C9200L enter mode 'switch:'

[WanisaCh]

c9200L ever factory reset all and boot image again.

Yesterday power cut. I reboot switch but switch enter mode 'switch:' again.

how to solve problem ?

[Leo Laohoo]

Put the firmware into a USB flash drive and use "emergency-install" (go straight to Step 5).

[WanisaCh]

"emergency-install tftp://192.0.2.1/cat3k_caa-universalk9.
 SPA.03.03.00.SE.150-1.EZ.bin"

what is ip address "192.0.2.1" ? i can asign? 

[Leo Laohoo]

If the firmware is in a USB flash drive, then the correct syntax is:  emergency-install usbflash0:filename.bin

[WanisaCh]

I can not use command "emergency-install" 

[Leo Laohoo]

In ROMMON, enter "?" and see what options appear.

[Leo Laohoo]

Interesting options available. 

Try this:  "boot usbflash0:filename.bin".

[WanisaCh]

I boot usbflash0:filename.bin can be used normally. But after reboot switch enter mode 'switch:' again.

[Leo Laohoo]

Ok, now show me the complete output to the command "set". 

I also need the first seven characters of the serial number.

Console into the switch and reboot. 

Post the entire bootup process. 

NOTE:  DO not post screenshots.

[Leo Laohoo]

Ok, so the switch boots up successfully. 

Now post the complete output to the command "sh boot".
