You will need to upload a new IOS.   Cisco has the document right here that explains step by step how to do that: http://www.cisco.com/en/US/products/hw/switches/ps663/products_configuration_example09186a0080094ecf.shtml

Hi
Thank you for all reply. Please I recover the imageand the switch work  but I have another problem now. The switch have two supervisor the original now it's working and standby supervisor its not work now. When I check using show bootvar for original supervisor I get below information

BOOT variable = bootflash:cat4000-i5k91s-mz.122-20.EW.bin,1
CONFIG_FILE variable does not exist
BOOTLDR variable does not exist
Configuration register is 0x2042

((Standby supervisor is not ready.))

and when I check the standby supervisor using dir bootflash :

I get

rommon 10 >dir bootflash:

   File size                  Checksum      File name
   --------------------------------------------------

   Total space = 59244544 bytes, Available = 59244544 bytes

Please do I need to upload IOS to the standby supervisor? And if yes can I copy the IOS from original supervisor and how I can do that

Regards

Take a look at http://ciscosystems.com/en/US/docs/switches/lan/catalyst4500/12.2/25ew/configuration/guide/RPR.pdf - this has all the information you need to configure your standby supervisor.

Good Luck
