Hi,

If you have any other cisco 3560G series switch then you can take ios from that switch and upload the same ios to your deleted switch,following is the procedure for the same :-

switch#sh flash

Directory of flash:/

2  -rwx          99  Feb 24 2005 11:16:03 -05:00  private-config.text
3  -rwx        8149  Feb 24 2005 11:16:03 -05:00  config.text
4  -rwx         804  Jun 10 2004 18:45:09 -04:00  vlan.dat
6  -rwx         342  Jun 10 2004 11:36:32 -04:00  system_env_vars
24  drwx         192  Jun 10 2004 11:36:23 -04:00  c3550-i5q3l2-mz.121-20.EA2
7  -rwx          18  Jun 10 2004 11:36:32 -04:00  env_vars

15998976 bytes total (8269312 bytes free)

c3550-i5q3l2-mz.121-20.EA2 is the directory that the IOS file is in

This gives you the IOS file name in the directory

switch#cd flash:/c3550-i5q3l2-mz.121-20.EA2
switch#sh flash

Directory of flash:/c3550-i5q3l2-mz.121-20.EA2/

25  drwx        2688  Jun 10 2004 11:34:50 -04:00  html
107  -rwx     4219426  Jun 10 2004 11:36:23 -04:00  c3550-i5q3l2-mz.121-20.EA2.bin
108  -rwx         252  Jun 10 2004 11:36:23 -04:00  info


15998976 bytes total (8269312 bytes free)

Next copy the IOS to the tftp server

switch#copy flash tftp
Source filename [flash:/c3550-i5q3l2-mz.121-20.EA2.bin]? flash:/c3550-i5q3l2-mz.121-20.EA2/c3550-i5q3l2-mz.121-20.EA2.bin
Address or name of remote host []? 10.1.1.1
Destination filename [/c3550-i5q3l2-mz.121-20.EA2/c3550-i5q3l2-mz.121-20.EA2.bin]? c3550-i5q3l2-mz.121-20.EA2.bin

That should complete the copy of the IOS to the tftp server when it is in a directory

Check out the below link for more information to recover or upgarde an ios to switch

and if dont have any new switch check your cisco smartnet contract that downloading an ios needs some commericial aspect involved or not.

Hope to Help !!
