Direct Access Storage Device Support Structure

      This article describes a supporting structure for a direct
access storage device (DASD) capable of storing or supporting
different sizes of media devices.

      This DASD structure can accommodate DASD devices with or
without integral (supplied with the device) bezels, media and
non-media accessible devices, (as indicated in the device
configuration chart Fig.  3), in any of four Bay locations.

      Fig. 1 isometrically displays a 3.5 inch 1/3 high in Bay 1, a
5.25 inch 1/2 high device in Bays 2, 3, and a 3.5 inch 1/2 high
device in Bay 4.

      Fig. 2 isometrically displays (2) 3.5 inch 1/3 high devices, a
5.25 inch 1/2 high and a 3.5 inch 1/2 high device.  Two devices are
shown out-of-their Bays to illustrate the electromagnetic
compatibility (EMC) direct grounding path.  Item 1 illustrates the
frame contact surface feature, Item 2 the spring contact on a common
adapter tray, and Item 3 the contact surface on the rails.

      Fig. 3 displays a chart illustrating all DASD device possible
configurations.

      A 3.5 inch 1/3 high device can be supported in Bay 4 with a
bottom mounting slide and spacer or onto an adapter tray in Bay 1,
and/or Bay 2, and/or Bay 3.  A 3.5 inch half high device can be
installed in Bay 4 with a bottom mounting slide or onto the common
adapter tray in Bays 2 and/or 3.  A 5.25 inch 1/3 high device can be
installed in Bays 1 and/or 2 and/or 3 while a half high c...
