I would tend to agree with Mark. You probably do not have enough
capacitance in the backplane, or you do not have an inrush(soft-start)
circuit. There are many ways to avoid this problem. Check out the
following brief in EDN
<http://www.ednmag.com/ednmag/reg/1997/121897/26di_07.htm> . This type of
circuit or, a simple MOSFET with a set RC time constant can help.

Dennis -
Your board insertion problem sounds more like an in-rush current problem
than power plane resonance. Do you have further details which would confirm
resonance over inrush?

Can some kind person please point me to some references on power-plane
resonance? I am researching for a new backplane design of an existing system
where we are having some problems with board insertion causing disturbances
on the power distribution planes.
Thanks in advance.
