Installing SCSI Cables, Jumpers, and Terminators
Follow the steps on the following pages to connect your library to the SCSI bus. This involves installing SCSI cables, terminators (s) and jumpers (daisy chain cables) onto the SCSI connectors at the rear of the library.
Note
∙Make sure that the interface cable(s) you are planning on using have the appropriate connectors on each end. If the host computer's SCSI connector is different from that on the your library, you will need to obtain an adapter or a different cable. Consult your dealer or adic Customer Assistance if you need help.
∙The interface cable(s) must be shielded – adic can supply you with the correct type(s).
Determining Your SCSI Configuration
The Scalar Library can consist of up to five SCSI devices; four drives and the library. Listed below are the SCSI configurations supported by the library:
●Connection to up to five SCSI interface channels (buses) are allowed.
●The SCSI buses can be either
●Each tape drive and the library robotics can be connected to separate SCSI buses, or up to four drives and the robotics can be connected to the same SCSI bus.
●A device (drive or robotics) can be connected to more than one SCSI bus when integrated into a multi- initiator environment.
●Termination can be active or passive. adic recommends using active termination on a
●All termination must be external. Never use internal terminators to terminate the drives.
Note
SCSI bus TERM POWER is supplied by the robotics interface, not by the drives. This can be modified. Please call adic Customer Assistance if you need to change this.
