How to Connect an External Unit
Connection between External Hard Drive Unit Z1 and System
Unit has to connect directly (Extension by SCSI cable cannot be
performed), and can constitute a maximum of two External Hard
Drive Unit Z1s and two External Device Bay Unit Z1s per System
Unit.
External Hard Disk Unit Z1 and External Device Bay Unit Z1
cannot connect into the same SCSI bus.
In this case, separate SCSI bus for External Hard Drive Unit Z1
and External Device Bay Unit Z1, and prepare two SCSI buses.
When the user connects two External Hard Drive Unit Z1s, they
have to select whether PCI card with more than 2ch SCSI I/F, or
combination of SCSI Riser card and PCI card with 1ch SCSI I/F.
Anyway have to connect direct using two SCSI cables.
External Device Bay Unit Z1 can only connect System Unit via
backside SCSI connector. A SCSI riser Card is needed
consequently.
