  • Page 19: Ide Interface (Cn1 And Cn3)

    The CN1 and CN3 connectors are routed to the 1-P3 connector for connection of IDE devices such as hard disk drives and CD-ROM drives. When using Advantech’s 6U-sized processor module, users can connect IDE devices to the backplane, instead of direct cabling to the processor board.

    2.4 Floppy Disk Interface (CN4) The CN4 connector is routed to the 1-P3 connector for connecting floppy disk drives. With Advantech’s 6U-sized processor module, users can connect floppy disk drives to the backplane, instead of direct cabling to the processor board. This shortens the MTTR for replacing the processor board.

  • Page 26: Ground Configuration

    2.8 Ground Configuration Along the top and bottom of the MIC-3451/MIC-3451H are 24 mounting holes. The holes are arranged in an alternating pattern of chassis (frame) grounded pads and logic grounded pads. The square pad holes are connected to chassis ground, and the round pad holes are connected to logic ground.

    0 Ω resistors, the clock routing can be reconfigured to comply with the earlier CompactPCI Specification, PICMG 2.0, version 2.1. Reconfiguring the backplane to comply with this earlier specifica- tion allows the MIC-3451 to be backward compatible with CPUs using shared clocks. Individual Clock CPUs (MIC-3451H)
