Net Unit

The Net Unit implements the connection of the units to the networks of the SE server and to private customer networks. The Net Unit can be designed with redundancy in the interest of protection against failure.

The Net Unit contains the following components:

• Switches
  A redundant Net Unit has redundant switches (by default in the case of SE /390).

• HNC in SE /390
  The HNC connects the Server Unit /390 with the LAN. Up to four HNCs are possible.
