DIP Switches
All DIP switches are off by default.
DIP
Switch 1
The Ethernet link is auto-negotiating when the switch is off.
Turn it on to force the Ethernet link to be up at only 100Mbps
in full duplex mode.
DIP
Switch 2
The fiber link operates in full-duplex mode when the switch is
off. Turn it on to have the fiber link operate in half-duplex
mode.
DIP
Switch 3
Turn this switch on to enable Link Loss Forwarding. A
message is sent to the Ethernet port if the fiber link goes
down (thus forcing the Ethernet link down) and vice-versa.
DIP
Switch 4
When this switch is off, the Ethernet port uses a store-and-
forward switching scheme, in which incoming data frames are
first stored in buffer memory and checked for errors before
being forwarded. Turn this switch on to have the Ethernet port
operate in pure converter mode in which the port forwards the
received data frame immediately after being received (without
error checking).
Do not turn a DIP switch on or off when a port is transmitting
or receiving data as it may cause data error or loss.
Fiber Transceiver
The MC100FX-SC2 comes with a built-in multimode fiber transceiver
with SC connector that can be used for connections of up to 2km.
The MC100FX-SC30 comes with a built-in single mode fiber
transceiver with SC connector that can be used for connections of up to
30km.
SFP transceiver modules are dust sensitive. Avoid getting dust and other
contaminants into them.
SFP transceivers are equipped with a Class 1 laser, which emits
invisible radiation. To avoid possible eye injury, do not look into an
operating fiber-optic module’s connectors. Laser radiation is also
present when the media converter is turned on.
