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 fails.
Upgrading an Existing Spectralink IP-DECT Server 6500 Solution into a Redund-
ant Solution
When ordering a Redundancy License to an existing running Spectralink IP-DECT Server 6500 solu-
tion, please remember to inform about the existing Spectralink IP-DECT Server 6500 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-subscribed if this happens because the
backup servers ARI code will be changed to match the master server, and the whole redundant sys-
tem 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 Server 6500
In the case where the master Spectralink IP-DECT Server 6500 fails due to loss of power, network
connection etc., the backup Spectralink IP-DECT Server 6500 will continue to provide service after a
short failover time.
When the master Spectralink IP-DECT Server 6500 returns to operation, it will resume its normal
operation in cooperation with the backup Spectralink IP-DECT Server 6500.
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 Server 6500
If the master Spectralink IP-DECT Server 6500 has been damaged, lost or had its data erased, it will
have to be replaced by the backup Spectralink IP-DECT Server 6500 in order to return the system to
normal operation mode. This is done by promoting the backup Spectralink IP-DECT Server 6500 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 pro-
cedure of setting up a backup Spectralink IP-DECT Server 6500.
Note:
Please be aware that if for some reason a repaired or replaced former master Spec-
tralink IP-DECT Server 6500 is reinstated as master, it should be done very carefully.
First, it must be configured as a backup Spectralink IP-DECT Server 6500 in order to get
the current user data and configuration from the acting master Spectralink IP-DECT
Server 6500 (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 Spectralink IP-DECT Server 6500.
