This manual contains information for users of the Seagate® Barracuda 4LP SCSI disc drives. It provides support services, performance specifications, and initial setup information. Addi- tional information is available in the Barracuda 4LP Product Manual (part number 77767491). Contact your Seagate sales representative if you need to order this publication.

Electrostatic discharge protection

Caution. Removal of circuit boards by personnel not perform- ing depot repair will damage components and may void the warranty.

All drive electronic assemblies are sensitive to static electricity, due to the electrostatically sensitive devices used within the drive circuitry. Although some devices such as metal-oxide semi- conductors are extremely sensitive, all semiconductors, as well as some resistors and capacitors, may be damaged or degraded by exposure to static electricity.

Electrostatic damage to electronic devices may be caused 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 exposed. 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.
