Device types are instantiated as devices installed within sites and/or equipment racks. For example, you might define a device type to represent a Juniper EX4300-48T network switch with 48 Ethernet interfaces. You can then create multiple _instances_ of this type named "switch1," "switch2," and so on. Each device will automatically inherit the components (such as interfaces) of its device type at the time of creation. However, changes made to a device type will **not** apply to instances of that device type retroactively.

- This parent/child relationship is **not** suitable for modeling chassis-based devices, wherein child members share a common control plane. Instead, line cards and similarly non-autonomous hardware should be modeled as inventory items within a device, with any associated interfaces or other components assigned directly to the device.

A device type may optionally specify an airflow direction, such as front-to-rear, rear-to-front, or passive. Airflow direction may also be set separately per device. If it is not defined for a device at the time of its creation, it will inherit the airflow setting of its device type.
