 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 Sync Spindle
 -------------------
   Pinset 7 have no effect if Sync Spindle Mode is disabled.

   Upper pin is sync output in Master mode, or sync inout in Slave
   mode.

   Do NOT short this pinset. The purpose of the lower pin is to
   provide a ground for external cabling.

 J6 3-4  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

J6 1-2 Reserved, must be open.

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

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.
