3850 after upgrade cycling through wired charaters and messages

Hi guys,

I tried to upgrade a 3850 switch from the 3.2.3 to 16.9.4 in the install mode. After the upgrade, the switch does not come up. It is cycling through these messages constantly...

I have tried with reboot. I have tried with pressing mode button while plugging in the power and continue to hold. These message just kept on repeating. I never get the "switch:" prompt. Any idea why? Thanks!

In ROMMON, what happens if you enter the command "boot flash:packages.conf"?

Console into the switch and reboot.
Post the entire bootup process.

Re: 3850 after upgrade cycling through wired charaters and messages

Have you tried holding the "Mode" button for 10secs? If yes & no use, then advise to raise a TAC case as this seems to be a bug or any hw failure.


With best regards...

Sorry for the late response... The email notification for your response was blocked by our email spam filter... I will receive the switches in the new year and try it myself. The switches were at a remote office. As per my onsite personnel, he did press it for more than 30 seconds. I will report back. Thank you.
