Always observe the following warnings and precautions:
• Perform all maintenance by following the procedures in this
manual.
• Follow all cautions and warnings in the procedures.
• Use sound safety practices when operating or repairing the
unit.
• Use caution when troubleshooting a unit that has voltages
present. Turn off power to the unit before servicing it.
• Wear safety shoes when removing or replacing heavy parts.
• Ensure that the internal temperature of the rack or cabinet
does not exceed the limits defined for the drive when the drive
is mounted in an equipment rack or cabinet. When units are
stacked vertically, pay special attention to the top where tem-
peratures are usually highest.
• Follow the precautions listed above in “Electrostatic discharge
protection.”
• Do not remove any circuit boards from the drive chassis.
Return the entire drive for depot repair if any circuit board is
defective. Removal of circuit boards by personnel not perform-
ing depot repair will damage components and may void the
warranty.
• Do not remove the head and disc assembly (HDA) from the
drive chassis. Return the entire drive for depot repair if the
HDA is defective.
• Do not attempt to disassemble the HDA. It is not field repair-
able. If the sealed HDA is opened by personnel not performing
depot repair, this will damage components and void the
warranty.
