2.1Handling and static-discharge precautions

After unpacking, and before installation, the drive may be exposed to potential handling and electrostatic discharge (ESD) hazards. 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.

•Handle the drive by its edges or frame only.

•The drive is extremely fragile—handle it with care. Do not press down on the drive top cover.

•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 remove the factory-installed labels from the drive or cover them with additional labels. Removal voids the warranty. Some factory- installed labels contain information needed to service the drive. Other labels are used to seal out dirt and contamination.

2.2 Jumper settings

2.2.1 Master/slave configuration

You must establish a master/slave relationship between two drives that are attached to a single AT bus. You can configure a drive as a master or slave by setting the master/slave jumpers, shown in Figure 2 on page 19.

These drives support master/slave configuration using the cable select option. This requires a special daisy-chain cable that grounds pin 28 (CSEL) on one of its two drive connectors. If you attach the drive to the grounded CSEL connector, it is a master. If you attach the drive to the ungrounded CSEL connector, it is a slave. To use this option, the host system and both drives must support cable select, and both drives must
