Local fail-over to secondary master initiation

The fail-over operation should be initiated when it is determined that the primary
master module is in a hard fault condition.
1. From the secondary master touch screen, select Menu.
2. Select Maintenance. The Secondary Master Maintenance screen will appear.
3. Select Fail-Over to Secondary Master.
The library will transfer control of the cartridge elevator to itself, power down
the primary master, then reboot.

Remote fail-over to secondary master initiation

Toconfigure the secondary master for remote fail-over, complete the following
procedure:
1. If the library is connected to a network, use a Webbrowser to connect to the
library’s fail-over URL, which uses the same IP address of the library’s Web
TLC, but uses port 8008. For example, if the WebTLC address is 10.1.15.77, the
fail-over URL will be http://10.1.15.77:8008.
2. Log in.
3. Select Fail-over to Standby Module.
4. Confirm that you want to fail-over to the standby module.
The secondary master will transfer control of the cartridge elevator to itself,
power down the primary master, and then reboot.
Restoring normal operation
After the failed module is replaced, a procedure similar to the one described in the
previous section can be invoked to restore the original operation. In order for the
restore operation to take effect, the future master module must be connected as the
inactive primary master.

Local fail-over to primary master

Toconfigure the primary master for local fail-over, complete the following
procedure:
1. From the secondary master touch screen, select Menu.
2. Select Maintenance.
3. Select Fail-over to Primary Master.
The secondary master will transfer control of the cartridge elevator back to the
primary master and then reboot.
