3.4 COMBINATION CONNECTOR (J1)
3.4.5 SATA BUS ADAPTER
3.4.5.1 SATA Bus Connector
Some PC motherboards have a built in SATA bus connector. These SATA bus connectors are compatible with Maxtor DiamondMax Plus9 hard disk drives.If the motherboard has a SATA connector, simply connect a 7 pin SATA cable between the drive and the motherboard.
3.4.5.2 Adapter Board
If your PC motherboard does not contain a built-in SATA bus interface connector, you must install an SATA bus adapter board and connecting cable to allow the drive to interface with the motherboard. Maxtor does not supply such an adapter board, but they are available from several third-party vendors.
Please carefully read the instruction manual that comes with your adapter board to ensure signal compatibility between the adapter board and the drive. Also, make sure that the adapter board jumper settings are appropriate.
3.5 COMBINATION CONNECTOR (J1)
J1 is a three-in-one combination connector. The drive’s DC power can be applied to section A or B. Do not connect both a and b to power at the same time. The SATA interface (7-pin) uses section C. The
connector is mounted on the back edge of the printed-circuit board (PCB), as shown in Figure 3-6.

CAUTION: Do not connect both A and B to power at the same time

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 in Table 3-3 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.
• 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 3.3 V, then all V33 pins must be terminated.
Otherwise, it is optional to terminate any of the V33 pins. If a device uses 5.0 V, then all V5 pins must be terminated.
Otherwise, it is optional to terminate any of the V5 pins.
• If a device uses 12.0 V, then all V12 pins must be terminated.
Otherwise, it is optional to terminate any of the V12 pins.
3.5.1 ATA Bus Interface Connector (J1, Section C)
On the Maxtor DiamondMax Plus9 60/80/120/160/200GB AT hard disk drives, the SATA bus interface cable connector (J1, section C) is a standard 7-pin SATA.
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.
3.5.2 Orientation
The mounting holes on the Maxtor DiamondMax Plus9 60/80/120/160/
200GB AT hard disk drives allow the drive to be mounted in any orientation. Figure 3-5 and Figure 3-9 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.
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.
Drives can be mounted in any orientation. Normal posi-tion is with the PCB facing down.
All dimensions are in millimeters. For mounting, #6-32 UNC screws are recommended.

(0.198 Inches) 6.35 mm Maximum (0.25 Inches)
CAUTION: The PCB is very close to the mounting holes. Do not ex-ceed the specified length for the mounting screws. The specified screw length allows full use of the mounting hole threads, while avoiding damaging or placing unwanted stress on the PCB. Figure 3-10 specifies the minimum clearance be-tween the PCB and the screws in the mounting holes. To avoid stripping the mounting hole threads, the maximum torque applied to the screws must not exceed 8 inch-pounds.
A maximum screw length of 0.25 inches may be used.
3.5.3 Clearance
Clearance from the drive to any other surface (except mounting surfaces) must be a minimum of 1.25 mm (0.05 inches).
3.5.4 Ventilation
The Maxtor DiamondMax Plus9 60/80/120/160/200GB AT hard disk drives operate without a cooling fan, provided the ambient air
temperature does not exceed 131°F (55°C) at any point along the drive form factor envelope.
FOR SYSTEMS WITH A MOTHERBOARD ATA/SATA ADAPTER
You can install the Maxtor DiamondMax Plus9 60/80/120/160/200GB AT hard disk drives in an AT-compatible system that contains a 40-pin ATA bus connector/SATA on the motherboard.
To connect the drive to the motherboard, use a 40 conductor ribbon cable (80 conductor ribbon cable if using Ultra ATA/66/100 or /133 drive) 18 inches in length or shorter. Ensure that pin 1 of the drive is connected to pin 1 of the motherboard connector. To connect the drive to the motherboard for the Maxtor DiamondMax Plus9 SATA drives, use a SATA cable 1 meter long or shorter. Ensure that pin 1 of the drive is connected to pin 1 of the motherboard connector.
