     19===== PCI Module =====
    2220
    2321The CM has two components:  a CM PCI card that connects directly to the host, and a NodeIDBox that permanently mounts on a fixture at each grid position.  The PCI CM block diagram is shown in Figure 5. 
     
    2725The physical form-factor for the Chassis Manager is a 2U PCI card measuring approximately 4.75 x 2.5 in.  The Node ID box is on a board measuring approximately 2.25 x 1.75 in.  Appropriate sockets permit the RCM3700 module to plug directly into the PCI card or optionally through a 10 pin ribbon cable for remote mounting.

    8583The 256 x 8 PCF8570 I2C RAM device is included in the CM design for future use, and is not used on the initial CM boards.  Its design consideration addresses inter-processor communication between the CM and the Host node.
