Problem with Cisco SG300 switch

[aegx00001]

Hi guys,

I have a problem with Cisco SG300-20 switch. After power outage the switch boots in some kind of mode. It requires

MAC address and Serial number to be entered manually for the device. I tried to find information about this mode but without success.

My question is: What is this mode and how to make the switch boot in this mode ?

How can I boot the switch in this mode on purpose if that happens again and I enter the wrong information by accident.

Thanks

Hi Aegx, this is a rare incident where the switch essentially forgets its identity. Although the switch is recoverable, it is recommended to RMA the switch.

If you are certain you have no warranty coverage, all of the information that is asked is on the bottom sticker of the switch. If the sticker is not present you wouldn't be able to make this correct.

In addition, if you make a typographical error, the switch will have adverse failures which are permanent such as the inability to update software.
