FUJITSU  INSTALLATION CONDITIONS SCSI

 Mounting in Cabinet
 -------------------
 Note the following points regarding mounting of the HDD in a cabinet.
 If circumstances prevent the HDD from being mounted as explained
 below, contact to distributers, reseller, or our sales offices.

 - Mount the HDD in the specified orientation.

 Mounting the HDD in an orientaion other than the specified one may
 adversely affect the temperature or may cause unexpected mechanical
 stress to the HDD. This may lead to a failure to guarantee the
 reliability level stated in the device specifications.

 - Use the specified mounting screw holes.

 Mount the HDD using the mounting screw holes for each model.

 If the HDD is attached by a means other than screws or with screws
 but not at all specified locations (four locations), unexpected
 vibration or shock may be applied to the HDD or the HDD may
 mechanically resonate. This may lead to a failure to guarantee the
 vibration and shock resistance levels stated in the device
 specifications.

 - Use mounting screws of appropriate length.

 A screw shorter than appropriate length is likely to loosen, causing
 the HDD to drop off the cabinet.

 A screw longer than appropriate length may touch the HDD body,
 causing external vibration or shock to the HDD body. This may lead to
 a failure to guarantee the vibration and shock resistance levels
 stated in the device specifications.

 - Ensure clearance between the HDD and the cabinet.

 Be sure that there is a minimum 2.5 mm clearance between the HDD and
 the cabinet. Failure to do so may block ventilation and adversely
 affect the operating temperature of the HDD. It may also cause the
 HDD to touch the cabinet, which may then induce electrical noise or
 transmit external mechanical vibration or shock directly to the HDD
 body. This may result in degraded HDD performance and reliability.

 Pay special attention to those models whose DE potential is not zero
 volatage. If this type of model contacts the cabinet connecting the
 DE to zero volatage, data errors or device faults will occur.


 Grounding
 ---------
 In an HDD with a frame, the DE and frame are electrically isolated
 from each other.

 The DE is connected to signal ground (SG); the frame is connected to
 frame ground (FG). Isolating the DE and frame in this way prevents
 the adverse effects of external electrical noise.

 Generally, a computer system uses some means of connecting SG and FG
 at one point in the system. The method used may vary depending on the
 system structure or environmental conditions.

 The DE potential in some models is not zero volatage. Be careful not
 to ground the DE body of this type of model.


 SCSI cable connection
 ---------------------
 Do not confuse the connector orientation when connecting the SCSI
 cable. Connecting the cable in the wrong orientation may blow the
 fuse of the SCSI device that supplies power to the terminating
 resistor. If the SCSI device has no fuse, misconnection may destroy
 the SCSI cable.


 Power-off
 ---------
 When power is turned off, a dynamic brake stops the rotating spindle
 motor. This requires a given time until the motor is completely
 stopped.

 Applying vibration or shock to the HDD while the spindle motor
 rotates after power-off may damage the HDD.


 Connecting and Disconnecting Interface Connector (2.5-inch HDD)
 ---------------------------------------------------------------
 The printed circuit board assembly of the 2.5-inch HDD is about 0.9
 mm thinner than that of conventional HDDs. When connecting or
 disconnecting the interface connector, push or pull the connector
 straight so as to not give excess stress to the printed circuit board
 assembly. Never force a connector. Excess stress may cause the
 printed circuit board assembly to warp or crack, resulting in poor
 (or no) contact.


 Hot Plug (SCSI Device)
 ----------------------
 Our HDDs are designed to support the hot plug feature. However, a
 drop in output voltage, output interruption, or noise may be caused
 while the HDD is starting. To minimize these symptoms, it is
 recommended that a discrete power supply be installed for each HDD.

 Also, connection or disconnection of the HDD may cause noise on the
 interface signal line and cause an interface malfunction.

 To prevent such a failure, connect zero volatage (SG) first, then
 connect the interface line, and finally connect the power line.
 Reverse the procedure when disconnecting the HDD.

 When disconnecting the HDD, do not apply vibration or shock to the
 HDD, before the power is turned off. This may disturb control of the
 head positioning and degrade data read-write performance.

 In the worst case, applying excess shock may damage the head or disk,
 resulting in data destruction.

 If there is a chance that the power to the HDD containing the
 terminating resistor will be turned off, design the system so that
 power to the terminating resistor (TERMPWR) is supplied from another
 SCSI device. Generally, TERMPWR is supplied from the initiator
 (host).
