Handling precautions/Electrostatic discharge protection

• Disc drives are fragile. Do not drop or jar the drive. Handle the drive only

by the edges or frame.

• Drive electronics are sensitive to static electricity. Keep the drive in its

antistatic container until you are ready to install it. Wear a wrist strap and

cable connected to ground. Discharge static from all items near or that

will contact the drive. Never use an ohmmeter on any circuit boards.

• Turn off the power to the host system during installation (not necessary if

you are using a hot-plug backplane).

• Always use forced-air ventilation when operating the drive.

• Use caution when troubleshooting a unit that has voltages present.

• Do not disassemble the drive; doing so voids the warranty.

• Return the entire drive for depot service if any part is defective.

• Do not apply pressure or attach labels to circuit board or drive top.

What you need

• Screwdriver and four M3 x .5 metric drive mounting screws

• Forced-air ventilation to provide adequate drive cooling

• Backplane host system or enclosure that supports SCA 80-pin connec-

tors.

Note. To operate at LVD transfer rates, you need a backplane that sup-

ports LVD devices.

Multimode interface

This drive can operate in single-ended (SE) or low voltage differential (LVD)

mode. This multimode capability provides backwards compatibility so you

can use it with or without an LVD-capable host adapter or backplane. The

primary benefits of LVD technology include faster transfer rates and

improved device connectivity.

Note. To operate at Ultra2 rates or faster in LVD mode, all devices on the

same bus must be running in LVD mode. If you add any SE device to

the bus, all devices on that bus operate in SE mode.

Caution. Do not mix LVD drives on the same bus with high voltage differ-

ential (HVD) devices—drive damage may occur.

Installation instructions

Savvio

drives have an industry-standard 80-pin Single Connector Attach-

ment (SCA) connector. Drives with these connectors are designed to be

installed in a host system that uses a backplane. In such systems, there are

no cables and the drive options, including SCSI IDs, are set either through

the host interface or on the backplane. There are no jumpers on the drive

that you can use to set the SCSI ID or other drive options. Check your sys

tem’s documentation to determine how to configure the drive in your partic-

ular system. The backplane must provide the SCSI termination for each

drive.

1. Mount the drive in the carrier or tray

LC drives are designed to be attached to a carrier or tray and inserted into

the host system without I/O or power cables.

Savvio drives provide 4 mounting holes on the bottom of the drive, 2 mount-

ing holes on each side of the drive, and 2 mounting holes on the end of the

drive. Refer to the host system’s documentation to determine which holes to

use to mount the drive in the carrier or tray.

Use M3 x .5 metric screws. Do not over-tighten or force the screws.

You can mount the drive in any orientation.

2. Format the drive

The drive has been low level formatted at the factory. You do not need to

perform another low level format on this drive unless you decide to perform

certain diagnostics through the host adapter. If you do decide to perform a

low level format, do not abort the format as this is likely to make the drive

inoperable. A low level format, with verify turned on, will typically take two

hours.

Protect against power failure or other power interruptions during the format.

a. Turn on DC power to the host system.

b. Boot the system from a system floppy, CD, or from a previously

installed hard disc drive if there is one.

c. Format the drive.

Caution. Formatting a drive erases all user data. Be sure that you under-

stand this principle before formatting any hard disc drive. It is not

necessary to format a drive that previously has been used to

store data, unless your intention is to erase all user data.

Seagate

is not responsible for lost user data.

Savvio disc drives are designed to operate with a variety of operating sys-

tems. Please refer to your system or host enclosure manual for information

about formatting and setting up the drive.

Troubleshooting

• Drive does not spin up. Ensure that the host system is supplying power

to the drive’s SCA 80-pin connector and that the drive is fully inserted into

the host system’s backplane connector.

• Computer does not seem to recognize the drive. Verify that the drive

is enabled by the SCSI host adapter setup utility.

Warranty. Contact your place of purchase or our web site (www.seagate.com).

Return Merchandise Authorization (RMA). Before returning the drive, verify that it is

defective. Seagate Worldwide customer service centers are the only facilities autho-

rized to service Seagate drives. Contact nearest center for return procedures and trade

regulations.

Shipping the drive

Back up the data before shipping. Seagate assumes no responsibility for data lost dur-

ing shipping or service. Shipping drive in an unapproved container voids the warranty.

Pack the drive with original box and packing materials. Use no other materials. This

prevents electrical and physical damage in transit.
