Default is jumper installed. Off Terminator circuits are disabled. NOTE ND models do not have terminators on the drive PCB, so these jumpers are not applicable. TP TP Off Off No terminator power is connected to drive terminators or SCSI bus I/O pin 26. On Off Drive supplies its own terminator power only. Jumper on this position is factory default for "N" models only. Off On Drive supplies power to I/O pin 26 of SCSI bus; none to internal terminators. When drives have differential I/O circuits, a jumper on the right TP position may be needed to power external termina-tors (see system documentation). The "ND" model drives have differential I/O circuits which have no terminator circuits on the drive. On On Drive supplies terminator power to itself (internal connection) and to I/O pin 26 of SCSI bus. This is a legal jumper setting. TP Position A ("N" family models only) -------------------------------------- On This horizontally positioned jumper across the two TP positions nearest PCB edge, connects terminator power from SCSI bus I/O pin 26 to the drive's internal terminators. Off See above explanations for TP jumpers. DS ME Off Off Spindle starts immediately after power up - Default setting. Off On Drive spindle does not start until Start Unit command received from host. On Off Spindle Startup is delayed by SCSI ID times 12 seconds after power is applied, i.e., drive 0 spindle starts immediately when DC power connected, drive 1 starts after 12 second delay, drive 2 starts after 24 second delay, etc. On On Drive spindle starts when Start Unit command received from host. Delayed start feature is overridden and does not apply when ME jumper is installed. WP On Entire drive is write protected. Off Drive is not write protected. Default is no WP jumper installed. PE On Parity checking and parity error reporting by the drive is enabled. Off Drive does not report result of parity checking to host. Default is a PE jumper installed. SS Off/On Reserved. Default is no jumper installed.

Typically the primary boot device is set to ID 0, and the subsequent SCSI drives are jumpered in ascending order. Bus addresses 0 through 6 should be used (the host adapter usually uses address 7). If the drive LED shows no on/off activity when the host is trying to communicate with it, an incorrect bus address selection at the drive should be suspected. +----------+-----------------------+ | SCSI ID | Jumpers | | | ID4 | ID2 | ID1 | +----------+-------+-------+-------+ | 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| +----------+-------+-------+-------+ FRONT VIEW J6 TOP (HDA) +-----1+ ---PWA-----------------------------+::::::+----- +------+ ID4 -+||||+- RESERVED ID2 --+||+-- Remote LED (pin-3 +5V) ID1 ---++--- Spindle Sync (pin-6 REF SIG+) J6 SCSI ID ----------- +----------+-----------------------+ | SCSI ID | Jumpers | | | ID4 | ID2 | ID1 | +----------+-------+-------+-------+ | 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| +----------+-------+-------+-------+ If these ID jumpers are used, the ID jumpers shown in left side view ARE NOT USED. Bus termination --------------- Model "N" drives have an active terminator IC that is permanently installed, but can be enabled or disabled by a jumper plug. If you are installing a single drive, the terminator IC must remain enabled. If you are installing multiple hard disc drives, disable the termination IC on all the drives but the one connected to the end of the SCSI I/O cable. Model numbers that end in "ND" have differential I/O circuits. These drives have no provisions for terminators on the drive PCB. The system manufacturer must provide some external means of I/O line termination. The "ND" model drives can provide power for external terminators if the TP jumper is installed on the last position on the right end of J2. Optional parity bit enable -------------------------- Some systems require parity bit checking. Consult the system documentation for the specific requirements. Jumper-installed enables parity reporting by the SCSI bus. Write precompensation and reduced write current ----------------------------------------------- Not required on Seagate SCSI Interface drives covered by this manual. Drive configuration ------------------- Each disc drive has one or more option select header connectors on the back, side or front where jumper plugs are installed to select the way that the drive is to be configured or to select its ID on the I/O bus. Hawk 2LP family N/ND models (50 pin SCSI I/O) --------------------------------------------- On Model N/ND drives either J6 (on the front of the drive) or J5 (on the side behind the DC Power connector) may be used to set the drive ID. To avoid possible incorrect ID setting, do not use both J5 and J6 for ID selection. LED --- These pins used to connect a cable for a remote LED indicator. Pin 3 (top, nearest HDA), the anode connection, connects in the drive to the +5V supply through a pull-up resistor. Pin 4 (bottom), the cathode connection connects in the drive to signal common through the emitter-collector junction of a transistor switch that controls the LED on/off condition. ********************************************************************** I N S T A L L ********************************************************************** SEAGATE ST32430/31230N/ND31221N INSTALLATION GUIDE 77767499 REV.A,95 Notes On Installation ===================== Disc drive mounting ------------------- Do not touch the connector pins or any PCB components without observing static-discharge precautions. Always handle the drive by the frame only. The drive may be mounted in any orientation. horizontally vertically +-----------------+ +--+ +--+ | | | +-----+ +-----+ | | | | | | | | | +-+-----------------+-+ | | | | | | +---------------------+ | | | | | | | | | | | | | | | | | | +---------------------+ | +-----+ +-----+ | +-+-----------------+-+ +--+ +--+ | | | | +-----------------+ The drive will operate in all axis (6 directions). Mount to host system chassis using four 6-32 UNC screws. Three mounting holes are in each side and four in the bottom of the drive. The maximum length that the screws should extend into the side chassis mounting holes is 0.15 inch (3.81 mm), and 0.20 inch (5.1 mm) into bottom holes, measured from the outer surface of the chassis. The minimum thread engagement for all mounting screws is 0.12 inch (3.0 mm). Tighten the screws evenly to a maximum torque of 6 in-lb (.675 NM). Do not over tighten or force when screw does not seem to screw in easily (threads not correctly engaged). Verify that all connections between the drive and the host system are correctly installed. Most cables have a contrasting color stripe indicating pin 1. Verify option select and drive ID select jumpers and installation of terminator enable jumper where applicable. Do not power up the host system until the drive is mounted and the system cover is replaced. Connect DC power connector to the drive. Replace the Host System cover. Turn on DC power. Mechanical installation ----------------------- After setting up the drive configuration the drive must be mechanically installed into the host system and the power and I/O cables attached. Previously mentioned precautions should be observed. SCSI interface cable connection ------------------------------- Models Hawk 2LP family are SCSI interface drives. System connection is via a 50 pin SCSI connector. Some cables have a contrasting color stripe on one edge to indicate pin 1. Strain relief is recommended at the cable in drives using cables. Do not block system cooling air flow in routing of cables. Read/Write head auto-park ------------------------- Seagate disc drives described herein mentioned in this drive park the heads automatically at power off. This feature requires no operator intervention. Grounding --------- Signal ground (PCB) and HDA ground are connected together in the Hawk 2LP family drives and cannot be separated by the user. The equipment in which the drive is mounted is connected directly to the HDA and PCB with no electrically isolating shock mounts. If it is desired for the system chassis to not be connected to the HDA/PCB ground, the systems integrator or user must provide a nonconductive (electrically isolating) method of mounting the drive in the host equipment. ********************************************************************** F E A T U R E S ********************************************************************** SEAGATE ST32430/31230N/ND 31231N INSTALLATION GUIDE 77767499, REV.A General ------- Safety Instructions ------------------- The disk drives are to be installed in a cuatomer supplied enclosure where the surrounding air does not exceed 50*C. CMOS configuration ------------------ SCSI drives should not be defined in the CMOS. The SCSI host adapter uses its own BIOS to handle the Input/Output procedures. The CMOS setting for SCSI drive is either drive type zero, or the no drive installed option. Low-Level formatting -------------------- All Hawk 2LP family drive models are low-level formatted at the factory and do not require this step during installation. If an installed drive is low-level formatted, all user data will be lost. Note: Seagate Technology assumes no liability for lost user data. Partitioning and high level formatting -------------------------------------- A drive can be subdivided into "partitions" which behave as individual drives within the system. Consult the system documentation for instructions on partitioning and high level formatting. Information is also available in bookstores and libraries. SCSI interface drives --------------------- The SCSI interface handles both drive geometry and defect management internally. The "no drive installed" option is selected for systems with SCSI drives. All SCSI interface drives are low-level formatted at the factory. You may wish to low-level format the drive to optimize its perform- ance for your system. Consult the controller documentation for information on low-level formatting. Partitioning and high-level formatting can be done through DOS by way of the FDISK utility for partitioning, and FORMAT for high-level formatting. Consult your DOS manual for FORMAT and FDISK command options. ********************************************************************** G E N E R A L ********************************************************************** SEAGATE SUPPORT SERVICES Seagate Technology ------------------ Technical Support Services If you need assistance installing your drive, consult your dealer.
