Technical data
Maxtor DiamondMax 17 80-160GB Serial ATA Hard Disk Drive 3-7
Installation
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.
–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.
3.4 ATA BUS INTERFACE CONNECTOR (J1, SECTION C)
On DiamondMax 17 80-160GB 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.
To prevent the possibility of incorrect installation, the connector has been keyed. This
ensures that a connector cannot be installed upside down.
3.5 MOUNTING
Drive mounting orientation, clearance, and ventilation requirements are described in
the following subsections.
3.5.1 Orientation
The mounting holes on the DiamondMax 17 80-160GB Serial ATA hard disk drives
allow the drive to be mounted in any orientation. Figure 3-5 shows 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.
Note: Drives can be mounted in any orientation. Normal position is with the PCB
facing down. All dimensions are in millimeters. For mounting, #6-32 UNC
screws are recommended.
