Installation Conditions

3.1 Dimensions

Figure 3.1 illustrates the dimensions of the disk drive. All dimensions are in mm.


*1 The PCA and connectors are not included in these dimensions.

*2 Dimension from the center of the user tap to the base of the connector pins

*3 Length of the connector pins

*4 Dimension from the outer edge of the user tap to the center of the connector pins

*5 Dimension from the outer edge of the user tap to the innermost edge of the connector pins

3.2 Mounting

3.2 Mounting

(1) Orientation

The disk drives can be mounted in any direction.

(2) Frame

For information on mounting, see the "FUJITSU 2.5-INCH HDD INTEGRATION

GUIDANCE (C141-E144)."

The MR head bias of the HDD disk enclosure (DE) is zero. The mounting frame is connected to Signal Ground (SG).


Use M3 screw for the mounting screw and the screw length should satisfy the specification in Figure 3.2.

The tightening torque must be 0.49N

• m (5kgf

• cm).

When attaching the HDD to the system frame, do not allow the system frame to touch parts (cover and base) other than parts to which the HDD is attached.

3.2 Mounting


Because of breather hole mounted to the HDD, do not allow this to close during mounting.

Locating of breather hole is shown as Figure 3.3.

For breather hole of Figure 3.3, at least, do not allow its around

φ 3 to block.

Installation Conditions

(4) Ambient temperature

The temperature conditions for a disk drive mounted in a cabinet refer to the ambient temperature at a point 3 cm from the disk drive. The ambient temperature must satisfy the temperature conditions described in Section 1.4, and the airflow must be considered to prevent the DE surface cover temperature from exceeding



Provide air circulation in the cabinet such that the PCA side, in particular, receives sufficient cooling. To check the cooling efficiency, measure the surface cover temperatures of the DE. Regardless of the ambient temperature, this surface cover temperature must meet the standards listed in Table 3.1. Figure 3.4 shows the temperature measurement point.

Figure 3.5 Service area

Data corruption: Avoid mounting the disk drive near strong magnetic sources such as loud speakers. Ensure that the disk drive is not affected by external magnetic fields.

Damage: Do not press the cover of the disk drive. Pressing it too hard, the cover and the spindle motor contact, which may cause damage to the disk drive.

Static: When handling the device, disconnect the body ground

(500 k

Ω or greater). Do not touch the printed circuit board, but hold it by the edges.

(6) Handling cautions

Please keep the following cautions, and handle the HDD under the safety environment.

Installation Conditions


General notes

ESD mat

Wrist strap

Use the Wrist strap.

Shock absorbing mat

Place the shock absorbing mat on the operation table, and place ESD mat on it.

Do not hit HDD each other.

Do not stack when carrying.

Do not place HDD vertically to avoid falling down.

Figure 3.6 Handling cautions

Do not drop.



(1) Please use the driver of a low impact when you use an electric driver.

HDD is occasionally damaged by the impact of the driver.

(2) Please observe the tightening torque of the screw strictly.

3.3.3 Connector specifications for host system

Table 3.2 lists the recommended specifications for the host interface connectors.

Table 3.2 The recommended connector specifications for the host system

Segment Name Model

SATA interface and power supply

Host receptacle 67492-0220 (Molex) or compatibles


The above connector specifications for the host system indicate only that its mating with the SATA interface connecter is confirmed.

Accordingly, the number connecter insertion/extractions including hot plugging is not guaranteed.

The connection reliability per number of insertion/extractions varies with the condition of the connection with the host system.

Therefore, we recommend that the customer evaluate the connecter on the customer's system and select it from the several choices including its equivalents (compatibles).

3-10 C141-E245

3.3 Connections with Host System

3.3.4 SATA interface cable connection

The cable that connects the disk drive to the host system must be compliant with the Serial ATA 1.0a specification.

3.3.5 Note about SATA interface cable connection

Take note of the following precaution about plugging a SATA interface cable into the SATA interface connector of the disk drive and plugging the connector into a host receptacle:

When plugging together the disk drive SATA interface connector and the host receptacle or SATA interface cable connector, do not apply more than 10 kgf of force in the connection direction once they are snugly and securely in position.
