 Pins 1 Write Protect
 --------------------
   OPEN   Drive looks at Mode Page header and responds accordingly;
          Default = NOT write protected
   CLOSED Drive is forced into the Write Protect Mode.

 Pins 2 Unit Attention
 ---------------------
   OPEN   Enable Unit Attention
   CLOSED Inhibit Unit Attention

 Pins 3 SDTR
 -----------
   OPEN   Inhibit drive initiation of SDTR message
   CLOSED Enable drive initiation of SDTR message at Power-On and
          Reset.

 Pins 4 Parity
 -------------
   OPEN   Inhibit Parity
   CLOSED Enable parity checking

 Pins 5 Auto Spin-Up
 -------------------
   OPEN   Drive will not spin up until Initiator sends Start Unit
          Command
   CLOSED Drive will spin up automatically at Power-On

 Pins 7, 8  SCSI pin 29
 ----------------------
   Note: Pinsets 7 and 8 have no effect if Sync Spindle Mode is
   disabled.

   7 and 8 OPEN       Not Allowed

   7 OPEN, 8 CLOSED   Connects Sync Spindle line to SCSI pin 29. When
                      Pinset 8 is CLOSED, pinset 7 MUST be OPEN.

   7 CLOSED, 8 OPEN   Connects SCSI pin 29 to ground. Upper pin of
                      pinset 8 is sync output in Master mode, or sync
                      input in Slave mode. When pinset 7 is shorted,
                      pinset 8 must be open.

 J4 1-2  SCSI-1/SCSI-2
 ---------------------
   OPEN   Drive looks at Mode Page 09, byte 8, bit 4 and responds
          accordingly; default = SCSI-2
   CLOSED Drive is forced to respond as a SCSI-1 device

J4 3-4 and J5 3-4 Terminator Power Source Options
--------------------------------------------------
The single-ended drive is shipped with active terminator circuits
installed. When installing multiple drives on the SCSI channel, the
terminators must be disabled on all but the last drive in the chain.
When the Terminator Enable jumper is installed, the terminators are
connected to the SCSI connector; when removed, the terminators are
disconnected from the SCSI connector.

Active terminators should be powered by Terminator voltage (TermPwr)
whenever the drive is connected to an active SCSI bus to avoid
exceeding the bus high-state input current specification. The
Terminator Power jumper determines the TermPwr source as listed
below.

Note: Terminator Enable jumper must be installed to connect the
active terminators to the SCSI connector.

J5 1-2 Reserved, must be open.

 J5 3-4 Terminator Enable
    OPEN   On-board active terminators disabled. Terminators not
           connected to SCSI Connector.
    CLOSED On-board active terminators enabled and connected to SCSI
           bus. TermPwr source determined by placement of Terminator
           Power pinset jumper.

 J4 3-4 Terminator Power
    OPEN   TermPwr for on-board terminators provided by the drive
           only. Drive TermPwr is not connected to SCSI connector pin
           26.
    CLOSED TermPwr for on-board terminators provided by the drive, and
           drive, and drive TermPwr is connected to SCSI connector pin
           26.

Mounting Clearances
-------------------
Insure that system mounting structures contact only the drive mount-
ing frames and clear any point on the drive HDA by at least 0.06 in.
(1.5 mm).

Adjust mounting hardware and spacer dimensions to maintain a minimum
clearance of 0.06 in. (1.5 mm) between any system structure and the
top ans all four sides of the disk drive.

Adjust mounting hardware and spacer dimensions to maintain a minimum
clearance of 0.04 in. (1.0 mm) between any system structure and any
PCA component.

Use 6-32 UNC screws with flat washers under the heads and torque them
to 15 inch-pounds.

When mounted, the screws should not protrude more than 0.12 in. (3
mm) beyond the inside of the disk drive mounting frames.

Recommended Mounting Connectors
-------------------------------
SCSI Connector (narrow:
single-ended, differential) 3M 3425-6600

SCSI Connector (wide:
differential) AMP 786090-7

DC Power AMP 1-480424-0

Synchronized Spindle Connector AMP Housing 4-87456-9 *1

LED Connector AMP 102107-3 (for AWG 22-26 wire)

Shorting Jumpers
----------------
2x1 shorting jumper: Dupont 86730-001 (HP p/n 1258-0209)
2x2 connector housing: Dupont 69307-004 *2
2x3 connector housing: Dupont 69307-006 *2
2x5 connector housing: Dupont 69307-010 *2

 Notes:
 *1    Contact insert required (For AWG 20-24 wire, use AMP 1-87309-4)
 *2    Contact inserts required (For AWG 26-30 wire, use Dupont
       77138-101; for AWG 32-36 wire, ue Dupont 77139-101)

Operating Temperature Guidelines
--------------------------------
The operating ambient air temperature specification is 5*C to 50*C
(41*F to 122*F).

Adjust the ambient air temperature to prevent the temperature at each
location from exceeding the stated limit.

The recommended air flow to maintain the component temperatures is 3
to 5 CFM (cubic feet per minute) with most of the air flowing across
the printed circuit board.

Wide differential
-----------------
The recommended air flow to maintain the component temperatures is 4
to 6 CFM (cubic feet per minute) with most of the air flowing across
the printed circuit board.

Adjust the air flow to prevent the temperature at each location from
exceeding the stated limit.
