Preface
This manual contains information for users of the Seagate®
Medalist Pro SCSI disc drives. It provides support services, performance specifications, and initial setup information. Additional
informat io n is availa ble in the
number 32661-001). Contact your Seagate sales representative
if you need to ord er t his publicati on.
Handling precautions
• Disc drives are fragile. Do not drop or jar the drive. Use a
padded surface during installation to avoid damaging the
drive.
• Keep the drive in its antistatic bag until you are ready to
install it .
• Protect the drive from static discharge by making sure you
are well grounded before touching the drive. We recommend
wearing a grounded wrist strap (Seagate part number
12263496) throughout the installation process. Do not touch
the connectors or any part of the printed circuit board.
• Alwa ys handle the drive by its edges or frame.
• Do not apply pressure or attach labels to the circuit board or
the top of the drive.

Electrostatic discharge protection
Caution.
All drive electronic assemblies are sensitive to static electricity,
due to the electrostatically sensitive devices used within the
drive cir cui try. Although some devices such as metal-oxide semiconductors are extremely sensitive, all semiconductors, as well
as some resi stors and capacitors, may be damaged or deg raded
by exposure to static electricity.
Electrost atic damage t o electr onic de vices may be caus ed by the
direct discharge of a charged conductor or by exposure to the
static fields surrounding charged objects. To avoid damaging
drive electronic assemblies, observe the following precautions
when installing or servicing the drive:
• Ground yourself to the drive whenever the drive electronics
are or will be expos ed. Connect yourself to ground with a wrist
strap (Seagate part number 12263496). Connection may be
made to any grounded metal assembly. As a general rule,
remember that you and the drive electronics must all be
grounded to avoid potentially damaging static discharges.
• Turn off the power before removing or installing the DC power
cable.
• Do not remov e any circuit boards from the drive.
• Never use an ohmmeter on any circuit boards.
• When installing th e drive on a carrier or t ra y, discharge the car-
rier or tray pr io r to ins e rting it into th e sy st e m.
Removal of circuit boards by personnel not performing depot repair will damage components and may
void the war ranty.
Medalist Pro Installation Guide, Rev. B 3
Important safety information and precautions
Caution.
Use proper safety techniques for safe, reliable operation of this
unit.
The procedures in this manual and labels on the unit contain
warnings and cautions that must be carefully read and followed
to minimize or eliminate the risk of personal injury. The warnings
point out conditions or practices that may endanger you or others. The cautions point out condit ions or practices that m ay damage the unit, poss ibly making it unsafe for use.
Always observe the foll owing warnings and pre cautions:
• Follow all cautions and warnings in the procedures.
• Use sound safety practices when operating, installing, or
removing the unit.
• Use caution when troubleshooting a unit that has voltages
present. Turn off power to the unit before removing it.
• Ensure that the internal temperature of the rack or cabinet
does not exceed the limits defined for the drive when the drive
is mounted in an equipment rack or cabinet. When units are
stacked vertically, pay special attention to the top where temperatures ar e usually highest.
• Follow the precautions listed above in “Electrostatic discharge
protection.”
• Do not remove any circuit boards from the drive. Return the
entire drive for depot repair if any circuit board is defective.
Removal of circuit boards by personnel not performing depot
repair will damage components and may void the warranty.
Use forced-air ventilation when bench-testing the
drive to ensur e proper cooling of drive com ponents.
4 Medalist Pro Installat ion Guide, Rev. B
• Do not remove the head and disc assembly (HDA) from the
drive. Return the entire drive for depot repair if the HDA is
defective.
• Do not attempt to disassemble the HDA. It is not field repair-
able. If the sealed HDA is opened by personnel not performing
depot repair, this will damage components and void the
warranty.
As a component, this drive is designed to be installed and operated in accordance with UL1950, EN60950, CSA C22.2 950M89, and VDE0805.
Seagate takes all reasonable steps to ensure that its products
are certifiable to currently accepted standards. Typical applications of these disc drives include customer packaging and subsystem design. Safety agencies conditionally certify component
assemblies, such as the Medalist disc drive, based on their final
acceptability in the end-use product. The subsystem designers
are responsible for meeting these conditions of acceptability in
obtaining safety-regulatory agency compliance in their end-use
products and for certifying where required by law. A necessary
part of meeting safety requirements is the provision for overcurrent protection on drive SELV supply voltages.
This unit is a component part and as such is not meant to comply with FCC or similar national requirements as a stand-alone
unit. Engineering radiated emissions test results are available
through the Seagate Safety Department to assist the subsystem
designer.

General description
Medalist Pro SCSI disc drives are high-speed, random-access
digital-data storage devices.
The drive is a component for installation in an enclosure
designed for the drive. This is often a rack within the system or
an external enclosur e desi gned to house one or more di sc driv es
or other peripheral units. In either case, the disc drive must
receive adequate cooling (refer to “Providing adequate cooling”)
and it must be sufficiently grounded and shielded from emissions. The
001) contains guidelines for a properl y designed enclosure.

SCSI ID jumpers
Each device on the SCSI chain must have a unique SCSI ID.
The host system’s SCSI controller usually uses the ID that has
the highest priority in the SCSI I/O system. This is always ID7.
ID0 is lowest priority in an 8-bit I/O system. ID8 is lowest priority
in a 16-bit I/O system. The lower priority SCSI IDs are normally
used for other SCSI devices such as this Medalist disc dri ve.
Note.
Most SCSI controllers (host adapters) allow you to skip a
SCSI ID. For example, you can have ID0, ID1, and ID3
(skipping ID2). Other controllers do not allow this so be
sure to refer to your system or controller user’s manual
for details about its requirements for proper SCSI device
installat io n .
Note.
This drive is a SCAM (SCSI Configured Auto Magically)
compliant drive. I f the system i nto which you are inst all ing
this drive requires SCAM compliant drives, you do not
need to be concerned about the drive ID jumper settings,
as the system automatically assigns your new drive the
ID it wants i t to have. The system may or may not use the
existing drive ID jumper settings. Setting the drive ID
doesn’t hurt anything, but is not necessary in a SCAM
compliant system.
The Medalist disc drives are factory set wit h the SCSI I D set at 0.
To change the SCSI ID, refer to the appropriate drive section for
your model.
If, after completing the installation process, the drive’s LED does
not show on/off activity when the host is trying to communicate
with the drive, a duplicate SCSI ID may be the problem. If this is
the case, change the ID so that each device on the SCSI chain
24 Medalist Pro Installation Guide, Rev. B
has its own unique ID. Also check your system or controller
user’s manual to ensure that you have not violated its SCSI ID
numbering recomm endations.
Drive termination
If you are installing a Medalist drive in a system that has other
SCSI devices installed, terminate only the end devices on the
SCSI chain. A SCSI “device” is any disc drive, scanner, tape
backup unit, or other piece of hardware connected to your system using the SCSI bus.
The top example in Figure 2 shows an internal hard disc at one
end of the SCSI bus with the SCSI controller at the other end
(both are terminated). The bottom example shows two additional
SCSI devices connected externally—this means the SCSI controller is no longer on the end of the SCSI chain and should not
be terminated.
Note.
Some controller s prefer to remain terminated even if they
are in the middle of the chai n. Also, some control lers treat
the internal and external chains as separate logical
buses. This means you may need to terminate both the
first and last devices on both logical buses to achieve
proper termination. If necessary, refer to your system or
controller documentation to see how this is handled in
your particular system.
Medalist Pro Installation Guide, Rev. B 25
For information about how to terminate your drive, refer to the
appropriate drive-specific section.

You usually will not need to change this option and can normally

information about how to change the terminator power option on
your driv e, refer to th e appropriate drive- specific section.
I/O circuits and data path widths
“W,” “WC,” “LW,” and “LC” models have a “wide” (16-bit) SCSI
data bus rather than the standard (non-wide) 8-bit SCSI data
bus; howe ver , you can use these wide drives on a standard (non wide) 8-bit data bus using a terminated 68-pin to 50-pin SCSI
cable (not applicable to “WC” or “LC” drives which are not to be
connected into the system via cab le).
26 Medalist Pro Installation Guide, Rev. B
Figures 3a, 3b, 3c, and 3d show typical drive connections. The
following table lists the maximum cable lengths and number of
devices with single-ended I/O circuits allowed on a daisy-chain

Providing adequate cooling
The enclosure design must ensure adequate cooling for the
drive. The maximum ambient temperature is 50°C.
The drive’s product ma nual (32661-001) describes how to evaluate the air-flow design. The evaluation consists of ensuring that
the case temperature of certain critical components remains
within acceptable limits during drive operation.
We recommend orienting the drive or directing the air flow in a
way that creates the least amount of air-flow resistance while
providing air flow above the circuit boards and around the head
and disc assembly (HDA). Also, choose the shortest possible
path between the air inlet and exit. This minimizes the distance
traveled by air that is heated by the drive and by other nearby
heat source s.
Figure 4 shows two design approaches with one or more fans
used to generate air flow. The air-flow patterns can be created
by the fans either pushing or drawing air. The overall flow pattern
can be directed from front to back, back to front, or side to side.

Mounting the drive and connecting cables
Do not touch the connector pins or any components on the control board without observing static-discharge precautions.
Always handle the drive by the frame only.
The drive may be mounted in any orientation (horizontally, vertically, and any combination thereof); however, you must ensure
that the drive receives adeq uate air flow f or cool ing.
1. Mount the drive to the host sys tem’s chassis using four 6- 32
UNC screws. Two mounting holes are in each side of the
drive and there are four mounting holes in the bottom of the
drive.
The maximum length that the screws should extend into the
chassis mounting holes is 0.15 inch (3.81 mm), measured
from the outer surface of the chassis. Tighten the screws
down e venly. Do not over-tighten or force the scr ew if it does
not seem to screw in e asily, because this means the threads
are not properly aligned. In this case, back the screw out
and try again.

Note. Signal ground on the power control board (PCB) and the
head and disc assembly (HDA) are connected together i n
this drive and you cannot separate them. The equipment
in which you have mounted the drive is connected
directly to the HDA and PCB without electrically isolating
shock mounts. Maximizing the conductive contact area
between HDA ground and system ground may reduce
radiated emissions.
If you do not want the system chassis to be connected to
the HDA/PCB ground, you must provide a nonconductive
(electricall y isolating) meth od of mounting the drive in the
host system. This may increase radiated emissions and
is the system designer’s responsibility.

There are four possible terminator power (TP) configurations for
“W” model drives (see Figure 14). You will not normally need to
change this option and can leave the drive configured as it was
shipped from the factory.

WC/LC drives
Setting the SCSI ID jumpers
The SCSI ID for “WC” and “LC” model drives is normally set over
the SCSI bus by the host system using connector contacts 39
(ID0), 40 (ID2), 79 (ID1), and 80 (ID3). Users need not install
jumpers to select SCSI ID.
Te rminating th e drive
“WC” and “LC” model drives do not have internal terminators or
any other way of adding internal termination to the drive. External termination for these drives is normally supplied by the host
equipment when terminat ion is required.
