Corrective Measures
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
This state can indicate a number of problems:
•
One of the FRUs is not functioning properly (fan or PSU)
•
Critical system fault (CPU error, bad firmware)
•
Over Temperature
To overcome it:
•
Check FRUs. For example, make sure that nothing is
blocking the FAN FRU.
•
Check Environmental conditions (room temperature)
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.
This state is indicative of a problem with the PSU.
•
Check/replace the power cable.
•
Replace the PSU if needed.
Make sure that there is an SM running in the fabric.
