Setting up redundancy

The nTouch 180 redundancy system allows a standby unit to replace an active unit on the network if it stops functioning.

When the system is used, the configuration settings from the active unit are automatically copied to the standby unit to keep them synchronized. The two units are responsible for a single role. There are two main modes of operation:

If Kiosk users are connected to a project hosted on an nTouch 180 unit when it fails, they will be automatically connected to the project on the backup unit after a short delay.

Notes:

To set up redundancy when using a primary unit and a backup unit

  1. Power up both the nTouch 180 units.
  2. Connect to the web interface on the backup unit.
  3. On the Special screen, under Redundancy, type the IP address of the primary nTouch 180 unit in the Peer Unit Address box.
  4. In the Timeout box, type the number of seconds to wait after the backup unit has lost contact with the primary unit before the backup unit takes control.

    Waiting for a period of time allows the primary unit to start and load the project after a normal power cycle, preventing the backup unit from taking over automatically. It also allows for when communications between the primary and backup unit stop for a few seconds because of a slow network, for example.

  5. Click Set to confirm the action.

    You will be asked to log on.

  6. Specify your username and password. The default username is superuser; it has no password.
  7. Restart the backup nTouch 180 unit.

To set up redundancy when using two units as peers

  1. Power up both the nTouch 180 units.
  2. Connect to the web interface on the first unit.
  3. On the Special screen, under Redundancy, type the IP address of the second nTouch 180 unit in the Peer Unit Address box.
  4. In the Timeout box, type the number of seconds to wait after this unit has lost contact with the other unit before this unit takes control.

    The same value can be specified on both units. This is because if they both start at the same time, they will negotiate to determine which unit will be active and which will operate in standby mode.

  5. Click Set to confirm the action.

    You will be asked to log on.

  6. Specify your username and password. The default username is superuser; it has no password.
  7. Restart the first nTouch 180 unit.
  8. Repeat steps 2-7 for the second nTouch 180 unit.
