Make sure to make a connection to the TX port before make a connection to the
fiber port, a link condition will be sensed on the fiber port whenever the media
converter detects a link condition on the TX port
y
There are two pins on the DIP switch of the 1000Base-T and 1000Base-SX/LX
one-channel media converter:
¾
Toggle up the pin on the left-hand side to let the fiber port auto detect
duplex mode.
¾
Toggle down the pin on the left-hand side to force the fiber port to full duplex

<Note> One of the fiber ports should be forced to full duplex mode and the other fiber
port should be set to auto detect duplex mode when two 1000Base-T and
1000Base-SX/LX one-channel media converters are connected to each other via fiber
port.
