 In multidrive configurations, it is necessary to configure each drive
 with a unique address. A maximum of seven drives is permitted per
 host controller. The address for the drive is determined by install-
 ing the jumper plug in the appropriate jumper location.
 Removing the jumper entirely is equivalent to "no select".

Read Gate Delay Jumpers
-----------------------
Jumpers JP7 and JP8 have been provided to allow a specified delay to
be set on the read gate received by the controller. As shipped by the
factory, these jumpers are configured for zero delay. During applica-
tion testing, Maxtor has found that many controllers require some
delay. Maxtor recommends trying 533ns. There is no risk of data
corruption, however RECORD NOT FOUND errors may occur in testing
various settings.

 * The information in this table assumes that JP6 is out; drive is in
 the remote spin mode. If JP6 is in, ignore this column. This table
 applies only to drives with firmwate revision level M2.2 and higher.

JP14 Write Protect Selection Jumper
-----------------------------------
Jumper JP14 is the write protect jumper. When the jumper is present
(installed), the drive is write protected and can only be read; no
writing can take place. As shipped from the factory, jumper JP14 is
removed.

JP6 Sequential Spindle Motor Spinup Jumper
------------------------------------------
The spindle motor spinup jumper allows a string of drives to be
started sequentially be the controller. When the jumper is present
(installed), the drive automatically pins up as soon as power is
applied. If JP6 is removed, the drive is started by issuing the
appropriate command from the controller. As shipped from the factory,
jumper JP6 is installed.

JP16-JP29 Hard Sector Configuration Jumper
-------------------------------------------
JP31 selects the mode of operation. When JP31 is installed, it
configures the drive as a soft sector drive; when removed, it
configures the drive as a hard sector drive.

Jumper JP16 through JP29 allow the user to configure the drive's hard
sector size. The sector size can range from a minimum of 123 to a
maximum of 31,410 unformatted bytes per sector, with 1 byte
granularity.

The hard sector configuration jumpers are encoded in a binary
fashion, with JP16 being the least significant byte and JP29 being
the most significant byte. An installed jumper selects the binary
value.

Jumper JP30, if installed, enables setting the hard sector size over
the ESDI. The drive must be in hard sector mode (i.e. JP31 removed).

   +-----------------+

The drive will operate in all axis (6 directions).

Mounting
--------
The XT-8000E may be mounted in any orientation. In any final mounting
configuration, ensure that the operation of the three shock mounts
which, isolate the base casting from the frame is not restricted.
Certain switching power suppplies 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.

Mounting Holes
--------------
Eight mounting holes, four on the bottom and two on each side, are
provided for mounting the drive into an enclosure. The size and
location of these holes are identical to industry standard floppy
drives.

Caution: The casting is very close to the frame mounting holes in
some locations. Mounting screws lengths must be chosen such that no
more than 0.125 inch of the screw is available to enter the frame
mounting hole. The torque applied to the mounting screws must be
between 9 and 12 inch pounds.

Installation Requirements
-------------------------
The XT-8000E must operate in a temperature range between 50*F and
122*F (10*C and 50*C). The drive should be installed in applications
where temperature extremes outside of this range are avoided.

To maintain proper operating temperature, the XT-8000E must be
mounted in such a way as to ensure adequate airflow.

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 will result.

J1/P1 Connector
---------------
Connection to J1 is via a 34-pin OCB edge connector. The pins are
numbered 1 through 34 with the even pins located on the component
side of the PCB. Oin 2 is located on the end of the PCB connector
closet to the DC power connector J3/P3. A key slot is provided
between pins 4 and 6. The recommended mating connector for P1 is AMP
ribbon connector, P/N 88373-3.

J2/P2 Connector
---------------
Connection to J2 is via a 20-pin PCB edge connector. The pins are
numbered 1 through 20 with the even pins located on the component
side of the PCB. The recommended mating connector for P2 is AMP
ribbon connector, P/N 88373-6. A key slot is provided between pins 4
and 6.

J3/P3 Connector
---------------
The DC power connector, (J3), is a 4-pin AMP MATE-N-LOCK connector,
P/N 350543-1 mounted on the solder side of the PCB. The recommended
mating connector (P3) is AMP P/N 1-480424-0 using AMP pins P/N
350078-4 (strip) or P/N 61173-4 (loose piece).

J4/P4 Frame Ground Connector
----------------------------
The frame fround connector is a Faston type connector, AMP P/N
61761-2. The recommended mating connector is AMP P/N 62187-1. If wire
is used, the hole in J4 will accommodate a maximum wire size of 18
AWG. Normally, this connector is not used.

J6/P6 Auxiliary Connector
-------------------------
The auxiliary connector is a Berg 68451-121, 10 pin connector. The
mating connector is a 3M 3473-6010 connector.

Removable Faceplate
-------------------
The faceplate may be removed in installations where it is not
required. Remove the two e-clips and unplug the LED cable from the
PCB.
