Troubleshooting
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 "EEE conforming to IEEE802.3az (LPI)" function at target port.

Are the communication speed and mode settings correct?

If the communication mode signal cannot be properly obtained, the Ethernet Switch
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 Ethernet Switch is connected excessively

high?
Try separating this Ethernet Switch from the network.
Are the port LEDs lit up orange?

If the port LEDs are lit up orange, the ports will be blocked via the loop detection
and blocking functions. After the port controlled loop connections are resolved,
release the port blocking from the settings screen as to whether the standby time
will be longer than the recovery time until the auto-recovery of the loop detection
and blocking.
Stacking Failure

Is the stacking function enabled?

Is the 40G direct attached cable connected to stacking port (port 29 or 30) 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?
