2.4 Interface and connector configuration
The ST52160N and ST52160WC drives are differentiated by their con-
nectors. The ST52160N comes with a standard 50-pin interface connec-
tor and a standard 4-pin power connector. The ST52160WC comes with
an 80-pin blindmate single-connector attachment (SCA-2). The power is
supplied to the drive through the bus. To minimize noise, use shielded
mating connectors.
