5.3.2 Attach the Power Supply Cable
If your system does not support hot plugging (see “Hot Plug Support” on page 21), it
must be turned off and unplugged before installing your hard drive. This avoids the
possibility of reversing the polarity of the power connections and eliminating current
surges that can damage either the drive or computer.
Attach the SATA power supply cable to the SATA device plug power connector. The
SATA power connector is keyed to ensure proper insertion.

5.3.3 Attach SATA Interface Cable
You can configure the hard drive two ways:
1. Cable the drive directly to a SATA connector on the motherboard, or
2. Cable the drive to a host adapter card mounted in one of the expansion slots in the computer.
Both configurations use a SATA interface cable.
Make sure the SATA interface cable is no longer than 1 meter (39.37 inches) to
minimize noise that is induced on the data and control buses.

5.4 Serial ATA Latching Connector
This hard drive also allows Serial ATA latching cable connections. The latching
connector provides a secure connection between the drive and the cable connector
via a locking latch mechanism. The new latching connector design has two channels,
one above the power connection and one above the data connection. Latch
alignment with these channels forms an interlock when the latching cable is inserted
into the drive. This latching feature makes the SATA connector more robust and
ensures a click-lock connection which is verifiable even in noisy environments.
