Hi Edmond,

Can you do "sh sysinfo" on your WiSM and post the output please?

We have tried to shutdown the GigabitEthernet ports on the Chassis which is the Port-Channel to the Controller.

But if I start the FTP transfer for the upgrade over the Service Port , the same error message appears and the

download didn't start.

I *think* (emphasis on the word "think") the problem is your Bootloader Version (3.2.202.0).

Can you try upgrading the bootloader version in the following sequence:

4.1.171.0 ER

4.2.61.0 ER

4.2.112.0 ER

and finally the version where you are running your current firmware.

By the way, ER stands for Emergency Release. It's actually a "patch".

Note: The final "true" bootstrap version is 4.2.112.0 ER. Which means if you upgraded the bootstrap to 5.X, when you do a "sh sysinfo", the bootstrap will always report as 4.2.112.0.

How you were able to upgrade your firmware to version 5.X with a 3.X bootstrap is strange.
