CHAPTER 3 Installation Conditions

3.1 Dimensions

3.2 Mounting

This chapter gives the external dimensions, installation conditions, surface temperature conditions, cable connections, and switch settings of the hard disk drives.

For information about handling this hard disk drive and the system installation procedure, refer to the following Integration Guide.

C141-E144

C141-E250 3-1

Installation Conditions

3.1 Dimensions

Figure 3.1 illustrates the dimensions of the disk drive and positions of the mounting screw holes. All dimensions are in mm.

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 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) Limitation of mounting

Note) These dimensions are recommended values; if it is not possible to satisfy them, contact us.

Installation Conditions

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.

3.2 Mounting

(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 temperature from exceeding 60

°C.

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

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.

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.

Do not drop.

Installation

(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.

3.3.2 Cable connector specifications

Table 3.2 lists the recommended specifications for the cable connectors.

Cable socket

(44-pin type)

89361-144 FCI

For the host interface cable, use a ribbon cable. A twisted cable or a cable with wires that have become separated from the ribbon may cause crosstalk between signal lines. This is because the interface is designed for ribbon cables and not for cables carrying differential signals.

Damage: Interface cable connection

Take note of the following precaution about plugging an interface cable (socket) into the interface connector of the disk drive and plugging the connector into a host receptacle:

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

Figure 3.14 and 3.15 show examples of cable selection using unique interface cables.

By connecting the CSEL of the master drive to the CSEL Line (conducer) of the cable and connecting it to ground further, the CSEL is set to low level. The drive is identified as a master drive. At this time, the CSEL of the slave drive does not have a conductor. Thus, since the slave drive is not connected to the CSEL conductor, the CSEL is set to high level. The drive is identified as a slave drive. drive
