    LED cable to your SCSI host adapter. This connection causes the front panel LED to indicate activity on the SCSI bus. An LED is also on the PCI-SC896 host adapter, which indicates activity on the SCSI bus. The Busy LED connector J6 is not keyed. The J6 connector is a 4- pin one row right angle header for both channel A and channel B.
  • Page 18: Making External Scsi Bus Connections

    This section provides step-by-step instructions about making external SCSI bus connections: 1. If you need to connect external SCSI devices to the PCI-SC896 host adapter, plug the 68-pin high-density connector on one end of a shielded external high density cable into the host adapter connector J2.
  • Page 19: Internal Scsi Connections

    If only internal SCSI device connections on your host adapter have been made, then terminate the last internal device on the SCSI bus. You must disable the termination on all other devices. Termination on the PCI-SC896 host adapter is automatically enabled in this case.
