How to reset my switch to factory default

[kwchiang]

Hi all! I bought a Summit X460-24 switch from another seller . when I went to the terminal in puTTy and the console screen is blank.  How to reset the switch to factory setting so I can use “admin” to log in console?

When you perform a hard reset (removing the power cable) do you see the boot process on the console?

It is still blank screen console with one blinking cursor..

The serial connection parameter is correct as I used it to connect with different EX switch before.

kwchiang,

First of all, double check the serial connection parameters.

From the doc:

• 9600 baud
• 8 data bits
• 1 stop bit
• no parity
• XON/OFF flow control enabled
• For console port access, you may need to press [Return] several times before the welcome prompt appears.

then from this: https://gtacknowledge.extremenetworks.com/articles/How_To/How-to-default-a-switch-when-the-password-... 

• Power cycle the switch while connected to the console port.
• When prompted, press and hold the spacebar to enter the boot rom
• At the boot rom prompt, type the command config none
• Type the command boot to continue the boot process.
• Once the switch boots up to EXOS, save the config with the command save to overwrite the old config with the new, blank config.
