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.
•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 the circuit board or to the top of the drive.
Electromagnetic compliance
•See the Safety and Regulatory Agency Specifications page, part number 75789512, which was shipped with this installation guide.

•Host system with Serial Attached SCSI (SAS) host adapter or backplane
Installation instructions
1. Mount the drive in the host system carrier or tray
Most SAS host systems (including enclosures) provide a way to insert the drive using a carrier or tray, which allows the drive to be
Mount the drive to the carrier or tray provided by the host system using four M3 x 0.5 metric screws. When tightening the screws, use a maximum torque of 4.5
Note. SAS drives are designed to be attached without I/O or power cables; however, you may also connect the drive using
2. Insert the drive
Slide the carrier or tray into the appropriate bay in your host system. This connects the drive directly to your system’s SAS connector. The SAS con- nector is normally located on a SAS backpanel.
Note. There are no jumpers or terminators on the drive. Power is supplied through the SAS connector.
3. 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. Low level formats can take up to 60 minutes for ST973401SS models, or 30 minutes for ST936701SS models.
Protect against power failure or other power interruptions during the format.
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.
Operating systems
SavvioTM disc drives are designed to operate with a variety of operating systems. Please refer to your system or SAS host adapter (controller) man- ual for information about formatting and setting up the drive for use with your particular operating system.
Hot plugging the drive
This drive features hot plugging capabilities which allows you to insert and remove the drive without powering down the host system.
Drive startup options
The drive’s motor will start spinning the discs based on how the host system is configured to control the spinup sequence of the drives. Most systems that host only a couple of drives enable all of the drives to start up immedi- ately when power is applied to the drives. Systems hosting larger numbers of drives may be configured to start drives at various times to avoid over- loading the capabilities of the host system’s power supply.
If you want to change the startup option for the drive, please refer to the documentation provided with your SAS host adapter or host system.
Troubleshooting
•Drive does not spin up. Remove and then reinsert the drive into the drive bay on the
•Computer does not seem to recognize the drive. Verify that the drive is enabled by the SAS host adapter setup utility.
