    Run Ultra3 Devices at Ultra2 Data Transfer Rates To run at Ultra3 data rates (160 MB/s on a 16-bit bus), parallel protocol request (PPR) must be enabled. If PPR is not enabled, then the maximum data transfer rates available will be Ultra2 (80 MB/s on a 16-bit bus). Attention: Use this procedure when connecting either a 2104 Model DL1 or a 2104 Model TL1 Expandable Storage Plus system.
  • Page 27: Enable Ultra Speed (On External Devices) During Single-Ended Operation

    Enable Ultra Speed (on External Devices) during Single-Ended Operation When the SCSI adapter detects any external single-ended devices on the SCSI bus, it defaults to 10 MHz operation. Use this procedure to override the default speed and run at the Ultra signalling rate of 20 MHz (40 MB/s on a 16-bit bus). To enable Ultra speed on external devices during single-ended operation, do the following: 1.

  • Page 37: Setting Scsi Addresses

    Setting SCSI Addresses Each SCSI device requires a different SCSI address. The address is a number from 6 through 0 for 8-bit devices, or from 6 through 0 and 15 through 8 for 16-bit devices. If two SCSI devices have the same address, your system does not function correctly. SCSI address 7 is reserved for the adapter, so additional SCSI devices can be set to addresses 6 through 0 and 15 through 8.
