3.8 SCALANCE X101-1AUI Button
Signaling Contact
The signaling contact is connected to a 2-pin plug-in terminal block. The signaling contact
(optical relay contact) is a floating switch with which error/fault states are signaled by contact
separation.

contact
The following errors/faults can be signaled by the signaling contact:
• The failure of the link on the monitored TP port (P1).
• The failure of one of the two redundant power supply units.
Connecting or disconnecting a communication node on the unmonitored port (P2) does not
cause an error message.
The signaling contact remains activated until the error/fault is eliminated or until the current
status is applied as new desired status by the button.
When turning off the device, the signaling contact is always activated (open).

What is the function of the button?
Using the button, you can display and modify the set fault mask.
After continuously pressing the button, the currently valid fault mask is displayed for
approximately 3 seconds. The LED of the monitored port flashes at a frequency of 5 Hz.
Keep the button pressed to modify the fault mask. After another 3 seconds, the current link
status of port P1 and the indicator of the power supply LEDs are displayed at a flashing
frequency of 2.5 Hz. Keep the button pressed. After another 3 seconds, this status is applied
as new fault mask and saved. The now monitored port is indicated by the permanently lit P1-
LED until the button is released. As long as the LED is still flashing, the saving can be
canceled by releasing the button.
