Setting terminal: CN3/CN4 (commonly used with connector for external operator panel) Setting terminal: CNH1, CNH2, CNH4, CNH5 and CNH6. Terminating resistor (SCSI) The user MUST NOT change the setting of terminals not described in this section. Setting of CN3/CN4 can be changed when power is on. The following setting is valid after power is turned on again, the SCSI bus is reset, or port is disabled and then enabled: SCSI ID CNH1 LED display requirement ----------------------------- x 1- 2 CLOSE Lights when the IDD is connected to the SCSI bus 1- 2 OPEN Lights when the disk drive is in seek completion status (READY) CNH1 SCSI level ---------------- x 3- 4 CLOSE SCSI-2 3- 4 OPEN SCSI-1/CCS CNH1 SDTR Negotiation Select setting ------------------------------------- x 5- 6 CLOSE SDTR negotiation initiated by IDD 5- 6 OPEN SDTR negotiation is not initiated by IDD When the jumper is shortes, the TARG begins the Synchronous Data Transfer negotiation process. When the jumper is open, The TARG waits for the INIT to begin the negotiation process by sending the SDTR message first. CNH1 SCSI time monitoring -------------------------- RESELECTION phase and ACK signal wait time monitoring x 7- 8 CLOSE Executed 7- 8 OPEN Not executed To prevent SCSI bus infinite loop due to an operation error, do not disable the SCSI time monitoring exept for initiator tests or de- bugging.

(The CHECK CONDITION status caused by the UNIT ATTENTION condition is not reported.) IDD response under the UNIT ATTENTION condition. Sets the response method against the received command when the IDD keeps the UNIT ATTENTION conditions. This mode is set for system re- quirement, and it is recommended that the factory setting be used.

By using the connector CN6 between the drives and setting the required terminals on CNH2, multiple drive synchronization can be utilized. CNH2 Motor start mode ---------------------- x 9-10 CLOSE The motor is started immediately after power is turned on. 9-10 OPEN Starting the motor is controlled with the START/ STOP command. This setting only determines the operation mode when power is turned on. Stopping or restarting the spindle motor is controlled with the START/STOP UNIT command for both modes. By setting this feature, all IDDs spin up when power is supplied. This may cause a surge to the incoming power lines. If multiple IDDs are used in the installation configuration, the SCSI START/STOP command or the Auto Spin-Up Delay function should be utilized. These commands automaticlly increment, based on address, the spin-up function on each IDD. This method is preferred in multiple IDD installations and requires approximately thirty (30) seconds for each IDD installed. CNH2 Auto Spin-Up Delay ------------------------ x 11-12 CLOSE Motor starts immediately with power on 11-12 OPEN Auto spin-up delay (Address dependent) When the Auto Spin-Up Delay is used with Motor Start mode setting CNH2 pins 9-10 shorted), a delay can be used to sequence spin motors in a multiple drive configuration. If Motor Start mode is shorted, this setting selects immediate spin-up or an address dependent delay. The delay is 30 seconds between each SCSI ID address. Address 0 sequences first, followed by 1,2,3,4,5,6,7 to complete (8) devices to be ready. The controller does not know if all devices are present. Care should be given to address each IDD from seven (7) on down sequentially to expediate ready status. CNH2 Write/Read RAM enable --------------------------- x 13-14 CLOSE When the jumper is Shorted (default setting), the WRITE RAM and READ RAM commands are not allowed to be execute.If the IDD receives either commands, it reports CHECK CONDITION status with ILLEGAL REQUEST/Invalid Command Operation Code. 13-14 OPEN When the jumper is OPEN, the IDD accepts and exe- cutes the WRITE/READ RAM commands as described in the Logical Specification. In this case, the data buffer space available for normal READ/WRITE operations is 248KB.

Some setting functions are assigned on the same pins of both CN3/CN4. For the dual port drive M265xHD, CN3 defines the SCSI ID for Port A CN4 defines the SCSI ID and Port Enable for Port B. "Write Protect", "Diagnostic Enable" and "External Reset" are inde- pendent of SCSI port and are selected by CN3 pins (15-20). Pins CN4 (9,10) and CN3 (9-14) are for external operator panel functions.

This pin setting should be utilized through an operator panel equipped with a momentary switch. Normal operation occurs with no jumper installed. ********************************************************************** I N S T A L L ********************************************************************** FUJITSU M2651/53-S/H, M2652/54-S/H/HD OEM MANUAL 41FH5051E-03 Notes on installation ===================== Installation direction ---------------------- horizontally vertically +---------------+ +--+ +--+ | | | +-----+ +-----+ | | | | | | | | | +--+---------------+---+ | | | | | | +----------------------+ | | | | | | | | | | | | X X | | | | | | +------X-------X-------+ | | | | | | +--+-----X---X-----+---+ | +-----+ +-----+ | | X X | +--+ +--+ | X X | +--X--------X---+ X X The tolerance of the angle is 5* from the horizontal plane. Ambient temperature ------------------- The IDD must conform to the environmental requirements. When the IDD is operating, the ambient temperature measured 3 cm from the Disk Enclosure (DE) surface and from the main PCA surface must satisfy the specified requirements. It is recommended that the drive be mounted in such a way that air is moving around the unit at a velocity of approximately 1 m/s (3 ft/s). Multi-drive connection ---------------------- 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. Cable requirements ------------------ The maximum length of SCSI cable is as follows. If more than one SCSI device is connected, the total cable length must not exceed the fol- lowing: Cable length for single ended: 6m Max. Cable length for differential ended: 25m Max. The use of a 25-pair twisted cable satisfying the following require- ments is recommended: Single ended type: Conductor size: 28 American Wire Gauge (AWG) or bigger Characteristic Impedance: 100 to 132 Differential type: Conductor size: 28 AWG or bigger Characteristic Impedance: 100 to 122 Each pair of wires in the 25-pair twisted cable must be connected to pins n and n+1 (where n is an odd number) on the interface connector. Cables having an identical impedance must be use on the same SCSI bus to reduce signal reflection and maintain transmission characteristics When a SCSI device is connected to the SCSI cable except at either end of the cable, connection to the SCSI connector must be at a branchpoint of the cable. If a SCSI device is connected to one end of the SCSI bus, no cable should be connected to the last SCSI device except when the cable has a terminating resistor and the SCSI device does not have a terminating resistor. Check, that system power is off before connecting or disconnecting cables! Be carefull of the insertion directions of the SCSI connectors. With the system in which terminating resistor power is supplied via the SCSI cable, if the drive power is turned on, the overcurrent protec- tion fuse of the terminating resistor power supplier may be blown or the cable may be burnt if overcurrent protection is not provided. Signal ground connector ----------------------- For DC ground, an SG terminal is mounted on the rear of the drive. A DC ground cable may be installed depending on the system require- ments. This cable is generally connected to the ground of the power supply unit. Connection between IDD's may be in a daisy chained. Terminator ---------- All SCSI devices on one bus are daisy-chained with a SCSI cable. A terminating resistor must be mounted in the SCSI device at each end of the SCSI cable. Since a SCSI terminating resistor module is mounted in the IDD on shipment, it must be removed when the IDD is not connected at either end of the SCSI cable. Also, a method for the power supply to the terminating resistor must be selected with the setting terminal on the IDD.

Therefore, if more than one IDD is used, the spindle motors should be started sequentially using one of the following procedures: 1. Issue START/STOP UNIT commands at 30-second intervals to start the spindle motor. 2. Turn on the +12 V DC power in the power supply unit at 30-second intervals to start the spindle motors sequentially. 3. Set the spindle motor start control mode to delay automatic spin up based on the SCSI ID of the IDD. (AN ID=7 spins up immediately. An ID=6 delays 30 seconds. An ID=5 delays 2x30 seconds, etc.) Noise filter ------------ To eliminate ac line noise, a noise filter should be installed at the ac input terminal on the IDD power supply unit. Attenuation: 40 dB or more at 10 MHz. External operator panel connector --------------------------------- CN3 (and CN4 for HD model) Connectors for the external operator panel are provided on the IDD SCSI interface PCBA. They allow connection of an external write pro- tect switch, a Ready/Active LED, an Offline Test Switch, Port Enable Switch, a Port Enable LED and a SCSI ID setting switch. The external operator panel is installed only when required for the system. If it is unnecessary, pins 1 to 8 of the CN3 (and CN4 if applicable) connectors for the external operator panel on the IDD must be set according to desired configuration using shorting plugs.

This allows the IDD to be connected together for spindle sync operation. Spindle sync cable on all IDD SCSI interfaces are daisy-chained with the spindle sync cable. The maximum number of IDD's that can be connected in a single daisy-chained connection is 7 Setting of CN3/CN4 can be changed when power is on. The following setting is valid after power is turned on again, the SCSI bus is reset, or the port is disabled and then enabled. Do not connect or disconnect jumpers after power is on except CN3/CN4 terminals! Confirming initial operations ----------------------------- Do not move the drive when power is turned on! 1. Initial operation in the case where the jumper is set so that motor starts at power-on. When power is turned on, the IDD executes initial self-diagnosis. If an error is detected in the initial self-diagnosis, the LED on the front panel blinks. The spindle motor may start rotating in this stage. When the LED display jumper is removed for "READY status" (see JUMPERS CHN1 1-2 LED requirements), the LED on the front panel lights 45 seconds after power is turned on. At this time, the LED on the front panel blinks while the IDD reads "system informati- on" from the system space on the disk. When the LED display jumper is set for "in connection with SCSI bus" (factory setting), the LED on the front panel remains off (when the initiator accesses the IDD via the SCSI bus, the LED lights). However, the disk drive enters the READY status in 45 seconds after power is turned on. At this time, the IDD reads "system information" from the system space on the disk. 2. Initial operation in the case where the jumper is removed so that motor starts with a START/STOP command. When power is turned on, the IDD executes initial self-diagnosis. If an error is detected in the initial self-diagnosis, the LED on the front panel blinks. The spindle motor does not start rotation until the START/STOP UNIT command for the start is issued. The INIT needs to issue the START/STOP UNIT command to start the spindle motor. The disk drive enters the READY status 45 seconds after the START/STOP UNIT command is issued. At this time, the IDD reads "system information" from the system space on the disk. 3. Items to check if an error occurs. Check that cables are mounted correctly. Check that power and voltages are supplied correctly. Check the setting of each jumper setting terminal. The initial operation depends on the setting of the motor start mode and LED display requirements. If an error is detected in initial self-diagnosis, the LED on the front panel blinks. When the LED display requirements are set to "READY status", the LED is turned off while the drive continues the seek operations. However, since the LED is turned off for only an instant, the LED may seem to be turned on and off or not turned off at all. When the LED display requirements are set to "in connection with SCSI bus", the LED on the front panel lights only when the IDD is connected to the SCSI bus. Howerver, in some commands or when "disconnection from the bus" is enabled, the LED may only be turned on for an instant. Therefore it may seem that the LED blinks or the LED remains off. Since the IDD has the automatic readjustment function of positi- oning (seek) control, it automatically executes the adjustment operations with seek at specific intervals from power on (first adjustment: 2 minutes after power on). When the LED display re- quirements are set to "READY status", the LED on the front panel blinks during the adjustment. Removing drives --------------- Take the drive offline. Disconnect system power before removing the drive. Do not remove mounting screws holding the cables and drive while power is on. Do not move the drive until it completely stops (30 seconds after spindle motor is stopped with START/STOP UNIT command or after power is turned off).

The maximum defect length is 8 bytes. Format capacity --------------- The size of the usable area for storing user data on the IDD (format- ted capacity) varies according the logical data block size. (180, 256, 512, 1024, 2048, 4096, 4160) The data format on the user space can be specified with the MODE SELECT command. High speed data transfer ------------------------ The data transfer rate on the SCSI bus is 3.0 MB/s maximum in asyn- chronous mode and 5.0 MB/s maximum in synchronous mode and 10 MB/s maximum in FAST SCSI synchronous mode. Such a high data transfer rate on the SCSI bus can be usefull with the large capacity buffer in the IDD. The maximum data transfer rate in asynchronous mode may be limited by the response time of initiator and the length of SCSI bus length of cable between INIT and IDD. The maximum data transfer rate in synchronous mode on the single-ended SCSI bus may be limited by the cable length and transmission characteristics of the SCSI bus. Command stack feature --------------------- The IDD has a command stack feature corresponding to up to 7 initia- tors (14 for M265xHD). Therefore, the IDD can accept and stack an input/output command issued by another initiator even if the IDD is executing another command. The stack command is retrieved and exe- cuted in stacked order after the present command has completed. Command queuing feature ----------------------- The IDD supports tagged command queuing in all three forms specified by SCSI (Simple, Ordered and Head of Queue). Each initiator is pro- vided with the capability of having multiple SCSI commands active at the IDD. Up to 256 commands may be queued in the IDD. ********************************************************************** 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.
