The connector is normally used in conjunction with jumpers which are supplied. The jumpers are placed in the connector to select the desired SCSI address and operating options. +Fault LED Front View --++---+2---------+------------------------ Busy LED+ |:::.::::::| Option Connector +1--------19-------------------- Spindel Synchronization +++ +------ SPINUP Jumper SCSI ID SCSI Bus Address Selection -------------------------- Three pairs of pins on the option connector set the disk drive's address on the SCSI bus. The drive accepts addresses 0 through 7. You must assign a unique address to each device on a SCSI bus. Typically, the first drive on the bus is assigned address 0, the second drive address 1, and so on. SCSI address 7 is usually reserved for the host adapter.

Alternatively, the drive's terminator resistor packs can be powered from the SCSI bus. In all cases, the drive's terminator resistor packs are to be installed ONLY if the drive is at the end of the SCSI bus. Generally, the host is the only device on the SCSI bus required to provide TERMPWR for the bus. To ensure that there is a sufficient level of power along the entire SCSI bus, Digital Equipment Corporation recommends that all devices on the SCSI bus supply TERMPWR (if they are capable). SCSI devices are protected by a diode or similar semiconductor to prevent back flow of the terminator power when more than one device supplies this power.

One end is terminated at the host. The other end must be terminated by the last SCSI device on the SCSI bus. Note Do not install Models DSP3105D (differential) or DSP3210WD (wide, differential) at the end of the bus. DSP3105D and DSP3210WD drives can not provide bus termination. Configure Optional Features --------------------------- CAUTION The 5-volt signals of two or more drives should not be connected together or to any other current source by using the Option connector. Doing so may cause drive malfunction or component damage. Care must be taken when connecting the ground signals of two or more drives together to avoid ground loop problems. Ground loops may cause drive malfunction. The following optional features can be configured according to your system requirements. These features include: - Notification of AC power failure - Spindle synchronization - Write protection - Spin delay Option Connector Spindle Synchronization ---------------------------------------- Use Pin 19 of the option connector to connect the drive for optional synchronized spindle operation. The drive operates either as a Master, generating a reference signal on Pin 19, or as a Slave, re- ceiving a reference signal on Pin 19 from another drive or other source. Master or Slave operation modes are set through the SCSI interface. The drive always maintains local speed regulation when no reference signal is applied. Spindle Synchronization ----------------------- DSP3000 Series drives support synchronized spindle operation. Master or slave synchronized operation is set through a SCSI Mode Select Page. When the drive operates as a Master, it generates a spindle synchronization reference signal (SPINDLE_SYNC_REF L). When operating as a slave, the drive synchronizes its spindle according to the SPINDLE_SYNC_REF L input reference. The drive always maintains local speed regulation when no reference signal is applied. NOTE The reference signal must originate from drives with the same electronics modules. Fo example, connect Model DSP3160 only with another DSP3160 drive. Do not connect the SPINDLE SYNC signal so that of any other model disk drive. Otherwise, the drive may mal- function. When connecting multiple drives together for spindle synchronization, be sure to use proper cabling techniques to avoid ground loop problems. Spindle Sync Connection ----------------------- The following figure shows the SPINDLE SYNC and associated ground connection pin on the Option connector. Option Connector +---------20 |*** @oooo*| * = LOGIC_GND L (Pins 2,4,6,20) |ooooooooo@| @ = SPINDLE_SYNC_REF L (Pins 10,19) +1---------+ For Models DSP3085/3105/3105D, pin 10 is provided as an alternate SPINDLE SYNC connection to facilitate installations where a 10-pin header is used to connect several remote features. Pin 19 is provided to facilitate the use of a 2-pin connector for SPINDLE SYNC connections. The ground return is pin 20, although pins 2, 4, or 6 can be used for the ground return. Option Connector SPINUP Jumper ------------------------------ The disk drive spins up when you install a jumper across pins 13 and 14 of the option connector and apply power. Without the jumper, the drive waits for a START STOP UNIT command before spinning up. The disk drive spins down when power is removed, when a fault condition is detected, or in response to the START STOP UNIT command. 13,14 CLOSED Spin up when power is applied OPEN Wait for START UNIT command DSP3000 Series drives support either the Write Protect or Spin Delay mode. If your drive supports the Spin Delay mode, you can program the drive automatically spin-up at powere on by installing the jumper across the referenced Option connector pins. To have spin-up controlled by a Start/Stop Unit command, remove the jumper. +---------20 |ooo ooXooo|Option Connector |ooooooXooo| +1---------+ Write Protection ---------------- DSP3000 Series support either the Write Protect or Spin Delay mode. If your drive supports the Write Protect mode, install the jumper across the referenced pins of the Option connector. To disable Write Protection from 8-bit drives, remove the jumper from across 13 and 14 of the Option connector. Note that when the Write Protect Mode bit is set to a 1, automatic spin up occurs at power on. +---------20 |ooo ooXooo|Option Connector |ooooooXooo| +1---------+ Remote Options -------------- You can also use the option connector to connect the drive for various remote capabilities when the necessary user-provided facilities are available. - SCSI address selection from external switches; for example, from an operator control panel. - Busy and Fault conditions monitoring, using external LED indicators instead of those on the drive. - Remote power supply notification to the drive of ac power failure. Remote SCSI ID Selection ------------------------ The Option connector enables you to set the drive's SCSI ID from an external (remote) switch or control panel. Configure the drive for remote ID selection by removing the SCSI ID jumpers (if present) from the SCSI ID pins. Then connect the leads from the external selection switch to the referenced pins. Observe the following guidelines while doing so. - ID bit 0, at Pin 1, is the Least Significant Bit. - SCSI ID bits 0, 1, 2, and 3 are active LOW signals. That is, the bit is a 1 if the corresponding remote switch is closed to ground. - For Models DSP3085/3105/3105D/3160/3210, use pins 2, 4, and 6 as the associated ground returns for ID bits 0, 1, and 2 respectively. They can be used individually, or the ground returns of all three ID bits can be combined at pin 2, 4, or 6. Option Connector +---------20 |*** oooooo| * = LOGIC_GND L (Pins 2,4,6) |@@@ooooooo| @ = SCSI ID <0>,<1>,<2>, L +1---------+ (Pins 1,3,5) LED Indicators -------------- The disk drive has two surface-mounted LED indicators: Busy (BSY) which is green and Fault (FLT) which is amber. The BSY LED indicates that the drive is working on a SCSI command. It is not equivalent to the SCSI BSY signal. The FLT LED idicates a drive fault condition. It is normal for both LEDs to light briefly upon application of power. Remote Busy and Fault Status Display ------------------------------------ The drive's Busy and Fault status can be monitored by connecting a remote Busy and a remote Fault display LED to the drive's Option connector. Remote Busy ----------- The remotely monitor Busy status of the drive, connect the cathode side of the remote Busy LED to the BSY_OUT L pin. The anode side of the LED connects to the +5VDC OUT pin. Remote Fault ------------ The remotely monitor Fault status of the drive, connect the cathode side of the remote Fault LED to the FLT_OUT pin. The anode side of the LED connects to the +5VDC OUT pin. Option Connector +---------20 |ooo oooooo| |ooo***oooo| +1--+++----+ ||+-- +5 VDC OUT |+--- BSY_OUT L +---- FLT_OUT L AC Failure Notification ----------------------- The host system (or power supply) can warn the drive of an impend- ing AC failure by asserting the signal AC_LOW L. This is an active low signal (low means power failure). NOTE The system should provide this warning at least 10 milliseconds prior to failure for this feature to be operational. To utilize this feature, connect the system's AC power warning signal to the referenced AC_LOW L pin on the Option connector. When the host system asserts the AC_LOW L warning to the drive, the drive prevents write-spliced for outstanding writes.

CAUTION: The mounting screws should not protude more than four threads beyond the inside surface of the drive frame. Screws longer than specified can disable the shock mounting process and damage the drive.

The amber Fault LED indicates a fault status. Both the Busy and Fault indicators light briefly during power up. This serves as a hardware and lamp test. During a calibration operation, the Busy LED is illuminated and the Fault LED flashes. Calibrations occur following some firmware up- grades. Generally, calibration periods last only about five minutes, after which the drive comes online and both indicators go out. If the Fault indicator lights at any other time, the drive has failed and likely requires service (unless the Fault LED was turned on by means of a MODE SELECT command). Remote Busy and Fault indicators can be connected to the Option connector to provide status display at a remote location or panel. Power-On Tests -------------- After power is applied, and before spinup is completed, the drive performs selftest diagnostics prior to making itself visible on the SCSI bus. These intitial selftest check most of the electronics that control HDA, but not the SCSI transceiver or SCSI connector. After spinup, additional tests complete selftest coverage of the electronics module and the HDA. The unit appears not ready to the host between completion of the initial selftests and completion of the drive's post spinup tests.
