KZPBA–CA PCI-to-UltraSCSI Host Adaptaer
3–8 EK–KZPBA–UG. B01
Figure 3–6 Connecting Ribbon Cable to a Second Internal SCSI Device
4. To connect three or more internal SCSI devices to the SCSI bus, the ribbon
cable must have enough connectors to accommodate all the devices. Plug the
connectors into the SCSI devices maintaining the pin-1 orientation.
5. If you are using both internal connectors on the host adapter, proceed in the
same fashion as above for the other cable.
3.3.2 Connecting External SCSI Devices
The preferred cabling method is a point-to-point cable connection from the
KZPBA–CA Host Adapter to the DS–BA356–XX. Up to fifteen wide SCSI
devices can be supported externally to the KZPBA–CA through carefully cabled
topologies. See the UltraSCSI Configuration Guide for more details.
The KZPBA–CA does not support daisy-chained configurations with the
KZPBA–CA in the middle of the SCSI bus attached by the external connector.
The external connector on the single-ended version of the module is a 68-pin
connector. The external connector is keyed so that it can be plugged in only one
way making the pin-1 orientation automatically correct.
Follow these steps to connect an external SCSI device housed within a
DS–BA356–XX shelf:
1. Attach one end of the cable to the KZPBA–CA host adapter (see Figure 3-7).
