This chapter contains information to help you solve issues. If the GST-70x is not functioning properly, make sure the
GST-70x was set up according to instructions in this manual.
The Power LED is not lit
Solution:
Check the power cable connection between power adapter and GST-70X.
Why I connect GST-70x to device with 1000Base-LX/SX interface and the 1000Base-LX/SX fiber con-
nection fail?
Solution:
1.
Please check the fiber connection between two devices is correct.
2.
Please check the 1000Base-LX / SX interface from both devices run at force full duplex mode.
3.
Check and if the 1000Base-LX/SX interface of other device run at Auto-negotiation mode only,
please enable the Auto negotiation bypass function of GST-70x for successful fiber connection.
1000Base-T port link LED is lit, but the traffic is irregular
Solution:
1.
Check that the attached device is not set to dedicate full duplex. Some devices use a physical or software switch
to change duplex modes. Auto-negotiation may not recognize this type of full-duplex setting.
2.
Check and assure the TP ports from both GST-70x and attached device run at Auto-negotiation mode.
Why I change the GST-70x DIP switch setting and seems the function without any different?
Solution:
Please power off and power on the GST-70x to take effect.
