  • Page 21: I/O Interfaces

    I/O Interfaces I/O Interfaces The main Challenge I/O subsystem consists of one or more IO4 boards, which plug directly into the Ebus and use optional mezzanine cards. Mezzanine cards are daughter boards that plug into IO4 boards to allow expansion and customizing. See Appendix D for additional information on mezzanine boards.

  • Page 22: Flat Cable Interface

    Chapter 1: Introducing the Challenge Deskside Servers Flat Cable Interface The IO4 contains two FCI interfaces that are proprietary to Silicon Graphics. FCIs are synchronous, point-to-point interfaces that allow communication between devices connected by a cable. The FCI is used to connect to the VME64 bus adapter.

  • Page 23: Scsi-2 Interface

    I/O Interfaces SCSI-2 Interface The IO4 contains two 16-bit SCSI-2 device controllers. Each controller can operate with a bandwidth of up to 20 MB per second and can be configured for either single-ended or differential operation. To accommodate extra SCSI channels, optional SCSI mezzanine cards contain three 16-bit SCSI-2 controllers.

  • Page 24: System And Scsi Backplanes

    The enclosure comes with an 11-slot cardcage and backplane that includes five VME expansion slots. Note that only two VME slots are available when a POWER Challenge system uses the optional visualization console. To the right of the cardcage is room for seven half-height (or one half-height and three full-height) SCSI devices.

  • Page 96: Using The System Controller

    Chapter 5: Having Trouble? Using the System Controller The System Controller has three basic operating modes: • It acts as a control conduit when directed by an operator to power off or boot up the system. It actively displays a running account of the boot process and flags any errors encountered.

  • Page 97: The Power-On Process

    Using the System Controller the operator from repeatedly applying power when an overvoltage condition exists. The Power-On Process You can monitor the boot process when you power on the system by watching the System Controller.
