Cage Mounted Direct Access Storage Device Sleeve

      Disclosed is a Direct Access Storage Device (DASD) sleeve that
allows for individual removal of two DASD.  The sleeve is installed
in a cage in lieu of two books.

      The DASD sleeve, shown in the figure, is an adapter that fits
in two book slots in the cage of an AS/400* computer.  It
accommodates two DASD carriers that can be removed individually
without disrupting the operation of the remaining DASD.  This ability
is essential to perform concurrent maintenance (work performed
without powering down a computer).  The sleeve provides sufficient
alignment and guidance to allow the DASD carrier to connect directly
with the system backplane.  Additional cabling or circuit boards are
not required.  The sleeve bolts to the top and bottom rails of the
cage for stability.  Two DASD can then be slid into the sleeve's
openings and secured.  The front of the Sleeve features an
electromagnetic interference (EMI) shield that pivots at the bottom.
The pivoting feature ensures the shield will not be forgotten or
lost.
