How to reset the switch to the default factory settings using PuTTy?
If you use a micro USB cable to reset the switch, please refer to https://www.tp-link.com/support/faq/3146/.
For the switches without the Reset button, you can use the reset command in privileged EXEC mode to restore the system. If you have forgotten the username or password, please use PuTTy to reset it.
