INSTALLATION
Set Switches
NOTE: Switch labels are located AT TOP of E-R-TX-FX-01 media converter.
Use small flatblade screwdriver or
similar device to set recessed
switches according to site
installation.
•
Set EACH MDI/MDI-X
switch to MDI for cable
connection between
switch and media
converter OR to MDI-X
for cable connection
between media converter and terminal,
transceiver or network interface card (NIC).
•
Referring to drawing, set four-position
switch according to network
configuration.
NOTE: If connecting two (2) media converters in series, set the PST (#4)
switch on one media converter to the UP position AND set the PST (#4)
switch on the other media converter to the DOWN position.
Install Cable
COPPER
NOTE: KEEP TWISTED PAIR RUNS AS SHORT AS POSSIBLE.
•
Locate or build 802.3 compliant cables with straight through
configuration and male RJ-45 plug connectors.
•
Connect male RJ-45 plug connector at one end of cable to media
converter RJ-45 jack connector.
•
Connect male RJ-45 plug connector at other end of cable to DTE
terminal RJ-45 jack connector (with MDI switch set to MDI-X) or to
switch RJ-45 jack connector (with MDI switch set to MDI).
FIBER
•
Locate or build 802.3 compliant fiber cable with male two-stranded TX
to RX connectors appropriate to the media converter installed at both
ends.
•
Connect male TX and RX cable connectors at one end of cable to TX
and RX female connectors, respectively, on media converter.
•
Connect male TX and RX cable connectors at other end of cable to RX
and TX connectors of 802.3 compliant fiber device.
Connect to Power
•
Install Power Adapter cord at back of media converter.
•
Connect Power Adapter 3-prong plug to AC power.
•
Verify that media converter is powered by observing illuminated LED(s).
The two active pairs in a 100BASE-TX
network are pins 1 & 2 and pins 3 & 6. Use
only dedicated wire pairs (such as
blue/white & white/blue, orange/white &
white/orange) for the active pins.
