Hello, @balaji.bandi thank you for your help I have 

tried to turn off the switch for 10 minutes 

and I turn it on again it's showing the same issue loop booting, also I have tried The Mode button when the switch boot up but - it's the same 

please see attached video of booting 

[balaji.bandi]

it should work - we have done many. (step 4 is very important )

SUMMARY STEPS

1.    Connect a terminal or PC to the switch.

2.    Set the line speed on the emulation software to 9600 baud.( Configure the PC or laptop terminal emulation software for 9600 baud, 8 data bits, no parity, 1 stop bit, and no flow control.)

3.    Power off the switch.

4.    Reconnect the power cord to the or the active switch. Within 15 seconds, press the Mode button while the System LED is still flashing green. Continue pressing the Mode button until all the system LEDs turn on and remain solid; then release the Mode button.

Hello,

on a side note, it looks like all your LEDs are amber, meaning all LEDs signal a fault ? It could very well be that your device is toast, and you need to return it...

@balaji.bandi thank you i have done those steps very carefully but there is nothing it's the same issue 

loop boot as the video i have post before 

@Georg Pauwen @balaji.bandi

I may be thinking if you done that steps very carefully, then time to raise an ticket with TAC for RMA. (if you have contract)

[Hazem.hussain]

@balaji.bandi if i don't have a contract with them then what 

and is it possible to fix this issue only using software or it's hardware issue and they have to fix it not me 

[balaji.bandi]

You need to have contract for cisco to replace. (cisco come with only 90days warranty)
