100BaseFX Ethernet Port Connection
The concept behind the SC/ST port and cable is quite straightforward.
Suppose you are connecting devices I and II; contrary to electrical
signals, optical signals do not require a circuit in order to transmit data.
Consequently, one of the optical lines is used to transmit data from
device I to device II, and the other optical line is used transmit data from
device II to device I, for full-duplex transmission.
Remember to connect the
Tx (transmit)
port of device I to the
Rx
(receive)
port of device II, and the
Rx (receive)
port of device I to the
Tx (transmit)
port of device II.

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 Ethernet Switch power
needs.
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.
