+--------------+
J6 Master/Slave
----------------
Selection of the master drive is made by removing the master/slave
jumper. Selection of the slave drive is made by installing the
master/slave jumper.
Pins 1-2 OPEN Only drive in single system
Master in dual drive system
CLOSED Slave in dual drive system
The Master/Slave Jumper is used to configure the drive as a Master
or Slave. If the jumper is removed, the drive is a Master. If the
jumper is installed, the drive is a Slave. For single drive systems,
the jumper should be removed.
Drive is shipped configured for use in a single AT IDE drive system
with all J6 jumpers open except for J6 3-4 (drive active status for
LED), which is optional in single or master drive installations.
J6 Drive Active Status LED
---------------------------
Installing the drive active jumper provides a current source for a
drive active LED to pin 39 of the interface. If the slave present
jumper is installed, the drive active jumper must not be installed.
Pins 3-4 OPTIONAL One drive in single drive system
OPTIONAL Master in dual drive system
OPEN Slave in dual drive system
J6 Slave Present
-----------------
Installing the slave present jumper provides an output on DASP- that
the slave drive is present. If the drive active jumper is installed,
the slave present jumper must not be installed. The slave present
jumper is not needed if both drives in the system are the LXT-200A.
Pins 5-6 OPEN One drive in single drive system
Master in dual drive system
OPTIONAL Slave in dual drive system
The Slave Present jumper is used by the slave to indicate its
presense. It should be installed on the slave drive only. This
jumper is not necessary if both drives are Maxtor LXT drives.
J6 Two Drive System
--------------------
Installing the two drive system jumper on the master drive indicates
that a slave drive is present.
Pins 7-8 OPEN One drive in single drive system
CLOSED Master in dual drive system
OPEN Slave in dual drive system
The Two Drive System jumper is used by the master drive to indicate
the presense of a slave drive. This jumper is not installed by the
slave drive or if only one drive is used.
J6 Manufacturing Jumper
------------------------
Pins 9-10 OPEN Single Drive in System
OPEN Master Drive in System
OPEN Slave in System
The manufacturing jumper is for internal use only. Installing this
jumper may result in damage to the drive and loss of data.

The drive will operate in all axis (6 directions).
Mounting
--------
The drive may be mounted in any position. Certain switching power
supplies may emanate electrical noise, which can degrade the
specified read error rate. For best results, orient the drive so that
the PCB assembly is not adjacent to these noise sources.
Twelve mounting holes, four on the bottom and four on each side, are
provided for mounting the drive into an enclosure. The size and
location of these holes, are identical to industry standards.
Caution: Mounting screw lengths must be chosen so that no more than
0.125 inch of the screw is available to enter the frame mounting
hole. The screw length, if incorrect, will damage the PCB during
installation and void the warranty. The torque applied to the
mounting screws should be between 9 and 12 inch-pounds.
The faceplate is clipped to the front of the HDA and may be removed
in installations that do not require it. Lift up on the faceplate
clips and unplug the LED cable from the PCB.
Air Flow Requirements
---------------------
It is recommended that air flow over the drive PCBA be a minimum of
25 cubic feet per minute.
The maximum temperature of the HDA cover (measured at a point
centered on the cover beneath the PCB), should not be greater than
11* C above the ambient temperature (measured 1/8 inch away from the
PCB). For some installations 200 LFM of air flow may be required to
maintain the temperature specified.
Installation Requirements
-------------------------
The LXT ATA drives must operate in a temperature range between 41*F
and 122*F (5*C and 50*C). The drive should be installed in
applications where temperature extremes outside of this range are
avoided.
Caution: These requirements must be met to ensure proper functioning
of the drive. If they are not met, data loss and/or permanent damage
to the drive may result.
The faceplate is screwed to the front of the HDA in some LXT models,
and clipped to the front in others. The faceplate may be removed in
installations that do not require it.
Shipping
--------
At power down, the heads are automatically positioned over the
dedicated landing zone (nondata) on each disk surface. The automatic
shipping look solenoid is also engaged at this time. Maxtor ships the
drive in single and multipack shipping containers. Users can ship the
drive installed when the nonoperating shock and vibration limits are
not exceeded.
Interface
---------
This chapter describes the interface requirements of the LXT ATA
drives, which are compatible with the AT-BUS. Data is transferred in
a 16-bit wide parallel data path from the host to the drive. Data
transfer is controlled by commands sent from the host. The drive
performs all operations necessary to write data to or read data from
the medium. Data read from the medium is placed in a buffer prior to
being transferred to the host.
This allows two drives to be connected to the host. The primary drive
is designated as the master drive and the secondary drive is
designated as the slave drive.
The maximum cable length connecting the host and the drives is
twenty four inches (0.61 meters).
Interface Connector
-------------------
The interface connector is a 40-pin dual-row header connector. A key
for the mating cable connector is provided by the removal of pin 20.
The corresponding hole on the cable connector should be plugged. The
cable connector should be keyed to prevent the possibility of
installing it upside down.
Recommended part numbers for the mating connector and cables are
shown below. Equivalent parts may be used.
Connector 3M-3417-7000 (Strain Relief 3448-2040, AMP P/N
1-499506-0)
Cable Flat Cable (Stranded AWG 28) 3M-3365-40
Shielded Cable Flat Cable (Stranded AWG 28) 3M-3517-40
J3 Power Connector
-------------------
The four-pin DC power connector J3 is similar to AMP's MATE-N-LOOK
connector, part number 350543-4, however, is surface mounted to the
PCB rather than freehanginng as the AMP part is. Part numbers for the
recommended mating connector and contacts are shown below.

Type of cable 18 AWG
Connector AMP 1-480424-0
Contacts AMP 61173-4 (Loose Piece), AMP 350078-4 (Strip)
Buffer Access
-------------
The LXT products use zone density recording. This recording technique
varies the number of bytes per track (Mbytes/sec) which must be read
or written.
The LXT ATA drives are manufactured with either 32K or 64K of buffer
RAM. To confirm the buffer size of your drive, execute the IDENTIFY
command.
Translate Mode
--------------
The drive always operates in the translate mode because it uses
zoned recording techniques. The drive firmware translates logical
sector requests from the host into corresponding physical sector
requests.
Because the host communicates with the drive using physical drive
parameters, a mapping address translation is needed to fully utilize
the capacity of the drive. This also makes selecting a drive type
from the BIOS tables easier. The drive type selected should have a
capacity equal to or less than the formatted capacity of the drive.
Note: To achieve full memory capability of the LXT-535A drive, an
advanced BIOS must be used. The standard BIOS allows for only 1,024
cylinders (1,024 x 16 x 63 x 512 = 528 MB).
Air Filtration System
---------------------
The disks and read/write heads are assembled in a Class 100
environment and then sealed within the head disk assembly (HDA).
The HDA contains an absolute filter, mounted inside the casting, to
provide constant internal air filtration.
J4 Service Connector LXT-200A
-----------------------------
Connector J4 is a service connector providing the RS-232 interface
and the ability to carry the LED signal beyond the drive. The RS-232
is used to load new firmware updates to the drive. The service
connector is a ten-pin part. The mating connector is a Berg 6976410
part.
When an LED is connected to pin nine (+) and pin ten (-), that LED
functions in the same manner as the LED which is mounted on the
drive's faceplate. This is typically used in cases where the drive is
mounted in a position where the drive's LED is not visible and the
faceplate is removed.
Pins two through four are the RS-232 lines used to down load firmware
updates to the microprocessor which are then stored on the disk.
Pins three (transmit data) and four (receive data) are the main
communication lines. Pin two is used to debug the processor and for
a non-maskable interrupt. Pins five and six are signal ground lines.
Ground Connector
----------------
Logic ground and chassis ground are tied together and an insert
description lug is provided for connection to system ground.

Defect Management
-----------------
A complicated flaw scan process to generate the defect list is done
at the factory for every drive. As shipped from the factory, the
drive is pre-formatted with all defects reassigned to spare sectors.
When reassigning defect sectors, the track is laid out again so that
the defect area is skipped. One-to-one interleave and skewing factors
are rearranged to maintain the streaming performance. The drive is
assumed to be error-free after formatting.
Synchronized Spindle
--------------------
The LXT ATA drives are able to synchronize their spindles together
for use in disk drive arrays.
This is accomplished by having all drives in the array synchronized
to a common pulsed signal. This sync signal can be provided by either
an external source or one of the drives. The sync signal can be
transceived on either the service connector (J4 pin 8) or the ATA bus
(J1 pin 28). However, at the time this manual was printed,
synchronized spindle was not available on J1 pin 28.
If the sync pulses are to be generated by an external source, the
sync pulses should be a negative going TTL pulse with a minimum width
of 2 sec and a frequency of 60 Hz +/- 0.5%.
Power-Up Sequence
-----------------
DC power (+5V and +12V) may be supplied in any order. Both power
supplies must be present and within the tolerances of the power
sensing circuit, before the spin motor will spin up. When the spindle
reaches full speed, the actuator lock automatically disengages. The
drive spins up and becomes ready within 8 seconds. The drive
executes its recalibration sequence whenever power is applied.
