SCSI to SCSI RAID Subsystem
36
User Manual
7.
Attach a SCSI terminator to the other SCSI Host Channel connector (Host
Channel A Out port). Make sure to tighten the lock screws of the SCSI
terminator.
8.
If you want to configure subsystem into multi-host attachment, connect another
host system using the other external SCSI cable to the other SCSI Host Channel
(B).
NOTE: When one or more SCSI devices are connected, the total
length of all cables (internal or external) must not exceed 3
meters (9.8 ft.) to ensure reliable operation.
IMPORTANT: For safety reasons, make sure the Disk Array and
Host Computer are turned off when you plug-in the SCSI cable.
3.2 SCSI Termination
Two 68-pin wide SCSI connectors are provided on the back of the enclosure. These
connectors are used in one of two ways:
If the RAID subsystem is the only external SCSI device, or is the last external
device in a daisy-chained configuration, connect the incoming SCSI cable (the
one which is attached to the SCSI adapter) to the Host Channel A & B In
connector and install the external SCSI terminator on the Host Channel A & B
Out connector.
If the RAID subsystem is to be placed in the middle of a daisy-chained
configuration, connect the incoming SCSI cable (the one which is attached to
the SCSI adapter) to the Host Channel A & B In connector and connect the
outgoing cable (the one which continues on to other devices) to the Host
Channel A & B Out connector. In this case, no terminator is required in the
RAID subsystem but the last device in the daisy chain must have a terminator.
