Motor start delay is 12 times the drive ID number in seconds; i.e. drive ID 0 starts immediately, drive one starts 12 seconds later, etc. Default is no jumper on. 6 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 7. Default is no jumper on. 5 Jumper installed means entire drive is write protected. Default is no jumper on. 4 Jumper installed means parity checking and error reporting by the drive is enabled. Default is no jumper on. 3 Reserved for factory use. No jumper installed. 2 Select terminator power source. In position 1 the drive 1 supplies power to the SCSI bus, pin 26. In position 2 drive supplies power only to its own terminators. Jumper in positions A (between pins 2 and 4) between positions 2 and 1 (nearest PCB edge) means the drive takes power from the SCSI bus, pin 26. Jumpers on both 2 and 1 at same time is allowed.

J6 pin 5 is GND. 5 No jumper. These pins used to connect 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 command through the emitter-collector junction of a transistor switch that controls the LED on/off condition. 6 Reserved position. 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. Make sure that the SCSI bus address jumper(s) are properly set for the bus address assigned to the drive. 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. ********************************************************************** I N S T A L L ********************************************************************** SEAGATE ST11200NC/1950N/1830N/1980N INSTALLATION GUIDE 77738480 REV.D Notes On Installation ===================== Installation Overview --------------------- Installation of the drive can be divided into distinct phases as outlined below. Some of these may not be applicable to your particular installation requirements. Refer to the individual drive installation sections for specific information on your drive model. - Drive configuration: The user must select which of the drive features are appropriate to enable for installation in their system. This is done by installing or removing of the user configuration jumpers found on the drive PCB. "NC" models are probably configured by the host over the 80 pin interface. - Mechanical installation: After setting up the drive configuration the drive must be mechanically in-stalled into the host system and the power and I/ O cables attached. Previously mentioned precautions should be observed - SCSI drives should not be defined in the CMOS: The SCSI Host adapter has 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. Drive installation ------------------ This section describes the physical mounting of the drive in the host cabinet and the logical installation as a system member, which is called drive setup. 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. Installation direction ---------------------- horizontally vertically +-----------------+ +--+ +--+ | | | +-----+ +-----+ | | | | | | | | | +-+-----------------+-+ | | | | | | +---------------------+ | | | | | | | | | | | | | | | | | | +---------------------+ | +-----+ +-----+ | +-+-----------------+-+ +--+ +--+ | | | | +-----------------+ The drive will operate in all axis (6 directions). 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 0.150 inch (3.81 mm), and 0.20 inch (5.08 mm) into bottom holes, measured from the outer surface of the chassis. The minimum thread engagement for all mounting screws is .12 inch (3.0 mm). Tighten the screws evenly to a maximum torque of 8 in-lb. 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 resistor packs 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 (not required on "NC" model drives). - Replace the Host System cover. - Turn on DC power. - Boot the system from the floppy drive or from a previously installed hard-drive if there is one. - Proceed with drive setup of the new hard drive. Grounding --------- Signal ground (PCB) and HDA ground are connected together in the ST11200 drives family 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. NOTES Mounting holes three on each side, 6-32 UNC. Max screw length into side of drive 0.15 in. (3.81 mm). Screw tightening torque 8.0 in-lb max with minimum thread engagement of .12 in (3.00 mm). Mounting holes four on bottom, 6-32 UNC. Max screw length into bottom of drive 0.20 in. (5.08 mm). Screw tightening torque 8.0 in-lb max with minimum thread engagement of .12 in (3.00 mm). Power and interface connections can extend past the "A" dimension by 0.040 in (1.02 mm). Decorative front panel. Connector is centered (side to side) on drive within 0.020 in. (.508 mm). SCSI interface cable connection ------------------------------- Model ST11200 family are SCSI interface drives. On "N/ND" models, system connection is via a 50 pin, SCSI connector. On "NC" models system connection and DC power is via a single 80 pin SCSI connector. Because of its shape, there is only one way the drive can mate with the input connector. Pin 1 is noted in Figure 2. 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 by the routing of cables. ********************************************************************** F E A T U R E S ********************************************************************** SEAGATE ST11200NC/1950/1980/1830N INSTALLATION GUIDE 77738480, REV. D Introduction ------------ Before attempting any installation, please read through all applicable sections of this document, including all warnings and cautions. Warning. This equipment generates, uses, and can radiate radio frequency energy and if not installed in accordance with these instructions, may cause interference to radio communications. Electromagnetic interference (EMI) considerations ------------------------------------------------- The drive(s) described herein, as delivered, are designed for system integration and installation into a suitable enclosure prior to use. As such, the drive(s) described herein are supplied as a subassembly and are not subject to Subpart J of Part 15 of the FCC Rules and Regulations nor the Radio Interference Regula- tions of the Canadian Department of Communications. However, the unit has been tested using proper shield-ing and grounding and found to be compliant with the Class A limits of the FCC Rules and the Regulations of the Canadian Department of Communications. The physical design characteristics of the drive(s) described herein, serve to minimize EMI radiation when installed in an enclosure that provides reason-able shielding. As such, the drive(s) are capable of meeting the Class B limits of the FCC Rules and the Regulations of the Canadian Department of Communi- cations. Note. It is the end users responsibility to assure that the drive(s) described herein meet the appropriate EMI requirements of their system. Shielded I/ O cables may be required if the enclosure does not provide adequate shielding. If I/O cables are external to the enclosure, shielded cables should be used, with the shields grounded to the enclosure and to the host controller. Before you begin ---------------- Verify that the system is switched off and disconnected from main power before any installation is attempted. Protect yourself, the drive, and your valuable programs and data by reading the following cautions and warnings. - Do not unpack drive from its static shielded bag until you are ready to install it in the system. - Always handle the drive by the frame or casting. - Do not touch printed circuit board (PCB) or the I/O connector pins. - Never apply pressure to the PCB or to the drive top cover. - Do not tamper with sealed top cover. Doing so voids your warranty. The drive contains no user servicable components. See Product Repair section for more information. - Visually inspect the shipping container for any obvious damage. - Inspect drive for possible shipping damage. All claims of this type should be filed promptly with the transporter involved. Save original packing materials to be used when reshipping. - Verify all parts listed on shipping bill are received with the equipment. Discrepencies or damage should be reported to the shipping company. Caution. The circuit assemblies and components contained in this equipment can be de-graded or destroyed by Electrostatic Over- stress (EOS) or by Electrostatic Discharge (ESD). Static electrical charges can accumulate quickly on personnel, clothing and synthetic materials. The electrostatic fields due to these charges when brought in close prox-imity to susceptable circuit assemblies and components, can result in degraded reliabil- ity or immediate failure of the affected com-ponent or assembly. - When transporting or shipping a drive or system, please ensure that they are correctly packed in original Seagate approved (or equivalent) container and shipped via an airride carrier experienced in handling computer equipment. To insure optimum reliable equipment operation, it is required that technical support personnel discharge themselves by wear- ing a grounding strap around the wrist and be connected to a grounding terminal while working in the vicinity of, and while handling EOS/ESD susceptible assemblies/parts. If unavailable, ground yourself frequently by touching the metal chassis of the system before handling any components (this helps only if the system is connected to a ground). Avoid static-inducing carpeted areas. Safety instructions ------------------- 1. The disc drive(s) are to be installed in a customer supplied enclosure where the surrounding air does not exceed 50 o C. 2. Four (4) 6-32 UNC-2A screws are required for installation. Maximum screw length into side of drive is 0.15 inches (3.81 mm). Maximum screw length into bottom is 0.20 in. (5.08 mm). 3. The power requirements are shown in Section 1.0 Product Information. 4. The power supply must satisfy the safety requirements for SELV (Safety Extra Low Voltage) circuits. 5. Service is to be provided by trained Seagate service personnel. 6. The incorporation of the disc drives listed in this guide into a customer enclosure must meet the appropriate safety require- ments 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 EN60950: 1988 (IEC 950). Installation Overview --------------------- Installation of the drive can be divided into distinct phases as outlined below. Some of these may not be applicable to your particular installation requirements. Refer to the individual drive installation sections for specific information on your drive model. - Drive configuration: The user must select which of the drive features are appropriate to enable for installation in their system. This is done by installing or removing of the user configuration jumpers found on the drive PCB. "NC" models are probably configured by the host over the 80 pin interface. - 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 drives should not be defined in the CMOS: The SCSI Host adapter has 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: After the drive has been properly configured for the system, it does not need to be low-level formatted, as this has been done by the factory and does not require this step during installation. (The low-level format writes the sector boundaries and track information to the drive). Defect management information is read from the drive by the host system when required in the installation procedure. If an installed drive is low-level formatted, all user data stored on the drive will be lost. Note. Seagate Technology assumes no liability for lost user data. - Partitioning and high level formatting: A drive can be sub-divided into "partitions" which behave as individual drives within the system. See your system documentation. Present day drive installation programs have menus that lead you through these installation procedures. Product repair information/Service requirements ----------------------------------------------- The special facilities required for the manufacture of these drives generally prohibit repair in the field. If problems occur during installation, please contact your supplier for assistance. Do not attempt to dissassemble or repair. Drives should be sent to the repair depot through the purchase source, if possible. Please observe the following cautions. Caution. - Handle drive with care. Do not drop or bump hard. - Never remove the cover of these disc drives. Servicing items in the sealed HDA (heads, media, actua-tor, etc.) require special facilities. The drive contains no user purchasable parts or PCBs. - Opening the sealed HDA voids the drive warranty. - Applying a soldering device to the components on the PCB voids the drive warranty. Initial setup information ------------------------- For the initial setup connect the cables, set the SCSI bus address and remove, install, or leave as is the SCSI I/O line terminator resistor packs. These procedures are described in paragraphs following. Drive setup/SCSI interface drives --------------------------------- The SCSI interface handles both drive geometry and defect management internally or the "no drive installed" option can be selected for systems with SCSI drives. All SCSI interface drives are low-level formatted at the factory. If you wish to low-level format the drive to optimize its 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 partitioning, and FORMAT for high-level formatting. Consult your DOS manual for FORMAT and FDISK command options. Warning. If an installed drive is low-level formatted, all user data stored on the drive is lost. Seagate Technology assumes no liability for lost user data. ********************************************************************** 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.
