CARE OF YOUR FUJITSU DRI VE

Careful handling and installation of your disk drive is paramount to the longevity of the unit. Serious damage can occur to the internal
mechanisms if forces outside the environmental specifications are exerted to the casing. In transportation, always use the original packing in
which the drive was supplied and avoid sharp changes in temperature to minimise the risk of condensation.

INSTALLATION

1. ORIENTATION–The drive can be installed in each six surface down orientations. Inclination from vertical or horizontal should not

exceed 5

°

.

2. MOUNTING SCREW INSTALLATION–When the mounting screw holes on the side of the drive are used, be sure to use the two pairs
of outer holes. Do not use the center hole in conjunction with only one of the outer holes. The screws must not penetrate the drive by more
than 6.35 millimeters. Impact caused by the electric driver must be within the device specifications.

3. COOLING–Allow space above and below the drive to provide an adequate air flow. Fan cooling is recommended. The disk enclosure
temperature measured at center of base cover (Label side), should never exceed 55°C.

Reference value:
MAN series... An air flow with a velocity of more than 0.1 m/s is required in an environment of 30°C. (Center of DE cover

≤ 55

°C)

(at 200 IOPS) An air flow with a velocity of more than 0.3 m/s is required in an environment of 35°C. (Center of DE cover

≤ 55

°C)

An air flow with a velocity of more than 0.5 m/s is required in an environment of 40°C. (Center of DE cover

≤

55°C)

An air flow with a velocity of more than 1.0 m/s is required in an environment of 45°C. (Center of DE cover

≤

55°C)

MAM series... An air flow with a velocity of more than 0.6 m/s is required in an environment of 30°C. (Center of DE cover

≤

55°C)

(at 250 IOPS) An air flow with a velocity of more than 0.9 m/s is required in an environment of 35°C. (Center of DE cover

≤

55°C)

An air flow with a velocity of more than 1.3 m/s is required in an environment of 40°C. (Center of DE cover

≤

55°C)

An air flow with a velocity of more than 1.9 m/s is required in an environment of 45°C. (Center of DE cover

≤

55°C)

4. TERMINATION–A terminating resistor should be installed externally at both ends of the SCSI bus.

5. TERMINATION POWER–TRMPWR must be supplied to the terminating resistor for correct operation. This can be supplied from

either the drive, except for MC model or the SCSI bus. If only MC model drives are connected to the SCCI bus, TRMPWR should be
supplied externally.

6. ATTACHING THE CABLES–To avoid possible damage to the drive, make sure the direction of the connector matches.

CAUTION: Warranty may be avoided if damage to the connector is caused by wrong insertion.

Handling

1. Never drop. Handle with care.

2. Never move the disk drive while the disks are spinning. This is when the drive is powered on and also immediately after power off. Refer

to the Start/Stop specification for your drive.

3. Always turn off the power before connecting or disconnecting the interface cable. The same applies to changing any of the switches or
terminal settings except if the Write protect switch is present on MP model drives.

4. Never place the drive in the vicinity of strong magnetic fields such as monitors, televisions, or loudspeakers.

5. Never use any cleaning agents or liquids on the drive.

6. Always use an antistatic mat and wrist strap when handling the drive. Hold the drive by the Base casting and never touch the components

on the PCA.

7. Never remove any labels from the drive and do not deface them in any way; these labels are part of the disk drive design.

8. Never open the disk enclosure for any reason. There are no serviceable parts inside. This will also invalidate any warranty.

9. Always pay close attention to the mounting specifications such as sway space and cooling. If the temperature difference between storage

location and installation locations is more than 10°C, leave the drive in the new location for at least two hours for Temperature acclimation.
This minimises any risk of condensation forming on the drive.

The Drive needs NO preventative or periodic maintenance during its life time if properly used in the correct environment.
