Concept
An Unmanaged Switch is not equipped with either configuration function or self-diagnostic
function so that it can be placed only on the edge of the Vnet/IP network.

Figure Vnet/IP network architecture
The edge of the Vnet/IP network is a point to connect Vnet/IP stations and a Vnet/IP network.
When an Unmanaged Switch place on the edge of a network fails, the failed part of the network
can be inferred by using Network Status Display Dialog Box in HIS.
Do not place an Unmanaged Switch on a point other than at an edge of a network because
analysis of network failure cannot be performed.

A local connection or an Edge-point connection is applicable to Unmanaged Switches.
