INSTALLATION
NOTE: Ensure that two (2) recessed switches located at side of media converter
are set to the UP position. (Use small flatblade screwdriver or similar device to
set switch position, if necessary.)
Install Cable
COPPER
NOTE:
Shielded cables required on DB-9 for EMC compliance.
•
Locate or build TIA/EIA-574 compliant cables with male DB-9
connectors and with straight-through cable configuration for connection
to DTE and/or with null-modem cable configuration for connection to
DCE. (See below.)
•
Connect male DB-9 connector at one end of cable to media converter
female DB-9 connector.
•
Connect male DB-9 connector at other end of cable to DTE female DB-9
connector (using straight-through cable configuration) or to DCE female
DB-9 connector ( using null-modem cable configuration).
FIBER
•
Connect male TX and RX cable connectors at one end of cable to TX
and RX female connectors, respectively, on media converter.
Connect to Power
•
Install power adapter cord at back of media converter.
•
Connect power adapter plug to AC power.
•
Verify that media converter is powered by observing illuminated
LED(s).
