The drive use M3 screws which should not extend into the drive frame by more than 3mm or damage will occur. Frame clearance --------------- There should be a gap of at least 0.5mm between the drive PCA and any adjacent system components to allow for cooling. Cooling ------- Cooling should be provided to keep the DE surface temperature (measured at the centre of the top of the drive) below 65*C. 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). ********************************************************************** F E A T U R E S ********************************************************************** FUJITSU M2704/05/06SA JUMPER SETTING Media Defects ------------- Before the unit leaves the factory, media defects are listed on the MEDIA DEFECT LIST. This list is written on the media in the SA space which is a reserved area of the disk. All media defects found during manufacture are mapped out during the format process so the drive will appear defect free to the user when first shipped. Any media defects that occur once the drive is installed may be mapped out by the operating system. WARNING Magneto-Resistive Read heads are a significant factor in the achievement of very high capacities in small form factor hard disk drives. The MR head must be electrically biased in order to function, and Fujitsu use +5.5VDC on these drives. The voltage is generated by the drive electronics from the normal +5VDC and +12VDC rails, so standard power supplies and connectors may be used. With the MR head biased in this way, it becomes important to avoid the possibility of discharge between the head and the media, so, in order to ensure operational reliability, the disk enclosure (DE) and hence the platters themselves are also biased to +5.5VDC resulting in zero potential difference between head and platter. This means that the outer casing of the DE is set at +5.5VDC rather than DC Ground as would be the case on a conventional drive. USERS MUST ENSURE THAT THE DISK ENCLOSURE CASING IS NEVER SHORTED TO THE COMPUTER SYSTEM'S FRAME OR DC GROUND. Apple Powerbook... ------------------ If you have a notebook computer, any of the Apple Powerbook range, or are just short of space in your system there is now no need to compromise capacity or performance with physical size. Fujitsu's range of high performance 2.5" drives offer amazingly fast access times and data transfer rates together with storage capacities of up to 520MB. At just 17mm (0.67") high these drives are some of the most compact available and are probably the best engineered disk drives in their class. These drives are extremely versatile and are available with SCSI-2 interface and industry standard mountings and connections to ensure maximum system compatibility.
