Description
The Security module (firewall) FN2009-A1 is a firewall router for securely
decoupling the Ethernet network with an external network. The firewall protection
can extend over the operation of individual stations, several stations or entire
network segments. The FN2009-A1 also offers secure access via VPN channels.
The FN2009-A1 splits networks into two areas.
Internal network as protected area
External network as area outside the protected nodes
The FN2009-A1 has two RJ45 interfaces for connecting to the electric Ethernet and
one detector contact. The FN2009-A1 is supplied via the system supply of the
station in which the FN2009-A1 is fitted. If the FN2009-A1 is fitted in a separate
housing, it is supplied from the station located right next to the separate housing.
