Jumpers
MAXTOR LXT 100S FAMILY PRODUCT SPECIFICATION 1018327 REV. A
Jumper Setting
==============
x = Jumpers set at factory
J9, pins one through five, and J10 pins one through four, determine
the disk drive operation modes. The jumpers are used primarily for
isolation testing at the factory or authorized repair center.
J2-1/3/4 CLOSED
J2-2 OPEN
J9 all OPEN
J10 all CLOSED
J11 CLOSED
J2 Parity Option
----------------
x J2-1 CLOSED Enables odd parity detection in the disk drive.
OPEN Disables odd parity detection in the disk drive.
Odd parity is always generated by the disk drive and provided to the
SCSI bus.
J2 SCSI Identification Selection
--------------------------------
+----------+-----------------------+----------+ | SCSI ID | Jumpers | | | | J2-4 | J2-3 | J2-2 | Priority | +----------+-------+-------+-------+----------+ | 0 | OPEN | OPEN | OPEN | Lowest | | 1 | OPEN | OPEN | CLOSED| . | | 2 | OPEN | CLOSED| OPEN | . | | 3 | OPEN | CLOSED| CLOSED| . | | 4 | CLOSED| OPEN | OPEN | . | | 5 | CLOSED| OPEN | CLOSED| . | | x 6 | CLOSED| CLOSED| OPEN | . | | 7 | CLOSED| CLOSED| CLOSED| Highest | +----------+-------+-------+-------+----------+
SCSI identification (ID) jumpers (J2, pin four, pin three, and pin
two) are provided to configure each disk drive with a SCSI device ID
for use in multiple SCSI device configurations.
An ID of seven is the highest priority in a multidevice configura-
tion, and is usually used for the initiator.
The disk drive is shipped with an ID of six. This ensures that
sufficient jumpers are available for any address except seven which
is usually reserved for the host system.

J9 Remote Start/Stop
--------------------
x J9-6 OPEN The disk drive starts immediately when power is
applied.
CLOSED Wait for START/STOP UNIT Command
The remote start/stop jumper, J9, pin six, when installed, allows the
disk drive to be started or stopped by using the SCSI START/STOP UNIT
command.
J10 Mode
--------
Pins 1, 2, 3, 4, 5, 6 CLOSED Mode NORMAL
J11 Termination Power

Pins 1, 2 CLOSED Mode TERMINATION POWER

MAXTOR LXT 100S FAMILY PRODUCT SPECIFICATION 1018327, REV. A
Interface Termination
---------------------
SCSI devices require proper interface termination. The first device
and the last device on the daisy chain SCSI bus must be terminated.
Remove the terminators from any devices in between. For instance, if
the disk drive is in the middle of the string, remove its
terminators.
As shipped, interface signal lines are terminated with three
removable 220/330-ohm resistor network packs.
The devices driving the disk drive inputs should be open collector
devices capable of sinking at least 48 milliamps at a voltage of
less than 0.5 volts DC (7438-type or equivalent).
Devices receiving the disk drive outputs should be of SCHMITT
trigger type to improve noise immunity (74LS14, 74LS240, or
equivalent). The initiator should not load the bus with more than
one standard low power Schotky transistor-transistor logic (LSTTL)
input per line, and should terminate all signals with 220/330-ohm
terminators.
Features
MAXTOR LXT 100S FAMILY PRODUCT SPECIFICATION 1018327, REV. A
Self Configuration
------------------
When the disk drive powers up, or when it is reset, it configures
itself using the parameters and information saved on the disk drive
from the previous format operation. This includes the disk drive's
exact model number returned in the INQUIRY command and parameters
in the MODE SELECT pages of parameters.
A UNIT ATTENTION condition is created for each initiator whenever the
disk drive has been reset (by a BUS DEVICE RESET message or a RESET
condition), or when the MODE SELECT parameters have been changed by
other initiators. The UNIT ATTENTION condition persists for each
initiator until that initiator issues any command (other than
INQUIRY) which clears the UNIT ATTENTION condition.
If an INQUIRY command is received from an initiator with a pending
UNIT ATTENTION condition (before the disk drive reports the CHECK
CONDITION status), the disk drive reports any pending sense data and
preserves the UNIT ATTENTION condition.
If a REQUEST SENSE command is received from an initiator with a
pending UNIT ATTENTION condition (before the disk reports the CHECK
CONDITION status), the disk drive reports any pending sense data and
preserves the UNIT ATTENTION condition in the sense data. The CHECK
CONDITION, however, is cleared and a GOOD status is returned on any
subsequent command. Any subsequent command then clears the UNIT
ATTENTION condition from the sense data.
