Cause and Solution
Cause: Mellanox Onyx (MLNX-OS) software did not
boot properly and only firmware is running.
Solution: Connect to the system via the console port,
and check the software status. You might need to contact
an FAE if the Mellanox Onyx (MLNX-OS) software did
not load properly.
Cause:
• Critical system fault (CPU error, bad firmware)
• Over temperature
Solution:
• Check environmental conditions (room temperature)
Cause: Possible fan issue
Solution:
• Check that the fan is fully inserted and nothing
blocks the airflow
• Replace the fan FRU if needed (possible in SN2700,
SN2740 and SN2410 only)
Cause: Possible PSU issue
Solution:
• Check/replace the power cable
• Replace the PSU if needed (possible in SN2700,
SN2740 and SN2410 only)
