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 (see
"Standard Factory Connectors" on page 13). The SATA power connector is keyed to ensure
proper insertion.

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 com-
puter.
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.

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 against breakage from downward force and ensures a click-lock
connection which is verifiable even in noisy environments.
