Catalyst 9300 console port not recognized (USB-UART or USB-RJ45)

[ARCenBois]

Hello there,
My company gave me a switch catalyst 9300 24P, as it is not new I want to return it to its default settings. I tried to connect using the front console port but my computer does not recognize it as a cisco device (but the cable connection is detected by the device manager). Same thing for the serial console port in the back. There is no way I can get a console for the switch using the ports and I do not have any IP to try to ssh to. I tried to use physical buttons methods when powering on without success for now.

edit : already tried multiple pc/cables, working on another switch but not this one

Does anyone have an idea of how I can recover the switch from this ?
Thank you in advance.

Hello @ARCenBois ,

for this kind of situations, you need to access the switch using the console port. Try a different console cable and/or a different PC.

Once you have access to the console of the switch, use the steps described here: https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst9300/software/release/16-6/configuration_guide/sys_mgmt/b_166_sys_mgmt_9300_cg/b_166_sys_mgmt_9300_cg_chapter_01100.html#task_nzq_q4z_n1b

Hope this helps.

Hello, I tried with 3 different laptops (win10 and win11) and same number of cables.
I finally find a way to access it via ssh (provisioning it with the cdnac) but I still cannot access it via console port.
It may be linked to the pc drivers...
Thanks for the help, still not resolved

Use a different PC.

Ok problem solved, the catalyst was more recent than my pc, so I had to set new drivers https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers
