Below is how my switch comes up, all that it will do is listed below. Please tell me how to copy from the tftp server to a switch while it is like this. Thank you in advance.

Hello Mark,
The below link will give you a good idea on how to copy an ios image to the switch and boot to a valid image.

Hope this helps.

Kirin, I checked the link that you sent, and it works, if the switch is operational. I am unable to get the switch to ROMMON mode or to bring it up so that I can copy to the switch. Someone removed the c2960-lanbase-mz.122-35.SE5.bin file from my flash. Since it doesnt have a flash to load, it is missing the greater part of what I need. Can you give me a step by step for when this is the case. Thank you.

Bump for help.

Mark,
If it's not booting to rommon, can you paste in what is happening during post?

Power off your switch.
Hold down the Mode button.
Power on the switch (continue to hold down the Mode button).
Wait for about 15 seconds and let go of the Mode button.
Your console screen should appear "rommon1>".
Type the following command (no particular order): "init_flash" and "load_helper"
Then do the IOS recovery using ROMmon download.

Or, we could just press Ctrl+break ( could have to be done multipel times) as soon as the switch boots up to get into the rommon prompt and from there on it is an easy take.

This is what comes up when I hold the MODE button down for 15 seconds.
This also comes up if I let it go without pressing the mode button. thanks.

Hi Mark,
Did you invoke the following command: "flash_init" and "load_helper"?
03-16-2010 08:41 PM
Mark,
Without pressing any MODE button on the switch, power the switch back up and then immediately press Cntrl+break multiple times. Did you try this method as well? This should surely work.

Initialising the flash will only work if that flash file is valid. If there is an issue with it, such as it being corrupt etc then you
wont be able to boot with the process mentioned.
The onyl way you can do this is via xmodem. You will need a console to the switch and have the flash file you want to boot to on your laptop

I had to work on this the weekend when I wiped out all my flash files on my switches when trying to stack 3750 with older IOS versions when powered on - painful experience!

I typed this at the switch: prompt - format flash:
I reloaded and then I was able to xmodem the image to the switch.
