cisco 3850 stackpower issue

[Volodymyr Khrystenko]

Hello.

I have 5 switches 3850. I want to powerstack it. I read currently only 4 switches are allowed((( I upgraded switches to  Version 03.03.03.SE. I tried to set stack of 5 switches but log was generated:

%PLATFORM_STACKPOWER-3-INVALID_TOPOLOGY: Invalid power stack topology observed by switch 4. More than four switches are connected in ring topology

Can anyone say whether I connect switches incorrectly or I can do nothing for now?

Thanks

You can physically connect up to nine (9) 3850 when you use XE IOS 3.2.0 and later but you can only power stack up to four (4) units together.

And what should I do with fifth? Leave it standalone?

You can either leave it at stand-alone or break up your power stack into two:  power stack three together and power stack the last two together.

The decision is all yours.  I present you the options.  :D
