Hi,
I did something really stupid. I deleted all the files in flash and now when the switch boot up, it cannot find the IOS to load and gives the "switch :" prompt. I was trying to boot it into ROMMON mode and copying the ios which I have downloaded over the console cable
Any ideas on the best way to get the IOS back on this switch quick smart.
Thanks a million
Anthony.

Hi Anthony,
If you are sure you have copied a new IOS over to the flash it's possible there's an old "boot system" command left in the config that is telling the switch to boot the old image file - presumably non-existant now.
If this is the case you should be able to do the following from switch: mode -
flash_init
load_helper
dir flash:
boot flash:FILE_NAME
If this boots be sure to modify the "boot system" line in the config.
Otherwise you will need to copy a new IOS over, in which case there's a guide for the 3750 at http://www.cisco.com/en/US/products/hw/switches/ps628/products_tech_note09186a0080169696.shtml
Hope this helps
Cheers

Hi Peter,
I haven't even got that far yet. I am looking for advise on how to copy the ios image from my pc to the switch (which has no ios in flash) via the console cable.
Thanks
Anthony.

Hi Anthony
He has answered your question, if you read the link it will explain how to use xmodem to copy the IOS over.
