Jumper Setting
==============
TERMPWR (Terminator Power)
--------------------------
NOTE
LR Models do not provide TERMPWR to the SCSI bus. The RAID connector
does not accommodate this feature.
SCSI Bus Termination
--------------------
Both ends of the SCSI bus cable must be terminated. One end is
terminated at the host. The other end must be terminated by the last
SCSI device on the SCSI bus.
Drive Termination
-----------------
DSP3000L Series drives contain internal components to provide active
termination of the SCSI bus.
When this drive is the last device on the SCSI bus, configure the
drive to enable active termination. Do so by installing a shunt
jumper at the drive's active termination header. If active
termination is not required for this drive, make sure that the
jumper is not installed.

SCSI ID (Address) Selection
---------------------------
Each device on the SCSI bus must have a unique SCSI ID number
assigned to it.
ID number for L/LD models (8-bit SCSI) range from 0 through 7. For
LW/LWD models (16-bit SCSI), the numbers range from 0 through 15.
SCSI ID numbers for LR models range from 0 through 7 for 8-bit
configurations and from 0 through 15 for 16-bit configurations.
Configure the SCSI ID of L/LD/LW/LWD models by installing jumper
across the indicated Option connector pins. For LR versions, provide
the proper open or ground signal input to the referenced pins of the
drive's 80-pin RAID connector.

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.
Except when connecting several drives together for a spindle
synchronization application, do not connect the ground signals of two
or more drives together or to any other current source using the
Option connector. Doing so may introduce ground loop problems.
The following optional features can be configured according to your
system requirements. These features (model-dependent) include:
- Notification of AC power failure (not currently supported by LR models. SCSI RST may be used instead.)
- Spindle synchronization
- Write protection (not currently supported by LR models)
- Spin delay
AC Failure Notification
-----------------------
The AC Low connection (AC_LOW L) is not currently supported on LR
models, SCSI Bus Reset provides the alternative to the AC Low
warning.
Spindle Synchronization
-----------------------
DSP3000L 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 DSP3107L only with
another DSP3107L drive. Do not connect the SPINDLE_SYNC_REF L 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.

Spin Delay
----------
The method for establishing spin-up characteristics is dependent upon
the drive model.
Spin Delay - LR Models
----------------------
Spin delay (spin-up) characteristics for LR models are determined by
the state of the RMT_START (pin 38) and DLYD_START (pin 78) inputs to
the 80-pin RAID connector. The states of these signals are set by
using either hard-wired connections at the backplane or backplane
logic.
Spin-up characteristics are configured to provide one of the follo-
wing options.
- Spin-up at drive power on (Option 1)
- Spin-up upon receipt of SCSI Start command (Option 2)
- Spin-up after a predetermined delay following power up. Delay is equal to 12 seconds (typical) times the drive's numeric SCSI ID (Option 3)
NOTE
LR models that do not implement any of the listed spin delay options
should be configured for Option 2.
The following chart describes spin-up characteristics for LR model
drives:

Remote Features
---------------
DSP3000L Series drives support the following remote features, which
can be configured at the drive's Option connector or RAID backplane:
- Remote SCSI ID selection
- Remote LED status display
Remote SCSI ID Selection
------------------------
SCSI ID can be set remotely from an external (remote) switch or
control panel. For L/LD/LW/LWD models, this is accomplished using the
Option connector. For LR models, the output of the remote or external
ID switches takes the place of jumpers or circuits at the RAID system
backplane.
To configure LR models, connect the output of the remote or external
switch to the RAID backplane instead of using backplane jumpers or
circuits.
Remote LED Status Display
-------------------------
LR models provide the ACTIVITY LED OUT signal which can be used to
drive a user-supplied remote LED.
ACTIVITY LED OUT signal - LR Models
-----------------------------------
LR models do not contain a busy or fault LED. Rather, they provide an
output to drive a user-supplied activity LED.
The ACTIVITY LED OUT signal indicates the drive is performing a SCSI operation. Connect the cathode of the user-supplied LED to the ACTIVITY LED OUT connection. The LED anode must be attached to the proper +5 VDC supply through an appropriate current-limiting resistor.

You can mount the disk drive in any position. LR models mount in RAID
storage subsystems. The drive (with bezel) attaches to the system bay
and accept #6-32 screws. Screws should not exceed 0.25 inch
(6.25 millimeters) in length, otherwise damage to the PCB may result.
Mounting and Bezel Options
--------------------------
Bezels and mounting brackets are available from Digital Equipment
Corporation for mounting the drive in either 3.5-inch or 5.25-inch
form factor bays.

Product Summary
---------------
DSP3000L Series 3.5-inch Disk Drives are high-performance, high
capacity drives, designed and manufactures by Digital Equipment
Corporation.
Features
--------
Features of the DSP3000L Series drives include the following:
- Formatted capacity ranging from 535 MB to 1,377.5 MB, depending upon model
- 1 millisecond track-to-track seek time
- 512 KB segmented cache buffer
- End-to-end Error Detection Code/Parity on cache RAM
- Four headers per sector
- Embedded quadrature servo
- Self-diagnostics
- Down-loadable SCSI firmware
- Tagged command queuing
- Seek ordering
- Automatic block realloction
- Glitch-free power on/off operation
- Synchronized spindle operation
- Low power consumption
Power-On Tests
--------------
After power is applied, and before spin-up is completed, the drive
performs self-test diagnostics prior to making itself visible on the
SCSI bus. These intitial self-test check most of the electronics that
control HDA, but not the SCSI transceiver or SCSI connector.
After spin-up, additional tests complete self-test coverage of the
electronics module and the HDA. The unit appears not ready to the
host between completion of the initial self-tests and completion of
the drive's post spin-up tests.

LED Indicators
--------------
The green Busy LED illuminates to signify the drive is working on a
SCSI command. 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 on-line 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.
