QFX5220-32CD Network LEDs
The high-speed QSFP-DD network ports use a single bi-colored LED to indicate link status, activity on the
link, or a fault condition. The 10-Gbps SFP+ ports have separate bi-colored LEDs; the left LED indicates
link and activity and the right LED indicates fault conditions. See Figure 5 on page 30 .
