There are three possible installation directions, and the mounting
angle must be 5* from the horizontal.

 +-------------------------------------------------------------------+
 | Only the formats of M224XE and M224XC are different; components   |
 | and equipment specifications are the same.                        |
 +-------------------------------------------------------------------+

Frame structure
---------------
The casting/HDA (signal ground) is electrically isolated from the
mounting brackets (frame ground). If this isolation is to be main-
tained within the system, precautions must be taken. An embossed
structure (or any other structure that does not touch the aluminium
base) be used to prevent the aluminium base from touching the frame
ground (FG). The mounting screws should project no more than 4mm from
the outer wall of the drive mounting bracket.

In serial mode, up to seven drives can be connected. To connect
drives, the A cable (control signals) must be connected in series and
the B cables (R/W signals) in parallel. The termination of control
signals must be performed only at the last drive.

The total control cable length in a multi-drive configuration should
not exceed 3m max.

Spindle Motor
-------------
The disk are turned by a direct-drive DC motor. The motor attains a
very precise rotational speed of 3600 rpm, 1%. This precision is
achieved through a feedback circuit which includes Hall-effect
elements mounted within the motor assembly.

Air circulation
---------------
The head assembly has a closed-loop air recirculation system using
the blower effect of the rotating disks to continuously cycle air
through the recirculation filter. This filter traps any dust
generated inside the enclosure. To prevent negative pressure is the
vicinity of the spindle when the disks begin rotating, a breather
filter is attached. This breather filter also equalizes the internal
air pressure with the atmospheric pressure due to surrounding
temperature changes.

Options
-------
The M1054A intelligent disk controller that can control four M224XC/E
drives is available as an option. The M1054A11 controller option can
be used by mounting it directly on the M1054A.

For further specification details, refer to M1054A INTELLIGENT DISK
CONTROLLER OEM MANUAL Document code: B05P-2180-0401A.

FUJITSU M224XC/E DISK DRIVES OEM MANUAL B03P-4805-0102A...04

 Introduction
 ------------
 +-------------------------------------------------------------------+
 | To make system design easier for the user, a simple host inter-   |
 | face controller board based on SCSI is now available as an option.|
 | The drive interface is an Enhanced Small Disk Interface (ESDI),   |
 | with high data integrity and intelligent diagnosis. It has        |
 | superior freedom in sending self-recognition data, and in         |
 | structuring systems.                                              |
 |                                                                   |
 | In addition to the M224XE, the M224XC model, handling the M1054A  |
 | controller format is also available.                              |
 +-------------------------------------------------------------------+
 +-------------------------------------------------------------------+
 | The optional SCSI interface controller board lightens the host    |
 | load in system design. And because the controller board is the    |
 | same shape as the ESDI foot print, it can be mounted on the drive |
 | frame. The drive handling format is mounted on the M224XC.        |
 +-------------------------------------------------------------------+

Media Defects
-------------
Cylinder 0, Head 0 and 1 are defect free.

     M2244C/E....85 or fewer (48 or fewer per surface)
     M2245C/E...120 or fewer (48 or fewer per surface)
     M2246C/E...171 or fewer (48 or fewer per surface)

The maximum defect length is 32 bytes.

All defects are recorded on a self-adhering label and on the media
per the ESDI specification.

When the unit leaves the factory, a printed media defect list for
each drive is sent with it. This information is also written into the
media. The defect list is recorded on cylinders 814 and 822.

Fault lamps
-----------
Drive fault states are displayed by the fault lamps (0, 1, 2, 3).
