eSATA
eSATA allows for full SATA data transfer rates (3 GB/sec) between a drive and the chip set, approximately six times the data throughput of USB.
eSATA on your computer also supports hot-plugging. Hot-plugging allows for device detection without powering down your computer prior to connecting the
device to your computer. When a device is connected, the operating system automatically recognizes the change. However, the computer must be powered
down before removal and/or replacement.
Installing eSATA
1. Remove the computer cover (see Removing the Computer Cover ).
2. Remove the filler panel for the card slot you are using for the eSATA connector.
3. Insert the bracket into the desired eSATA opening.
4. Plug the free end of the eSATA cable into the eSATA connector on the system board (see System Board Components ).
NOTE: See the documentation for the PS/2 serial port adapter for information about the cable connections.
NOTE: Installing filler brackets over empty card-slot openings is necessary to maintain FCC certification of the computer. The brackets keep dust
and dirt out of your computer and maintain the airflow that cools your computer.
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions located in the Product Information Guide.
NOTICE: To prevent static damage to components inside your computer, discharge static electricity from your body before you touch any of your
computer's electronic components. You can do so by touching an unpainted metal surface on the computer chassis.
