Signal contact
Figure 10: Signal contact: 2-pin terminal block with screw locking
The signal contact is a potential-free relay contact.
The device allows you to perform remote diagnosis via the signal contact. In
the process, the device signals events such as a line interruption. When an
event occurs, the device opens the relay contact and interrupts the closed
circuit. The management setting specifies which events switch a contact.
You can also use the management to switch the signal contact manually and
thus control external devices.

Ethernet ports
You can connect end devices and other segments to the device and media
module ports using twisted pair cables or optical fibers (F/O).
