SCSI CHANNEL CONFIGURATIONS
Termination of the SCSI Bus at the VHDCI Connectors
Ultra320 I/O Repeater Module
CAUTION:
VHDCI connectors are easily damaged by improper handling. Visually
inspect each connector for bent contacts and carefully align prior to
insertion.
NOTES:
Port-A (In) connects to SCSI Host/Disk Channel.
Port A (Out) connects to a terminator or daisy-chained to another Info-
Station chassis or SCSI device.
For SCSI Ultra320 operation, the InfoStation requires Ultra320 drives,
Ultra320 HBA, Ultra320-compliant cabling (internal and external), and
Ultra320 repeater modules installed.
For daisy-chaining applications, total device-to-host cable length must not
exceed 12m (approx. 39ft) per SCSI specifications.
