Configuring and mounting the drive

This section contains the specifications and instructions for configuring and mounting the drive.
3.1

Handling 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:
• Before handling the drive, put on a grounded wrist strap. 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 mounting it in the computer.
Caution
• 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.
3.2

Configuring the drive

Each drive on the Serial ATA interface connects point-to-point with the Serial ATA host adapter. There is no master/slave
relationship because each drive is considered a master in a point-to-point relationship. If two drives are attached on one
Serial ATA host adapter, the host operating system views the two devices as if they were both "masters" on two separate
ports. Both drives behave as if they are Device 0 (master) devices.
3.3

Serial ATA cables and connectors

The Serial ATA interface cable consists of four conductors in two differential pairs, plus three ground connections. The cable
size may be 30 to 26 AWG with a maximum length of one meter (39.37 in). See Table 6 for connector pin definitions. Either
end of the SATA signal cable can be attached to the drive or host.
For direct backplane connection, the drive connectors are inserted directly into the host receptacle. The drive and the host
receptacle incorporate features that enable the direct connection to be hot pluggable and blind mateable.
For installations which require cables, users can connect the drive as illustrated in Figure 4.
