Input/Output Bracket for Peripheral Component Interconnect Common
Mezzanine Card

      Disclosed is a bracket design allowing a Peripheral Component
Interconnect (PCI) host card to mechanically accept a PCI Mezzanine
Card (PMC) and provide access to the I/O connector(s) on the PMC when
the combination is installed in a computer system.

      The PMC currently being standardized (IEEE P1386.1
Specification) is designed to mate with a wide variety of host cards.
Examples are VME64, Multibus I, Multibus II, and Futurebus+ host
cards.  Mating mechnaism and mounting brackets are specially designed
for these host cards to accept a PMC.

      A PCI card with its unique layout inserts to a bus slot in a
computer system with a bracket at the end to provide mechanical
support, access to I/O connector(s), and EMI shielding.  The PMC has
fixed dimensional parameters and bezel shape which are being
standardized by IEEE.  When a PMC is used in conjunction with a PCI
host card as shown in Fig. 1, a special bracket (Fig. 2) with two
right-angled tabs to secure the PMC to the PCI, and a cut out to
allow access to the PMC are needed.  The design provides the
necessary mechanical support, access to I/O contector(s), EMI
shielding, and ease of installation of the PCI/PMC combination to a
computer system.  In addition, the specially designed bracket can
accommodate any PMC that complies with the IEEE specification.
