The QSFP-DD port status tri-colored (RGB) LEDs are located to the right of each port, as shown in . The LEDs indicate a link to the port, the rate that is configured for the port, and active traffic on the port. The LEDs can also indicate fault conditions.
The meaning of the colors and states for the QSFP-DD port LEDs are described in QSFP-DD Port Status LEDs.
