LED information, huawei compatible SFP transceiver, notice

 

Take the HUAWEI compatible SFP transceiver for an example. When we insert the SFP transceiver into the target device; and the LED turns green that means there is a link between the SFP transceiver and the target device.

 

If the LED turns off, the target device may not be turned on. The problems may arise in the cable and adapter. In this case, we should refer to the device guide to solve it. Sometime, we may find the LED turns amber; at the same time, the STP discovers the network topology and searches for loops. This process takes about 30 seconds, and then the LED will turn green.

 

In some cases, we can reconfigure and reboot the target device if necessary.
