DRM-7000 Operating Instructions
SCSI buses allows duplicate SCSI IDs as long as the duplicates are assigned to separate
buses.
Even if none of the drives installed within the changer has been assigned the same SCSI ID, it
is necessary to assign a different SCSI ID to any drives which share the same ID with other
devices such as hard drives on the same bus.
4.5 Connecting SCSI Cables
Confirm that all drives have been installed, before connecting the SCSI cables. Check that all
conditions listed below are met below attaching the cables.
• The total combined length of all SCSI cables must be less then six meters, including
the internal cables.
• Installing seven or more drives, or when creating separate daisy chains for fewer than
seven drives, requires a separate multi-drive connector panel.
• Turn OFF the power to the Changer and to the host computer before connecting the
SCSI cables.
• After connecting the cables, turn the Changer ON
before turning the computer ON.
• The Changer is unable to recognize faulty SCSI connections or SCSI ID assignment
mistakes.
• Reboot the DRM-7000 after installation new or replacement drives to ensure the
system recognizes all existing drives.
Examples of SCSI cable connections:
Daisy-chain two internal readers and a
recorder then connect to the Changer
Daisy-chain four internal readerse and a
recorder then connect to the Changer –
requires a cable for two drives
