Switches locations
==================
x = Jumpers are set from factory
SW1 I/O channel ready signal output
------------------------------------
1 ON Output to pin 27
x 1 OFF IORDY output is disabled
Specify wether to output the IORDY signal to pin 27 of the HOST
interface. When the data transfer rate of the host is very high
(around 7.4MB/s), the IORDY signal is output to synchronize data
transfer by inserting wait states.
SW1 Connection to the spindle synchronous signal
-------------------------------------------------
2 ON Connected to HOST interface
x 2 OFF Not connected to HOST interface
SPSYNC line is disconnected
Specify wether to connect pin 28 of the HOST interface
The SPSYNC switch is provided as an option.
SW1 Write-protect
-------------------
3 ON Write-protected
x 3 OFF Write protect is disabled
SW1 7-byte ECC in write/read LONG mode
----------------------------------------
4 ON 7 Byte The number of ECC bytes in LONG mode is
always 7 bytes regardless of the setup of
the host.
x 4 OFF 4 Byte The number of ECC bytes in LONG mode depends
on the setup done with the SET FEATURES com-
and. The default setup after power-on is 4
bytes.

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 3 cm from the IDD. Design the air flow in the cabi-
net to keep.
Pay attention to the air flow to prevent the DE surface temperatue
from exceeding 65*C.
The air circulation in the cabinet must be designed so that the PCA
side of the IDD is particularly cooled.
Multi-drive connection
----------------------
Up to two IDDs are connectable.
Note: To use a daisy-chain configuration (2-drive system), the disk
drives must be connected to an M261xT series machine or an ATA-com-
patible machine in principle. Operation cannot be assured for daisy-
chain configurations with other machines.

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
because 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.
External operator panel connector
---------------------------------
CN5 So that the front panel LEDs can be mounted externally, the
disk drive has an external operator panel connector. The ex-
ternal LED indication is the same as the LED indication on the
front panel of the disk drive.

Media Defect
============
Defect sectors are replaced with alternates when the disk is format-
ted prior to shipment from the factory (low level format). Thus, the
host sees a defect-free device. Alternate sectors are automatically
accessed by the disk drive. The user need not be concerned with
access to alternate sectors.
Known defects, for which alternative blocks can be assigned, are not
included in the error rate count. It is assumed that the data blocks
to be accessed are evenly distributed on the disk media.
Drive BIOS specification
========================
The disk drive uses constant density recording technology (all
cylinders are classified into four areas and the recording density
varies in each area). The number of sectors/track varies with the
area. Therefore, the disk drive constantly performs logical/physical
translation (emulation) and the host must access the disk drive
according to the BIOS specifications (logical parameters).
The number of sectors/track and the number of heads in the BIOS
specifications are defined by the INITIALIZE DRIVE PARAMETERS (or
SET PARAMETERS) command from the host.
Table 6.1 describes the BIOS specifications that allow the physical
capacity of the disk drive to be used most effeciently. The disk
drive has a low-level format with these parameters as shipped from
the factory.
Table 6.1 |M2622T|M2623T|M2624T|
-------------------+------+------+------+
Number of cylinders|1013 |1002 | 995 |
Number of heads | 10 | 13 | 16 |
Sectors/track | 63 | 63 | 63 |
-------------------+------+------+------+
Total capacity | 326MB| 420MB| 513MB|
IF able to change the fixed disk parameter table in the BIOS, the
user can select parameters and incorporate them into the BIOS speci-
fications. However, the selected parameters must satisfy the capaci-
ties listed in Table 6.1.
It is also possible, to select items (within the capacity of Table
6.1) from the existing drive type table in the BIOS of the system.
The disk drive operates as a device of the capacity of the selected
drive type (parameter).
Low-Level Format
================
A low-level format is executed from the factory with the parameters
listed in Table 6.1.
The disk is formatted such that defects are invisble to the host.

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.
