Note. Throughout this manual the Medalist 1080sl SCSI is
referred to by its model number, ST51080N.
Application. YourSeagate® drive is designed for IBM and IBM-
compatible personal computers, Macintosh and other systems
using the SCSI interface.
Turn off the system power before attempting any installation.
Static discharge. Observe the followingprecautions:
•Keep the drive in its static-shielded bag until you are ready to
complete theinstallation.Donotattach anycablestothedrive
while it is in its static-shielded bag.
•Handle the drive by its edges or frame, and do not touch the
I/O connector pins or the circuit board.
•Before handling any components, put on a grounded wrist
strap, or ground yourself frequently by touching the metal
chassis of a computer that is plugged into a grounded outlet.
•Use antistatic padding on all work surfaces.
•Avoid static-inducing carpeted areas.
Drive handling. The drive is extremely fragile—handle it with
care. Do not attach labels to any part of the drive.
Inspection. After you are familiar with the handling precautions
listed above, inspect the drive. If it appears to be damaged, call
your distributor or dealer immediately.
Warranty. See your authorized Seagate distributor or dealer.
Maintenance and repair. Seagate drives do notrequire mainte-
nance. The head/disc assembly is sealed; if you break the seal,

you voidthe warranty. Seagate customer service centers are the
only facilitiesauthorized to repairSeagate drives. Seagate does
not sanction any third-party repair facilities.
Shipping. Keep your original box and packing materials for
transporting or shipping your drive. The box has a

Approved Package
label. Shipping a drive in a nonapproved
container voids the warranty. Call your authorized Seagate dis-
tributor to purchase additional boxes.
Radio and television interference. This product complies with
ClassBlimitsforradionoiseemissionsfromcomputerequipment
as set out in the radio interference regulations of the Canadian
Department of Communications.

Configuring the drive
Required materials:
2-mm jumper connector (supplied as spare jumpers)
Your Seagate drive is configured for operation using the options
jumper block (J8) shown in Figure 1 on page 6. The settings for
theavailableconfigurations areshowninFigure2onpage7.The
options jumper block (J8) allows you to:
•Set the SCSI ID
•Connect a remote LED
•Enable or disable parity
•Enable or disable the drive’s terminator
•Select the termination power source
SCSI ID settings. Each device on the SCSI bus must be as-
signed a unique SCSI ID. The drive uses pin-pairs1 and 2, 3 and
4, and 5 and 6 on the options jumperblock (J8) forassigning the
ID. The chart in Figure 2 shows you how to place the jumpers to

assign ID values0 through 7. Be sure that the ID you choose is
not used by another device on the SCSI bus.
YourSeagate driveis shippedby the factory configuredas SCSI
ID 3—jumpers are attached to pins 3 and 4 and pin 5 and 6. You
must reconfigure the SCSIID if another device is assigned SCSI
ID 3 or if you are making the drive the bootable drive. The
bootable drive must be Drive C. It must be assigned the ID
number your SCSIadapterrecognizes as the first positionon the
bus. Usually, this is SCSI ID 0 (refer to your SCSI host adapter
documentation).
If installing your new drive puts more than two drives on the bus,
your SCSI adapter may require thatyou install a device driver or
that you reconfigure its onboard BIOS. Refer to your SCSI
adapter’s user guide for instructions on how to install the third
drive.If a device driver isrequired, it will beprovided bythe SCSI
adapter manufacturer.
Remote LED. You can connect a remote LED to the drive using
pins 9 and 10 on jumper block J8. Connect the LED ground wire
(usually the black wire) to pin 9.
Remote start. This setting causes the drive to wait for a specific
commandfromthehostbeforeitstartsorstopsthespindlemotor.
Parityenable.Parityisamethodthatissometimesusedforerror
detection. The drive is shippedwith parity enabled.
Terminators. The drive is designed with single-ended drivers
andreceiversandmustbeusedwithotherSCSIdevicesthatuse
single-ended drivers and receivers. These systems require that
terminators be used at both ends of the SCSI bus to ensure the
integrity of the signal. The drive has built-in terminators that can
be enabled or disabled as required. It is shipped with the termi-
