                        The short RPS function enables the drive to generate an
                        interrupt to the master during the time that the heads are
                        over any port of the RPS pulse.

                ON      Disable
                        As the Extension, RPS pulse width and skew are not
                        transferred, only a short RPS function is available. This
                        switch must be turned on before power is administered,
                        otherwise the Selective Reset with Reset Drive must be
                        issued.

 (As viewed from cable side of connector)
                                        1 + 12 V
                                        2 + 12 V RTN
                                        3 +  5 V RTN
                                        4 +  5 V


 Notes on Installation
 =====================

 Installation direction: The drive may be installed either PCA down
                         or on edge. Inclination from vertical
                         should be less than 5*.

 Mounting screws:        Either side or underside mounting may be
                         used. Standard drive use M3 screws but some
                         special models and US versions use 6/32 UNC.
                         Screws should not protrude from the drive
                         frame by more than 3mm or damage may occur.

 Frame clearance:        There should be a gap of at least 2.5mm
                         between the drive and the system mounting
                         frame on all sides to provide adequate sway
                         space for shock protection.

 Grounding:              It is strongly recommended that the Disk
                         Enclosure is connected to the system frame
                         ground via the 'faston' connector on the back
                         of the drive.

 Cooling:                Cooling should be provided to keep the DE
                         surface temperature (measured at the centre
                         of the top of the drive) below 55*C.

FUJITSU  M2652P  NOTES ON INSTALLATION


 Media Defects
 ============
 Media Defect List:
 Before the unit leaves the factory, media defects are listed
 on the MEDIA DEFECT LIST. This list is attached to the Disk
 Enclosure and is also written on the media in a reserved
 area of the disk.


 NOTE 1:
 It is recommended that the media defect list be used when formatting
 the drive before use. Any media defects that occur once the drive
 is installed may be mapped out by the operating system. See system
 documentation for details of the defect management schemes available.

 Note 1 : Max. media defects at time of shipment:

                                                M2652P, 600 or less

 Note 2 : No track has more than 4 defects.

 Note 3 : Cylinder 0 heads 0 - 2 and cylinder 1892 head 19 are defect
          free areas.

 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.
