Appendix A: Cable Requirements
A.1 Ethernet Cable
A CAT 5~7 UTP (unshielded twisted pair) cable is typically used to connect the Ethernet device to the Modem. A: 10/100TX
cable often consists of four pairs of wires, two of which are used for transmission. The connector at the end of the
10/100TX cable is referred to as a RJ-45 connector and it consists of eight pins. The Ethernet standard uses pins 1, 2, 3
and 6 for data transmission purposes. (Table A-1 10/100TX)
B: 1000TX cable often consists of four pairs of wires, all of which are used for transmission. The connector at the end of the
1000TX cable is referred to as a RJ-45 connector and it consists of eight pins. The Ethernet standard uses pins 1, 2, 3, 4, 5
and 6 for data transmission purposes. (Table A-1 1000TX)

Appendix C: Troubleshooting
Diagnosing Giga Media Converter Indicators
The Giga Media Converter can be easily monitored through its comprehensive panel indicators. These indicators assist in
identifying problems the Media Converter may encounter. This section describes common problems you may encounter and
possible solutions:
1. Symptom: POWER indicator does not light up (green) after power on.
Cause: Defective External power supply
Solution:
Chec the power plug by plugging in another that is functioning properly. Chec the power cord with
another device. If these measures fail to resolve the problem, have the unit power supply replaced
by a qualified distributor.
2.
Symptom: Lin indicator does not light up (green) after ma ing a connection.
Cause: Networ interface (ex. a networ adapter card on the attached device), networ cable, or switch port
is defective.
Solution:
 Verify if both of the Media Converter (all devices) and attached device are powered on.
 Be sure the Ethernet cable and fiber optics are plugged into both the switch and corresponding
device.
 Verify that the proper cable type is used and its length does not exceed specified limits.
 Chec the Adapter on the attached device and cable connections for possible defects.
 Replace the defective Adapter or cable if necessary.
 Verify SFP Mode setting is correctly and repower after DIP switch setting

System Diagnostics
Power and Cooling Problems
If the POWER indicator does not turn on when the power cord is plugged in, you may have a problem with the power
outlet, power cord, or internal power supply. However, if the unit power is off after running for a while, chec for loose
power connections, power losses or surges at the power outlet. If you still cannot isolate the problem, then the internal
power supply may be defective. In this case, please contact your local dealer.
Installation
Verify that all system components have been properly installed. If one or more components appear to be
malfunctioning (e.g. the power cord or networ cabling), test them in an alternate environment where you are sure that
all the other components are functioning properly.
Transmission Mode
The default of transmission mode for RJ-45 ports is 10/100/1000 Mbps ETHERNET, for SFP port are
1.25Gbps/2.5Gbps SFP mode. Therefore, if the Lin signal is disrupted (e.g. by unplugging the networ cable and
plugging it bac in again, or by resetting the power), the port will try to re-establish connection with the attached device
via auto-negotiation
Physical Configuration
If problems occur after altering the networ configuration, restore the original connections, and try to trac the problem
down by implementing the new changes, one step at a time. Ensure that cable distances and other physical aspects of
the installation do not exceed recommendations.
System Integrity
As a last resort verify the switch integrity with a power-on reset. Turn the power to the switch off and then on several
times. If the problem still persists and you have completed all the preceding diagnoses, then contact your dealer.
