Users > User List under Node (right side) by an M for
master server and an S for backup server (see image below):
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.
