4. Installation of internal SCSI cables
The INI-9100U has one 50-pin internal SCSI bus connector and the
INI-9100UW has two internal connectors: one 50-pin flat ribbon SCSI
connector, and one 68-pin high density ultra wide SCSI connector;
both internal connectors may be used in tandem or singularly,
depending on your bus configuration. Installation of internal SCSI
cables must be performed before replacing the system covers. The
internal ribbon cable is made with multiple connectors attached and
used to daisy chain the host adapter with two or more devices. It is
important that the cable installed correctly for proper operation. The
cable has a colored stripe running the length of the cable, on the edge
distinguishing the pin one side of the connector. These identifying
markings must match when mated on the host adapter board.
When attaching ultra wide SCSI internal devices, use the 68-pin high
density wide SCSI internal cable connector. This connector, identified
by J4 on the host adapter (refer to figure 3-2), is keyed for proper
orientation and connection. Insert on end of the internal wide ultra
SCSI cable into the INI-9100UW host adapter and the other
connectors in a similar fashion into your ultra wide SCSI connectors
as described in the appropriate manufacturers instructions.
When attaching ultra SCSI devices, use the 50-pin ultra SCSI cable
connector, identified by J1 on the host adapter (refer to figure 3-4).
This connector has a triangle marking that identifies pin-one. Align
the internal cable into the host adapter and the other cable connectors
