Concurrently Maintainable Electronic Storage Expansion Unit

      Disclosed is the design of a system that is capable of
accommodating a variety of devices without impacting cooling and
maintenance.  Modular guides provide the means to package Direct
Access Storage Devices (DASD), Removable Media, or Electronic
Modules.  The Electronic Expansion Unit, shown in the Figure, is
secured to the top of the Base Machine.  It is made up of three
essential elements: a wrapper, a guide, and a remote blower.

      The wrapper is an upside down "U" shaped painted sheet metal
structure.  The sides and the top are made out of one piece of sheet
metal formed around various internal stiffners.  The bottom edges
have two sets of tabs that interface with the Base Machine to ensure
alignment.

      The guide is the element that contains the electronics.  It can
accommodate DASD, Removeable Media, or electronic modules.  Each
guide features identical mounting interfaces so that any combination
of two guides can be installed in the system.  The guides are mounted
directly on top of the Base Machine - one at the front and one at the
rear.

      The remote blower is installed in the system blower housing
located in the rear of the Base Machine directly below the rear
guide.  This location allows for blower maintenance without
interfering with the electronics in the Expansion Unit.
