SCSI Disk Jumper Definitions
Atlas IV, Atlas V, Atlas 10K, Atlas
10K II, and Atlas 10K III
Maxtor (formerly Quantum) SCSI disk drives have
multiple jumper setting options and are used to set specific drive features. The
most common settings are used to define the drive SCSI ID and bus termination.
Maxtor SCSI drives have additional jumper settings used for optional features
found on the drive. Listed below are the various jumper options that may be
found on Quantum SCSI drives and the corresponding feature that they enable.
DS - Delay Spin
This will cause the drive to not spin unless it receives a start unit command
from a SCSI host. Most SCSI host adapters have the start unit command enabled by
default in their BIOS. Enabling Delay Spin is only necessary when you are
starting multiple SCSI devices at power on.
NW - No Wide
Allows for 16-bit or 8-bit data transfers. With a jumper installed on the No
Wide pin pair, SCSI data bus transfers can be limited to 8-bit (narrow)
operation.
SCSI ID
All SCSI devices must have an individual ID on the SCSI bus (there is no Master
or Slave in SCSI). Four pairs of pins - A0, A1, A2, A3 - will allow
configuration of SCSI ID's 0 to 15. SCSI ID 7 is usually reserved for the SCSI
host adapter.
SE - Force Single Ended
Operation
LVD drives are multi-mode capable, which means they support operation in LVD or
single-ended (SE) mode. When an LVD device is installed on a single-ended SCSI
bus it will electrically revert to single-ended mode automatically. With most
system configurations it is not necessary to install this jumper.
SS - Stagger Spin
This option works in conjunction when the DS jumper is installed on the drive.
It will allow each device to start (spin up) at pre-determined, staggered
intervals when a START UNIT command is sent by the host adapter. This is useful
when operating multiple devices on the same SCSI bus (helps prevent power supply
overload caused by multiple devices attempting to start concurrently). Current
host adapters usually offer a START/SPOP UNIT command enable or disable.
TE - Termination Enable
The Atlas IV, Atlas V, Atlas 10K, Atlas 10K II, and Atlas 10K III drives are
Ultra160 Multi-Mode LVD devices and do not support onboard termination. It is
recommended that a 68-pin twisted pair SCSI cable with a LVD/SE multi-mode
terminator be used.
TP - Termination Power (Differs from
Termination Enable)
Termination Power ensures that there is a sufficient level of power along the
entire SCSI bus. It is recommended that the last device on the SCSI bus have the
Termination Power jumper installed. All intermediate devices on the SCSI bus,
between the host and last device, typically should have no jumper installed on
Termination Power.
WP - Write Protection
With the Write Protection jumper installed, the drive can be used as a read-only
device. This feature is most useful for frequently accessed archive or reference
files, and prevents accidental overwrites. The factory default for the drive is
with no jumper installed on these pins and the drive can be written to unless
protected by application software
