Cisco 9500-24Y4C Version Upgrade Issues

[left-zuo]

I upgraded my cisco c9500-24y4c from 17.09 to 17.12.03 today, but my 100G bidi module is not recognized anymore!

what is the reason for this?

Autonegotiation is not supported on HundredGigabitEthernet1/0/49 to HundredGigabitEthernet1/0/52 uplink ports of the C9500-48Y4C models, and HundredGigabitEthernet1/0/25 to HundredGigabitEthernet1/0/28 uplink ports of the C9500-24Y4C models. Disable autonegotiation on the peer device if you are using QSFP-H40G-CUxx and QSFP-H40G-ACUxx cables.

But I am interconnecting two ports on a cisco device and the ports also force 100G

Console into the switch and reboot. 

Post the entire boot-up process.

I don't think this is the way to go as I have rebooted the switch after upgrading the firmware version

Is the BiDi Cisco-branded?
