Firmware Compatibility (Redundancy)
For using a redundant server solution, it is required that the backup Spectralink IP-DECT/Virtual IP-
DECT Server has the same firmware revision and licensed features as the master Spectralink IP-
DECT/Virtual 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.
Design of Redundant Server Solution
This section describes how to design a redundant Spectralink IP-DECT Server 6500/Spectralink Vir-
tual IP-DECT Server One solution.
Designing a redundant Spectralink IP-DECT/Virtual IP-DECT Server solution is very similar to
designing any other redundant network service. In a redundant Spectralink IP-DECT/Virtual IP-
DECT Server solution, the servers should be connected to separate switches, power groups etc.
Below is an example design of a redundant Spectralink IP-DECT Server 6500 solution including a
master Spectralink IP-DECT Server 6500 and a redundant backup Spectralink IP-DECT Server.
Note:
l
Use separate switches, power groups and servers in a redundant setup.
l
Master server and backup server must have same firmware version.
l
When upgrading firmware on base stations, servers and media resources, only
reboot when all devices have been upgraded.
l
Keep-alive packets using TCP on port 50017 are sent between the master server
and backup server. Network administrators should make sure that this port is
open.
