 Switches locations
 ==================

 x = Switches are set from factory



 SW1  IRQ14/RSVD switch
 ------------------------
         1     OFF    After exchange Pin 29 = IRQ14
         2     ON                    Pin 31 = Reserved

         1     ON     Normal status  Pin 29 = Reserved
 x       2     OFF                   Pin 31 = IRQ14

 This operation is to exchange settings of pin 29 and 31 to eliminate
 cross talk influence in the host interface cable.


 SW1  Slave present mode / Active mode
 ---------------------------------------
 x       3     OFF    Active mode
         4     ON

         3     ON     Slave present mode
         4     OFF

 This plug should be set in Active mode on daisy-chained connection
 of both M261xET.

 The logical information of setting plugs is subject to change without
 prior notice.


 SW2  MASTER/SLAVE drive system
 --------------------------------
         1     OFF    SLAVE side of 2-drive system
         2     ON

         1     ON     MASTER drive
 x       2     OFF


 SW2  1-drive/2-drive system
 -----------------------------
         3     ON     2-drive system
 x       3     OFF    1-drive system


 SW2  Write protect (provided as an option)
 ------------------------------------------
         4     ON     Write protected
 x       4     OFF    Write enabled


 SW2  I/O channel ready (IOCHRDY)
 --------------------------------
         5     ON     Pin 27 = IOCHRDY
 x       5     OFF    Pin 27 = Reserved

 When the data transfer rate of the host becomes very high (near
 7.4MB/s or more), the M261xET must provide wait state to synchronize
 data transfer. This setting is used to output IOCHRDY to pin 27 of
 the host interface.


 SW2  ECC bytes
 --------------
         6     ON     4 bytes
 x       6     OFF    7 bytes

 In 4Byte ECC mode, the READ LONG/WRITE LONG command can be executed
 successfully only under the following conditions:

   -> READ LONG -> WRITE LONG sequence is only acceptable
   -> The sector number of READ LONG and WRITE LONG must be the same
   -> The number of sector on WRTIE LONG must be the same one that
      host issued to the drive on READ LONG.

 If the drive is installed in any of the above three installation
 directions, the level deviation must not exceed 5*.

 Never install PCA to the top!


 Ambient temperature
 -------------------
 The operating temperature range for the IDD in a cabinet is specified
 at a distance of 3cm from the IDD. Design the air flow in the cabinet
 to keep.
 The maximum ambient temperature with in 45*C.
 The air circulation in the cabinet must be designed so that the PCA
 side of the IDD is particularly cooled. The cooling effect should be
 confirmed in measuring the surface temperature of the specific IC
 and DE.

 Cable requirements
 ------------------
 The cable of twisted pairs and neighboring line separated individu-
 ally is not allowed to use for the host interface cable. It is be-
 cause that the location of signal lines in these cables is not fixed
 and so the problem on the crosstalk among signal lines may occur.

 Cable length: 0.5m Max.

 Buffer
 ------
 The M261xET supports a look-ahead cache to increase system throughput
 The M261xET uses 56KB of the cache to read and 6KB to write and a 2KB
 area to download sequencer programs.


 Data transfer rate
 ------------------
 A maximum transfer rate of 7.4MB/s is accomplished with a 30MHz clock
 signal and high-speed buffer management. When the data transfer rate
 becomes near 7.4MB/s or more, the host must recieve IOCHRDY signal
 and maintain the transfer synchronisation by setting a wait state.


 Power save mode
 ---------------
 When the M261xET will not be operated for a long time, power consump-
 tion can be reduced by using the power save mode.

 The M261xET supports 2 power modes which are selectable by the POWER
 command: idle mode and power save mode. In the power save mode, power
 is supplied only to the controller circuit, the spindle motor circuit
 and the drive control IC. Power to the other components is shut off
 by the power FET. Thus low power consumption is accomplished. In this
 mode, the spindle keeps rotation for hot restart.


 Start and stop time
 -------------------
 Typical start time (time from when power is turned on until the IDD
 is ready) is 8 seconds or less, and typical stop time (time to com-
 pletely stop when power is turned off) is 17 seconds or less.


 Power on/off sequence
 ---------------------
 The +5V and +12V power supplies are monitored by the voltage check
 circuit. The circuit allows a write current to flow only when the
 both voltages are normal. Accordingly, no power sequence is required.
 This is for protection of the content of the medium.

 Power consumption
 -----------------

            Steady state         6.4W
            Power save state     3.5W

 Steady state includes SEEK, WRITE and READ operation

 Mean Time Between Failures (MTBF)
 ---------------------------------
 The MTBF is defined as follows:

                            Operating time
          MTBF = -----------------------------------------
                 Number of equipment failures in the field

 Operating time is the total time duration during which the power is
 on, excluding preventive maintenance.
 Failure of the equipment means a failure that requires repair, ad-
 justment, or replacement, excluding preventive maintenance. Errors
 by the operator, failures due to power failures, controller faults,
 cable faults, bad environmental conditions, or other failures not
 caused by the equipment itself are not included.

 The IDD is designed for an MTBF of 50.000 hours.


 Mean Time To Repair (MTTR)
 --------------------------
 MTTR is the average time taken by a well-trained service engineer to
 diagnose and repair a unit malfunction. The IDD is designed for a
 MTTR of 30 minutes or less.


 Service life
 ------------
 Overhaul of the drive is not required for the first five years.


 Data protection against power failure
 -------------------------------------
 Integrity of the data on the disk is guaranteed against all forms of
 abnormal DC power except a power failure during writing.


 Media Defect
 ------------
 When a physical track contains two ore more bad sectors, all sectors
 in the track are given BAD flags in formatting before the M261xT is
 shipped.
 As regards media defect, it defines with number of bad tracks as
 follows. (provided that CYL0, HD0 is defect free)

 Number of bad tracks per drive:  max. 24 M2612ET
                                  max. 36 M2613ET
                                  max. 48 M2614ET


 System configuration
 --------------------
 Up to two IDDs are connectable.
 In principle, perfect operation cannot be guaranteed in case of
 daisy-chained combination (2-drvie system) of M261xET drive and other
 manufacturer's drive.


 Drive BIOS specification
 ------------------------
 As BIOS has limitation of number of cylinders (  1024), a host cannot
 be operated by physical parameters. Therefore, logical/physical
 translation (emulation) is needed, a host has to use M261xET by logi-
 cal parameters. BIOS specifications are defined by SET PARAMETERS
 command which a host issues. A customer who can modify FIXED DISK
 PARAMETER TABLE in the BIOS selects parameter freely and can set BIOS
 specification. However, the parameter must be selected within the
 storage capacity which M261xET has. And it is possible that customer
 uses M261xET by selecting appropriate DRIVE TYPE in the BIOS. In this
 case, M261xET works in the storage capacity which customer selected.
 Logical parameter which can use without loss of physical capacity of
 M261xET is shown below:

                           M2612ET M2613ET M2614ET
      --------------------+-------+-------+-------
      Number of Cylinders |  667  |  667  |  667
      --------------------+-------+-------+-------
      Number of heads     |    8  |   12  |   16
      --------------------+-------+-------+-------
      Sectors per track   |   33  |   33  |   33

 Since LOW LEVEL FORMAT is performed with these parameters, whole data
 area of M261xET can be formatted. M261xET is formatted with physical
 parameters at factory shipment.

 When M261xET is operated by TEST PROGRAM (Bench Mark Test etc.) which
 is for measurement of the performance of HDD, according to BIOS spe-
 cifications, actual performance may not be measured. However, the
 result of Bench Mark Test etc. and the performance of the actual use
 are not always equal. BIOS specification needs to decide that result
 of file access depending on systems is evaluated synthetic.

 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.
