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
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.
•Turn off the power before removing or installing the DC power cable.
•Do not remove any circuit boards from the drive.
•Never use an ohmmeter on any circuit boards.
•When installing the drive on a carrier or tray, discharge the carrier or tray prior to inserting it into the system.
