SG300-10 Dead ?

Hello,

 

We tried to update our Cisco SG300-10 to latest version 1.4.8.06, since then the system is completely dead, after the upload in HTTP/HTTPS mode the switch turned off all Ethernet ports (without rebooting) rendering the web console innoperent. After a hard reboot the switch became up (System LED green and not blinking) but still, no Ethernet ports working (no LED, nothing), we then tried a hard reset (20 seconds on the reset button), and now the system is not booting anymore (System LED in an endless blinking status).

We tried a USB to Serial DB9 cable to check if there is something on the CLI console (with the good baud rate): nothing, blank screen.

 

Can we consider our switch as dead ? Is there something we can do ?

 

Thank's

Hello, 

 

I hope you are doing well. 

 

In order to determine if this is a hardware issue or not I would advise you to do the following. 

 

  1. Do the 30-30-30 factory reset
    1. With the device turned on press and hold the reset button for 30 seconds
    2. Then Unplug the switch from the power still holding the reset button for 30 seconds
    3. Then Plug the power back in still holding the reset button for the last 30 seconds
  2. Once the switch boots up connect a PC to port 1 and set up the static IP on the PC 192.168.1.10 255.255.0
  3. Try to ping to the default switch IP address 192.168.1.254

 

If successfully please proceed to do the firmware upgrade/re-flash using the software “tftpd64 or tftpd32”

 

            ** please see image attached for the tftpd32 settings
