Connecting the Host Interface CableTo connect the host interface cables to the library:1. It is recommended that you shut down and turn OFF the associated server.Turn OFF all attached devices. Remove the power cables from the server andall attached accessories.Important: Failure to remove the power cords from these devices beforeconnecting the host interface cable could result in damage to thelibrary.2. For a SCSI library, attach one end of the host interface cable to one of theconnectors on the back panel of the library (1). For a Fibre Channel library,attach one end of the host interface cable to the connector on the back panel ofthe library (4).For a Serial Attached SCSI (SAS) connected library, attach thehost end of the SAS cable to the SAS or Mini-SAS (SFF-8088) HBA (2). Fullheight drives will have dual SAS or Mini-SAS connectors. Half height driveswill have one SAS connector. Unused SAS connectors do not need to beterminated.3. Attach the other end of the host interface cable as follows:v For a SCSI library, connect the host interface cable to the connector on theSCSI host bus adapter or to the connector on the previous device on the SCSIbus. Attach the terminator ( 3 in “Connecting the Host Interface Cable”) tothe remaining SCSI connector on the back panel of the library, if the libraryis the last or only device on the SCSI bus. Otherwise, attach one end of aSCSI cable to the remaining port and the other end to the next device on theSCSI bus. Make sure that the last device on the SCSI bus is properlyterminated.Note: Cables and terminators supporting Ultra160 should be used.Note: The host bus adapter should be LVD SCSI. A single-ended (SE) SCSIhost bus adapter will work, but will severely degrade performance,a77ug1011 342 56Figure 4-16.
