Abstract

Internal connectors on Input/Output (I/O) adapter boards present an added degree of complexity when installing cards. This added complexity is compounded when mechanical hardware is provided for inserting and removing add-in boards without removing the system covers. This article describes means to automatically insert and remove the boards (without removing the system covers), while also providing means to connect the internal cables to the add-in board.

Mechanism for Inserting Input/Output Cards with Bottom-Card Input/Output
Connectors

      Internal connectors on Input/Output (I/O) adapter boards
present an added degree of complexity when installing cards.  This
added complexity is compounded when mechanical hardware is provided
for inserting and removing add-in boards without removing the system
covers.  This article describes means to automatically insert and
remove the boards (without removing the system covers), while also
providing means to connect the internal cables to the add-in board.

      The Figure illustrates an I/O board such as a Peripheral
Component Interconnect (PCI) add-in board, which has provision for
connection of cables to the board internal to the machine.  Internal
cables are required for devices such as Small Computer System
Interface (SCSI) adapters, which in turn connect via the internal
cables to components within the system.

      In the Figure, the mating half of the I/O connector is mounted
on the I/O board on the same side of the board as the PCI connector.
The mating half of the I/O connector that attaches to the cable is
physically mounted to (or through) the system board with the cable
connected to the connector from the back side of the system board or
from another connector site on the top side of the system board.

      The I/O board is inserted into the system in the direction
shown in the Figure, and the board is then inserted into the PCI
connector, as shown. ...
