Serial ATA cables and connectors

The Serial ATA interface cable consists of four conductors in two differential pairs, plus three ground connec-

tions. The cable size may be 30 to 26 AWG with a maximum length of one meter (39.37 inches). See Table 7

for connector pin definitions. Either end of the SATA signal cable can be attached to the drive or host.

For direct backplane connection, the drive connectors are inserted directly into the host receptacle. The drive

and the host receptacle incorporate features that enable the direct connection to be hot pluggable and blind

mateable.

For installations which require cables, you can connect the drive as illustrated in Figure 3.

Figure 3. Attaching SATA cabling

Each connector is keyed to ensure correct orientation.

Drive mounting

You can mount the drive using four screws in the side-mounting holes or four screws in the bottom-mounting

holes. See Figure 4 for drive mounting dimensions. Follow these important mounting precautions when mount-

ing the drive:

•

Allow a minimum clearance of 0.030 inches (0.76 mm) around the entire perimeter of the drive for cooling.

•

Use only M3 x 0.5 mounting screws.

•

Do not overtighten the mounting screws. Maximum torque: 4.0 in-lb (0.4519 N-m).

•

Four (4) threads (0.080 inches, 2.032 mm) minimum screw engagement recommended.

•

Avoid excessive drive distortion when mounting. Refer to the following specifications for stiffness/deflection

information:

Top cover stiffness/deflection

Operating with no performance degradation, emitted noise,

mechanical damage, or hard errors

10 mm probe: 1.02kgf or

5 mm probe: 0.92kgf

Non-operating with no hard errors

20 mm probe: 2kgf at any point of top cover

20 mm probe: 15kgf at top cover edges only
