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 7750 front panel LEDs
The Brocade ICX 7750-26Q 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).
• One MS LED bicolor status LED (green and amber).
• One HA LED bicolor status LED (green and amber).
• One RDNT LED bicolor status LED (green and amber).
• Four bicolor status LEDs (green and amber) for each of the 26 QSFP+ ports that indicate the
status of the ports in 40 GbE mode and 4x10 GbE breakout mode.
