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-W6500
Model 60 INSTRUCTION MANUAL (manual number WIN-62-0074)”.
(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-W6500
Model 60 INSTRUCTION MANUAL (manual number WIN-62-0074)”.
(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.)

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.

<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
