⚫Operate the equipment by following the instructions and procedures described
in this manual.
⚫Pay attention especially to safety precautions displayed on the equipment or in
this manual. Make sure you follow them. Otherwise, personal injury and
property damage including damage to the equipment may result.
⚫A safety precaution is indicated by a heading as shown below. A heading is
either a safety alert symbol; a word such as “DANGER”, “WARNING”,
“CAUTION”, or “NOTICE”; or a combination of both.
This is a safety alert symbol. This symbol is used to signify
potential hazards that may result in personal injury or death.
Make sure you follow the safety message that follows this
symbol in order to avoid possible injury or death.
DANGER: This symbol is used to indicate imminent hazards that
will highly likely result in serious personal injury or
death.
WARNING: This symbol is used to indicate potential hazards that
may result in serious personal injury or death.
CAUTION: This symbol is used to indicate potential hazards that
may result in minor or moderate personal injury.
NOTICE:This symbol is used to indicate hazards that may result in
equipment or property damage but not personal injury.
The heading “NOTE”is used to indicate a cautionary note about handling and
operation of the equipment.
⚫Do not attempt to perform any operation that is not described in this manual. If
there is any problem with the equipment, call your maintenance personnel.
⚫Read this manual carefully and fully understand the directions and precautions
written in this manual before operating the equipment.
⚫Keep this manual nearby so that you can reference the manual anytime you
need it.
⚫Every effort has been made to specify the best precautions on the equipment
and in the manual. Nevertheless, unexpected incidents may occur. When you
use the equipment, you are asked not only to follow the instructions but also to
use your own judgement on safety.

SAFETY INSTRUCTIONS (Continued)
1. SAFETY WARNINGS IN THIS MANUAL
1.1 Safety Warning Indicated as “NOTICE”
⚫When failure of a drive is predicted, a drive hardware failure is likely to
occur in the near future. We recommend you to back up the data and replace
the drive. For information about how to replace a drive, refer to “HF-W7500
Model 65/60 INSTRUCTION MANUAL (manual number WIN-62-0075)”.
(See page 2-3.)
⚫When OS hung-up occurs, processes on the OS cannot run as scheduled, and
the facility using this equipment may be affected due to delay in processing.
If OS hung-up occurs, resolve it immediately. (See page 2-6.)
⚫If a RAS MCU fails, the RAS software will not be able to monitor and
control the hardware correctly. Stop the equipment and then contact your
system administrator or maintenance personnel. (See page 2-15.)
⚫If this equipment continues to operate while fan failure is detected, internal
parts such as a processor are not cooled down sufficiently, and that may
cause thermal runaway of the system due to malfunction of the equipment or
result in damage to the parts. (See page 3-4.)
⚫When the Hardware status window shows an error in hardware, resolve the
error immediately. (See page 4-2.)
⚫When failure of a drive is anticipated, the drive may experience hardware
failure in near future. We recommend you to back up the data and replace the
drive. For information about how to replace a drive, refer to “HF-W7500
Model 65/60 INSTRUCTION MANUAL (manual number WIN-62-0075)”.
(See page 4-10.)

S-3
SAFETY INSTRUCTIONS (Continued)
⚫If this equipment continues to operate after a fan failure is detected, internal
parts such as processors will not be cooled sufficiently. In such a case,
equipment malfunctions might occur, causing erratic system operation or
damage to components. If possible, enable the automatic shutdown feature.
⚫If the automatic shutdown feature is not used, have a user application detect a
fan failure using a RAS event and shut down the equipment. (See page 5-2.)
⚫Log function exits (asynchronously) without waiting for the data to be
actually written to a log file. That means this function does not return an
error even when writing to a log file fails for some reason. We recommend
important information be recorded in the OS event log. (See page 6-15.)
⚫CPU load increases while memory dump files are being collected. While
CPU load is high, operation of user applications can be disturbed. Make sure
that you do not collect memory dump files using the log information
collection window while the applications for business use are running on this
equipment. (See page 7-4.)
⚫While the equipment is running in simulation mode, monitoring of the actual
hardware status is disabled. Errors including fan failure and abnormal
temperature cannot be detected. You must never use this equipment in
simulation mode for business use. Use the simulation function only for
testing a user application and checking the notification interface of the RAS
software. (See page 8-2.)

PREFACE
This manual describes how to use the Reliability, Availability, Serviceability (RAS) feature of the
HITACHI INDUSTRIAL COMPUTER HF-W7500 Model 65/60 (hereinafter referred to as
“equipment”).
<Organization of this manual>
This manual is organized as follows.
CHAPTER 1 CAPABILITIES OF THE RAS FEATURE
CHAPTER 2 ITEMS MONITORED BY THE RAS FEATURE
CHAPTER 3 SETTING UP THE RAS FEATURE
CHAPTER 4 CHECKING THE HARDWARE STATUS
CHAPTER 5 CONTROLLING THE HARDWARE
CHAPTER 6 LIBRARY FUNCTIONS
CHAPTER 7 FEATURES RELATED TO MAINTENANCE AND FAILURE ANALYSIS
CHAPTER 8 SIMULATING THE HARDWARE STATUS
<Precautions when you use the RAS feature>
● Precautions about a RAS external contacts interface
This manual provides an explanation about a RAS external contacts interface. Note that this
interface is an optional feature.
● Precautions about an event log entry at the startup of the SNMP service
When you enable the SNMP service, a standard feature of Windows®, in order to use remote
notification, an error log entry with event ID 1500 may be recorded at the startup of the SNMP
service. This event log entry is recorded when SNMP trap notification has not been set up. Set
up the trap notification according to “4.5.3 Enabling the remote notification”.
● User Account Control
If User Account Control (UAC) is enabled in Windows® configuration, User Account Control
windows is displayed when you run application or command. In this case, click OK or
Continue.
<Trademarks>
•Microsoft®, Windows®, Windows Server®, Windows NT®, and Visual Basic® are trademarks
or registered trademarks of U.S. Microsoft Corporation in the United States and other countries.
• All other product names (software and hardware) not from Hitachi described in this manual are
registered trademarks, trademarks, or products of their respective owners.

<Note for storage capacity calculations>
● Memory capacities and requirements, file sizes and storage requirements, etc. must be
calculated according to the formula 2n. The following examples show the results of such
calculations by 2n(to the right of the equals signs).
1 KB (kilobyte) = 1,024 bytes
1 MB (megabyte) = 1,048,576 bytes
1 GB (gigabyte) = 1,073,741,824 bytes
1 TB (terabyte) = 1,099,511,627,776 bytes
● As for disk capacities, they must be calculated using the formula 10n. Listed below are the
results of calculating the above example capacities using 10nin place of 2n.
1 KB (kilobyte) = 1,000 bytes
1 MB (megabyte) = 1,0002bytes
1 GB (gigabyte) = 1,0003bytes
1 TB (terabyte) = 1,0004bytes
