Before you begin

Verify that the system is switched off and discon- nected from main power before any installation is attempted.

Protect yourself, the drive, and your valuable pro- grams and data by reading the following cautions and warnings.

•Do not unpack drive from its static shielded bag until you are ready to install it in the system.

•Always handle the drive by the frame or casting.

•Do not touch printed circuit board (PCB) or the I/O connector pins.

•Never apply pressure to the PCB or to the drive top cover.

•Do not tamper with sealed top cover. Doing so voids your warranty. The drive contains no user service- able components. See Product Repair section for more information.

•Visually inspect the shipping container for any obvi- ous damage.
