CAT6500/SUP720-3BXL IOS Query


I've been trying to track down a particular feature on Cisco's Feature Navigator and have come up with a question, is it possible to run a 7600 IOS on a SUP720-3BXL when in a 6509 Chassis?

Fundamentally the Supervisor engine is the same and I could pick it up and move into a 7609 chassis (if I had one...).

I suspect there will be a logical reason why I can't but wanted to check first.

Thanks in advance.

I believe the 7600 IOS will refuse to run on the 6500 platform.

It depends on the version you are trying to boot. Older versions id not have a chassis check and could be used on 6500 as well. Now, with later releases, you would see a compatibility error and it won't boot:

%C6K_PLATFORM-1-DISABLE_NON_C7600_CHASSIS: Software has detected an attempt to run a 
c7600 image on an incompatible chassis ([char]). This image may not boot.
