Here are the four types that I have experience with:
An 11/23PLUS in a BN-11 box that has a H9276A backplane. This *is not*
serpentine.
An 11/23 in a BN11-NC box that has a H9273 backplane. This *is not*
serpentine.
An 11/23 in an OEM box with a H9275-A backplane. This *is* serpentine.
A couple of 11/03s in BA-11M boxes with the H9270 backplane. This *is*
serpentine.
So, as Ethen, Pete and others have suggested, check everything with the
Handbook, and make sure you know which backplane you have.
If you need more numbers and a little more data, my list of backplanes
and chassis is at http://www.dunnington.u-net.com/public/PDP-11/QBus_chassis
