Electrostatic discharge protection
Caution. Removal of circuit boards by personnel not performing 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 semiconductors are extremely sensitive,
all semiconductors, as well as some resistors and capacitors, may be
damaged or degraded by exposure to static electricity.

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 surround-
ing charged objects. To avoid damaging drive electronic assemblies, service
personnel must observe the following precautions when servicing the drive:

personnel must observe the following precautions when 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 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.
