LED activity interpretation

System activity and status can be determined through the activity of the LEDs on the switch.
There are three possible LED states: off (no light), a steady light, and a flashing light. Flashing lights
may be slow, fast, or flickering. The LED colors are either green or amber.
Sometimes, the LEDs flash either of the colors during boot, POST, or other diagnostic tests. This is
normal; it does not indicate a problem unless the LEDs do not indicate a healthy state after all boot
processes and diagnostic tests are complete.

Brocade ICX 6650 front panel LEDs

The Brocade ICX 6650 has the following LEDs on the front panel:
•Two Power Supply Unit (PSU) bicolor status LEDs (green and amber) labeled PSU1 and PSU2.
•One DIAG LED bicolor status LED (green and amber).
•Four 1x40 GbE QSFP port status LEDs (blue) which indicate the status of the 40 GbE ports
located on the rear panel.
•Eight 4x10 GbE QSFP-to-SFP breakout port status LEDs (green) which indicate the status of the
4x10 GbE breakout ports located on the rear panel.
•56 10 GbE bicolor status LEDs (green for 10 GbE and amber for 1 GbE) which indicate 1/10
GbE mode of operation.
