Each QSFP-DD/OSFP module can be used as two 4X ports or four 2X ports, and certain modules can
be split to eight 1X ports as well. Each QSFP-DD/OSFP module has one dedicated bi-color LED. In
order to provide link information for more than one port by using one LED, LED splitting control
button is available. You may use the lane select button to select between 8 indication states. By
pressing the button, the next indication state will be selected in a cyclic manner. The current state
can be identified by the LED splitting state indication LEDs. The states and their indications are
