Swapping out an A.I.M. server
Once ALIF devices have been congured to run with an A.I.M. server, their default IP
addresses are automatically changed as part of the installation process. In this state the
ALIF devices become undetectable to any new A.I.M. server that does not have access to
the database of devices. Therefore, if an existing A.I.M. server needs to be replaced within
an installation, follow one of the basic procedures given here to smooth the transition.
The correct procedure to use depends on whether you are using a solo A.I.M. server
(rmware versions below 3.0 can only be used as solo servers) or a pair of A.I.M. servers
in a primary/backup redundancy arrangement:
For solo A.I.M. servers (and those with rmware below v3.0)
1 Before connecting the new A.I.M. server to the main network, connect the new A.I.M.
server to a network switch that is isolated from the main network.
2 Use a computer connected to the same switch to login to the new A.I.M. server
management suite.
3 Ensure that the new A.I.M. server is running the same rmware version as the one
being replaced (upgrade if necessary). The rmware version is shown in the top right
hand corner of every page of the management suite (just below the Adder logo).
4 Set the IP address of the new A.I.M. server to match that of the original unit.
5 Restore a backup le of the original A.I.M. server database to the new device.
6 Remove the original A.I.M. server from the network. Connect the new A.I.M. server in
its place and power up.
The replacement unit should now work directly with the installed ALIF units.
For dual A.I.M. installations using redundancy
The correct procedure depends on which A.I.M. server has failed:
Primary server failure
1 Promote the backup server to be the primary server.
2 Replace the faulty primary A.I.M. server with a replacement unit.
If the replacement A.I.M. server has a rmware version below 3.0 then contact it on
the 169.254.1.3 address and upgrade to 3.0. After the upgrade, reboot the unit.
3 The replacement server should begin communicating with primary server and
download the database so that it can operate as the backup server.
Backup server failure
1 Replace the failed backup server with a new unit that has rmware version 3.0 or
greater and has its default factory settings in place.
2 The replacement server should begin communicating with primary server and
download the database so that it can operate as the backup server.
Starting from scratch
If none of the above procedures are used, then the following will be necessary. This will
require a certain amount of effort because each ALIF unit must be visited and reset, plus
the A.I.M. database will need to be fully recongured.
1 Place a new A.I.M. server into the network and then perform a factory reset on every
ALIF device. This will force the ALIF units back to their default states whereupon they
will announce themselves to the new A.I.M. server.
2 Use a computer connected to the same network to login to the new A.I.M. server
management suite and begin to recreate the database of devices and users.
