Device Power/Logic Assembly

       The disclosed device will accomplish simultaneous
plugging for both power and logic cards within a chassis by combining
individual field replacement components into a single modular
package.  The device consists of a logic card cassette 1 and power
card cassette 2 plus associated cable connectors and fasteners (Fig.
1).

      The logic card cassette consists of a logic card 3 fastened
between an upper card housing 4 and a lower card housing 5 by using a
multiplicity of fasteners 6 around the periphery of the card (Fig.
2).  Each housing is molded from electrostatic dissipative plastic to
protect static-sensitive logic modules soldered to the card.  Also
soldered to the logic card is a DC input connector 7 which attaches
cables 8 directly to the power supply and distributes current to the
logic card.  Other connectors include the channel cable I/O
connectors 9 for attaching cables to the processor and logic cable
signal connectors 10 for cables connected to other I/O devices in the
frame.

      The power cassette (Fig. 2) consists of an upper housing 11 and
a lower housing 12 to which the power supply card 13 attaches using
screws 14.  These sheet metal housings also fasten together using
screws 14 and provide strength and rigidity to the package as well as
protection against EMI (electromagnetic interference) noise within
the package.  An AC connector 15 is located on the power supply
housing and is allowed to float or...
