ads9-v2ebz - bug on board

Dear support , 

Before starting FA/RMA procedure on ads9-v2ebz.
Can you confirm me that no simple debug can be do on the following issue? Otherwise tell us.

ads9-v2ebz Board behavior description :
At board power up, the five fans start rotating then stop a few seconds later.
We also noticed that a led called "latch" turns red for one second before turning off.
Then this sequence repeats until manual board power off.

(Evaluation board is : "EVAL-ADRV9029")

Thank you and best regards, Thomas
