Replacement Member Switch Won't Join 3850 Stack

[netops009]

Hi.

I'm replacing a bad switch in our 3850 stack.  It's switch 3 and as far as I can see has the correct software version but I get this error:

V-Mismatch.

New switch - 

Switch Ports Model SW Version SW Image Mode
------ ----- ----- ---------- ---------- ----
* 3 56 WS-C3850-48P 03.03.01SE cat3k_caa-universalk9 INSTALL

Current Stack - 

3 56 WS-C3850-48P 03.03.01.SE cat3k_caa-universalk9 BUNDLE

Can anyone help?

Thank you,

Thomas

Hey Thomas

run the command software auto-upgrade enable then reboot the switch just the switch in question reload slot x that should make it join the stack when it reboots
