The first portion includes one or more pairs of rails and the second portion includes one or more guide blocks configured to slidingly engage the rails. The opening formed in the circuit board allows the rails to be accessed and also allows heat from the module to be dissipated down into the first portion and then into a heat dissipation structure secured to the first portion.08-01-2013
