Safety guidelines xiii

Hitachi Compute Rack 220H CRU Replacement Guide

Laser beam

• On this product, a Class 1 laser product is installed. Do not look directly at

the laser beam. Do not look at the laser beam using an optical
instrument.

• Under the laser module cover, a laser beam is being emitted. Do not

remove the cover of an unused board.

Requirements for the product

Install the product on a fixed rack. Do not lean against the product or stand
on it. Do not install the product in a place with weak floors and walls.
Do not subject the product to excessive vibration. That can drop and fall the
product, leading to failure.

Installing the equipment in a rack

To install or remove the system equipment in or from the rack cabinet,
always get help from at least one other person or use tools. If the system
equipment has to be installed on 31U and above of the rack cabinet or it is
already installed there, call for maintenance personnel instead of attempting
to install or remove it. Defective installation may cause the system
equipment to fall, resulting in injury or equipment failure.

Using a rack cabinet

When using a rack cabinet, do not place anything on the system unit mounted
on the cabinet and do not use the top of the system unit mounted on the
cabinet as a work bench. A heavy object placed on top of the system unit on
the cabinet may fall, resulting in injury.

Locking the rail into place

Be sure to pull out the equipment until it locks into place. If not, the
equipment may move unexpectedly, which causes you to get injured such as
your finger caught in the gap.

Contact with metal edges

When moving the equipment or adding parts, take care not to hurt yoursel f
on the metal or plastic edges. You can wear cotton gloves to protect your
hands.

xiv Safety guidelines

Hitachi Compute Rack 220H CRU Replacement Guide

CAUTION: Risk of Explosion if Battery is replaced by an Incorrect Type.
Dispose of Used Batteries According to the Instructions.

Handling of batteries

Improper battery type

Since maintenance personnel should change batteries, do not change them
yourself. Follow the instructions described below. Inappropriate handling can
result in injury because the battery can overheat, burst, and catch fire.

• Do not put the battery on charge.

• Do not short out the battery.

• Do not disassemble the battery.

Storing batteries

When storing batteries, apply adhesive tape on the terminals for insulation. If
the batteries are stored without insulation, the terminals can contact each
other to cause a short-circuit and overheat or burst, leading to injury or fire.

If you do, a short circuit can be

Precautions against damage to equipment

Insertion of foreign objects into the equipment

Do not allow clips, pins or any other metal items or flammable items to enter
the equipment through a vent or by any other means. Continuing to operate
the equipment with foreign objects could cause failure.

Impact from falling

Do not fall the equipment or hit it against another object. It can cause internal
deformation and deterioration. Operating the equipment under such
defective conditions can cause failure.

Vent

A vent is used for preventing rise in temperature inside the equipment. Do
not block the vent by placing or leaning an object. If you do, the temperature
rises, which can cause failure. Check and clean ventilation holes periodically
to keep the dust from gathering on them.

Contact with connection terminals

Do not touch connection terminals, such as a connector with your hand or any
metal item. Do not insert any objects such as wire into them. Do not place the
equipment in a place with metal pieces.
developed, causing equipment failure.

Moving between two locations with a temperature differential

When you move the equipment from one location to another, a significant
temperature gap between the two locations may cause condensation on the
surface or inside the equipment. Operating the equipment with condensation
inside can cause a failure in equipment. Leave the equipment at the new
location for several hours until the equipment temperature conforms to that
of the new environment before you start using it. When you move the
equipment from an environment with temperature 5 degrees Celsius to that
with 25 degrees Celsius, for example, leave it for about two hours.

Adding and connecting to peripheral devices

Use only peripheral devices which are explicitly listed as supported in the
manual, and always follow the instructions in the manual. Using devices other
than those mentioned above would cause a failure in peripheral devices and
equipment due to the difference in connection specifications.

xvi Safety guidelines

Hitachi Compute Rack 220H CRU Replacement Guide

charge might cause

Radio interference

When you install the equipment next to another electronic device, the radio
waves may interfere with each other. In particular, a television set or a radio
in the vicinity may make a noise.

Magnetism generator

Do not place a device that generates strong magnetism, such as a magnet or
a speaker, near the equipment. Doing so can cause a system unit failure.

Handling HDD/SSD

An HDD/SSD is a precision instrument. Handle it car efully when you use it.
Inappropriate handling could result in HDD/SSD failure.

Failed HDD/SSD

• If you attempt to replace failed HDD/SSD using an incorrect procedure or

failed alternative disk, data on the disk array can be corrupted. Back up
the data before replacing the drive.

• If you attempt to replace normal HDD/SSD, data on the disk array can be

corrupted. Only replace the failed HDD/SSD.

• Replace the failed HDD/SSD with turning on the system unit. Otherwise,

data on the disk array can be corrupted.

Static electricity

Discharge static electricity by touching metal door knob or wear cotton gloves
whenever you handle a component. Otherwise, the device might fail.

Residual electric charge

When you change the configura tion of the sys tem unit (DIMM , fan, PCI card,
or peripherals), disconnect all the power plugs and wait 30 seconds and more
before the procedure. Otherwise, residual electric
malfunction.

Safety guidelines xvii

Hitachi Compute Rack 220H CRU Replacement Guide

Aluminum electrolytic capacitors

An aluminum electrolytic capacitor has a limited service life. Do not use it
past its service life. Otherwise, leakage or depletion of the electrolyte may
cause smoke or electric shock. To avoid such hazardous situations, replace
limited-life parts once they are past their designated service life.

Distribution board

Install a distribution board close to an entrance/exit to protect the devices in
your computer system and to serve as an emergency power breaker.

Signal cables

• Route cables not to trip over them. Tripping over cables could cause

injury or failure of devices connected to the equipment, and also could
cause loss of valuable data.

• Do not place heavy items on the cables. Avoid routing cables close to a

thermal appliance. If you do, it could cause damage to cable sheaths,
resulting in failure of the connected devices.

Before turning off the power

• Follow the prescribed procedure for power operation. Power input or

output not according to the prescribed procedure may cause problems on
the system equipment.

• Before turning off the power, confirm that all devices connected to the

equipment stop. Turning off the power during operation of the equipment
may cause equipment failure or data loss.

• When you are using an OS which requires the shut down procedure, be

sure to finish the shut down procedure before turning off the power.
Otherwise, data may be lost.

xviii Safety guidelines

Hitachi Compute Rack 220H CRU Replacement Guide

Rack Mount Safety Consideration

• Elevated Ambient Temperature

If installed in a closed or multi-unit rack assembly, the operating ambient
temperature of the rack environment may be greater than room
ambient. Use care not to exceed the rated maximum ambient
temperature of the unit.

• Reduced Air Flow

Installation of the equipment in a rack should be such that the amount of
airflow required for safe operation of the equipment is not compromised.

• Mechanical Loading

Mounting of the equipment in the rack should be such that a hazardous
condition is not achieved due to uneven mechanical loading.

• Circuit Overloading

Consideration should be given to the connection of the equipment to the
supply circuit and the effect that overloading of the circuits might have
on overcurrent protection and supply wiring. Appropriate consideration
of equipment nameplate ratings should be used when addressing this
concern.

• Reliable Earthing

Reliable earthing of rack-mounted equipment should be maintained. Pay
particular attention to supply connections other than direct connections
to the branch circuit (e.g. use of power strips)."

The ON/OFF status of this switch does not affect the operation of the system.
Every time you press the SERVICE switch, the MAINTENANCE LEDs will change
the code to display as follows.

Figure 1-5: MAINTENANCE LEDs indicate pressing of SERVICE s w itch

switch (number: press
count)

When you intend to press a SERVICE switch, be careful not to press the
POWER switch. The system will be shut down if the POWER switch is
pressed.

When an AC cable is connected and the system unit gets supplied with
AC power, both SERVICE LEDs on the front side and on the rear side of
the system unit blink for about 60 seconds. During this period, the
MAINTENANCE LEDs are turned off.

So you will have to wait the system to start until the LEDs finish
blinking if you press the POWER s witch while the SERVICE LEDs are still
blinking.

Do not directly connect between the management interface connector
and a network interface connector 1 or 2 using a LAN cable. If you do,
the system unit does not work properly.

• The link speed and duplex of the management interface are
specified to auto-negotiation. Therefore, also specify
auto-negotiation to the LAN ports both of a console, terminal and a
switching hub which connected to the management interface.

• We recommend you use the management interface at
100BASE-TX. If the links speed of the management interface is 10
Mbps (10BASE-T link established, the Link LED is OFF), malfunction
may occur in communication. In this case you need to reconfigure
the network connected to the management interface.

• If you find the communication is unstable, turn off the system unit,
shut down the AC power by, for example, disconnecting the AC
cable, wait 30 seconds or more, and then reconnect AC power and
turn on the system unit.

Setup after maintenance

This chapter describes setup required after maintenance conducted due to a
system component failure.

 Notice of maintenance by maintenance person
 Changing a network adapter's MAC address
 Restoring the Web console or Remote Console setting
 BIOS resetting
 Windows BitLocker recovery password

Setup after maintenance 5-1

Hitachi Compute Rack 220H CRU Replacement Guide

Notice of maintenance by maintenance person

Hitachi Data Systems basically provides the latest version of components, BIOS
and firmware, when replacement is required for some components due to
system failure.

As required, unreplaced components or parts, BIOS or firmware might be
updated to the latest version.

Changing a network adapter's MAC address

The MAC address individually owned by a network adapter will change when a
LAN card, motherboard or LAN mezzanine is replaced.

In the following cases, the work for recognizing a new MAC address is required:

• If the peripheral equipment of a destination provides fixed MAC address

management:
To update the MAC address of the peripherals, restart the peripherals after

replacing the motherboard or LAN component and turn on the system unit.

• If a user program or an application program manages a MAC address:

If a user program or an application specifies management of MAC address
values, update data to a new MAC address after replacing the motherboard or
LAN component.

• If you use LAN extended functions:

The LAN extended functions share one MAC address with two network
adapters which are primary card and secondary card.
Delete the setting of LAN extended functions before replacing the
motherboard or LAN component. After replacing a component, set again the
LAN extended functions.

For details on how to use the LAN utility, see Windows Server 2008 R2 LAN
Extended Functions User's Guide.

5-2 Setup after maintenance

Hitachi Compute Rack 220H CRU Replacement Guide

Restoring the Web console or Remote Console settings

The server management settings as the Web console and the Remote Console
application will be lost when a motherboard is replaced.
For this reason, if either the Web console or the Remote Console application is
used, restore the server management settings from the Web console.

The server management settings should be backed up and kept in advance in
preparation for a failure.

For the backup and restoration of server management settings, see Hitachi
Compute Rack 210H/220H Remote Management User’s Guide.

Depending on the fault status, the BMC network settings of the
management network interface might be returned to the factory
defaults. In this case, reconfigure the BMC network.

BIOS resetting

System BIOS or RAID BIOS settings might be returned to the factory defaults
when a motherboard or a RAID card is replaced.

In this case, reset the BIOS settings using the BIOS setup utility, such as "Setup
menu" or "MegaRAID WebBIOS".
If you change the BIOS settings from the factory defaults, note down all the
changed setting values after replacement in case of failure.

For system BIOS and RAID BIOS settings, see Hitachi Compute Rack 210H/220H
BIOS Guide.

Similarly, BIOS settings of a PCI card might be returned to the factory
defaults when replace a PCI card.

For the BIOS settings of an optional PCI card, see Optional PCI card
instruction manual.

Setup after maintenance 5-3

Hitachi Compute Rack 220H CRU Replacement Guide

Windows BitLocker recovery password

If the Windows BitLocker Drive Encryption is in use, cancel drive encryption in
advance when replacing a motherboard or a RAID card.

After replacing component, make a reconfiguration of drive encryption.
In case of a failure that causes the OS not to boot, it is impossible to cancel the

encryption. In this case, make recovery by entering a "recovery password" after
replacing the component.

• Windows BitLocker Drive Encryption is available when an optional
TPM board (EQ7000-Y/EQ7000-R) is installed in the system unit.

• Strictly manage the recovery password. I f the recovery password is
lost, the OS will be unbootable or data will be inaccessible.
