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.
7 CLOSED, 8 CLOSED Not Allowed

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.
