[TenTec] HP Z3801 rack mount

[Eric Scace K3NA <eric@k3na.org>]

   My HP Z3801 arrived recently.  The front panel is 10.5 in wide and 4 in 
high, with a thumbscrew on the left and right edges at
mid-height.  I assume there must be some kind of standard rack-mount shelf + 
panel into which the unit is inserted in order for it
to live in an equipment rack.  Does anyone know if this is a correct 
assumption?  If so, where does one acquire this rack-mounting
system?

   Thanks.
