IOS Upgrade on Catalyst 3750

Hi,

I tried to install a new ios, but the boot process was interrupted:

Boot:

Loading "flash:/c3750-ipservicesk9-mz.122-55.SE.bin"...@@@@@@@@@@@@@@@@@@@@@@@@@.....@

Error loading "flash:/c3750-ipservicesk9-mz.122-55.SE.bin"

is it possible, that there is not enought space?

What happends if i delete the old file ( c3750-ipservices-mz.122-35.SE5) and it won't work?

Can i restore this file in the "debug" modus?

Thanks for your help.

with friendly greetings,

Manuel

Re: IOS Upgrade on Catalyst 3750

Firstly, you'll need to delete the old IOS using the command "delete /f /r flash:c3750-ipservices-mz.122-35.SE5".

Next, if this is a one-and-only switch then you can copy the IOS into this switch using the command "archive download-sw tftp:///.tar".

Hope this helps and don't forget to rate our useful posts.  Thanks.

Re: IOS Upgrade on Catalyst 3750

Thanks for your fast answer.

But im not 100% sure if it works.

Because i haven't got a Tar file, only the bin file.

I will add the boot ios with the command Boot system flash .

What can i do if the switch can't boot?

How can i restore the old ios in the worst case?

If that's the case, copy the .bin file using the command "copy tftp: flash:".
