Unpacking, Configuring and Mounting the Drive
This chapter describes how to unpack, mount, configure and connect a BarraCuda. It also describes how to install the drive in systems.
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.
• Keep the drive in the electrostatic discharge (ESD) bag until ready for installation to limit the drive's exposure to ESD.
• 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.
CAUTION
• Always rest the drive on a padded, antistatic surface until mounting 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.
3.2
Configuring the Drive
Each drive on the Serial ATA interface connects in a point-to-point configuration with the Serial ATA host adapter. There is no master/slave
relationship because each drive is considered a master in a point-to-point relationships. 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.
3.2.1
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). Refer to Table 8 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 shown in1.
