  @barrolete The swich received no ip-adress from a dhcp server anymore. I spent a lot of time to etablish a connectio to the Switch over the Micro-SD Port. No chance. I tested a lot of different combinations (cables, OS-Versions...)

I tried also a RJ45 to USB Adapter cable. No Chance.

 

Why implement TP-Link no Hardware Reset Button to this switch? Was it to expensive?

 

 

1. Have you confirmed that all of your steps were correct in the software we recommend you use for the console access?

2. What did you do or change to the device that caused it to lose all the connections? If you can confirm that there is no change at all to the switch and it lost connection, you can probably consider it a hardware issue.

Do you have VLAN? Can you verify they working properly and the cable's fine?

3. The switch is meant to be mounted to the server rack for professional use. This is the common practice to avoid any reset button on the server-rack-ready products in case someone has physical access to the switch and reset it. Layer 3 switch usually is used as the core switch. They don't offer the reset button. It's not about the cost.

If you are aware of what switch you have, you should not complain about this. If it does not fit your expectations, you may consider models that support a reset button. For example, SG2428, layer 2+.
