lowed to minimize or eliminate the risk of personal injury. The warnings point out conditions or practices that may endanger you or others. The cautions point out conditions or practices that may damage the unit, possibly making it unsafe for use.
Always observe the following warnings and precautions:
•Follow all cautions and warnings in the procedures.
•Use sound safety practices when operating, installing, or removing the unit.
•Use caution when troubleshooting a unit that has voltages present. Turn off power to the unit before removing it.
•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. Return the entire drive for depot repair if any circuit board is defective. Removal of circuit boards by personnel not performing depot repair will damage components and may void the warranty.
•Do not separate the head and disc assembly (HDA) from the PCB. 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.
