We recently replaced IB switches (both of int-a,b) to newer model, SX6790 36 port IB switch.
After replacing, we noticed that some port LEDs showing abnormal/non-defined behavior;
i.e. Port#8 LED of int-b switch was flashing amber continuously (port#8 was connected to Node8/int-b).
We replaced the IB-cable and then port8 LED became normal(solid green).
Please tell us the meaning of amber LED flashing, it’s possible impact and implication, and fix/workaround.
