General Installation Guidelines

When you install a drive, you connect two cables—a DC power cable and a
data cable—to the back of the drive. The DC power cable is connected to the
power supply while the other end of the data cable connects an expansion
card or the system board. Most connectors are keyed for correct insertion (a
notch or a missing pin on one connector correspondes to a tab or a filled-in
hole on another connector).
When connecting a SAS or SATA cable, hold the cable by the connector at
each end and press firmly into the connector. When disconnecting a SAS or
SATA cable, hold the cable by the connector at each end and pull until the
connector detaches.
