System parameters reset to zero SG350-28MP

[GBInformatics]

Hello,

I had lost access to the SG350-28MP switch management WEB interface.
I reset the switch by pressing the reset button for 20 seconds, once released a lot of LEDs lit up.

The system LED has been flashing green rapidly for about 1 hour. Then from time to time for a couple of minutes, it turns a steady green. I have access to the WEB interface. RJ45 port 1 is lit green. Then after two minutes, it goes back to flashing green as if it's going round in a loop.

Should I try to reset it again?

On this case I dont see  much option. Try to reset It until it stabilize and make a software upgrade.

I need to take a USB key with the .bin file from the cisco site and put it in the USB port of the Cisco switch?

[Flavio Miranda]

Dont believe you can do It using USB.

Take a look on this vídeo.

You can do from the web interface. In case you can access It.

[GBInformatics]

In short, there's a good chance that it's defective ?...

[Flavio Miranda]

Unfortunatelly, yes.

[GBInformatics]

I'm disgusted, I don't understand what happened to make this happen.

Should I try to install the firmware via the console cable?

[Flavio Miranda]

You need to have network connectivity anyway. You can not transfer the firmware using the console cable.

Can´t you return this device?

[GBInformatics]

I do have a network connection. I can display the WEB management interface during two minutes.

I bought the product from my employer. I'm not sure about yesterday. Except that all my savings have gone to dust for the moment.

[Flavio Miranda]

If you have network connection than follow the video and try to upgrade it. You can use console cable to run the commands.

I believe 2 minutes is enought for you to transfer the file.

[GBInformatics]

I'm a bit confused by the situation. And very worried.

I log on to the interface and then to the cisco account. Then I go to ‘system’ or something like that to put the .bin file downloaded from ‘https://www.cisco.com/c/en/us/support/switches/350-series-managed-switches/series.html#~tab-downloads’ and called ‘image_tesla_hybrid_2.5.9.54_release_cisco_signed’.

By following this tutorial: https://octavainc.com/blog/cisco-sg350-switch-firmware-update-rollback-procedure/

[Flavio Miranda]

The procedure seems right. What are you worried about?

The switch is already faulty.

[GBInformatics]

What worries me is that the switch is defective even though it's 1 month old... and I've put my savings into it.

[GBInformatics]

Important information every time it loses the password configuration.

Wouldn't that be more software?

[Flavio Miranda]

Hard to say. Only after upgrading you can find out.

 You should consider talking to your employer and return It.

Is not Fair.
