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

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 ambient temperature is measured at a point 3cm from the drive
when it is installed in a cabinet.
Set the air flow so that this temperature does not exceed 45*C.
The standard base surface temperature is 58*C or less. Air circula-
ting in the cabinet should cool the PCA side especially.
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 cross talk is generated when the data transfer rate becomes
very high.
Cable length: 0.5m Max.

Buffer
======
The M261xT supports a look-ahead cache to increase system throughput.
The M261xT 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 M261xT will not be operated for a long time, power consump-
tion can be reduced by using the power save mode.
The M261xT supports two 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.
Actuator lock mechanism
=======================
When the M261xT is not in service, the actuator lock mechanism locks
the head positioning arm to protect it.
Start and stop time
===================
Start time (time from when power is turned on until the IDD is ready)
is 15 seconds or less, and stop time (time to completely stop when
power is turned off) is 25 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.
AC line noise
=============
To eliminate AC line noise, a noise filter of the specifications
given below should be incorporated in the AC input terminal of the
drive power supply.
Attenuation characteristics: 40 dB or greater at 10MHz
Circuit configuration: T type
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. 12 M2611T
max. 24 M2612T
max. 36 M2613T
max. 48 M2614T
Drive BIOS specification
========================
The BIOS specification of the host must meet that of the M261xT in
the number of cylinders, number of heads and sectors per track in
order to make best use of the IDD. The BIOS specification of the IDD
is specified by SET PARAMETERS. The IDD can be used if an appropriate
BIOS specification from the existing drive type table in the host is
selected within the capacity of the IDD. In this case the IDD can be
operated within the limits of the capacity which is selected by the
drive type.

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.
