Hi, I am running a 3750E-48PD switch with firmware 15.2.SE1 UniversalK9 firmware as a master and I want to stack to a 3750G-16TD currently running 12.2(35)SE5 IP-Base. When i try to stack them I get a "booting in mismatch mode" and then it hangs. I understand the versions should match, but there is no UNIVERSAL version for the 3750g-16TD Switch. What can I do to make the stack work?
Thanks for any help.
