Corrective Measures

LEDs

System Status LED is 
blinking for more than 5 
minutes

This state means that the MLNX-OS software did not 
boot properly and only firmware is running.
To overcome it, connect to the system via the console 
port, and check the software status. You might need to 
contact an FAE if the MLNX-OS software did not load 
properly

System Status LED is red

This state can indicate a number of problems:
• Critical system fault (CPU error, bad firmware)
• Over Temperature
To overcome it:
• Check Environmental conditions (room tempera-

ture)

Fan Status LED is red

This state is indicative of a problem with the FAN.
• Check that the FAN is fully inserted and nothing 

blocks the airflow.

• Replace the FAN FRU if needed.

PSU Status LED is red

This state is indicative of a problem with the PSU.
• Check/replace the power cable. 
• Replace the PSU if needed.
