QUICK USER GUIDE
Unidirectional network devices are typically used to provide
information security or protection of critical digital systems,
such as industrial control systems or production networks
from cyber-attacks.
Our TAPs work like a diode and, for security reasons, do not
allow access to the network via the monitoring ports.
By adding this further security layer, it is thus not possible to
compromise the network connection and the productive net-
work.
2. Data Diode Function
Data diodes guarantee unidirectional communication and ensure that data traffic can only flow in one direc-
tion.
3. PoE - Power over Ethernet Functions
The TAP supports both passive PoE and active PoE for passing through the power
supply to a PoE-capable device:
• PoE/PoE+ pass-through according to IEEE802.af - the maximum power con-
sumption that an end device can draw via the TAP is 12.95W
• Power supply of the TAP via PoE according to IEEE802.af (active/passive)
To connect the TAP to a PoE port according to IEEE802.af, please follow the installation steps below:
First connect the TAP to the PSE (Power Sourcing Equipment) device and make sure that the PoE+ LED lights up.
As soon as this lights up, the PSE and the TAP have negotiated the power supply and you can now connect
your PoE end device to the TAP.
This sequence must be followed so that the TAP can properly establish power supply via a PSE device per
IEEE802.af.
All other power supply inputs on the TAP can still be used; the PoE power supply increases the redundancy
in this case.
