Connecting the SCSI
Bus Cable
(SAITe1300-S only)
Connect the SAITe1300-S (SCSI model) and the host
computer with a SCSI cable. This section describes how
to do so. Use an Ultra 160/m SCSI LVD cable
commonly sold in stores to connect the unit to the SCSI
bus. The SAITe1300-S uses a 68-pin half pitch
connector.
Caution
• Do not connect the SAITe1300-S to a HVD (High
Voltage Differential) SCSI bus. If you do, the unit or
other devices on the SCSI bus may be damaged.
• Turn off all the connected devices before connecting
the SCSI cable, including the SAITe1300-S and the
host computer.
• If the SAITe1300-S is the last or only device on the
SCSI bus, make sure that you connect the supplied
terminator to the open connector.
• Make sure that the SCSI connectors are securely
connected.
• With LVD (Low Voltage Differential) SCSI, make the
total length of the SCSI cable (internal and external)
connecting the host computer and the device at the end
of the SCSI bus shorter than 12 m (39.4 ft.). On an
LVD bus with a single device, make this length shorter
than 25 m (82 ft.). The SAITe1300-S internal cable
length is 25 cm (9.8 in.).
• SCSI cables cannot be branched.
1 Make sure that the host computer and the
SAITe1300-S are off.
2 Connect the SCSI cable and terminator as shown
below.
The SCSI cable can be up to 24.7 m (81 ft.) long.
(The SAITe1300-S internal cable length is 25 cm
(9.8 in.).)
A SCSI bus allows you to connect up to fifteen
peripherals to the host computer, including the unit.
When the SAITe1300-S is one of several
devices on the SCSI bus
1 Turn off all SCSI devices on the SCSI bus,
including the SAITe1300-S.
Caution
When connecting or disconnecting a SCSI cable to
SCSI devices (including the SAITe1300-S), turn off
all the SCSI devices. Failing to do so may result in
damage.
2 Connect the SCSI cable to the next device on the
SCSI bus, connect the terminator to the last device
on the bus, then issue the host command to resume
operation.
Notes
• The total length of the SCSI cables between the
host computer and the last device should be less
than 12 m (39.4 ft.). (The SAITe1300-S internal
cable length is 25 cm (9.8 in.).)
• If the SAITe1300-S is the last device on the SCSI
bus, make sure that you connect the supplied
terminator to the open connector.
