ATTENTION
This product is intended to be mounted to a
well-grounded mounting surface such as a metal

Wiring the Alarm Contact
The Alarm Contact is made up of the two middle contacts of the
terminal block on the Media Converter’s top panel. Refer to the next
section for detailed instructions on how to connect the wires to the
terminal block connector, and how to attach the terminal block
connector to the terminal block receptor.
In this section, we explain the meaning of the two contacts used to
connect the Alarm Contact.

FAULT
: The two middle contacts of the
6-contact terminal block connector are
used to detect both power faults and port
faults. The two wires attached to the Fault
contacts form an open circuit when:
1.
The Media Converter 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.
Wiring the Redundant Power Inputs
The outer 2 contacts on left and right side of the 6-contact terminal
block connector are used for the Media Converter’s two DC inputs.
Top and front views of one of the terminal block connectors are shown
