iKVM not working / Update Timeout

Hello, thank you.

I have a problem with iKVM card in M1000e Chassis, we upgrade driver to version 1.0.1.1, but currently, CMC detects iKVM but it is not working, we had attempt to update the firmware from CMC Webpage and SSH (racadm) with the command "racadm fwupdate -g -u -a [OurServerTFTP] -d ikvm.bin -m kvm.

15 minutes after of update initiate CMC shows this message: iKVM firmware update aborted: Timeout.

RACADM show this information about KVM:

===============================================================================
KVM Information
===============================================================================

KVM Present Avocent iKVM Switch Not Ready

===============================================================================

I think that iKVM has not receive the update request, because CMC error is Timeout.

Please, Do you have any suggest to this problem?

PD:

I read about the problem in forums, but I believe that the solution is change iKVM module.

CMC shows me this values, look that firmware version cannot load.

Thank you very much !!!
