Administration Scenarios
This section describes a common configuration scenario as well as some common administration
scenarios where either the master or the backup Spectralink IP-DECT Server 6500/Spectralink Vir-
tual IP-DECT Server One fails.
Upgrading an Existing Spectralink IP-DECT/Virtual IP-DECT Server Solution into a
Redundant Solution
When ordering a Redundancy License to an existing running Spectralink IP-DECT/Virtual IP-DECT
Server solution, please remember to inform about the existing Spectralink IP-DECT/Virtual IP-
DECT Server ARI code and the NEW backup servers ARI code, to make sure that the master
redundancy license code is not generated to the wrong server. All handsets need to be re-sub-
scribed if this happens because the backup servers ARI code will be changed to match the master
server, and the whole redundant system refers to the ARI code of the master after the licenses have
activated. And if the two servers license codes have been generates incorrectly, the re-register of all
handsets has to be performed, and also a complete reconfiguration of the master server.
Temporary Failure on the Master Spectralink IP-DECT/Virtual IP-DECT Server
In the case where the master server fails due to loss of power, network connection etc., the backup
server will continue to provide service after a short failover time.
When the master server returns to operation, it will resume its normal operation in cooperation with
the backup server.
However, during the failover situation, it will not be possible to change any configuration settings,
add or remove users or change the subscription state of any handset.
Permanent Failure on the Master Spectralink IP-DECT/Virtual IP-DECT Server
If the master server has been damaged, lost or had its data erased, it will have to be replaced by the
backup server in order to return the system to normal operation mode. This is done by promoting the
backup server to ‘Master’ and the backup server will then assume the responsibilities of a master
server. The repaired or replaced master server can then be added as a new backup server, following
the above procedure of setting up a backup server.
Note:
Please be aware that if for some reason a repaired or replaced former master server is
reinstated as master, it should be done very carefully.
First, it must be configured as a backup server in order to get the current user data and
configuration from the acting master server (e.g. the original backup server).
Subsequently, when all data are replicated from the acting master to the original master,
the acting master can be demoted to backup server, and the acting backup server (e.g.
the original master) can be re-instated as master server.
