Before unpacking or handling the drive or attempting any installation, please read through this manual, including all warnings and cautions. The Model DSP5200 is a full-height 5.25 inch disk drive with a formatted capacity of 2000 megabytes and a single-ended (S) or differential (D) SCSI-2 interface. The Model DSP5350 is a full-height 5.25 inch disk drive with a formatted capacity of 3570 megabytes and a single-ended (S) SCSI-2 interface. ------------------------------------------------------------ CAUTION ------------------------------------------------------------ Handle the disk drive with care. Observe antistatic precautions. Static electricity can damage integrated circuits. Always use a properly grounded wrist strap and antistatic pad when removing the disk drive from its antistatic bag and handling it outside the bag. ------------------------------------------------------------ 1 2 SCSI Address and Options Selections An option connector on the printed circuit module is used to set the SCSI address and select the various operating options that are described in the following paragraphs. Jumpers are placed across specific pins in the connector to select the desired SCSI address and operating options. The connector and various jumper placements are shown in the figures that follow. 2 SCSI Bus Address Selection Three pairs of pins on the option connector are used to set the disk drive's address on the SCSI bus. The drive will accept addresses 0 through 7. Each device on a SCSI bus must be assigned a unique address. Typically the first drive on the bus is assigned address 0, the second drive address 1, and so on. SCSI address 7 is typically reserved for the host adapter. 3 Spin Up Option Selection When a jumper is installed across pins 13 and 14 of the option connector the disk drive will spin up when power is applied. Without the jumper the drive waits for a START UNIT command before spinning up. The disk drive spins down when power is removed or when a fault condition is detected. Firmware Load Option Selection The capability to update the drive's internal flash ROM has been provided to allow firmware updates to be made in the field. In order to update the flash ROM the following steps should be taken: 1. Apply power to the drive. 2. Install the jumper across pins 19 and 20 of the option connector. 3. Load the firmware update. 4. Remove jumper when the update is complete. Power should NOT be applied to the drive with the jumper installed. 4 LED Indicator Options Selections The bottom rear of the disk drive has two surface mounted LED indicators, busy (BSY, green) and fault (FLT, amber). These indicators are operational only when jumpers are installed as described below. The busy LED indicates that the drive is working on a SCSI command. It is not equivalent to the SCSI BSY signal. The fault LED indicates a drive fault condition. It is normal for both indicators, if enabled by their jumpers, to light briefly upon application of power as a lamp test. 5 Remote Options The option connector can be used to remotely control or monitor certain drive functions. When the remote control panel is to be used, jumpers are removed from the option connector and are replaced by a cable(s) to the remote panel. The supported remote options include: · Selection of SCSI address from external switches, such as on an operator control panel. · Monitoring busy and fault conditions with external LED indicators instead of those on the drive. (The user must provide external current-limiting resistors to limit the current to 6mA or less. No current limiting resistors are necessary if the LED is rated to handle up to 7 mA maximum.) A front bezel with a BUSY LED mounted may have been installed at the factory. The associated cable has to be connected to the option connector in the following manner: black lead to pin 9 and red lead to pin 11. ------------------------------------------------------------ Note ------------------------------------------------------------ In this case no current-limiting resistors are needed. ------------------------------------------------------------ · Remote power supply notification to the drive of AC power failure. If the power supply warns the drive at least 1.0 milliseconds before the voltages become unsafe, the drive will prevent write splices (write interruptions within a data sector). Unsafe voltages levels (measured at the drive connector) are voltages outside the following; 4.690 to 5.557 for the +5Vdc supply 10.994 to 13.399 for the +12Vdc supply 6 The following diagram shows proper connection of remote options. 7 Spindle Synchronization Option (DSP5350 only) Spindle synchronization for the DSP5350 is enabled by the installation of a daisy-chain cable from drive to drive. This cable should connect pin 21 to the daisy-chained SPINDLE_SYNC_REF SIGNAL, using pin 22 as its ground reference. 8 3 SCSI Bus Termination DSP5200 Termination The DSP5200 disk drive can provide terminator power to its own termination resistor packs (if installed) and/or to the SCSI bus. Alternatively, the drive's termination resistor packs can be powered from the SCSI bus. The figure below shows the proper jumper arrangements for each terminator power configuration. In all cases, the drive's termination resistor packs are to be installed ONLY if the drive is at the end of the SCSI bus. 9 The following figure shows the proper placement of the termination resistor packs on the drive module. NOTE THAT: S (single-ended) units use 8-pin packs D (differential) units use 14-pin packs 10 DSP5350 Termination The DSP5350 disk drive is capable of supplying termination power to the SCSI bus, as well as providing active termination to the bus. The DSP5350 drive does not use removable resistor packs for termination. The figure shows the proper jumper arrangements for each terminator power configuration. Active termination should be enabled ONLY if the drive is at the end of the SCSI bus. 11 4 Power Connections and Requirements Each disk drive requires +5 and +12 volt DC which is supplied from an external source by means of the 4-pin power connector of the drive. 12 Voltage & Regulation: +5VDC ------------------------------------------------------------ +12VDC ------------------------------------------------------------ DSP5200S DSP5200D DSP5350 ±5% ±5% ±5% ±5% (±6% during spin-up) ±5% (±6% during spin-up) ±5% (±5% during spin-up) Ripple & Noise: +5VDC ------------------------------------------------------------ +12VDC ------------------------------------------------------------ DSP5200S DSP5200D DSP5350 <100mv p-p <100mv p-p <75mv p-p <200mv p-p <200mv p-p <150mv p-p Current: +5VDC Current ------------------------------------------------------------ Typical ------------------------------------------------------------ Maximum ------------------------------------------------------------ DSP5200S DSP5200D DSP5350 1.0A 1.4A 1.0A 1.2A 1.6A 1.2A +12VDC Current ------------------------------------------------------------ Typical ------------------------------------------------------------ Maximum ------------------------------------------------------------ Spin-up Spinning--no seeks Continuous random seeks 4.3A 1.0A 1.5A 5.0A 1.2A 1.8A Power: Total power with continuous random seeks ------------------------------------------------------------ Typical ------------------------------------------------------------ Maximum ------------------------------------------------------------ DSP5200S DSP5200D DSP5350 22.9W 25.0W 35.0W 28.4W 30.5W 40.8W 13 5 Mounting The disk drive may be mounted in any orientation. Allow 0.10 inches clearance between the HDA and all adjancent surfaces, and sufficent slack in all cables, to provide for motion of the drive on its shock mounts relative to the drive frame. The drive is mounted with four 6-32 screws. The mounting screws should not exceed more than 0.02 inches beyond the inside surface on the drive frame. ------------------------------------------------------------ CAUTION ------------------------------------------------------------ Screws longer than necessary will defeat the shock mounting and could damage the drive. ------------------------------------------------------------ 14 6 Summary of Specifications 15 16
