INSTALLATION -- Continued
Set 3-Position Hardware/Software Mode Jumper
NOTE: Jumper is located inside the Media Converter on the circuit board.
CAUTION: Ensure that the external power source is powered off and that
the Media Converter is disconnected from the power source. Also, wear a
grounding device and observe electrostatic discharge precautions.
1.
Ensure that the power supply is off.
2.
Disconnect the external power source from the Media Converter.
3.
Remove and retain the four (4) screws that secure the cover to the Media
Converter.
4.
Carefully remove the cover from the Media Converter.
5.
Use small needle-nosed pliers or similar device to set jumper. Refer to
drawing for jumper positions.
6.
Carefully replace the cover to the Media Converter.
7.
Replace the four (4) screws to secure the cover.
8.
Reconnect the external power source and turn the power supply on.
HARDWARE
Converter mode is determined by switch
settings.
SOFTWARE
Converter mode is determined by most-
recently-saved on-board microprocessor settings.
Set MDI/MDI-X Switch (Hardware Mode Only)
NOTE: The MDI/MDI-X switch, located on the side of the Media Converter,
allows the network administrator to use straight-through cable in installations
where crossover-configuration cable is required.
Use small flatblade screwdriver or similar device to set recessed switches.
Refer to drawing for switch settings.
Set 8-Position Switch
NOTE: The eight-position switch, located on the side of the Media Converter,
allows the network administrator to configure the media converter for
network conditions.
Use small flatblade screwdriver or similar device to set recessed switches for
site installation. Refer to drawings on page 5 for eight-position switch
settings.
•
Verify local fiber connection by starting a remote fiber loopback
(setting the loopback switch on the remote media converter to fiber,
if in hardware mode, or entering the remote fiber loopback
command, if in software mode) and then using a Bit Error test unit to
run a Bit Error test.
•
Verify remote copper connection by starting a remote copper
loopback (setting the loopback switch on the remote media
converter to copper, if in hardware mode, or entering the remote
copper loopback command, if in software mode) and then using a
Bit Error test unit to run a Bit Error test.

CABLE SPECIFICATIONS
Twisted-Pair Copper Cable
Twisted-pair connection requires two active pairs. The two active pairs in a T1/E1
network are pins 1 & 2 and pins 4 & 5. Use only dedicated wire pairs (such as
blue/white & white/blue, orange/white & white/orange) for the active pins.
Category 3 or better twisted-pair copper wire is required. Either shielded twisted-pair
(STP) or unshielded twisted-pair (UTP) can be used.
