IOS upgrade

We use CW2K (RME ver.3.5) for the IOS upgrade of c2950 switches. All the c2950 switches with IOS 12.1(13)EA1 were failed but others with IOS 12.1(12c)EA1 were OK. What does cause this problem? Is there any work around?

Below is a Job Browser output:

Re: IOS upgrade

Is IDU7 installed for RME 3.5?

Re: IOS upgrade

No, it's not. The latest is IDU 5.0


Re: IOS upgrade

Then install IDU7 first and then try the upgrade again.
