Troubleshooting
If you find any problems of the product (or device) you purchased, please
check the following steps.
◆ LED
○
If the POWER LED does not light up:
●
Is the power-cord unplugged?
Please check if your device is securely connected.
●
Is the device used in the environment where the operating-
temperature is from 0 to 50
℃
? Please use the device within the range
of the temperature above.
○
If the port LED does not light up with the status mode:
●
Are cables securely connected to the corresponding port?
●
Are appropriate cables used?
●
Is the equipment connected to a corresponding port 10BASE-T,
100BASE-TX or 1000BASE-T?
●
A failure may occur because of an auto-negotiation.
●
Do you choose the LED display mode of a correct port with the
LED display switching button?
○
If the port LED (right-side) lights up with an orange color:
●
A loop occurs. Deactivating the loop turns off the orange-colored
light.
○
LOOP HISTORY (a loop history mode): If the LED flashes with a green
color.
●
This indicates the port, which is found during the loop or after
resolving the loop.
