    Hi Wani,

    The failure symptom is “OSC SFP” testing failed which the system will simulate the communication package and loop back to confirm.

    And found that the communication package was loss. Found during the automate testing, and the manual checked is confirmed.

    For more details. I have update you in separate mail.. Thanks
