Hello All,
We are unable to reset our switch to the factory settings. Its a new switch out off the box that we configured (attempted to configure) and hosed it up. The factory default password isn't working user ID cisco and PW using the system SN. We tried removing the power, holding the mode button and restoring power with no luck. It does boot to the "switch:" prompt but nothing after this point. Could you please advise how we can resolve this issue?
Thanks,
Patric

Hello @New2Cisco
You sure you follow this ?
Power cycle the switch. Immediatly press and hold the Mode button. Hold the button till the Status LED will go amber. Then on the console you should be in Boot Loader...
In that forum, Mode button does not function like this, so try also:
1.Reboot your C9300
2.Do not touch that Mode button now
3.Pay close attention to the console during boot. When the line "Last reset cause: SoftwareReload" appears, press the Mode button 3 times.

you ave the Rommon prompt switch:
Add the following variables to ignore the startup configuration :
switch: SWITCH_IGNORE_STARTUP_CFG=1
Boot the switch.
switch: boot
Once the switch has booted, copy the saved config back into the run config :
Switch# copy start runn
Next set your password. Remove the variables we set in Boot loader :
switch# no system ignore startupconfig switch all
Save your new configuration:
switch# copy runn start

Hello thanks for the reply. Yes the steps I performed. Removed power from the switch, press and hold the mode button and re-apply power. The switch boots but after a minute the green light flashes. It never turns amber.
As for the second option I did attempt that as well but I believe I missed the mark. Again I will try your suggestion again and update you.
I will try again in the morning. Thanks again for the reply.

That's not going to work.
Please read & understand the response from M02@rt37.

Hello Leo, I am attempting to follow as suggested. "Pay close attention to the console during boot. When the line "Last reset cause: SoftwareReload" appears, press the Mode button 3 times."
When doing so I get the following as shown in the attachment.

Hi MO2@rt37,
I have a similar issue and follow your instructions.
but switch is not accepting the no system ignore startupconfig switch all command.
Now my switch does not load the startup config.
Any ideas on how to resolve this?
Best Regards

If the switch has boot into IOS-XE, post the complete output to the command "sh romvar".
If the switch is in ROMMON, post the complete output to the command "set".
