EXAMPLE DIP SWITCH SETTINGS:
TWISTED-PAIR AUTO-NEGOTIATION:
Set auto-negotiation (DIP switch #1) to select auto-
negotiation: ON=UP
Set twisted-pair full-duplex/half-duplex (DIP switch #2) to
select full-duplex: ON=UP
Set twisted-pair 10BASE-T/100BASE-TX (DIP switch #3) to
select 100BASE-TX: ON=UP
TWISTED-PAIR FULL-DUPLEX 100BASE-TX:
Set auto-negotiation (DIP switch #1) to de-select auto-
negotiation: OFF=DOWN
Set twisted-pair full-duplex/half-duplex (DIP switch #2) to
select full-duplex: ON=UP
Set twisted-pair 10BASE-T/100BASE-TX (DIP switch #3) to
select 100BASE-TX: ON=UP
TWISTED-PAIR 10BASE-T WITH MODE AUTO-NEGOTIATION:
Set auto-negotiation (DIP switch #1) to select auto-
negotiation: ON=UP
Set twisted-pair full-duplex/half-duplex (DIP switch #2) to
select full-duplex: ON=UP
Set twisted-pair 10BASE-T/100BASE-TX (DIP switch #3) to
select 10BASE-T: OFF=DOWN
FIBER FULL-DUPLEX 100BASE-SX:
Set fiber full-duplex/half-duplex (DIP switch #4) to select
full-duplex: ON=UP
FIBER HALF-DUPLEX 100BASE-SX:
Set fiber full-duplex/half-duplex (DIP switch #4) to select
half-duplex: OFF=DOWN
Connecting Fiber Cable to TX/RX Connector
(100BASE-SX)
100BASE-SX AND THE FAST ETHERNET COLLISION DOMAIN
•
Refer to the 512-Bit Rule (page 7) before installing half-duplex
100BASE-SX cable.
•
Using full-duplex fiber cable avoids collision domain
considerations and extends distances up to 2 kilometers
(multimode) or up to 20 kilometers (singlemode).
•
NOTE: A Fast Ethernet collision domain can have ONLY ONE
CLASS I repeater OR TWO CLASS II repeaters.
INSTALLING CABLE
To install 100BASE-SX cable:
1. Locate or build 100BASE-SX cables:
•
100BASE-SX compliant (page 11)
•
with male transmit (TX) and receive (RX) fiber connectors
installed at both cable ends.
2. Connect transmit cable connector at one end of fiber cable to
bridging media converter connector marked with an “outbound”
arrow; connect receive cable connector to bridging media
converter connector marked with an “inbound” arrow.
3. Connect other end of cable installed at transmit (TX) connector of
bridging media converter to receive (RX) connector on network
device; connect other end of cable installed at receive (RX)
connector of bridging media converter to transmit (TX) connector
on network device.
Powering the Bridging Media Converter
To power ON the bridging media converter:
1. Locate power receptacle on back of bridging media converter
2. Connect the bridging media converter power connector end of the
power supply adapter to the power receptacle on the back of the
Transition Network’s bridging media converter.
3. Connect the external power connector end of the power supply
adapter to external AC power.
NOTE: After the power supply adapter is connected to the bridging media
converter and to external power, the green Power LED is illuminated.
