2. 0 Configuring and mounting the drive
This section contains the specifications and instructions for configuring and mounting the drive.
2. 1 Handling and static-discharge precautions
After you unpack the drive, and before you install it in a system, be careful not to damage it through mishandling. Observe the following standard handling and static-discharge precautions: Caution: · Keep the drive in its static-shielded bag until you are ready to complete the installation. Do not attach any cables to the drive while it is in its static-shielded bag. · Before handling the drive, put on a grounded wrist strap, or ground yourself frequently by touching the metal chassis of a computer that is plugged into a grounded outlet. Wear a grounded wrist strap throughout the entire installation procedure. · Always rest the drive on a padded, antistatic surface until you mount it in the computer. · Do not touch the connector pins or the printed circuit board. Do not touch the printed circuit cable between the circuit board and the head/disc assembly. · Avoid wool or synthetic clothing, carpeting, plastics, and Styrofoam; these items cause static discharge. · Do not remove the factory-installed labels from the drive or cover them with additional labels. Some factoryinstalled labels contain information needed to service the drive. Others are used to seal out dirt and contamination.

2. 2 I/O cable and connector
The I/O connector is a 40-pin connector. The even pins are next to the edge of the printed circuit board; the odd pins are away from the printed circuit board. Make sure the corresponding pin hole on the cable connector is plugged to prevent the connector from being installed upside down.
