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 M2615/M2616-ES/ESA/ESB OEM MANUAL 41FH5062E-02 24KB data buffer ----------------- To improve system throughput, the IDD contains a 24KB ring buffer. SCSI bus configuration ---------------------- Up to eight SCSI devices can be connected to the SCSI bus, with any combination of the SCSI devices that operate as initiator and that operate as target. Each SCSI device on the bus has its own unique address (SCSI-ID: #n). For input/output operation, a peripheral device attached to the SCSI bus that operates as target is addressed in unit called as logical unit. A unique address (LUN: logical unit number) is assigned for each logical unit. +-------------+ +-------------+ SCSI bus +----------+LUN=0 | Host system +--+Host Adapter +-------+---+ IDD |(fixed) | | | ID #7 | | | ID #0 | +-------------+ +-------------+ | +----------+ | +----------+LUN=0 +---+ IDD |(fixed) | | ID #1 | | +----------+ | +------------+ +---+ Controller +--+----+-- | | ID #2 | LUN0 LUN1 | +------------+ Mean Time Between Failures (MTBF) --------------------------------- The estimated MTBF of the IDD during its life time is 50.000 hours. Failure of the equipment means failure that requires repairs, adjust- ments or replacements. Mishandling by the operator, failures due to bad environmental conditions, power trouble, controller trouble, cable failures or other failures not caused by the equipment are not included. Mean Time To Repair (MTTR) -------------------------- MTTR is the average time taken ba a well-trined service mechanic to diagnose and repair a drive malfunction. The drive is designed for a MTTR of 30 minutes or less. Service life ------------ Overhaul of the drive is not required for the first five years or the first 20.000 hours. Data security at power failure ------------------------------ Integrity of the data on the disk is guaranteed against all forms of DC power failure except a power failure during a write operation. ********************************************************************** G E N E R A L ********************************************************************** FUJITSU => GDT Tips & Hints about ICP controllers and other peripherals ======================================================== Tagged queues and Fujitsu M 26xx harddisks ------------------------------------------ Fujitsu Harddisks of the M26XX series do not support the SCSI-II feature tagged queues. You should disable this feature in the initialize disks menue of the GDTSetup program. An inquiry command shows, that the harddisk supports tagged queues (this is why you can enable it in the GDTSetup) but this is not true as stated by Fujitsu Germany.
