3650 without password

Markus

Hi,

i have a 3650 with NO password, this means no access to config menu to change password etc.

When i start the switch in ROMMON the flash filesystem is in read-only mode so i can not install copy a new file to the switch

dir-output

xmodem[0]: (read-only)
null[1]: (read-write)
bs[3]: (read-only)
usbflash0[10]: (read-write)
flash[19]: (read-only)
tftp[20]: (read-write)

How can i reset the switch to factory default settings. Holding Mode-Button doesn't work. Copy, Installing, EXEC commands doesn't work without password

When you were in ROMMON did the use the procedure under the heading "Procedure with Password Recovery Enabled" ?  Especially the bit about setting the environment variable "SWITCH_IGNORE_STARTUP_CFG=1" ?

The interesting bit:

1. Power off the switch

2. Power on the switch.  Within 15 seconds, press the Mode button while the System LED is still flashing green.

3. Continue pressing the Mode button until all the system LEDs turn on and remain solid; then release the Mode button.
