Troubleshooting
If you find any problem, please take the following steps to check.
LED
* The POWER LED is not lit.
-
Is the power plug connected?
Check that the power plug is firmly connected, so the connection is not loose at
the power port.
-
Is this Switching Hub used in a place where operating temperature is between 0
and 40 degrees C?
Use the Switching Hub within the range of operating temperature.
* The SD CARD LED is not lit.
-
Is the SD card installed?
Check that the SD card is firmly inserted.
Communication Failure
* Is the UTP/fiber cable connected to the correct port?
* Are the SFP modules complied with the same standard each other?
* Is the fiber cable correct the fiber mode (single or multi)?
* Attempt to disable “Power Saving” function at target port.
* Are the communication speed and mode settings correct?
If the communication mode signal cannot be properly obtained, the Switching Hub
operates in half-duplex mode. Check the auto negotiation setting again.
Do not fix the speed/duplex mode of the connected terminal to full-duplex mode.
* Is the usage rate of the network to which this Switching Hub is connected excessively
high?
Try separating this Switching Hub from the network.
Stacking Failure
* Is the stacking function enabled?
* Is the SFP+ direct attached cable connected to stacking port (port 27 or 28) correctly?
* Is the STACK ID LED displayed the correct ID?
* Are all of the firmware versions for the devices that are connected to the stacks
identical?
