1.4 Unauthorized network access
Connecting devices to a network via Ethernet entails the danger of unauthorized access to
the network.
If possible, deactivate unused communication channels.
Assign passwords such that third-parties cannot access the switch and make unauthorized
changes.
Due to its communication interfaces, the switch should not be used in safety-critical appli-
cations unless additional security appliances are being used.
Please take additional protective measures in accordance with the IT security requirements
and the standards applicable to your application (e.g. virtual networks (VPN) for remote
maintenance access, firewalls, etc.) for protection against unauthorized network access.

“Phoenix Contact”, from all third-party claims made due to improper use.
For the protection of networks for remote maintenance via VPN, Phoenix Contact offers the
mGuard product series security appliances, which you can find described in the latest
Phoenix Contact catalog (phoenixcontact.net/products).
