====== Device administration ======

Tenants can use only the devices assigned to them. The group administrator decides which device is assigned to which tenant. To open a list of all devices (assigned to all tenants), choose //Administration -> Devices// in the main menu.

The group administrator cannot connect a new device to ActiveView. It has to be assigned to one of the tenants by a global ActiveView administrator. Then the group administrator can reassign it to another tenant from the same group.

Every device has the following properties in the administration context:
  * **Serial No** – device serial number.
  * **Type** – device type. The pair //type// – //serial number// is always unique.
  * **Name** – device name in the administration context. This name is separate from the name a tenant’s user can assign to the device (i.e. it doesn’t change when a tenant’s user changes the device name). When the device connects to ActiveView for the first time, it receives a name in the following form: <type>; <serial number>; <date and time>.
  * **Tenant** – the tenant the device is assigned to. The group administrator can assign a device only to a tenant from his/her own group.

===== Removing a device =====

Removing a device doesn’t affect past events or alarms. They are still available unchanged in the alarm browser and in the reports (accessible in the tenant’s context).
