Cheetah 4LP Installation Guide, Rev. B

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.

As a component, this drive is designed to be installed and oper- ated in accordance with UL1950, EN60950, CSA C22.2 950- M89, and VDE0805.

Seagate takes all reasonable steps to ensure that its products are certifiable to currently accepted standards. Typical applica- tions of these disc drives include customer packaging and sub- system design. Safety agencies conditionally certify component assemblies, such as the Cheetah disc drive, based on their final acceptability in the end-use product. The subsystem designers are responsible for meeting these conditions of acceptability in obtaining safety-regulatory agency compliance in their end-use products and for certifying where required by law. A necessary part of meeting safety requirements is the provision for overcur- rent protection on drive SELV supply voltages.

This unit is a component part and as such is not meant to comply with FCC or similar national requirements as a stand-alone unit. Engineering radiated emissions test results are available through the Seagate Safety Department to assist the subsystem designer.
