# System reset

The communication server can be rebooted with a restart or reset to its default values using a first start.

## Restart of the communication server

A restart reboots the entire communication system. The configuration data is preserved.

Note:

- Never disconnect the communication server from the power supply to trigger a restart. This can result in data losses and prevent a restart.
- The restart is triggered immediately. All the active call and data connections are interrupted.

## First start of the communication server

A first start has the effect of resetting the communication server from scratch. The system-specific data such as the system ID, system type, sales channel, licence code, software generation and IP address of the system are preserved.

notes:

- The first start is triggered immediately. All the active call and data connections are interrupted.
- A first start deletes all the configuration data already stored and replaces it with the default values of the sales channel. Therefore, always create a backup before configuration data first start.

## Shutting down the communication server (Mitel 470 only)

Before disconnecting the communication server from the power supply, the Call Manager card (CPU1) and the application card (CPU2-S) must be shut down in a controlled manner. Both cards can be jointly or separately shut down via the control keys close to the display on Mitel 470.

notes:

- Never disconnect the communication server from the power supply before it is completely shut down (CPU1 and CPU2-S). This can result in data losses and prevent a restart.
- The call manager card (CPU1) can only be shut down via the control keys of the Mitel 470 display. The application card (CPU2-S) can also be shut down via WebAdmin.
- The shutdown is immediately triggered. All active call and data connections are interrupted, and all applications closed without warning the user.

## Shutting down and restarting application card (Mitel 470 only)

The operating system of the applications card is shut down regularly and the applications card is deactivated or restarted.

Note:

The shutdown is immediately triggered. All applications are closed without warning the user.
