The following points should be noted:
All pins are in a single row, with a 1.27 mm (.050”) pitch.
• The comments on the mating sequence apply to the case of backplane
blindmate connector only. In this case, the mating sequences are: (1) the
ground pins P4 and P12; (2) the pre-charge power pins and the other
ground pins; and (3) the signal pins and the rest of the power pins.
ground pins P4 and P12; (2) the pre-charge power pins and the other
ground pins; and (3) the signal pins and the rest of the power pins.
• There are three power pins for each voltage. One pin from each voltage
is used for precharge in the backplane blind-mate situation.
• If a device uses 5.0 V, then all V
5
pins must be terminated. Otherwise,
it is optional to terminate any of the V
5
pins.
• If a device uses 12.0 V, then all V
12
pins must be terminated. Otherwise,
it is optional to terminate any of the V
12
pins.

ATA Bus Interface Connector (J1, Section C)
On the QuickView Serial ATA hard disk drives, the Serial ATA bus interface cable
connector (J1, section C) is a standard 7-pin Serial ATA. See Figure 3-4.
connector (J1, section C) is a standard 7-pin Serial ATA. See Figure 3-4.
To prevent the possibility of incorrect installation, the connector has been keyed.
This ensures that a connector cannot be installed upside down.

MOUNTING
Drive mounting orientation, clearance, and ventilation requirements are described
in the following subsections.

Orientation
The mounting holes on the QuickView Serial ATA hard disk drives allow the drive
to be mounted in any orientation. Figure 3-5 and Figure 3-6 show the location of
the three mounting holes on each side of the drive. The drive can also be mounted
using the four mounting hole locations on the PCB side of the drive. Mounting
dimensions are shown in Figure 3-6.

using the four mounting hole locations on the PCB side of the drive. Mounting
dimensions are shown in Figure 3-6.
Note:
It is highly recommended that the drive is hard mounted on to
the chassis of the system being used for general operation, as well
as for test purposes. Failure to hard mount the drive can result in
erroneous errors during testing.
