A Jumper setting ============== Each disk 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. J2 Motor Start/Write Protect/Terminator Power ---------------------------------------------- +-1--2--3--4--5--6--7--8-+ | o X o o o o o 1 | | o X o o o o xxxx | +----+-------------------+ \ Position A Position 2 1 for Factory use only. 2 Jumper installed in position 2 enables the Delayed Motor Start option (if jumper in position 3 is off). Motor start delays is 12 times the drive ID number in seconds; i.e. drive ID 0 starts immediately. drive one starts 12 seconds later, etc. Not factory installed. 3 Jumper installed enables Motor Start option. The drive waits for the Start unit command from the host before starting the spindle motor. If no jumper is installed, drive operation de- pends on wether or not there is a jumper in position 2. Not factory installed. If jumpers 2 and 3 are both off, drive spins up with no delay when power is applied. 4 Jumper installed means entire drive is write protected. Not factory installed. 5 Jumper installed means parity checking by the drive is enabled. Not factory installed. 6 Reserved for later use. 7 Select terminator power source. In position 8 the drive 8 supplies power to the SCSI bus, pin 26. In position 7 drive supplies power only to its own terminators. (Factory setting) Jumper horizontally between positions 7 and 8 (position A) means the drive takes power from the SCSI bus, pin 26. Jumpers installed on both 7 and 8 at same time is allowed. Default is jumper on position 7.

The factory installs no ID jumpers on J5 or J6 (drive ID 0). 4 Used as a cable connection for the Ref Index/+L signal for sync spindle feature. 5 Used if needed for a connection to a remote LED indicator. Pin 10 (lower row), connects in the drive to the +5 V supply. Pin 9 (closest to drive HDA), connects in the drive to ground. 6 Reserved. On SCSI I/O 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. ********************************************************************** I N S T A L L ********************************************************************** SEAGATE ST3600 FAMILY INSTALLATION GUIDE 77738481, REV. A Installation ============ Installation direction ---------------------- horizontally vertically +-----------------+ +--+ +--+ | | | +-----+ +-----+ | | | | | | | | | +-+-----------------+-+ | | | | | | +---------------------+ | | | | | | | | | | | | | | | | | | +---------------------+ | +-----+ +-----+ | +-+-----------------+-+ +--+ +--+ | | | | +-----------------+ The drive may be mounted in any orientation. 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 surfce of the chassis. Tighten the screws down evenly to approximately 8 inch-Ibl. Do not over tigthen 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. The disc drive(s) are to be installed in a customer supplied enclosure where the surrounding air does not exceed 50* C. Grounding --------- Signal ground (PCB) and HDA ground are connected together in the ST3600 drive 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. SCSI interface cable connection ------------------------------- Models ST3600N/ND 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. Do not block system cooling air flow in routing of cables. AT (IDE) interface cable connection ----------------------------------- Model ST3600A Family drives AT (IDE) interface drive. System connection is via a 40 pin AT (IDE) connector. Some cables have a contrasting color strip on one edge to indicate pin 1. Use a strain relief device at the cable. Do not block system cooling air with the routing of cables. Connect the AT (IDE) I/O connector cable end to drive 0 (master) and if there is a drive 1 (slave) connect it to the connector in the middle of the cable. Order of locating the drives in the daisychain is not as important as getting proper drive ID set up for the drives intended for drive 0 and drive 1. DC Power connection ------------------- The drive receives DC power through a 4 pin connector mounted on the PCB next to the SCSI or AT (IDE) I/O connector. Pin 1 +12 V 2 +12 V Return 3 + 5 V Return 4 + 5 V SCSI Resistor terminator packs ------------------------------ If you are installing a single drive, the resistor terminator packs must remain installed. If you are installing multiple hard disc drives, remove the resistor termination packs from all the drives but the one connected to the end of the SCSI I/O cable. When reinstalling a resisor pack, note that pin 1 end on the pack is denoted by a dot, a number one or a notch. Usually, a square pad on the disc drive printed wiring assembly indicates pin 1 at the socket. Model numbers that end in "ND" have differential I/O circuits and these drives have no provisions for terminators that plug into the drive PCB. The system manufacturer must provide some external means of I/O line termination. The AT (IDE) interface drives have permanent internal I/O line termination and do not have removable terminators. ********************************************************************** F E A T U R E S ********************************************************************** SEAGATE ST3600 FAMILY INSTALLATION GUIDE 77738481, REV. A Electromagnetic interference (EMI) considerations ------------------------------------------------- The drive(s) described herein, as delivered, are designed for system integration and installing into a suitable enclosure prior to use. As such, the drive(s) described herein are supplied as a sub-assembly and are not subject to Subpart J of Part 15 of the FCC Rules and Regulations nor the radio Interference Regulations of the Canadian Department of Communications. However, the unit has been tested using proper shielding and ground- ing and found to be compliant with the Class A limits of the FCC Rules and the Regulations of the Canadian Department of Communications. Safety instructions ------------------- The power supply must satisfy the safety requirements for SELV (Safety Extra Low Voltage) circuits. The incorporation of the disc drives listed in this guide into a customer enclosure must meet the appropriate safety requirements of the country in which it is used (e.g. UL 1950, CAN/CSA-C22.2 No. 950- M89, DIN VDE 0805/05.90 and EN 60950:1988 (IEC 950). Low Level formatting -------------------- All ST3600 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. Partitioning and high level formatting -------------------------------------- A drive can be sub-divided into "partitions" which behave as individual drives within the system. 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. Write precompensation and reduced write current ----------------------------------------------- Not required on Seagate SCSI or AT (IDE) interface drives covered by this manual. SCSI interface drives --------------------- The SCSI interface handles both drive geometry and defect management internally. In AT systems a drive type of zero, or 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 performance 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 partiioning, and FORMAT for high-level formatting. AT (IDE) interface drives ------------------------- Seagate AT interface drives mimic (translate) other drive geometries. If none of the drive types offered by the CMOS supports the number of heads, cylinders and sectors shown by the table, and your system does not support a "user-defined" drive type, then select a drive type in your system CMOS with a capacity which is less than or equal to the capacity given in the "MBytes" section of the table. Model MBytes (F) Cylinders R/W Heads Sectors/Track ST3600A 528 1024 16 63 ST3500A 426 895 15 62 When specifying drive geometry to the systems CMOS different values may be used for the Cylinders, Read/Write Heads and Sectors/Track than those given below. However, the final drive capacity shown by the CMOS cannot exceed the capacity shown in the MBytes column of the table. If your BIOS offers a "custom drive" or a "user-defined" drive type, use one of the configurations listed in the previous table. The CMOS calculation of drive capacity is based on a variation of the number of bits in a megabyte, for purposes related to hexadecimal addressing. When the drive geometry has been entered into the "user defined" or "custom" drive type. This number should correspond with the capacity listed in the MBytes column of the table. Note that the drive will provide the user with full capacity as specified in the MBytes (F) column of the table. The drive capacity can be verified by using the CHKDSK utility provided with DOS after the high-level formatting has been completed.
