Connecting the Host Interface Cable
To 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 and
all attached accessories.
Important: Failure to remove the power cords from these devices before
connecting the host interface cable could result in damage to the
library.
2. For a SCSI library, attach one end of the host interface cable to one of the
connectors 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 of
the library (4).For a Serial Attached SCSI (SAS) connected library, attach the
host end of the SAS cable to the SAS or Mini-SAS (SFF-8088) HBA (2). Full
height drives will have dual SAS or Mini-SAS connectors. Half height drives
will have one SAS connector. Unused SAS connectors do not need to be
terminated.
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 the
SCSI host bus adapter or to the connector on the previous device on the SCSI
bus. Attach the terminator (

in “Connecting the Host Interface Cable”) to
the remaining SCSI connector on the back panel of the library, if the library
is the last or only device on the SCSI bus. Otherwise, attach one end of a
SCSI cable to the remaining port and the other end to the next device on the
SCSI bus. Make sure that the last device on the SCSI bus is properly
terminated.
Note: Cables and terminators supporting Ultra160 should be used.
Note:
The host bus adapter should be LVD SCSI. A single-ended (SE) SCSI
host bus adapter will work, but will severely degrade performance,
