D WC/DC Setting the SCSI ID jumpers --------------------------------- The SCSI ID for WC and DC drives is normally set over the SCSI bus by the host system using connector contacts 39 (ID0), 40 (ID2), 79 (ID1), and 80 (ID3). Systems designers may, optionally, install a remote operator panel connection to set the SCSI ID.

You must provide single-ended external active termination (ANSI SCSI-2 Alternative 2) to these drives when termination is required. Synchronizing spindles Spindle synchronization for WC and DC drives is normally handled on the SCSI bus by the host system using connector contact 37 for the spindle synce reference signal. System designers may, optionally, install a spindle sync cable using pin 6 on the J4 connector to provide +SSREF. DC drives --------- SCSI ID jumpers Each device on the SCSI chain must have a unique SCSI ID. The host system's SCSI controller usually uses the highest- numbered ID available; therefore the lower-numbered SCSI IDs are normally used for other SCSI devices such as this Barracuda disc drive. Most Barracuda disc drives are factory set with the SCSI ID set at 0. To change the SCSI ID, refer to the appropriate drive section for your model. NOTE Most SCSI controllers (host adapters) allow you to skip a SCSI ID. For example, you can have ID0, ID1, and ID3 (skipping ID2). Other controllers do not allow this; refer to your system or controller user's manual for details about its requirements for proper SCSI device installation. After completing the installation process, if the drive's LED does not show on/off activity when the host is trying to communicate with the drive, a duplicate SCSI ID may be the problem. If this is the case, change the ID so that each device on the SCSI chain has its own unique ID. Also check your system or controller user's manual to ensure that you have not violated its SCSI ID numbering recommendations. Drive termination ----------------- If you are installing the drive in a system that has other SCSI devices installed, terminate only the end devices on the SCSI chain. A SCSI "device" is any disc drive, scanner, tape backup unit, or other piece of hardware connected to your system using the SCSI bus. Terminator power ---------------- You usually will not need to change this option and can normally leave the drive configured as it was shipped from the factory. Synchronizing spindles ---------------------- If you are installing two or more Barracuda drives, you may synchronize their spindles to reduce the latency associated with switching from one drive to another. Spindle sync cables are used to connect the drives. After connecting each drive with spindle sync cables, designate a master spindle sync reference source. This master source is usually a disc drive located on the same SCSI bus as the other drives you want to synchronize with. To designate a drive as the master, use SCSI interface commands. Other applicable jumper options ------------------------------- Barracuda 4 drives are designed for use in a variety of systems. Some installations may require you to change one or more of the other jumpers to meet specific system requirements; however, in most cases, you will not need to change any of these jumpers for normal drive operation. Providing adequate cooling -------------------------- The enclosure design must ensure adequate cooling for the drive. The maximum ambient temperature is 50 o C. Terminating the W/WD drive -------------------------- Terminating the drive To terminate the ST15150W drive, enable the permanently mounted IC active terminators by installing an Enable Drive Terminator jumper on J4 pins 11 and 12. If you install one of these models and it is not on the end of the SCSI bus, remove the jumper to disable the permanently mounted IC terminators and thereby remove internal termination from the drive. The ST15150WD drive does not have internal terminators or any way of adding internal termination. You must provide external active termination (ANSI SCSI-2 Alternative 2) to the drive when termination is required. W/WD drives Terminator power ---------------------------- There are four possible terminator power configurations for the ST15150W drive. You will not normally need to change this option and can leave the drive configured as it was shipped from the factory. The ST15150WD drive should be configured with a jumper connecting J01 pins 1 and 3 (and no jumper on J01 pins 2 and 4). WC/DC drives Connecting remote LED ---------------------------------- Remote LED connections are provided on the J4 connector. You can connect 2-pin remote LEDs using these connections. Attach the (-) lead to the appropriate pin and then attach the (+) lead to the pin labelled +5V. ********************************************************************** I N S T A L L ********************************************************************** SEAGATE ST15150 PRODUCT MANUAL Notes On Installation ===================== Mounting the drive and connecting cables ---------------------------------------- Note. This mounting procedure does not apply to WC or DC model drives. To mount a WC or DC drive, plug the drive into the system's singleconnector attachment (SCA) position on the system's back panel. Do not touch the connector pins or any components on the control board without observing static-discharge precautions. Always handle the drive by the frame only. The drive may be mounted in any orientation (horizontally, vertically, and any combination thereof); however, you must ensure that the drive receives adequate air flow for cooling. Mount the drive to the host system's chassis using four 6-32 UNC screws. Two mounting holes are in each side of the drive and there are four mounting holes in the bottom of the drive. The maximum length that the screws should extend into the chassis mounting holes is 0.15 inch (3.81 mm), measured from the outer surface of the chassis. Tighten the screws down evenly. Do not over tighten or force the screw if it does not seem to screw in easily, because this means the threads are not properly aligned. In this case, back the screw out and try again. ********************************************************************** F E A T U R E S ********************************************************************** SEAGATE ST15150 PRODUCT MANUAL General description ------------------- The drive is a component for installation in an enclosure designed for the drive. This is often a rack within the system or an external enclosure designed to house one or more disc drives. In either case, the disc drive must receive adequate cooling and it must be sufficiently grounded and shielded from emissions. SCSI ID ------- Most SCSI controllers (host adapters) allow you to skip a SCSI ID. For example, you can have ID0, ID1, and ID3 (skipping ID2). Other controllers do not allow this; refer to your system or controller user's manual for details about its requirements for proper SCSI device installation. After completing the installation process, if the drive's LED does not show on/off activity when the host is trying to communicate with the drive, a duplicate SCSI ID may be the problem. If this is the case, change the ID so that each device on the SCSI chain has its own unique ID. Also check your system or controller user's manual to ensure that you have not violated its SCSI ID numbering recommendations. Providing adequate cooling -------------------------- The enclosure design must ensure adequate cooling for the drive. The maximum ambient temperature is 50*C. The evaluation consists of ensuring that the case temperature of certain critical components remains within acceptable limits during drive operation. We recommend orienting the drive or directing the air flow in a way that creates the least amount of air flow resistance while providing air flow above the circuit boards and around the head and disc assembly (HDA). Also, choose the shortest possible path between the air inlet and exit. This minimizes the distance traveled by air that is heated by the drive and by other nearby heat sources. ********************************************************************** 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.
