C9300 switch reset to factory

[NetAdminMBC]

So, got a brand-spankin' new Catalyst 9300.  Racked it up, connected to console port with PuTTY, booted the switch.  Went through the basic configuration script.  When it was done, I tried to enter enable mode and found I couldn't - evidently, I fat-fingered the password. 

I don't care about the config that's on there now- it's easily re-creatable.  I'd like to erase the startup config and start over, but I can't seem to get there.  Is there a procedure document somewhere that will tell me?  I vaguely remember, with older switches, breaking into the power up routines and erasing the config from flash.  Is that still possible?

I cannot get this method to work at all. No matter how many times or how long I press the mode button after a power cycle, the switch still boots up completely. I was able to put in "system ignore startupconfig switch all" in the regular configuration menu, and rebooted, but it seems that only reset my mgmt IP address and the host name, all the VLANs and it looks like some other configuration I did previous are still there?! I just want to set this thing back to actual factory defaults.

Yes, it works for me.

After following this procedure, I can not get my switch to load the config.  I have 2 switches in a stack and tried the CFG=0 on both but they still boot to the switch> prompt.  Any other suggestions?

Easiest factory reset I've ever done.  I also added the write-erase cmd just for my sanity. Thx!!

To completely wipe the switch, boot as normal and enter factory-reset all from switch> after you confirm twice, it will boot you into rommon and from there you will need to load the OS on there. After that, you can configure the switch as normal.
