Help, corrupted image on Cat 3550

Hi, i have a cat3550 which i've done a format on the flash. after doing so, i put in the image which is c3550-i5q3l2-mz.121-9.EA1c.bin using xmodem. afterthat, i typed boot and it boots into the image but when i reload the switch, i didn't work and went to the switch: prompt giving me an error:-

The system is unable to boot automatically. The BOOT

environment variable needs to be set to a bootable

image.

this is what i see on the environmental setting:-

switch: set

?=

BOOT=c3550-i5q3l2-mz.121-9.EA1c.bin

CONFIG_FILE=c3550-i5q3l2-mz.121-9.EA1c.bin

Re: Help, corrupted image on Cat 3550

By default, the switch attempts to automatically boot the system using information in the BOOT environment variable. If this variable is not set, the switch attempts to load and execute the first executable image it can by performing a recursive, depth-first search throughout the Flash file system.If the BOOT variable is set but the specified images cannot be loaded, the system attempts to boot the first bootable file that it can find in the Flash file system.

However, you can specify a specific image to boot.

Step 1

configure terminal

Step 2

boot system filesystem:/file-url

used to Configure the switch to boot a specific image in Flash memory during the next boot cycle.

For filesystem:, use flash: for the system board Flash device.

For file-url, specify the path (directory) and the name of the bootable image.

Step 3

end

Step 4

show boot

The boot system global command changes the setting of the BOOT environment variable.

During the next boot cycle, the switch attempts to automatically boot the system using information in the BOOT environment variable.

Try setting the environment variables again using the following command.

set BOOT filesystem:/file-url ...Boot Loader Command

or the boot system filesystem:/file-url...IOS Global Configuration Command

Hope this helps you to resolve your issue.
