Pins 2 SCSI-1/SCSI-2 --------------------- When the SCSI-1/2 pin is active, and if the SCSI-1 mode is required, the jumper must be placed sideways. If the SCSI-1/2 pin is active 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 Pins 3 SDTR/UA -------------- Mode Select page 23H determines whether the SDTR/UA (unit Attention) pin is active or not. When active, Mode Select page 23H determines whether the pin functions as SDTR or Unit Attention. If the SDTR function is active: OPEN Inhibit drive initiation of SDTR message CLOSED Enable drive initiation of SDTR message at Power-On and Reset. If the Unit Attention function is active: OPEN Enable Unit Attention CLOSED Inhibit Unit Attention Pins 4 LED Driver ----------------- An LED requiring 10 ma may be connected across pinset 4. 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 Pins 10,11,12 SCSI Address -------------------------- +----------+-----------------------+ | SCSI | Pins | | Adress | 10 | 11 | 12 | +----------+-------+-------+-------+ | 0 | OPEN | OPEN | OPEN | +----------+-------+-------+-------+ | 1 | OPEN | OPEN | CLOSED| +----------+-------+-------+-------+ | 2 | OPEN | CLOSED| OPEN | +----------+-------+-------+-------+ | 3 | OPEN | CLOSED| CLOSED| +----------+-------+-------+-------+ | 4 | CLOSED| OPEN | OPEN | +----------+-------+-------+-------+ | 5 | CLOSED| OPEN | CLOSED| +----------+-------+-------+-------+ | 6 | CLOSED| CLOSED| OPEN | +----------+-------+-------+-------+ | 7 | CLOSED| CLOSED| CLOSED| +----------+-------+-------+-------+ J4 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 terminator IC is active on the drive's SCSI bus connector; when removed, the terminator, are disconnect from the SCSI connector. Active terminators should be powered by Terminator voltage (TermPwr) whwnever 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. 1 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. 3 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. ********************************************************************** I N S T A L L ********************************************************************** HEWLETT HP C3324/C3724/C3325/C3725 SINGLE-ENDED PRODUCT DESCRIPTION Notes on installation ===================== Installation direction ---------------------- horizontally vertically +-----------------+ +--+ +--+ | | | +-----+ +-----+ | | | | | | | | | +-+-----------------+-+ | | | | | | +---------------------+ | | | | | | | | | | | | | | | | | | +---------------------+ | +-----+ +-----+ | +-+-----------------+-+ +--+ +--+ | | | | +-----------------+ Mounting Clearances ------------------- Maintain a minimum clearance of 0.040 in. (1.0 mm) between any system structure and the top, bottom (PCA), sides (for bottom mounting) and ends of the disk drive. For side mounting, minimize the contact be- tween the drive and any system structure. 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 (1.7 Newton-meters). When mounted, the screws should not protrude more than 0.25 in. (6.35 mm) into the disk driveside or bottom mounting holes.
