Alarm contact (Relay Contact)
The alarm contact allows the connection of any external alarm system in order to
monitor the operation status. The contact is a 3-ping plug connector at the front of the
switch module. There are both pins, normally open (NO) and normally closed (NC)
available.
The contact is switched in case of a power loss. If the switch is confidured into ring
mode the contact is also switched if the fiber ring is broken in one segment.
Geschaltet wird bei Ausfall der Hauptstromversorgungsspannung. Ist der Switch für
den Ringbetrieb konfiguriert, so wird zusätzlich die Unterbrechung der Glasfaser-
Verbindung signalisiert.
ATTENTION: The maximum power level for this contact is 0.5 A at 60 V DC. It is NOT
allowed to connect devoces with 230 V AC power there.
Transmission Speed
The Twistes Pair ports of the switches are selecting automatically the highest possible
speed by using autonegotiation. The LEDs are indicating the selected mode.
The LEDs are showing the following information.

Twisted Pair Coinnections
The integrated auto-crossing function of all Twisted-Pair ports makes the use of crossed
patch cables unnecessary. The switch automatically detects the pinout of the connected
cable and adapts the port accordingly. For all connections standard 1:1 Twisted Pair
cables can be used.
The Autonegotiation mechanism detects automatically the speed and transmission
mode (full or half duplex) between connected ports. A manual configuration is not
required but possible via the integrated management.
