3750X "Single Switch Stack"

I have a 3750X 24 port switch (with NM-1G network module) running IOS 15.0(1). Is there any benefit or reason to plug in the included StackWise cable and loop it back to itself in a single switch installation?

I don't see any recommendation in the documentation. The data sheet indicates a single switch is a non-blocking device so I'd think there's no bandwidth advantage like there is when connecting an actual multi-switch stack and needing to close the loop for the full 32 Gbps stack bandwidth.

The only reason I can see is to keep from misplacing it.

Hmm, I wonder whether looping a single switch would confuse it.  Assuming it doesn't, considering the stack cables can bottleneck compared to the fabric, although at least StackWise+ doesn't put everything on the ring, I would think it would be inadvisable to close the ring.  However, to avoid misplacing the cable, maybe just attach to one port, i.e. don't close the ring.

Nope.  You don't get any benefit other than you know where one cable will always be.
