Dell PowerEdge 4300 Installation And Troubleshooting Manual page 145

This section describes the power input connectors and interface connectors on the
backs of most drives.
Figure 9-2 shows the four-pin power input connector , where you connect a DC power
cable from the system power supply. The power connectors are keyed to avoid incor-
rect insertion; do not force two connectors together if they do not fit properly.
A ribbon cable functions as the interface cable for most types of drives. The connec-
tor on the cable may be a header connector (see Figure 9-3) or a latching connector
(Figure 9-4).
