| This page tries to summarize the different physical ways that network devices are internally organized, and how this is mapped into NAV's data model. If you disover factual errors in the device descriptions used here, please don't hesitate to fix them (Disclaimer: I am not a network engineer!) :) | This page tries to summarize the different physical ways that network devices are internally organized, and how this is mapped into NAV's data model.

| + | * A //module// is a device that is somehow related to a netbox. A module is either a physical expansion card or some kind of other IP-less device managed by the Netbox device, such as in the case of stacked switches. | ||

| Different vendors use different terminology to describe their own implementations of these concepts. We will use our own terminology here, but attempt to translate into the names used by the vendors best known to us. | Different vendors use different terminology to describe their own implementations of these concepts.
