When daisy- chaining two drives, specify one as the Master, the other as the Slave, using the Drive Select (C/D) jumper pins on the drives: To configure a drive as the Master (Drive 0), a jumper could be installed at the C/D pins. Samsung ships SHD-3121A/3122A hard disk drives from the factory with the C/D jumper installed (Drive 0). To specify a drive as the Slave (Drive 1), remove the C/D jumper. Note. The order in which drives are connected in a daisy chain has no significance. DSP Drive Slave Present Jumper ------------------------------- In combination with the current C/D jumper setting, the DSP jumper implements one of two possible configurations: When the drive is configured as a Master - that C/D jumper is installed, the DSP jumper informs the drive that a Slave drive is present. The DSP jumper should be installed on the Master drive only if the Slave does not use the Drive Active/Slave Present (DASP-) signal to indicate its presence. When the drive is configured as a Slave, both the C/D and DSP jumpers are not to be installed. Faceplate LED Operation ----------------------- Whenever the drive initiates the execution of a command, a green LED on the faceplate light, and remains lit until the execution of the command is complete or aborted. ********************************************************************** I N S T A L L ********************************************************************** SAMSUNG SHD-3121A/3122A PRODUCT MANUAL 264 034001 BAAC Notes on installation ===================== Installation direction ---------------------- horizontally vertically +-----------------+ +--+ +--+ | | | +-----+ +-----+ | | | | | | | | | +-+-----------------+-+ | | | | | | +---------------------+ | | | | | | | | | | | | | | | | | | +---------------------+ | +-----+ +-----+ | +-+-----------------+-+ +--+ +--+ | | | | +-----------------+ The mounting holes on the SHD-3121A/3122A hard disk drive allow the drive to be mounted in any orientation. For mounting, #6-32 UNC screws should be used. Caution: The printed circuit board (PCB) is very close to the mounting holes. Do not exceed the specified length for the mounting screw. The specified screw lenght allows full use of the mounting- hole threads, while avoiding damaging or placing unwanted stress on the PCB. To avoide stripping the mounting-hole threads, the maximum torque applied to the screws must not exceed 8 Kg-cm (6.95 inch- pounds). Samsung ships the SHD-3121A/3122A hard disk drive with a faceplate installed. Ventilation ----------- The SHD-3121A/3122A hard disk drive operates without a cooling fan, provided the ambient air temperatur does not exceed (55*C). Any user- designed cabinet must provide adequate air circulation, to prevent the maximum temperature from beeing exceeded. J1 AT-Bus Interface Connector ------------------------------ On the SHD-3121A/3122A hard disk drive, the AT-bus interface cable connector (J1) is a 40-pin male Universal Header. To prevent the posibility of its incorrect installation, the connector should be keyed by removing Pin 20. This will ensure that the connector cannot be installed upside down. All signals are relative to pin 20. For the mating female J1 connector, recommended cable connectors include AMP receptacle P/N 1-499506-0, with strain relief: P/N 1-746193-0, without strain relief; or an equivalent. To key the cable connectors, you must plug the connector that corresponds to Pin 20. Other recommended part numbers for the mating connector include: 40-Pin Connector 3M 3417-7000, or equivalent Strain Relief 3M 3448-2040, or equivalent Flat Cable (Strained 28 AWG) 3M 3365-40, or equivalent Flat Cable (Strained 28 AWG) 3M 3517-40 (shielded), or equivalent J5 DC Power Connector --------------------- The drives DC power connector (J5) is a 4-pin Elco Electronics Connector P/N 01-9091-0408-05-808, or equivalent, mounted on the back edge of the printed-circuit board (PCB). Recommended connectors and their numbers: 4-Pin connector (P2): AMP P/N 1-480424-0, or equivalent Loose-pice contacts: AMP P/N 61173-4, or equivalent Strip contacts: AMP P/N 350078-4, or equivalent pin 1 +12 VDC pin 2 +12 V Return (Ground) pin 3 + 5 V Return (Ground) pin 4 + 5 VDC Note: Labels indicate the pin numbers on the connector. Pins 2 and 3 are connected on the drive. -------------------------------+ -----J1-----1+ +-----J5-----+| ::::::::::::| | 4 3 2 1 || -----------2+ +------------+| ----------------------------+ AT-Bus Interface Characteristics -------------------------------- The AT-Bus interface supports one or two hard drives per adapter board, and a maximum of two adapter boards - or a maximum of four drives. Electrical Characteristics -------------------------- All signals are TTL-compatible - with logic one greater than 2.0 volts and less than 5.25 volts; and logic zero greater than 0.0 volts and less than 0.7 volts. Neither the adapter board not the drives require terminating resistors. Adapter Board Installation ========================== The adapter board is a half-size board and can be installed in any available 16-bit slot in an IBM PC-AT or compatible. Before install- ing the adapter board, make sure that no other hard drive controller resides at the primary hard drive address, 1F0H-F7H. If a combination floppy and hard drive controller is present, the hard drive controller functions on the floppy/hard drive controller must be disabled. To disable hard drive controller functions on a floppy/hard drive controller, follow these instructions: - On a Western Digital WD1002-WA2 or WD1003-WA2 floppy/hard drive controller card: 1. Do not install jumpers on pin E5 and E6. Install jumpers on pins E4 and E5, to ensure that the controller card resides at the secondary address, 170H-177H, rather than at the primary, 1F0H- 1F7H. 2. Move the card from a 16-bit I/O slot to disconnect the IRQ14 output driver. - On a DTC (Data Technology Corporation) floppy/hard drive controller card: 1. Install a jumper on pins W3. 2. Move the card from a 16-bit I/O slot to disconnect the IRQ14 output driver. Connecting the Adapter Board and the Drive ------------------------------------------ Use the ribbon cable supplied with the adapter board to connect the drive to the board. To ensure that the cable is plugged into the adapter board and the drive correctly, there is a red wire at one edge of the cable. To connect the drive to the board: 1. Note the number 1 printed on the board next to the connector. When one end of the cable into the connector on the adapter board, make sure the red wire on the cable is at the side of the connector labeled 1. 2. When inserting the other end of the cable into the connector on the drive, makes sure the red wire is at the inside edge of the drive connector, next to the J5 power connector. To complete the installation of the drive, secure it to the system chassis using the mounting screw. ********************************************************************** F E A T U R E S ********************************************************************** SAMSUNG SHD-3121A/3122A PRODUCT MANUAL 264 034001 BAAC Introduction ------------ SHD (Samsung Harddisk Drives) 3121A/3122A hard disk drive is a high performance, 1-inch-height form factor with the highest product- ability and quality. This uses 3 inch rigid disks, and is available with AT (Advanced Technology) interface. The SHD-3121A/3122A features and embedded AT commands to optimize system performance. Because the drive manages media defect and error recovery internally, these operations are fully transparent to the user.
