## Restart of peripheral boards

### Manual restart

In case of a faulty behavior of a peripheral board, it is possible via a BMS connection to initiate a restart not only on system level but also on individual board level.

1. Connect BMS to the system.
2. Select ’Boards’ in the tree view to open the context menu
3. Click on “Hardware details”
4. Mark the desired board position and click on the ’Restart’ button to restart the board.

- Boards which are currently being used for the connection between BMS and the system connection are marked with “used” on the right side. These boards can not be restarted. The CPU board as such cannot be restarted, the normal system restart function has to be used instead.

### Automatic restart

#### Restart based on warning 10H

As soon as a fatal error condition is detected by a peripheral board, it automatically performs a watchdog restart. A watchdog restart causes a system restart in all ASB 150 02 exchanges with a central software older than Release12.

In systems with central software of Release 12 or higher, it depends on the programming of the command Enable Extended Supervision (see below) whether only an individual board restart will be performed or a complete system restart. The entry in the warning log (10H) is the same as in the prior releases.

1. Connect the BMS to the system
2. Select ’Maintenance’ in the tree view, to open the context menu
3. Click on “Ext. Supervision”
4. Enable or disable the value Ext. Supervision

   Enabled (default) |  | The peripheral board will be restarted automatically. All boards will be supervised every minute to verify if they are still alive. |
   Disabled |  | The whole system will be restarted automatically. Every minute only a single board will be supervised to verify if it is still alive. |

An automatic restart is not performed on following board types:

- BTU-A (A2)
- BTU-E
- BTU-C
- AUX-_
- VMU-D

#### Restart based on warning 97H

The central software of ASB 150 02 maintains a mechanism, where each peripheral interface board is supervised on a periodic basis. Every minute, a single interface board is polled to verify if it is still alive. If the board does not answer in time, a series of additional poll attempts will be initiated. If all supervision attempts fail, a warning 97H, “Card Supervision Failure”, is generated. This warning code is classified as STOP by default. Therefore, a restart of the whole exchange will be initiated in order to resolve the error condition on the peripheral interface board.

For ASB 150 02 systems with a central software of Release 12 or higher, it depends on the programming of the command Enable Extended Supervision (see chapter Restart based on warning 10H) whether only the single peripheral board will be restarted automatically on a Card Supervision Failure or the whole system.

In case of an automatic sequence for the faulty peripheral interface board, the warning code 10H is generated. As a result, a supervision failure of a hardware component will result in 2 entries in the warning log, one indicating the supervision problem and one the resolution, because of the automatic restart sequence for the peripheral interface board.
