Connecting Internal Scsi Devices; Connecting The Scsi Ribbon Cable To The Host Adapter - Adaptec AVA-2822 User Manual

Connecting Internal SCSI Devices

Internal SCSI devices use a 50-pin flat SCSI ribbon cable with a
50-pin header internal connector. The cable has connectors at each
end and two connectors in the middle; this allows you to connect
three internal SCSI devices. To connect four or more internal SCSI
devices to a SCSI bus, obtain a 50-pin SCSI ribbon cable with enough
connectors to accommodate all of your internal SCSI devices.
Note:
Refer to the device's documentation to install and
mount internal SCSI devices inside your computer chassis.
To connect internal SCSI devices, follow these steps:
1
Attach the connector on one end of the 50-pin SCSI ribbon
cable to the 50-pin internal SCSI connector on the host adapter.
Maintain pin-1 orientation. Pin 1 of the SCSI ribbon cable is
designated by a colored stripe on one edge of the ribbon cable.
Pin 1 of the host adapter or SCSI device connector is usually
designated by an arrow, a delta symbol ( ), or a '1' on the
connector.
