CARE OF YOUR FUJITSU DRIVE
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.
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 Write protect switch on NP 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 printed circuit board.
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. Doing so voids 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.
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 5.0 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 60°C. See Table 1.
Table 1. Reference value of airflow
Environmental temperature
Required velocity of airflow
35
°
> 0.1 m/s
40
°
> 0.5 m/s
45
°
> 0.9 m/s
50°
> 1.5 m/s
4. TERMINATION–
A terminator should be installed externally at both ends of the SCSI bus.
5. TERMINATOR POWER–
Terminator power must be supplied to terminator for correct operation. This can be supplied from either the
drive, except for NC model or the SCSI bus. If only NC model drives are connected to the SCCI bus, terminator power 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.
