Mounting frame structure ------------------------ Generally, SG an FG are connected at one point in the system enclosure. Therefore, use following procedure to maintain the insulation when mounting the IDD: a) Use the frame with an embossed structure or the like to avoid contact between the DE base and FG. Mount the IDD with making a gap of 2.5 mm or more between the IDD and the frame of the system. b) The inward projection of the screw from the IDD frame wall at the corner must be 4 mm or less. Limitatation of side-mounting: When the drive is mounted using side screw holes, do not use the center hole. External magnetic field ----------------------- The drive should not be installed near the ferromagnetic body like a speaker to avoid the influence of the external magnetic field. Ambient temperature ------------------- When the IDD is operating, the ambient temperature measured 3 cm from the disk enclosure (DE) surface and from the PCA surface must satisfy the specified requirement. For the DE surface temperature at opera- ting, the contact temperature at the measurement point must satisfy the specified requirement. Sequential starting of spindle motors ------------------------------------- After the power is turned on to the IDD, a large amount of current flows in the +12 V DC line when the spindle motor rotation starts. Therefore, if more than one IDD is used, the spindle motors should be started sequentially using one of the following procedures to pre- vent overload of the power supply unit. 1. Issue START/STOP UNIT commands at 20-second intervals to start the spindle motors. 2. Turn on the +12 V DC power in the power supply unit at 20-second intervals to start the spindle motors sequentially. Noise filter ------------ To eliminate AC line noise, a noise filter should be installed at the AC input terminal on the IDD power supply unit. The specification of this noise filter is as follows: Attenuation: 40 dB or more at 10 MHz. Circuit construction: T-configuration is recommended. SCSI cable ---------- All SCSI devices on one bus are daisy-chained with an SCSI cable. A terminating resistor must be mounted in the SCSI device at each end of the SCSI cable. The maximum number of SCSI devices that can be connected to the SCSI bus is 8, including the host adapter, IDD, and other SCSI equipment. The maximum length of the SCSI cable is as follows. If more than one SCSI device is connected, the total cable length must not exceed the following. 8-BIT, 6m cable length, Single-Ended 16-BIT, 3m cable length, Single-Ended (Up to 6m is allowable for 5 MB/s or less). 8/16-Bit, 25m cable length, Differential For the SCSI cables, the use of 25- and 34-pair twisted pair cables satisfying the requirements in the following table is recommended. +----------------+-----------------------+----------------------+ |Requirements | 8-bit SCSI (25-pair) | 16-bit SCSI (34-pair)| +----------------+-----------------------+----------------------+ |Conductor size | 28 AWG or bigger | 30 AWG or bigger | +----------------+-----------------------+----------------------+ |Characteristic | 90 to 132 | |impedance | | +----------------+----------------------------------------------+ |Twist pair cable| Pins n and n+1 Pins n and n+33 | |condition | (n: odd number) | +----------------+----------------------------------------------+ DC ground --------- The DC ground cable must always be connected to the IDD because no faston terminal dedicated to SG is provided with the IDD. Therefore, when SG and FG are connected in the system, it is necessary to connect SG and FG at the power supply or to connect SG of the power supply to FG of the system. External operator panel ----------------------- The external operator panel is installed only when required for the system. If it is unnecessary, pins 01 and 02 of CN20 and pins 01 to 06 of CN4: connector for the external operator panel on the IDD must be opened. SCSI bus configuration ---------------------- Up to eight SCSI devices operating as an initiator or a target can be connected to the SCSI bus for the 8-bit SCSI and up to 16 SCSI devices operating as an initiator or a target can be connected to the SCSI bus for the 16-bit SCSI in any combination. For example, the system can be configured as multi-host system on which multiple host computers that operate as initiator or connected through the SCSI bus. Using disconnect/reconnect function, concurrent input/output processing is possible on multi-SCSI devices.

Installation ------------ a) Do not connect or disconnect connectors or change terminal except pin 5-6 of CN6 (offline self-diagnostics)/pin 5-6 of CN7 (write protect) when power is turned on. b) Do not move the drive when power is turned on or until the drive completely stops (for 30 seconds) after power is truned off. Mounting procedures ------------------- Since mounting the drive depends on the system cabinet structure, determine the work procedures considering the requirements specific to each system. The general mounting method and items to be checked are shown below. 1) With a system to which an external operator panel is mounted, if it is difficult to access the connector after the drive is mounted on the system cabinet, connect the external operator panel cable before mounting the drive. 2) Fix the drive in the system cabinet with four mounting screws as follows: - The drive has 10 mounting holes (both sides: 3x2, bottom: 4). Fix the drive by using four mounting holes of both sides or the bottom. - Use mounting screws whose lengths inside the drive mounting frame are 4 mm or less when the screws ae tightened. - When mounting the drive, be careful not to damage parts on the PCAs. 3) Check that the DE (signal ground) does not touch the system cabinet chassis (frame ground). There must be a 2.5 mm or more space between the DE and chassis. Connecting Cables ----------------- Connect the IDD and system with the following cables. - Power cable - SCSI cable - External operator panel cable (if required) - Spindle sync cable The general procedures and notes on connecting cables are described below. Especiallly, pay attention to the inserting direction of each cable connector. WARNING Check that system power is off before connecting or disconnecting cables. Do not connect or disconnect cables when power is on. a) Connect power cable b) Connect the external operator panel (if required for the system) c) Connect the SCSI cable d) Fix the cables so that they do not touch the DE and PCAs, or so that the smooth flow of the cooling air in the system cabinet is assured. NOTES 1. Be careful of the insertion directions of the SCSI connectors. With the system in which terminating resistor power is supplied via the SCSI cable, if the power is turned on, the overcurrent protection fuse of the terminating resistor power supplier may be blown or the cable may be burnt if overcurrent protection is not provided. When the recommended parts are used, inserting cables in the wrong direction can be prevented. 2. To connect SCSI devices, be careful of the connection position of the cable. Check that the SCSI device with the terminating resistor is the last device connected to the cable. ********************************************************************** F E A T U R E S ********************************************************************** FUJITSU M2932/34 SERIES OEM MANUAL C141-E022-01EN 3/1995 510 KB multi-segment buffer --------------------------- Data is transferred between SCSI bus and disk media through the embedded 510 KB data buffer in the IDD. This buffer can be devided into maximum 32 areas. This feature provides the suitable usage environment for users. Since the initiator can control the disconnect/reconnect timing on the SCSI bus by specifying the condition of stored data to the data buffer or empty condition of the data buffer, the initiator can perform the effective input/output operations with utilizing high data transfer capability of the SCSI bus regardless of actual data transfer rate of the disk drive. Read-ahead cache feature ------------------------ After executing the READ command, the IDD reads automatically and stores (prefetches) the subsequent data blocks into the data buffer (Read-ahead caching). The high speed sequential data access can be achieved by transferring the data from the data buffer without reaccessing the disk in case the subsequent command requests the prefetched data blocks. Error recovery -------------- The IDD can try to recover from errors in SCSI bus or the disk drive using its powerful retry processing. If a recoverable data check occurs, error-free data can be transferred to the initiator after being corrected in the data buffer. The initiator software is released from the complicated error recover processing by these error recovery functions of the IDD. Defective block slipping ------------------------ A logical data block can be reallocated in a physical sequence by slipping the defective data block at formatting. This results in high speed contiguous data block processing without a revolution delay due to defective data block. Microcode downloading --------------------- The IDD implements the microcode download feature. This feature achieves easy maintainability of the IDD and function enhancing. SCSI/CCS standard ----------------- The IDD provides not only SCSI basic functions but also the following features: - Arbitration - Disconnection/reselection - Data bus parity - Command set which meets the logical specification of the SCSI CCS (Common Command Set for Direct Access Device) requirements. The SCSI commands can manipulate data through logical block addressing regardless of the physical characteristics of the disk drive. This allows software to accommodate future expansion of system functions. Data security at power failure ------------------------------ Integrity of the data on the disk is guaranteed against all forms of DC power failure except on blocks where a write operation is being performed. The above does not applied to formatting disks or assigning alternate blocks. ECC --- 16-byte data error detection/correction code for the data field. It is possible to on-the-fly, single burst errors with lengths of up to 19 bits, correct single burst errors with lengths of up to 46 bits, correct triple burst errors with lengths of up to 10 bits, and detect quadruple burst errors with lenght of up to 10 bits. Defect list ----------- Information of the defect location on the disk is managed by the defect list. The following are defect lists which the IDD manages. - P list (Primary defect list): This list consists of defect location information available at the disk drive shipment and is recoreded in a system space. The defects in this list are permanent, so the INIT must execute the alternate block allocation using this list when initializing the disk. - D list (Data defect list): This list consists of defect location information specified in a FORMAT UNIT command by the INIT at the initialization of the disk. This information is recorded in the system space of the disk drive as the G list. To execute the alternate block allocation, the FORMAT UNIT command must be specified. - C list (Certification defect list): This list consists of location information on defective blocks which are detected by the verifying operation (certification) of the data block after the initiation when executing the FORMAT UNIT command. The IDD generates this information when executing the FORMAT UNIT command, and the alternate block allocation is made upon the defective block. This information is recorded in the system space of the disk drive as the G list - G list (Growth defect list): This list consists of defective logical data block location information specified in a REASSIGN BLOCKS command by the INIT, information on defective logical data blocks assigned alternate blocks by means of IDD automatic alternate block allocation, information specified as the D list, and information generated as the C list. They are recoreded in the system space on the disk drive. The INIT can read out the contents of the P and G lists by the READ DEFECT DATA command. Formatting ---------- Since the disk drive is formatted with a specific (default) data format for each model (part number) when shipped from the factory, the disk need not be formatted (initialized) when it is installed in the system. However, when the system needs data attributes different from the default format, all sides of the disk must be formatted (initialized) according to the procedures below. The user can change the following data attributes at initialization: - Logical data block length - Number of logical data blocks or number of cylinder in the user space - Alternate spare area size This section outlines the formatting at installation. Setting parameters ------------------ The user can specify the optimal operation mode for the user system environments by setting the following parameters with the MODE SELECT EXTENDED command: - Error recovery parameter - Disconnection/reconnection parameter - Caching parameter - Control mode parameter
