It is a little smaller than the chassis, but not by much.  One would assume that it would give access to the bottom of the circuit board, and it does.  But there are no apparent adjustments that one needs to do, I think.  What is the purpose of this panel?

It may be there to close an otherwise big hole in
the bottom of the chassis.  I don't mean that
sarcastically either.  The manufacturer may have
needed access for assembly and test.
