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.

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.

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.
Features
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.
