Cisco 3850 stacking H/w Version mismatch

[Kurt Warner]

I have a failed cisco 3850. I got a new switch in and the IOS was lower than my current stack so i upgraded it . When i do a show ver the IOS looks right but when i do a show switch the H/W version are different.  This will cause my stack to fail ? 

New switch :

Switch Ports Model              SW Version        SW Image              Mode

------ ----- -----              ----------        ----------            ----

*    1 56    WS-C3850-48P       03.07.03E         cat3k_caa-universalk9 INSTALL

                                                                 H/W   Current

Switch#   Role    Mac Address     Priority Version  State

------------------------------------------------------------

*1       Active                                     15           V04     Ready

Old Switch :

Switch Ports Model              SW Version        SW Image              Mode

------ ----- -----              ----------        ----------            ----

Hi Kurt,

That will not cause the stack to fail, you just need to make sure that the IOS version and the license level are the same between the stack members and make sure to power down the new switch before connecting it into the stack.
