      7 At work I recently came across a locked down TP-Link managed switch. I could access the password interface using a web browser but the password had already been set and there's no reset button on the device itself.

      9 No matter, a bit of searching and I found how to default these using the console port and a serial cable.

     11 Firstly you're going to want to find your COM address, then connect to it with the following options:
     12 
     13 * Speed: 38400
     14 * Data: 8 bit
     15 * Parity: none
     16 * Stop bits: 1 bit
     17 * Flow control: none
     18 
     19 Power on the switch while connected and hammer your [ENTER] key until you see a `tplink>` prompt. Enter `2` as your option, then `Y` to confirm device reset.

     21 Once the device reboots you should have a defaulted switch where you can now login.
