DISCLAIMER
Failure of the MAN series intelligent disk drive is defined as a failure requiring adjustments, repairs, or
replacement. Fujitsu is not responsible for drive failures caused by misuse by the user, poor environmental
conditions, power trouble, host problems, cable failures, or any failure not caused by the drive itself.
The suffix of the model name of the disk drive varies depending on the electrical requirements, capacity,
and data format at factory shipment of the SCSI, i.e., the interface for connecting the three device types or
host system and the disk drives (Note 1). However, in this manual, the typical model names (Note 2) are
used unless otherwise noted. These disk drives may be called intelligent disk drives (IDD), drives, or
devices in this manual.

Important Alert Items
Important Alert Messages
The important alert messages in this manual are as follows:
A hazardous situation could result in minor or moderate personal injury if the
user does not perform the procedure correctly. This alert signal also indicates
that damages to the product or other property may occur if the user does not
perform the procedure correctly.
Task Alert message Page
Mounting Installation Data loss
For MAN series, Reed Solomon codes are applied for their ECC.
The sector-data is divided into 6 interleaving sectors, and ECC is
performed in each sector where the maximum number of errors (up
to 5 byte) can be corrected. [Total maximum byte: 5 byte
×
6 (
interleave) = 30 byte]
If the error of read sector keeps allowable error byte number,
correction is performed.
However, if error byte exceeds its allowable number, correction
may not be performed properly.
Hot temperature
To prevent injury, do not handle the drive until after the device has
cooled sufficiently after turning off the power. The DE and LSI
become hot during operation and remain hot immediately after
turning off the power.
Data loss
1. The user must not change the setting of terminals not described
in this section. Do not change setting status set at factory
shipment.
2. Do not change the setting of terminals except following setting
pins during the power is turned on.
• Write protect: CN2 9-10 (MP model only)
3. To short the setting terminal, use the short plug attached when
the device is shipped from the factory.
Damage
1. Make sure that system power is off before connecting or
disconnecting cables.
2. Do not connect or disconnect cables when power is on.(except
MC model)
Damage
1. Be careful of the insertion orientation of the SCSI connectors.
With the system in which terminating resistor power is supplied
via the SCSI cable, if the power is turned on, the overcurrent

C141-E128-01EN vii
Task Alert message Page
Mounting Installation protection fuse of the terminating resistor power supplier may
be blown or the cable may be burnt if overcurrent protection is
not provided.
When the recommended parts listed in Table 4.2 are used,
inserting the cables in the wrong direction can be prevented.
2. To connect SCSI devices, be careful of the connection position
of the cable. Check that the SCSI device with the terminating
resistor is the last device connected to the cable.
Data loss
When the SEND DIAGNOSTIC command terminates with the
CHECK CONDITION status, the INIT must collect the error
information using the REQUEST SENSE command. The RECEIVE
DIAGNOSTIC RESULTS command cannot read out the error
information detected in the self-diagnostics.
Caution
1. To avoid shocks, turn off the power before connecting or
disconnecting a cable, connector, or plug.
2. To avoid injury, do not touch the mechanical assembly during
disk drive operation.
3. Do not use solvents to clean the disk drive.
Caution
1. Always ground yourself with a wrist strap connected to ground
before handling. ESD (Electrostatics Discharge) may cause
the damage to the device.
2. To prevent electrical damage to the disk drive, turn the power
off before connecting or disconnecting a cable, connector, or
plug.
3. Do not remove a PCA. This operation is required to prevent
unexpected or unpredictable operation.
4. Do not use a conductive cleaner to clean a disk drive assembly.
5. Ribbon cables are marked with a colored line. Connect the
ribbon cable to a cable connector with the colored wire
connected to pin 1.
Damage
Do not open the DE in the field because it is a completely sealed
room.
Data loss
Save data stored on the disk drive before requesting repair. Fujitsu
does not assume responsibility if data is destroyed during servicing
or repair.
Caution
Never open the disk enclosure in the field. Opening the disk
enclosure in the field may cause an irreparable fault.

CHAPTER 1 GENERAL DESCRIPTION
1.1 Standard Features
1.2 Hardware Structure
1.3 System Configuration
This chapter describes the feature and configuration of the intelligent disk drives (IDD).
IDDs are high performance large capacity 3.5 type fixed disk drives with an embedded SCSI controller.
The interface between the IDD and host system is based on SCSI (Small Computer System Interface)
standard [ANSI X3.131 - 1986: Small Computer System Interface (SCSI), ANSI X3.131-1994: Small
Computer System Interface - 2 (SCSI-2)].
The flexibility and expandability of the SCSI, as well as the powerful command set of the IDD, allow the
user to construct a high-performance reliable disk subsystem with large storage capacity. Refer to SCSI
Logical Interface Specifications for details.

1.1 Standard Features
(1) Compactness
Since the SCSI controller circuit is embedded in the standard 3.5 type fixed disk drive form factor,
the IDD is extremely compact. The IDD can be connected directly to the SCSI bus of the host
system.
(2) SCSI/CCS standard
The IDD provides not only SCSI basic functions but also the following features:
•Arbitration
•Disconnection/Reconnection
•Data bus parity
•Command set which meets the logical specification of the SCSI CCS (Common Command
Set for Direct Access Device) requirements (Rev. 4.B)
The SCSI commands can manipulate data through logical block addressing regardless of the
physical characteristics of the disk drive. This allows software to accommodate future expansion
of system functions.
(3) 8-bit SCSI/16-bit SCSI
The IDD has 16-bit data bus width (16-bit SCSI), which have the wide transfer function suitable
for SCSI-2. This is also available as 8-bit data bus only MP model.
For the ultra SCSI model, number of connectable SCSI devices on the same SCSI bus is varied as
follows.
•8-bit SCSI: 8 drives max.
•16-bit SCSI: 16 drives max.
(4) High speed data transfer
Such a high data transfer rate on the SCSI bus can be useful with the large capacity buffer in the
IDD.
•8-bit SCSI: The data transfer rate on the SCSI bus is 40 MB/s maximum in
synchronous mode.
•16-bit SCSI: The data transfer rate on the SCSI bus is 160 MB/s maximum in
synchronous mode.
