Start/Stop option
-----------------
When a jumper is installed on pins 9 and 10, the drive waits for a
Start Unit command from the host before starting the spindle motor.
The spindle motor is also stopped using this command.

UNACCEPTABLE! UNACCEPTABLE!
Never install PC board on the Top!
The drive may be mounted horizontally with the PC board down or on
either side. Mounting vertically on either end is a prohibited orien-
tation.
For optimum performance, the drive should be formatted in the same
position as it will be mounted in the host system.
Do not mount the drive vertically on either end.
Shock and vibrations
--------------------
All shock and vibration specifications assume that the drive is moun-
ted in an approved orientation with the input levels at the drive
mounting screws.
During normal operating shock and vibration, there is no physical
damage to the drive and performance is not degraded.
During abnormal operating shock and vibration, there is no physical
damage to the drive, although performance may be degraded during the
shock or vibration episode. Drive performance will return to speci-
fications when normal operating shock levels resume.
Handling and Static-Discharge Precautions
-----------------------------------------
After unpacking, and prior to system integration, the drive may be
exposed to potential handling and ESD hazards. It is mandatory that
you observe standard static-discharge precautions. A grounded wrist-
strap is preferred. Handle the drive by the frame only and always
rest the drive on a padded surface until it is mounted in the host
system.
Caution: to avoid potential service problems, observe the following
precautions:
- Handle the drive by the edges or frame. Do not put pressure on the
top cover or touch the circuit board.
- Do not remove or cover factory-installed labels. They contain in-
formation needed to service the product.
- Do not put labels over the brather holes on the top surface of the
drive. The breather holes must remain clear to allow air to circu-
late.
- If a label, other than a factory-installed label, has been placed
over the breather holes, remove it. Do not poke holes through the
label. This damages the filter underneath, allowing contaminants
to enter the drive.
- Do not use solvents to remove the adhesive residue from drive
labels. Small amounts of solvent may get into the unit and conta-
minate the disc.
- Do not plug a live DC power cabel into the drive power connector.
This damages the connector contacts.
Terminators
-----------
There are three internal drive I/O termination SIP resistor modules
that plug into sockets on the PC board. You can order the drive with
or without these terminators, depending on the application. All
single initiator/single target applications require that the
initiator and drive be terminated. Daisy-chain applications require
that only the units at each end of the daisy-chain be terminated. All
other peripherals on the chain should not be terminated.
Note: Remove terminator resistor packs where terminators are not
required. Removal of terminator power source selection jumper does
not disconnect the terminator resistors from the circuit.
Terminator Power
----------------
The drive can be configured to supply terminator power for the SCSI
Bus. The drive also may be configured to accept terminator power via
Pin 26 of the SCSI bus or to provide terminator power for optional
internal termination resistors via the drive power connector. If
terminators are installed, jumpers must also be installed.
