KZPCM PCI–to–Dual Channel Ultra SCSI and 10/100MB Ethernet Host Adapter

Figure 2–6 Connecting the 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.

2.5.3 Connecting External SCSI Devices

The preferred cabling method is a point-to-point cable connection from the KZPCM Host Adapter to the BA356. Up to fifteen wide SCSI devices can be supported externally to the Host Adapter through carefully cabled topologies. See the Ultra SCSI Configuration Guide for more details.

The KZPCM Host Adapter does not support daisy-chained configurations with the Host Adapter in the middle of the SCSI bus attached by the external connector.

The external connector on the module is a 68-pin VHDCI 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 BA356 shelf:

1.Attach one end of the cable to the KZPCM Host Adapter via the bulkhead connector (Figure 2–7).
