6.5 Interface with a wireless LAN interface

6.5 Interface with a wireless LAN interface
The wireless LAN interface is implemented with a WLAN access point that is connected to
the X1P1 data interface.
To ensure the required accessibility and IT availability of the 7KN Powercenter 3000,
products must be used that have suitable transmission ranges and redundancy measures as
specified by the manufacturer. To achieve this, the antenna equipment has to be mounted
on the outside of the switchboard.

Security aspects of the wireless LAN interface

It is much easier for unauthorized parties to access a wireless LAN than a cabled Ethernet.
For this reason, the wireless LAN is only used for its specific purpose and is administered
restrictively to ensure this.
6.6

Interface with a mobile service interface

Benefits: If a switchboard that works autonomously, i.e. without local network infrastructure,
is to be included for monitoring and diagnostics, IP communication can be implemented by a
secure remote router.
The remote router communicates with the smart switchgear assembly via the public network,
e.g. mobile wireless network, through a tunnel (VPN = virtual private network) with a remote
VPN node. This node can be either a remote router or a SOFTNET Security Client if only
one PC is to have access.
See Overview document: Secure remote access with VPN
