ATTENTION
This is a Class 1 Laser/LED product. To avoid causing serious
damage to your eyes, do not stare directly into the laser beam.
Redundant Power Inputs
Both power inputs can be connected simultaneously to live DC power
sources. If one power source fails, the other live source acts as a backup,
and automatically supplies all of the switch´s power needs.
Alarm Contact
The Ethernet switch has one Alarm Contact located on the top panel.
For detailed instructions on how to connect the Alarm Contact power
wires to the two middle contacts of the 6-contact terminal block
connector, see the Wiring the Alarm Contact section on page 7. A
typical scenario would be to connect the Fault circuit to a warning light
located in the control room. The light can be set up to switch on when a
fault is detected.
The Alarm Contact has two terminals that form a Fault circuit for
connecting to an alarm system. The two wires attached to the Fault
contacts form an open circuit when (1) the switch has lost power from
one of the DC power inputs, or (2) one of the ports, for which the
corresponding PORT ALARM DIP switch is set to ON, is not properly
connected.
If neither of these two conditions occurs, the Fault circuit will be closed.
DIP Switch Settings
The default setting for each DIP switch is OFF.
The following table explains the effect of setting
the DIP switches to the ON positions.
