About Speed LEDs

Each port has one link LED on the left and one speed LED on the right.
The speed LED displays the speed of the port interface:
•
•
The speed LED also displays if the beacon mode is enabled or disabled:

Bit Error Thresholds

The bit error rate threshold is used by the switch to detect an increased error rate before performance
degradation seriously affects traffic.
The bit errors can occur for the following reasons:
